Sanyo GA 3500mah cell battery pack. 14 series 6 parallel. BMS bypassed and programmed to charge to 56.7V to prolong life of battery. Meaning BMS is only installed for charging of battery pack, power to controller is supplied directly from the pack. Full charge 56.8V No BMS for discharge means this pack can fully power any setup till 140A. Note that since BMS is bypassed, there is no low voltage current cut off and you have to monitor the voltage yourself and should stop using the battery when it hits 40V. Theoretically, the batt can go all the down to 35V but please don't as it will reduce battery lifespan. Ec5 connector. ( 1 for power, 1 for charging) Plug and play ready. Charger supplied if price is met. Cells sourced from dualtron ex+ stock battery. Not wrapped as I have no wrapping materials. This was a side project of mine.
