There aren't many like it , cause this one is mine .
. It has seen many a battery . The first replacement I bought was similar in dimensions and capacity which was rated 7 amp 6 Vlt. I got that battery from fry's electronics for relatively cheap . Yes, 7 amp . That was a long time ago. Of course hobie has upgraded since then to a standard equipped 10 amp battery. Tbe current battery I am using is a Bioenno LIPO4 12 amp. This battery will last me all day and not slow on flow of pump,
