Review on 🔋 5A 3S 12V 12.6V Battery Active Equalizer BMS Balancer LFP Lifepo4 Lithium Lipo Li-ion Battery Energy Transfer Board by Chris Moody

I'm having trouble properly balancing a custom 140Ah 4S LiFePO4 battery. I decided to try this and am very glad I did. Of all the solutions I tried, this finally achieved the perfect max balance with all cells at 3.6500 +/- 0.005. It balances at a higher current than most others I've used, so it's particularly good for larger setups. It didn't get hot during use, not even lukewarm, which is another big plus considering it's in a warm indoor environment. It ran all day on a few amps at 90F and wasn't even slightly warm. As an added bonus, it has pads to which you can solder a switch to turn the scale on and off remotely. I use this to turn off balancing when the battery isn't in use, but can turn it on while charging. If you want to get creative, you can even hook up a simple relay so it automatically turns on when charging and off when idle. In sleep mode, the background current draw seems minimal, but I wouldn't leave it plugged in if I'm storing the battery for a couple of weeks. All around a fantastic device.
