, , , ,

Unfortunately,

e-bike batteries are not universal or interchangeable

. An electric bike requires a specific type of based on its voltage (V), amps/capacity (Ah), and other features such as size and weight. For example, you can't put a 48-Volt battery on an e-bike built for a 36-Volt one.

How do I choose an eBike charger?


Divide the amp hours of the battery (10) by the amps of the charger (2) to get the number of hours it will take to charge

. 5 hours, in this example. If you want to charge the battery faster, you'd need to use a charger with more amps.

Can I use a 52V battery on a 48V motor?


As long as you are using a Juiced Bike with an LCD display, the 52V battery can be used

. The 52V battery pack is designed to be interchangeable with that of the 48V bikes that use an LCD display (CrossCurrent S and RipCurrent S). These bikes were actually initially designed to use the 52V system.

How many Ah do I need for my ebike?

Li-Ion battery weight Range (mi)
6-8lbs


20mi (32km)

How long will 48V 20Ah battery last?

In theory, a bike with two riders, loading 150 kg, 48V 20Ah battery pack could run

40 Km

, and a bike with one rider could run 70 km with a smaller accelerator. Accelerator pedal size has a big effect on mileage. The 48V12A battery, theoretically, could run 40-50 kilometers with 300 pounds of cargo.

Will a bigger battery make my eBike faster?

The speed of your is dependent on the battery voltage so

swapping to a battery with higher voltage is one way to go faster

. For example, increasing from a 36v to a 48v battery. Before making a change, make sure your bike can actually handle a higher voltage – otherwise, you risk damaging your controller.

Can I put a higher voltage battery on my eBike?


Ebike power can be boosted by simply turning a ‘pot' screw, disconnecting the power smoother plug or simply fitting a higher voltage battery

. Alternatively, on high spec ebikes where battery and controller are inaccessible, you can fit performance chips.

Can I use a higher Ah battery for my eBike?

The answer to this question is

doubtlessly yes

. The batteries with higher amp hours deliver more power and more performance, allowing the battery to work for a longer time on a full charge as compared to the cells with lower amp hours.

What amp should I charge my eBike battery?

#3 Buy a big ebike battery (20-Ah or more) and charge it at

5-amps

. A big battery solves a lot..they are less delicate and can handle a fast charge. Also with a large enough battery you won't have to worry about charging in the middle of the ride.

Can I use a 42V charger on a 36V battery?

For example, for a 36V 9 Ah lithium ion battery,

it is recommend to choose a 42V charger with maximum output current 3 Amps or less

. Using smaller charging current to charge a lithium ion battery will take longer charging time, but it will be better for battery.

Can you use a 48v charger on a 36V battery?


No!!! The voltage of the charger must be matched to the voltage of the battery system being charged

. A 48 volt charger would see your 36 volt battery system as a very under-charged battery (not being 48 volts) and the net effect would be to damage your batteries attempting to bring them up to 48 volts.

Can you put a 52V battery on a 48V ebike?

Almost all the ebike controllers in the market can handle both 48v and 52v. It's the same for other parts of ebike conversion kit or pre-built electric bicycle.

Any part than works with 48v is compatible with 52v

.

Can I use 60V battery on 48V controller?

Re: How to use a 60v battery pack on 48v motor

You need to know the max voltage charge of your 60V pack to determine if it will work with your setup. What's the specs on the pack? At worst, you will need a new controller, but

if max charge is 60V, then it will work fine without a problem

.

What is the difference between 48V and 52V battery?

The Difference Between 48V and 52V Batteries

The difference between the two is

power and performance

: A 52V battery delivers better performance. A higher-voltage battery provides greater efficiency, with the battery using less electricity to provide the same or better power for the bike.

Is 250 watts enough for ebike?


If you're 100 pounds, a 250-watt motor may be enough for you

. But if you're 220 pounds, a 500-watt motor might be better for you because the top speed somebody on a 250-watt motor at 100 pounds can hit might be pretty close to the top speed somebody that's 250 pounds on a 500-watt could hit.

What does 14 Ah mean on a battery?

AMP HOURS (Ah)

Technically, it's a measure of how much current the battery can deliver in one hour at a useable voltage. For example, a 14Ah 36V battery will provide

14 amps for one hour at approximately 36 volts

. Or 7 amps for 2 hours, etc.

What is the difference between 10ah and 12ah?

The difference between 12ah and 10ah is

the strength of the battery during use

. The 12ah (or amp/hour) is 20% stronger than a 10ah.

What is better 24v or 48V?


If your energy needs are around 1,000 to 5,000 watts, go for a 24 volt system. If your energy needs are over 3,000 watts, go for a 48 volt system

. Large off-grid houses often use 48V.

Is a higher Ah battery better?

As a general rule,

a higher Ah battery is better for delivering more current

, which implies more power in watts. A higher Ah rated car battery will generally deliver more cold cranking amps (CCA), while a deep-cycle battery can deliver medium currents for a longer period of time.

How fast is a 1000w eBike?

While it might not seem that fast when compared to driving, a 1000-watt e-bike equates to a speed of

roughly 35mph

. These powerful e-bikes are typically used for off-roading activities and rough terrain, as opposed to a routine commute.

How do you override the speed limit on a eBike?

As a general rule, you can override the electric bike speed limiter by

covering the pins of the speed sensor in the control connector or by changing the position of the speed sensor so that it is opposite the crank

.

How do you unlock the speed limit on an eBike?

You can use the full power of your electric bike following three methods to remove the speed limiter. The methods are

hand method, disconnect the sensor wiring, and the last one is using bike tools

. Then you can ride at your desired speed on off-road driving, during mountains, or on personal property.

How fast is 500W eBike?

How Fast Does A 500W Electric Bike Go? It is

approx 20 mph

, if your electric bike has a 500 watt motor, it can allow you to reach a top speed of about 20 mph. Because the electric bike with 500W motor is still in Class 1, Class 2 which maximum speed is limited to 20 mph.

What is the difference between 36V and 48V battery?

Battery Volts

A 36V e-bike battery will allow you to draw a lesser critical current, typically around 15 amperes whereas, a 48V e-bike battery will allow more current in the range of 10 – 40 amperes. It means you can go faster with a 48V E-bike battery.

How can I increase the range of my electric bike?
  1. Make sure the EnergyPak is fully charged before you start your ride. The range depends on which EnergyPak you have. …
  2. Always check tire pressure before you start your ride. …
  3. Be smart about how you shift. …
  4. Ride in Eco mode. …
  5. Ride without support.

What does Ah do on eBike?

The other measurement is Ah which stands for

amp hours

. For this one, you can think of duration. The more amp hours (or Ah) you have, the longer the battery lasts on a charge, or in the case of ebikes, the more range you have. So for this example, we will use a DŌST battery.
