Review on 💡 48V Battery Equalizer - Voltage Balancer for Battery Banks with 4x12V, 8x12V, or More, Extending Battery Life by 1+ Year | Gel, Flood, AGM, Lithium Battery Compatible | HA02 Balancer (Battery Equalizer 48V) by Phil Kuebler

UPDATED: I have noticed that one of my batteries is consistently unbalanced, it seems to be off by about 0.4v without a balancer. Fortunately, the balancer now keeps them at a maximum of 0.1. Both batteries are the same, but one is a slightly newer design than the other and it could be (an old parasitic BMS design). In any case, I am satisfied with the balancer and have bought a second one to supplement it with other battery series. on the plus, white in the middle, black on the minus, it started blinking on the battery with the lowest voltage (I think the instructions say otherwise: it should blink on the battery with the highest voltage) after 12 After hours the device is still blinking and the battery voltage has drifted by almost 0.2 volts, I'm starting to think it's not working properly. When the video was taken it was connected for about 12 hours and Battery A was 13.1 volts and Battery B was 12.93 volts (Battery B was at a lower voltage and was blinking).
