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 Wayne Laguna

I have 4 of these SLA/AGM 100Ah 12V batteries to drive. Although the batteries are paired for a 24v system I have 1 set of wires to each 12v battery. All batteries are always within 1/10 of 1 volt. I have yet to unbalance her. I stressed the system heavily over the weekend to see how the discharge and recovery would handle a significant stress. Some received a few tenths of 1 volt but were rebalanced within 2 hours. That's the coolest thing about the SLA/AGM balance. I used to disassemble my bench to level it. Now it manages to balance without batting an eyelash.
