Fished with my new Dakota lithium ion 10ah battery on a humminbird helix 7 for 7 hrs and it never came off 100% charge! Not to mention my whole unit with the new battery is lighter than just the old battery. Love it

I modifed this to put a standard 12v socket on it, and it works just fine.

Easy to replace the clips with an aviation connector

Two hours and fully charged my battery

Surprised how fast it charge

Satisfied

Nice product.

Thank you for Great service !

Very easy to use, just wish it had some other options for connection.
