How to choose the correct lithium RV battery

To choose the correct lithium RV battery, you must consider the energy use specificity in your RV.

Usually, batteries in RVs receive charging by solar panels through a solar charge controller

Due to limited space, the solar panel array’s 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. 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 being overly heavy and low in durability. Luckily, lithium batteries are solving these problems.

The lithium RV batteries we included in this article are: 

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

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