I will be building a similar battery charging system for my next one whenever that is. Do you have pics or care to share details? Would you charge the panel during the day? June lots of sun I would think …in places anyway. Did you check amps as you were to get a sense of a charge rate or recovery rate? Like 18 amps when you started in the am and 20 when you got to camp six hours later. If we get bombarded by the electronics haters happy to go off list.
I was recommended to look at electric wheelchair batteries for my system due to their deep draw down without damage capabilities in case you had to run it all the way. Simple enough to avoid with a meter. Never thought to take one before.
Check out this thread:
Battery only gopro/camera charging
I built a system that fits in a 1300 pelican box. A lot of info for building this came from the thread above and the info from a fellow buzzard. I originally had an inverter and a 4 port USB hub with it but have since dropped that. I now just have a CLA splitter with two, two USB CLA plugs. Almost everything I charge has a USB connection. The only exception is my DSLR and I rarely take that.
The first picture is the system with the inverter in action. The second is just everything in the pelican box.
