I decide to make battery from laptop batteries. Battery type is 18650, in this case i use 30 cells, 6 batteries in serial and 5 in parallel. ESC Controller that i have it can handle 6S battery. Right now i don't have BMS for this battery, so i will use Pedaless to read voltage, so if drop bellow X voltage i will STOP motor to protect battery. For charge i ordered IMAX B6AC charger.
