I am setting up a new trailer and I want to run everything on battery and need to figure out how to set up so I can charge my planes and transmitter batteries wile hanging on the wall and would like to charge 6-8 planes and 3-4 radios at the same time.</p>
the perfect scenario would have the charge wires at the back of the trailer coming out the wall by the planes and the radios in the front.</p>
I plan on using a couple 12v deep cell batteries and no110v only to charge the 12v deep cells.
I need to know what to buy what charger or chargers, Power supply, will work. Iwould like to stay under $500</p>
Any ideas on the best way to do this. Thanks!
