Whether you’re shopping for a turn-key commercially available electric bike, or trying to find or build a good battery for an electric bike conversion, being able to find the right battery for an electric bike is a difficult task. The right battery pack is the most difficult part of the electric bike equation. Keep in mind that even if you’re buying a turn-key electric bike, the lithium battery is more than likely the most expensive component in it, and…not all lithium batteries are created equal, so you should know what you are getting before you buy the electric bike.Lithium electric bike batteries are not cheap, they are not perfect, and they are not readily available. It is surprisingly difficult to find a ready to plug in Lithium battery pack for sale on the internet by any real company. The reason is simply product liability.Lithium Battery technology in a electric bike is still experimental and you have to use a lot of common sense when using these batteries. However with a little education and some end user carefulness, you can use lithium batteries safely.Lithium batteries are currently the “hottest” battery choice for electric bike enthusiasts. Lithium batteries are the most power-dense type of battery available to electric bike riders today. The problem is that LiPo battery packs for e-bikes are hard to find, especially one with high output if you are building a racing bike for riding off road.If you want a lithium battery pack, one of your better choices if you want to save money and have a lot of output amps is build one of your own from a Hobby King packs. This requires a lot of time and knowledge, not only in building the pack but also in managing it. lithium batteries can be extremely dangerous and prone to burst into fire if not assembled with a lot
of precautions (BMS) and cared for properly.Essential for either building or buying a ready made pack is deciding how large of pack
you want and how much you are willing to spend on that pack in terms of weight and price.Most of the price involved these days in building an electric bike or buying a ready to go electric bike is the size and chemistry of the battery pack. For the consumer its important to understand the difference between a 24V, 36V, and 48V pack. Also know what a 10Ah pack is compared to a 5Ah pack.36V 10Ah pack contains 360 watt hours. Approximate range on average riding conditions 30 -40KM.
48V 10Ah pack contains 480 watt hours. Approximate range is 50KM.
48V 20Ah pack contains 960 watt hours and once you get close to 1000 watt hours you are
getting serious commuting range which most electric bike manufacturers promise but do not deliver…When you are comparing packs of different voltages calculate watt hours to see how much you are getting for your money…especially when buying a turn-key electric bike. You are not biking far without a good electric bike battery. There are many types on the market today. Read on to make sure you get the right one. Read a little more for care and maintenance tips.
There are two basic batteries in use today: Lead-Acid (Pb-A) and Lithium-Ion (Li-Ion). Nickel Metal Hydride, Nickel Cadmium and a few other chemistries are used to a lesser degree.
Lithium batteries widely used in the field of electric bike,because lighter and longer lived than PB-A batteries.
