Foil Drive Battery Checker - 40V Brand_Surf Ears Size - 40 x 70From Foil Drive Take it to the water with you to check which over your batteries has the most charge, or use it at home to see if you've reached storage level without having to run down to your shed to plug it into your kit. These are available for both the Assist and Assist PLUS and are not cross compatible. Whilst it wont hurt your battery or checker, the Assist PLUS checker wont display the correct information for an Assist battery, and vice versa.
