Solar for kayak - Kayak Fishing Adventures on Big Water’s Edge

Here battery voltage versus current with a Hobie 12v bait tank pump, tank full of water:

12V --> 1.37A
11V --> 1.20A
10V --> 1.06A
9V --> 0.91A
8V --> 0.77A
7V --> 0.64A
6V --> 0.52A
5V --> 0.39A

On six volts, the pumps draws less current (so it uses less power) than at twelve volts. My experience has been a 6 volt battery last much longer that a 12 volt battery powering the pump.
