Alex Posted November 19, 2020 Share Posted November 19, 2020 Hi, I build a DIY 24V 100Ah LifePO4 battery with a 60A BMS for my MUST inverter. What is the recommended charge voltages for LifePO4 batteries? See attachment please. Battery stop discharging voltage Battery stop charging voltage Battery low voltage Battery high voltage Float voltage Absorption voltage Thank you.

I would use essentially 8/15 of the values recommended for 15S Pylontechs; see below. Quote Battery stop discharging voltage 25.5 V. I'm assuming that the Must would be like 24 V Axperts, allowing these settings at 0.5 V intervals. Quote Battery stop charging voltage 27.5 V Quote Battery low voltage 24.5 V Quote Battery high voltage Axperts don't have this one. I would use at least 3.65 VPC, so 3.65 x 8 = 29.2 V. Quote Float voltage 27.6 V Quote Absorption voltage 28.0 V Alex 1 Quote Link to comment Share on other sites More sharing options...
