Features Green Marine lithium boat battery.
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 (dis)charge
The Green Marine battery allows for a whooping 1.5C 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.
