Can One Use A 36V Battery On A 24V Electric Bike?
An electric bike is a bicycle that is electrically powered. Such bikes come with different speeds and capacities, so it’s best to research before purchasing.
You can use an electric bike for commuting to work or going on long bike rides in the country.
Yes! However, it’s essential to consider the power of the 36V battery and how it will affect your electric bike’s performance. While some electric bikes accept up to 36V, many 24-volt ones do not. This is fine, though, as you can always hook it up to a 24V battery charger for charging.
The 36V battery pack has more energy than the 24V pack, but your electric bike’s speed will still have a limit of 20 km/h.
If you have a 36V battery and need more speed, you can always upgrade your motor, controller, and wheel size.
If you are interested in upgrading the motor, look for a geared motor or a higher KV. You will have to modify the controller to support the higher voltage.
If you have a 24V wheel, you will need a 36V wheel.
This is a general guide to what you can do if you have a 36V battery pack (24V Motor/ 36V Controller) and a 24V electric bike.
You can convert the 24v bike to 30-36v, but your regulator should set the controller voltage so that the motor will run at its full speed and power.
If you use a 24V motor, you cannot control or use a 36v system. You need to select another motor for your electric bike.
The 36V battery pack has more power than the 24V battery, but your electric bike’s speed will have a limit of 20 km/h.
You also need to use a 36V battery charger for charging as the 24V charger will not work.
The 36V battery is harder to find at local shops (but you can search online), so it makes sense to upgrade your entire system if you are interested in increased speed.
If you are more interested in having more reliable bikes, the 36v option will be worth it. The 36V battery has more energy, making your electric bike more powerful.
You should consider modifying the motor controller to handle the increased voltage. If you have a 24V wheel, you will need a 36V wheel.
What Is the Distinction Between 24V And 36V Motors?
Here are a few differences between 24V and 36V motors: 24V motors apply up to 24 volts of power, but people usually use these motors in 120 VAC and 240 VAC systems.
On the other hand, one can find 36V motors in DC (direct current) systems.
The top three-phase 36V motor with brushless DC excitation can do 0-10 amps, while the top five-phase 24V motor with brushless DC excitation can do only five amps.
You can also identify whether a motor is 24V or 36V by looking at the wire size. A 24V motor uses 12 gauge wire, while a 36V motor uses ten gauge wire.
However, there are two types of 36V motors: Series and Parallel.
The Series 36V motor has fewer wires and can accommodate more current than the Parallel 36V motor.
The Series 36V motor can accommodate 0.75 HP, while the Parallel 36V motor can only do 0.5 HP for power and current ratings.
24V motors are usually cheaper than 36V motors, but they can deliver similar torque values depending on their power ratings.
The good thing about 24V motors is that people commonly use them in 120 VAC systems, so you won’t see problems when repairing such systems.
However, one can use 36V motors in DC systems, but they deliver the same torque values as the 24V motors, which are much more expensive.
Will A 12V Battery Power A 36V Motor?
Yes. It’s possible to power a 36V motor with a 12V battery, and this is how you do it.
You can accomplish this in several ways, but the following assumes you have a 12V battery (or several) and a 36V motor.
If, like most people, your motor has other specifications such as outputs, voltage sensitivity, or power net weight/size.
Then please use your discretion when performing these steps – they may not be correct for your particular application.
Also, you can make some measurements differently, depending on your motor and battery.
Using the 12V battery to draw power from the 36V motor. To do this, you need to convert the current over voltage into direct current.
I have a couple of options: Adjustable voltage regulator: This circuit takes the 12V input and converts it into a regulated DC voltage at the desired output for your application.
If you have a 12V battery, then this is all you need. There are lots of these, but they are rather expensive at around $30.
Can A 36V Speed Controller Handle 48v?
Yes. A 36V speed controller will work fine on a 48v electric bike battery. The two volts are not comparable because they refer to two different voltage ranges, so the answer is yes.
Some e-bikes come with a 36V system as standard, but most have 48V.
However, 36V speed controllers have a maximum continuous power output rate of 250W (e.g., the Cycle Analyst).
Because a 48V system delivers double that power, you will get less range from your battery at full throttle – but this is exactly what you would expect.
The other thing to consider is that a 36V system will draw more current than a 48V system to put more load on the battery.
For example, if your battery has a rate of 100Ah and has 1400Wh of capacity, you can expect your system to pull ~500A (1400W x 2 volts = 36Vs).
If you have a 500A draw (say, on some lights), you can use the rating of the lights to estimate how much power they will use.
Can One Charge A 24-Volt Battery With A 36-Volt Charger?
Yes. It’s possible to charge a 24-volt battery with a 36-volt charger as long as its capacity is higher than 24 volts.
