Simple Guidelines when Repairing Battery Packs.
- Only connect cells that are matched. Do not mix cells of different chemistry, age or capacity.
- Never charge or discharge Li-ion batteries unattended without a working protection circuit. Each cell must be monitored individually with a protection ...
- Include a temperature sensor that disrupts the current should the pack get hot.
- Apply a slow charge to a repaired pack to bring all cells to parity.
- Pay attention when using an unknown cell brand. Elevated temperature hints to an anomaly.
- Do not charge a Li-ion battery that has physical damage, has bulged or has dwelled at a voltage of less than 1.5V/cell for some time.
