Best lithium RV batteries – Editors’ choice

Best for small budgets

Best all around

Best for comfortable off-grid RV experience

How to choose the correct lithium RV battery?

First of all, to choose the correct lithium RV battery we have to take into account the specificity of energy use in your RV.

Usually, batteries in RVs are charged by solar panels through a solar charge controller. Due to limited available space, the solar panel arrays total power rarely exceeds 800W. Therefore, a complementary charging source could be the vehicle’s alternator.

In addition, lithium RV batteries must retain their state of charge after long periods of inactivity. It is indeed true that most RVs are used during the weekend or at maximum, month-long vacations.

Lead-acid batteries are still commonly used by RV owners. However, they suffer from a heavy weight and low durability. Luckily, lithium batteries are solving these problems.

In this article we have selected lithium RV batteries that are:

  • Compact
  • Lightweight
  • High capacity
  • Powerful
  • Maintenance-free
  • Long storage life
  • Durable

Our broad selection ranges from lithium batteries for budget systems (lower capacity) to massive storage capacities to power any household appliances when connected to a DC-AC inverter.