A 36-volt charger will only supply 12 hours of current, and it can take up to six hours for a complete charge, so it will be better for charging batteries for cars or emergency power systems.
How long do the batteries last, and what happens when they die? If a battery completely discharges, it can damage the battery and needs replacement.
The voltage will get so low that the electrolyte will spill out of the battery cell, called ‘pitting.’ It causes irreversible damage to the battery and will never work properly again.
If a battery has almost discharged, it may start building pressure in the electrolyte, called ‘death,’ and the electrolyte can leak out of the battery cell.
This could damage your battery and make it unsuitable for an emergency power system.
It’s possible that a small percentage of batteries will not die from too much discharge, but all batteries will eventually die if used in emergency power systems or cars.
If the battery discharges down to a level where the water can no longer pump back into the battery, it will begin to take on water and swell, or ‘run-down.’
In extreme cases, a battery can swell up and burst, called ‘overcharging.’
When they die, they all look the same. The electrodes and separator are starting to corrode and leak electrolytes. You should replace these batteries as soon as possible.
How Do You Trickle Charge A 24-Volt System?
Here is how you trickle charge a 24-volt system:
First, you will need to find out what kind of charging system your electric car has. If it is a lead-acid battery, you would need an alternator that outputs 12 volts for a 24-volt system.
If your electric car has lithium-ion or nickel-metal hydride batteries, you have an onboard charger and do not require an external charger.
Next, the connection is between the positive terminal of the battery and either one post on the trickle charger clamps.
One way to connect the positive terminal on the battery to the post on the trickle charger clamp is by using a small jumper wire. This allows you to connect and disconnect with ease.
However, there are more efficient ways to do this. Another way would be to use a locking T-type connector that has crimped onto a small metal plate (about 3/8” by 1/2”).
If a T-type connector crimps onto this metal plate, you will have no jumping necessary. You can connect the connector to one post, unscrew the plate, and connect it to the other post.
Some people like to use a battery clamp with two posts (one positive and one negative) connected with a T-connector.
This way, they can pick up the positive clamp and connect it directly to the positive lead on their battery.
In either case, you will want to use a trickle charger compatible with your voltage. If you have a 24-volt lead-acid system, use a 12-volt charger so it can still function in the higher voltage system.
How Do You Test A 36-Volt Battery Charger?
You can test a 36V battery charger by using a voltmeter to attach across the wires in the charger.
The voltage regulator will then provide regulated 36 volts to act as a load on the charger. This is a very rudimentary test because it only measures one line of voltage.
But you may want to make this test before buying any charger that reads 36V or for testing.
The first step is to remove your 36V battery from the scooter and then find where you connect to the charger.
Many chargers are 12 volts, so you may need to locate the charger case. The red wire will go positive on the battery contacts, and the black will go to the ground.
The other wire on most chargers is a control wire that allows the attachment of a display unit or other accessories. You can test this wire with a voltmeter to check for voltage.
You will want to connect the red voltmeter lead to one battery charger terminal and the black lead to the ground if the charger has a control line that you can test.
You should note that some chargers may appear similar but have different voltages coming out of them. With a 36V scooter, this charger has 36V coming out of it.
The next step is to test the voltage coming out of the charger. A 36V charger will discharge a 24V battery, so wait until it fully charges.
Once charged, you can then connect the voltmeter leads as shown above and check for a full battery charge.
If your charger reads over 36 volts, this may be a problem.
When you return the charger for warranty service, please bring it with your battery and scooter to show that everything worked before this malfunction.
If you’re trying to understand why your 36V charger wasn’t charging your battery, this is a quick and dirty way to check it. If it’s not in warranty, then there are some basic tests that you can perform.
Why Is My Ezgo Blinking Red?
Your Ezgo blinks red because of a failed diagnostic test. If the diagnostic test fails, replace the control module.
This will cost $70, and one can easily do it at a garage or an online store specializing in Ezgo golf carts.
The failure of the diagnostic test means that your battery can no longer tune your Ezgo’s engine to charge efficiently.
The battery and controller are in your cart’s rear deck and wired together on one of its sub-frames, so you will need both hands free to get this repaired.
You will only be able to replace the battery if you have the qualification and know which parts belong.
You must clean your Ezgo regularly, preventing many problems from occurring.
How Can You Make A 24 36 Volt E-Bike?
E-bikes are a fairly recent innovation, and it’s no wonder enthusiasts are constantly wondering how to build their own.
These bikes make for flawless transportation with incredible power efficiency as electric cars and fewer emissions than gasoline.
