to use as a power source off-the-grid on a fishing trip where there will be no power available for a week. I hope to use the panel to charge the battery all day and use the battery to charge up my GPS, walkie talkie radios and laptop in the evenings. The 15v peak power produced by the solar panel (trickle charge) appears compatible with the 13.5-15v charging voltage (testing it has ranged from 6 to 15v at any given time). To invert the power I’m using a Black & Decker 400w inverter with two outlets and a USB connection. How well should this setup work, and is there a risk of overcharging the battery? The Enercell battery is from Radio Shack.
I’m not electronics savvy so I would need to go with parts and things that are available as off-the-shelf products like you could get from Radio Shack.
As it sits right now the battery shows a charge of 12.0v, and (blinking) 30 DC mA (don’t know if I have it set correctly but I have one dial set to DC mA and the other dial turned to 30 m^/10A to test amps)
