I've paired a Renogy 3000W Inverter Charger with 3x Renogy 100Ah Smart LiFePO4 batteries. The inverter/charger manual has this to say about the 'Lithium' charge profile:
Thanks in advance!
From what I can read, including in their own battery manual, 14.7V is quite high for LiFePO4. Quoting said battery manual:When battery voltage reaches 14.7V charging will stop. When battery voltage drops below 12.5V charging will resume.
Forgive my questions here, being a relative beginner, but is it possible that the BMS inside each battery is regulating down the voltage (and current) as necessary to charge safely at up to 14.4V as the battery manual states? Should I set up a custom charge profile on the inverter to avoid charging at too high a voltage?During standard charging, the battery is first charged at 20A constant current until the battery reaches 14.4V. Then, the battery is charged at a constant voltage of 14.4V while tapering the charging current. Charging is considered complete when the current is less than 2A. However, leaving the battery on float will continue to balance the cells and will not harm the battery.
Thanks in advance!
