Here are some figures of the A123 LiFePO4 battery cell ANR26650: Also a balancer is required which usually combined with the protection circuit. Not just the LiFePO4 technology is the key to success, but its patented method in nanotechnology. LiFePO4, like any other multi cell lithium battery needs a BMS, which protects cells from over discharge and over charge. There are more LiFePO4 manufacturers, but they differ in quality. This battery offer high charge rates of 15 minutes, which allow fast charging on the go. I prefer LiFePO4 battery cells ANR26650 from manufacturer A123. The disadvantage is the lower energy density, but note that the energy density of other lithium ion batteries degrade drastically after some years of usage. The voltage of lithium cells varies considerably during discharge and the nominal voltage is therefore stated with 3.6V or 3.7V.Ĭommonly, e-bikes use lithium ion batteries which are available in different chemistries: LiCoO2, LiNiO2, Li-NiCoMn, LiFePO4 etc. LiFePO4 batteries have some advantages: longer cycle life and fast charge capability. The latter is also lithium but has a lower cell voltage and a very long life. Batteries for e-bikes can be broadly divided into two types, lithium and LiFePO4. Common battery types for ebikesīatteries for e-bikes can be broadly divided into two types, lithium and LiFePO4. This article explains why, in order to extend battery life, you shouldn't charge to 100%: How to make a lithium battery last, or…kill it, if you like. Grin Technologies sells e-bike batteries that are allowed in aircraft luggage. There is a solution: dividing a battery into smaller packages.
