Finding the right e-bike battery pack for your electric bike is a little overwhelming, figuring out how much range you can get from these batteries and matching them to the motor systems of your bike is very important.
In our guide below we will cover more about e-bike batteries and how to buy the right one for you, as well as how to look after the battery and troubleshoot it in case of any future issues.
Long ago, e-bike batteries used to be made of lead-acid, but since the motor system and ebike batteries have improved, they are mostly made of lithium-ion or lithium-polymer instead now.
Lead-acid batteries are similar to the batteries used in cars, they were switched out due to their heavyweight and short lifespan.
Lithium-ion batteries are small and can last a long time, lithium polymer batteries are still relatively new but are even more compact than your regular lithium-ion batteries.
The make-up of these batteries always consist of three things; the battery capacity, enclosure and BMS which helps increase its lifespan, we will cover all three parts in greater detail below.
In terms of range, you might be wondering how long your battery will last, however, this can be controlled by numerous different factors such as the power of the battery, to begin with.
In the UK, you will likely have an electric bike with either a 24, 36 or 48V battery power, this will on average produce a range varying between 25 and 70 miles off a single charge.
However, many factors influence how long your ebike battery will last you such as the pedal assist you are using the bike with, how you look after the battery and how often it is used.
Most electric bike batteries will last you around 5 years with good care and frequent use, you can get a feel for your e-bikes battery lifespan by checking its charging cycles before you buy.
Moreover, we have also written an article about the best 3000 watts electric bike conversion kits in 2022.
The battery capacity for electric bikes is typically measured in Wh. On most standard electric bikes you will find they have 400Wh or 500Wh batteries, if you are looking for a lightweight e-bike you might want a smaller capacity battery of around 300Wh which is removable.
If you need a lot of capacity for long-range touring with your electric bike then you might want to consider going for a dual battery system that can even reach up to 1000Wh by carrying two 500Wh batteries.
Apart from deciding the type of battery and its power, you also need to decide where you will put it on the electric mountain bike frame or electric road bikes frame.
You can mount your electric bike battery in three ways; rear rack-mounted, integrated or frame-mounted.
If you want to keep your new electric bike battery in top condition then you need to make sure are doing some electric bike battery basics care.
We have listed our best tips for taking care of all ebike types of batteries below.
It is very common to run into a few battery problems over the time that you have your electric bike, the device might just stop charging or its battery ranges will become more limited over time.
We have covered the basic problems common battery systems have and their solutions below, but before we get into them make sure your e-bike battery pack has some charge first, then we can proceed.
If your e-bike battery is having issues with charging then one of the first places you need to check is the charger itself.
You first want to make sure that they charge you are using for your e-bike battery is correct, these have to match up to your battery, using any old charger will not work and can potentially damage the battery of the bike.
Also check if the indicator lights come on the charge when you plug it in the wall, if not then we know it's the charge which has the problem, not the battery.
To fix this try testing the current with a voltmeter, anything below zero means you need a new bike charger.
The next part to check is the battery itself, make sure that its prongs are nicely lined up and that there are no obvious loose connections that could be stopping the battery from powering up the bike.
If you have left your batter in storage for a while with no charge then this might have caused it to die.
It is also possible that the battery has just reached the end of its lifespan, many only have up to around 1000 charge cycles, so would die after a 5-year lifespan.
If your battery is losing extra range fast or drains too quickly, and both the charger and battery are working fine then it could well be down to the BMS system of the bike.
Replacing the BMS inside of your battery can be done but it should only be attempted by a professional.
What does BMS stand for on e-bike batteries?
The BMS on the battery of your electric bike refers to the battery management system. This is one of the most essential parts of the battery and ensures the top performance of your electric bike.
Its purpose is to stop the battery from overheating or overcharging, keeping its cells healthy and ensuring a consistent level of power output to your bike when in use.
Do assistance levels affect battery usage?
Yes, using your electric bike on a higher PAS level will draw more power from the battery as you are using more power/assistance from the motor on the bike too.
What kind of battery should a high-quality commuter bike have?
For a commuter bike, you need a battery with a fairly generous range yet lightweight if you want to keep it portable. 46V and 36V batteries are great for this purpose and should be mounted in the downtube or integrated into your bike's frame.
How much are battery packs sold for?
This depends, you can buy singular battery packs on your own or as part of a conversion kit. For a single battery pack, you are looking at spending around £300 depending on the quality and capacity, the large the capacity the more expensive the battery will be.
What are conversion kits?
E-bike conversion kits come with all the components a standard e-bike has ready to fit a regular bike to convert it. This will include all the essentials such as the motor, brakes, battery and cables for you to install.
Can I fit a new battery on my electric bike myself?
Yes, electric bike batteries are pretty simple to fit as long as you have all the cables and tools to remove the last one.
Do the motor and battery power have to be matched on an e-bike?
Ideally, your battery has to have enough V and amps to be able to support your e-bikes motor performance and keep it powered.
How do I keep my electric bikes battery in good condition?
Always make sure it is charged regularly, never leave it to die, keep it out of extreme temperatures, never overcharge it.
You can invest in extra tools such as trickle chargers and light alarms to make sure you keep your battery in the best condition.
What is a dual battery system?
A dual battery system means there are two batteries located on the electric bike rather than one, doubling your range, although this does add extra weight to your bike they are a perfect system for long-range e-bikers.
How do I make my battery last longer when riding?
To make your range extended when riding your electric bike you need to make sure you avoid hills, using it on a low assistance mode or none at all and never using the throttle or boost mode as this drains power fast.
Our number one electric bike battery pack is the Bafang BBS01B 36V 250W Mid Drive Electric Bike thanks to its long lifespan and top-notch BMS system which allows your electric bike to have high performance.
