Lithium battery conversion checks before you buy

Lithium can give you more usable capacity for less weight. A safe switch is a charging system job, so do not assume it drops right in.

Lithium conversion

LiFePO₄ means lithium iron phosphate. Check the converter, alternator, solar, BMS, temperature, wiring, voltage and physical fit before you switch.

Five things to check

Review the converter, the alternator charging, the solar controller, the BMS and how it acts in the cold, all together.

  • Lithium charge setting
  • DC to DC charger or alternator current control
  • Solar controller settings
  • BMS steady and surge rating
  • Protection from charging in the cold

Compare usable energy, not the amp hours on the label

Usable depth of discharge is how far you can drain the battery. Take that number and the cycle data from the chosen maker's current documents.

  • Use the exact datasheets
  • Count the charger cost
  • Count the warranty terms
  • Check the physical size

Advanced options

Plan around how you use the battery

Use this when you know your system voltage, daily energy use, cart setup or accessory load.

No login needed
For modest RV use, start with 800 to 1,500Wh a day. Then adjust it from your real loads.
