Rolls suggests 5 A per 100 AH of battery capacity
The Mex trick of adding a 12v light inline, like a 60w, I thought was to maintain the current while eq, I thought it was along the concept of the current is the same in the circuit and the bulb would force 3-4 amps in the circuit. Bologna?
Also the reasoning for min 100w solar or 5A per 100ah cap. ?
Goofy reg volt controll in chevy Colorado, I use manual charger that reaches 15.3 overnight on occasion, sealed. Other times I use a 60w PV and controller to hit with 14.6v on a sunny day.
