HA01 Battery Equalizer with LED Indicator HA01 battery equalizer is an energy transfer equalizer, which can compensate the batteries in both directions. When the voltage difference between the batteries connected in series exceeds 10 mV, the battery equalizer starts to work, and the current will flow from the battery with the higher voltage to the battery with the higher voltage. Low battery, and finally make the battery balance. It can be connected to the battery connected in series for a long time, and the balance state of the battery is automatically maintained without maintenance. Application for 24V battery bank HA01 battery equalizer, 2 batteries can be used in series. Easy to install, especially suitable for 24V series battery pack.It can be applied to solar power generation system, UPS backup power supply, wind turbine, communication base station, emergency lighting system and so on. Extends battery life and no maintenance HA01 battery equalizer can be connected in parallel in the battery circuit for a long time. When the battery has voltage difference in the process of charging and discharging, the HA01 battery equalizer will automatically detect the work and achieve the voltage balance of 2 batteries. Low self-loss consumption and long service life Imported industrial-grade chips are used to reduce product loss and ensure product quality. Strict production technology is adopted in the production process, and the quality of each process is strictly controlled. Classic Design Universal 24V Battery Equalizer HA01 battery equalizer is suitable for lead-acid batteries, lithium iron phosphate batteries, nickel-cadmium or nickel-metal hydride batteries. The connection method of the battery is not limited. It can be used in series and parallel.
