The 36v lithium battery charger has an upgraded 43.8Volt 20Amp 1200W output, The lithium battery charger 36v is compatible with EZGO, Club Car, Yamaha Golf Cart. The O-Type Terminal-M8 charging for 16 strings LiFePO4 golf carts. The automatic 48v lithlium golf cart charger adopts advanced 3-stage smart charging technology, which can automatically adjust the charging voltage and current. After fully charging, golf cart charger automatically stops output and enters trickle charging mode, which will not overcharge the battery and effectively prolong the cart battery life. This golf cart battery charger is specially equipped with a cooling fan to effectively cool the battery charger and make it work smoothly. The 36 volt lithium battery charger has a circuit protection device that provides over-voltage and over-current protection. There is no output when the battery is not connected. If the battery is reversed and the output is short-circuited, the internal circuit of the 36v golf cart charger will be disconnected from the battery and will not damage the club car 36v charger. If the ambient temperature is too high, golf lithium battery charger will automatically shut down and resume charging when the temperature recovers. Intelligent protection: 1.input low voltage and overvoltage protection 2.charger overheating protection 3.output no load protection 4.output short circuit / reverse connection protection 5.output overcurrent / overvoltage protection 6.automatic shutdown when fully charged LED status display: Wide operating temperature range(- 22 - 104℉) to adapt to various working environments. The golf cart battery charger has a special temperature sensor that can adjust the charging voltage according to the ambient temperature to achieve the best charging effect.
