Batteries

We’re proud to offer EarthX’s BMS compliant light weight Aviation Lithium batteries. These batteries are designed and engineered with a completely redundant battery management system (BMS) to protect your battery from over discharge and over charge. They feature short circuit protection, and excessive cranking protection in addition to their integrated cell balancing technology.

These are the recommended batteries for operation in the back-country.
