Easy to install

Our batteries can be easily installed in parallel to easily increase your battery capacity and have a pack fit for any boat.

The Green Marine Battery is designed for use in high-demanding boating and versatile enough for the various kind of leisure boats.

Battery type

We work with lithium iron phosphate (LiFePO4) due to its high energy density, long lifetime and increased safety in comparison to other lithium battery technologies. Additionally, LiFePO4 does not contain cobalt.

Battery capacity

The GM batteries have a standard capacity of 100 Ah and are available in a 51.2V (16s) option or a 57.6 (18s) option. The packs can be connected in parallel to obtain higher capacities for a broad range of boating needs.

The Green Marine battery allows for a whooping 2.5C discharge rate. Maximum charge rates are 1C in order to be able to fully charge the battery in one hour. To optimize durability it is advised for all LiFePO4 batteries to do regular charging at a maximum rate of 0.5C. Combine your battery with a GM charger for the best charging performance.

Due to the battery technology and design the battery has a cycle life of 3000 cycles at 80% depth-of-discharge. The integrated BMS monitors the battery state-of-health and balances individual cells to increase durability.
