* overvoltage. [[electrical:12v:lifepo4_batteries_thread|13.8v is a safe upper limit]] and will charge the bank completely. Some experienced folk use slightly higher voltages for faster charging but it must be terminated quickly as the bank approaches 100% state of charge. | * overvoltage. [[electrical:12v:lifepo4_batteries_thread|13.8v is a safe upper limit]] without BMS and will charge the bank completely. Some experienced folk use slightly higher voltages for faster charging but it must be terminated quickly as the bank approaches 100% state of charge. Exception: Lithium banks with BMS typically overcharge intentionally to balance cells. The overcharge is consumed by resistors and does not actually go into the cell. |
* long periods of 100% state of charge; cease all charging at 100% and only charge that high if you know some loads will be applied immediately. Lithium chemistries do not care about partial state of charge so use that to your advantage. | * long periods of 100% state of charge; cease all charging at 100% and only charge that high if you know some loads will be applied immediately.
