Good to know
- Charge only with the lithium charger supplied with the kit or one the maker approves; a lead-acid charger can damage a lithium battery.
- Running lights, a radio or USB ports? Most conversions need a 12V converter; check the parts list above and see accessories.
- LiFePO4 should not be charged below freezing unless the battery is heated or has low-temperature protection.
