Hi All, I have this crazy idea to be able to charge my laptop/ipad/iphones inside my camper I want to buy 24- AGM deap cycle battery http://www.canadiantire.ca/en/pdp/m...p-24-agm-deep-cycle-battery-0102498p.html#srp and hook it up to YonHan 4 in 1 Charger Socket Panel, Dual USB Socket Charger 2.1A + Blue LED Voltmeter + 12V Power Outlet https://www.amazon.com/dp/B0747LK4N...4C&pd_rd_r=HN8ZBBJ4BKX4Q8KNW6SG&pd_rd_w=JRNLv The panel will go outside on the side of the wooden bench. Ideally, I will put it semi permanently under a seat compartment. Need your help please to figure out: 1) if I wire the battery permanently how will I take it out to charge? Any advice? Probably I need to install it not on a bench (on the second thought I will not be able to access the battery in closed camper postion after I come home from camping site; each time I would need to pop it up to get to the battery to charge it) i will probabley have to position it neer entrance door.) 2)How do I hook up the battery to the panel up? There are 4 wires plus and 4 wires minus and 1 ground 3) Do I need isolate each of them. Where to hook up the ground? In general is it a good idea? Any other ideas/comments please. I a rookie in camping and pllaning to camp off-grid. I am not electrician. Please help! Thank you Guys!
