Charging without a Charge controller
I have a need to connect, short term, a PV or 2 to my camper battery. We are demolishing our old cabin and using the camper for sleeping in, a bit of cooking and showers etc... both my CC's are still in use and I don't want to buy another one for this temporary setup.
Is there a rule of thumb to use for this hookup?
~ 660 amp battery, 25 W and 70 watt panels available. not direct sun as in the shade.
