Solar for kayak

I have a 6 volt 10 amp battery and run a 500 gph bait pump continuously while I am out and I did 3 5-7 hour trips and it was still pumping as if it were fully charged. If you use math and stuff you should figure out that when you use a pump rated for 12 volt on a 6 volt system, it will draw twice the current. Which means a 6 volt 10 amp battery would last half as long as a 12 volt 10 amp battery. The guys at the battery shop agreed with my theory and the practice of taking it out a couple times backed it up, too. So, in other words, you should be good with that battery. If you are really worried about it, get a timer for your bait pump and turn your GPS/fish finder off when you are not using them. I agree with the other guys who posted and think it would be easier to put a backup battery in. This would probably help fight against battery memory and make your batteries have a longer life because you could fully discharge your battery and switch over to the full battery, then fully charge the dead one after the trip. This would ensure that you aren't just charging your batteries halfway up every time you go out.
