   * 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.

+    * IF you're storing the van or know you're not going to be using the batteries for more than a couple days, it's strongly recommended to leave lithium batteries at 50-80% SOC. Lithium chemistries do not care about partial state of charge, and actually prefer it..
