Does anyone know roughly how long it should take to balance charge a 20S 12P battery pack after the charger light turns green? Batteries are Sanyo 18650GA, charger is Luna 72 volt 150amp and the BMS is SuPower Battery (batterysupports.com) 20S 150amp.
I just replaced the first cell group and after installation it is out by approximately 0.2 volts. My pack charges to 80.4 volts, the charger light goes green and the charger stops. Last time, after charger light turned green, I left it on 3-4 hours and the voltage of my battery stayed the same. I'm thinking more time to balance but I have no idea.
