[QUOTE="justnortherns, post: 234483, member: 4019"] I've run a small 12V fish finder using only AA rechargeable batteries. I grabbed a Radio Shack 10 AA battery holder (so 1.35V * 10, over 13V when fully charged) and hooked the battery holder directly to the fishfinder. I never ran the batteries down during a whole day of fishing, although I did turn off the power occasionally when the boat was stationary. Apart from the battery holder (around $2 I think) this cost me $0, since I just borrowed the high-capacity rechargeables that my kids' toys were using (they didn't mind, they were fishing as well)! Of course, to do this, the batteries should be at least over 2 Ah each and the fish finder shouldn't draw much current. If you can get a spec from the manufacturer about current draw and operating voltage, it helps to figure out how many batteries you'll need. My FF spec was 200mA max current draw and 10V to 16V operating voltage range. [/QUOTE]
