Lithium vs AGM in Caravans - What You Need to Know

Lithium vs AGM in Caravans - What You Need to Know

Intro
LiFePO4 has changed off-grid touring. Here is a practical comparison with AGM so you can decide with confidence.

Why Lithium (LiFePO4) Wins For Most Travellers

  • Usable capacity - more depth of discharge without damaging the battery.
  • Fast charging - accepts higher charge rates when paired with the right chargers.
  • Lighter weight - significant saving compared with AGM for the same usable energy.
  • Long cycle life - ideal for frequent touring.


Where AGM Still Makes Sense

  • Low upfront cost for occasional use.
  • Existing systems where replacement like-for-like is simplest.


Charging Differences

  • Lithium - needs lithium profiles on DC-DC, solar MPPT and mains chargers.
  • AGM - higher absorption times, lower acceptance as it nears full.


Weight and Space

  • Lithium packs more usable energy per kilo and per cubic centimetre.


Bottom line
For most caravan setups, lithium gives more usable energy, faster charging and less weight - perfect for modern off-grid travel.
