Battery Equalizer 24V - 2 x 12V Battery Voltage Balancer for Gel Flood AGM Lead Acid Lithium Battery with LED Display Battery Voltage(HC01 Balancer)

My batteries were not keeping the same voltage and draining or bms turning off. One would always have a much lower voltage. Now they stay equalized. And maintain a higher voltage over night. I'm happy 😊.

It does not balance two lithium battery

Its connected. I dont see that it is doing anything. My batteries may be too large for it.

It did exactly what it was designed for. At up to 5 amp balancing it’s quick too, keeping up with the 20a charge current with ease.

I installed this equalizer and for one it did not equalized the batteries within the 20 mV advertised. the difference was in volts. After two days of operation it failed completely. I will be returning it.

I connected this first, to two 12 volt batteries connected in series. At that time I measured a 1.5 volt difference between the two.After connecting the unit, in very short order the displayed voltage between the two was equalized.I then connected a 24 volt charger to the battery pair. As the charging began the displayed voltages showed a greater differential, reflecting the charging voltages I have become accustomed to with these two particular batteries.As the batteries came up to charge, the differential between the two was less than .2 volts per the readout.In the past, when charging these batteries individually, they always had different final voltages in the range of 2 volts. Also noteworthy was that the final voltage value of the pair reflects the higher voltage value that I ever achieved with the stronger of the two batteries.These two batteries were deep cycle marine type, lead/acidIn a review someone mentioned the gauge of the leads of the unit being small. I do not believe this is a factor, these are control circuts and do not see the battery amperage. All wiring in the complete set up stayed cool and showed no indication of the slightest heating.The built in display is great, the only downside of the unit is that it seems only able to monitor 2 batteries in series only as it has one single lead that is slated to connect to the 1 wire connecting the 2 batteries together.

I've been using one just like this without the voltage readout for a while now on my mismatched 100ah Lifepo4 batteries (different brands and different ages) for a while now to keep the batteries in good balance. I wanted to be able to visually see at a glance where the batteries are currently and that's a worthy upgrade, I think. It does the job.

I wish Amazon would test things before they sell them, mine came hooked it up and it gets hot and i have no voltage display?? spent the extra money to get voltage display!
