How to connect a voltage balancer

Before connecting the voltage equalizer Make sure that both batteries are fully charged, have the same type and identical capacity. The voltage difference between them should not exceed 0.2V. It is also extremely important that the batteries are properly connected in series, and the total voltage of the system is about 48V. Connecting the balancer is simple - just connect the black wire to the minus, red to the plus of the entire 48V set, and white to the point between the batteries – The rest will be taken care of by the balancer. The device will start automatically and LEDs A and B will let you know that the system is working and taking care of your batteries.

Works with any 48V system - Universal application, wide compatibility

For camper, yacht, photovoltaic - Compatible with AGM, GEL, LiFePO4, NCM and LTO batteries

The 48V voltage balancer is an excellent choice wherever you use two 12V batteries connected in series. Ideal for campers, caravans, boats, solar systems, electric vehicles, forklifts and emergency power systems. No problem works with lead-acid batteries (AGM, GEL), as well as with lithium batteries, such as LiFePO4, NCM or LTO. This small device can significantly extend the life of the entire battery and prevent costly failures.
