Consumption battery (Powerbox Large)

100+ hours of active use at normal power consumption or approx. 4 days in a larger sailboat (4 amps).

Our batteries are specially developed for boats that spend many hours at sea in changing weather, large temperature differences and they are optimized to handle the challenge of salt water. They can be charged via hydrogenation, solar/wind energy, diesel generator and from shore power through an ordinary battery charger.

Please write in the comment field if you need help with installation.

Payment is made upon delivery/pick-up.

For limiting and optimizing the charging of the Undine PowerBox from the generator on the boat engine. Lowering to 40A to reduce wear and avoid overheating of the alternator on the engine.
