48v EV battery
Golf cart LiFePO4 48V Electric vehicle battery 100Ah with relay solution
1. Description of 48V 100Ah electric vehicle Battery
The 48V 100Ah Electric Vehicle Lithium battery pack is customized for Yamaha AC Drive Golf Cart, to replace the lead acid battery. It has much longer cycle life up to 2000times and provides more power time for the golf cart. Built with CANBus communication and relay solution, the LiFePO4 battery pack ensures the golf cart to run safely and reposefully.
