Battery (consumption)

Welcome the next generation of boat batteries, Undine’s powerful, cobalt-free lithium batteries. 

Thanks to the advanced technology, they last 4 times longer and have 5 times more energy than traditional lead-acid batteries on the market.

With batteries from Undine, you have enough power on board to keep your appliances on for days. You can safely have the light on, keep the food and drinks cold in the fridge, charge your phone and use the navigation at the same time.
