How to connect the voltage balancer
Before connecting the voltage corrector, make sure that the batteries are fully charged, of the same type, and with identical capacity . The voltage difference between them should not exceed 0.2V. It is also extremely important that the batteries are correctly connected in series, and the total voltage of the system is around 48V. Connecting the balancer is simple - just connect the black wire to the negative, the red to the positive of the entire 48V set, and the white to the point between the batteries – the balancer will take care of the rest. The device will start automatically, and the LED A and B will inform you that the system is working and taking care of your batteries .
For campers, on yachts, for photovoltaics - Compatible with AGM, GEL, LiFePO4, NCM, and LTO batteries
The 48V voltage balancer is an excellent choice wherever you use connected 12V batteries in series. It works perfectly in campers, caravans, boats, solar systems, electric vehicles, forklifts, and emergency power installations . It easily cooperates with lead-acid batteries (AGM, GEL), as well as with lithium ones, such as LiFePO4, NCM, or LTO . This small device can significantly extend the lifespan of the entire battery and prevent costly failures.
