Hi everyone!! sorry for bother you with this old issue, but i noted that you guys knows a lot about this...i want to upgrade the battery and after reading a lot ...still not sure if my solution it will work....: i would use 4 x High Capacity 20000mAh 4S 12C Lipo Pack.... my questions are: 1.- are they power enough? (i ask, because you explained in other thread that maybe dont release the spected power for a 20r oset) 2.- I 've read a lot about built in BMS...this packs doesnt have built in BMS ....it enough with the charger have some kind of BMS ? (for balance charge, voltage protect etc) or you recomend buy something else for battery monitoring? 3.- The electronic panel of the bike (if the bike would have one) supports that upgrade ? assuming that im gonna connect this packs almost the same way like the old lead acid batteries....i have an rc expert friend who will make the serial connection of the packs before i connect to the bike....he will do something like this tutorial.... well...thats all...thanks ALOT!!
