Enerdrive

The safe specification on a boat you live on. You pay a premium for the dealer network and the documentation, and on a large house bank that premium is the point.

Best for

Liveaboards and full house banks where support and certification matter more than price.

Look elsewhere if

The boat is a weekender on a trailer and the bank is 100 Ah.

KickAss

Strong value per amp-hour and easy to buy on a Thursday for a Saturday trip. Specified for touring first, which makes the enclosure and the marine duty your problem.

Best for

Weekender trailer boats and small house banks on a budget.

Look elsewhere if

The boat is surveyed, insured on a specified install, or lives in salt water full time.

Both brands are re-checked each quarter. Where a row says claimed, we are repeating the manufacturer’s figure and have not measured it ourselves.

Take the load estimate, charging sources and cable runs to a qualified marine electrician. Our installation guide helps you ask about isolation, over-current protection, ventilation and compliance before work begins.
