Special Designed for 58.4V (3.2*16s)51.2V LiFePO4 Battery -- This 58.4V 5 Amp charger is designed for 48V(51.2V) LiFePO4 battery, it enables more than 90% high charging efficiency for lithium iron phosphate battery charging. It maximizes optimizes the lithium battery performance, and extends the battery lifetime to a large extent. High Charging Efficiency--The single-channel voltage is up to 58.4V, with a maximum current of 5 Amp. it can charge a 48V 30Ah LiFePO4 battery to 50% in 3 hours, 2 times faster than an ordinary 2.5A battery charger.Suitable for 48V(51.2V) 20-50ah lithium iron phosphate batteries LED Indicator and Durable Shell--The battery charger with two LED indicator is easier to monitor the battery charging status(---Power indicator light :Red light;----Charging :Red light,Full:Green light).The sturdy shell can effectively protect the charger, the flame-retardant material effectively protects safety, and the powerful cooling fan effectively reduces the temperature inside the charger Multiple security protections --- Overcharge protection, Overvoltage protection, Short circuit protection, Temperature protection, Overcurrent protection Attention-- This is a dedicated charger for 48v (51.2v-3.2*16s )lifepo4 lithium battery and cannot be used to charge lead-acid or other batteries. Disconnect the power supply before connecting or disconnecting the battery charger from the battery. The anode of the charger is connected to the anode of the LiFePO4 battery, and the cathode of the charger is connected to the cathode of the LiFePO4 battery. (The red charging clip/wire is anode(+) and the black charging clip/wire is cathode(-).)
