Hi, for a very minimalistic setup, I've ordered the following panel off Amazon:
I'd like to use it for camping and for maintaining my car's AGM starter battery when not using the car for weeks. My car has some parasitic loads and if I don't use it for 4 weeks it goes under 12.0V.
The reason I choose this panel was that it has a built-in regulated 14.4V output, allowing me to directly charge the car's battery, without any electronics involved. At least this is what the description says.
My question is: do you know if it's safe to keep this one plugged in for weeks inside the car? Or should I buy an external solar charge controller for this purpose? My car's battery goes down about 0.02 V per day, so I don't care about efficiency, I'm just looking for something which can safely maintain it.
