[QUOTE="oexing, post: 179392, member: 1493"] Now that is serious money for electric start accus. Sorry I was wrong about cell voltage of two different types of Lithium cells: The good mannered type is LiFePo4 with 3.2 V per cell The explosive type is LiIon and 3.7 V per cell. I certainly want the first type in my bikes at 3.2 V, so two of them - or 4 when parallel wired for more capacity - can be charged by standard dynamos/generators that are correctly set for 7 V resp. 14 V in 12 V systems. The LiIOn will be too high in serial wiring with added voltage so will not get charged up to specification. So far I hope for no need for electric kickstart leg and just have some low price cells soldered up in gutted battery cases.