Whether you’re an ordinary commuter with a 40-mile round trip commute or someone who is trying to recreate the feeling of being in a racing bike competition;
An e-bike is a convenient solution to high gas prices and a clogged freeway system.
The bikes are efficient and powerful, but their price tag might be enough to scare a potential rider off.
But with a little research and practice, you can build one yourself. Here’s how to do it:
Step 1: Decide On The Size Of Your Bike
E-bike frames come in two styles: step through, pretty self-explanatory, or conventional.
The step-through frames are great for new riders and those who don’t want their clothes getting caught on the way to class or work.
On the contrary, conventional frames make for a more traditional bike experience.
The frame is just one aspect of your bike’s dimensions. As you build your e-bike, consider how big you want it to be.
If it’s your first time building an e-bike from scratch, smaller is usually better since it will be easier to handle, and its lower weight will add more stability.
If you’re a veteran e-bike rider and are already familiar with the size of your bike, look at the frame sizes on your brand’s website before you start.
Step 2: Pick Out Your Motor
The larger the motor, the more power it will have. Don’t worry: you can easily step down to a smaller one for an even better price with a tad of tinkering.
Step 3: Choose Your Battery
The motor size largely depends on the size of the battery. Consider the range and speed you want to achieve when choosing a battery.
You can also find smaller batteries that are good for commuting distances but look for a lithium-ion or nickel-cadmium battery if you’re traveling long distances.
Titanium makes it so durable that you can ride it off a mountain; don’t crash it into anything.
Step 4: Get Your Wheel Size
Most e-bikes come with two-wheel sizes: 20-inch wheels or 26-inch wheels. The smaller the wheel, the easier it gets to turn and handle.
Also, consider the tires that are most suitable for your riding conditions. If you’re riding on uneven surfaces, get bigger tires.
It’ll be easier to control the bike if its tires have more friction with the road.
Step 5: Choose Your Wheelset
Most e-bikes have front-wheel motors. This is because the rider easily controls them, and they create less jerking action along with the bike’s frame.
For those who want more control, use a front-wheel motor. If you want more stability, mount the motor on the rear of your bike.
Step 6: Choose Other Parts For Your Bike
Aside from the frame, motor, and battery, a handful of other options make an e-bike complete. Saddlebags, of course, make for great storage space.
You can also add a trunk to carry even more items around. Also, consider getting a headlight if your bike will travel at night or when the weather is inclement.
A basket might be necessary if you want to go grocery shopping while you’re out on your bike.
If you’re the do-it-yourself type, find that building an e-bike is relatively easy. You’ll not only save money and help the environment, but you’ll also get to spend some time on your bike.
24 Vs. 36 Vs. 48 Vs. 52 Volt Electric Bike specifications
24 Volt Vs. 36 Volt Vs. 48/52 Volt
All electric bikes have to supply about two voltages: 24 volts for the regular quick-charge port and 36 volts for a higher-power port.
Some e-bikes even come with a 48/52 volt port, but that’s just for charging heavy batteries, which aren’t used by most riders. Only 48/52 volt e-bikes require a second power source.
As one of the most powerful and versatile electric bikes on the market, you can use a 36-volt hub motor to get all that power where you need it.
The 36 Volt motor has all the power of the 48/52 Volt hub motors, with more torque and lower RPMs, just like on an Ebike with a 48/52 volt battery.
The 36 Volt motor has more torque at lower speeds than the 48/52 volt motors.
The 36 Volt motor works on both a 24 Volt battery and a 36 Volt battery. You can use the same motor for 24 volts, 36 volts, and 48/52 volt batteries.
One must select wheels used with a hub motor according to voltage. Most big-wheel bikes use a 36V wheel, and smaller wheels are often 24V or 48/52V.
They also sometimes have different diameters, so you’ll need to ensure the wheel has a 36 mm axle dia.
18/36 Volt Vs. 48/52 Volt Hub Motor Sets
Several e-bike manufacturers like Haibike and Atlas offer 48/52 volt hub motor sets compatible with 36-volt battery packs and use the 18V battery pack.
You can use these 48/52 volt hub motors on a 36V pack with additional wiring modifications.
Because of the risk of overheating, some Ebike shops warn their customers not to use the 48/52 volt motors with 36V batteries simply because they are more likely to overheat.
With proper cooling (like a fan), they will run cooler than the 36V model.
If you want the most torque available from one motor, choose a 48-volt motor that comes in two different torques: 80 Newton-meters per kilogram or 60 Newton-meters per kilogram.
The first one will give you better performance at low speeds, and the second one will be more powerful at higher speeds.
36V battery kits are now more affordable than ever.
They enable riders to get the most out of their bike if they want the best Ebike experience on the market, including a 36-volt battery kit on your shopping list.
