Lipo batteries are currently the “hottest” battery choice for electric bike enthusiasts. LiPo 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 LiPo 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 pack. This requires a lot of time and knowledge, not only in building the pack but also in managing it. LiPo 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 e-bike or buying a ready to go e-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 10-Ah pack is compared to a 5-Ah pack.
A 36 volt 1o-Ah pack contains 360 watt hours. Approximate range on average riding conditions 12 miles
A 48 volt 10-Ah pack contains 480 watt hours. Approximate range is 15 miles
A 48 volt 20-Ah pack contains 960 watt hours and once you get close to 1000 watt hours you are getting serious commuting range which most e-bike manufacturers promise but do not deliver…think 30 miles.
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 e-bike.
