Recommended Posts

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.

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.

Battery stop charging voltage

27.5 V

Quote

Battery low voltage

24.5 V

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.

Float voltage

27.6 V

Absorption voltage

28.0 V
