Hello, I have a 5 years old used car battery of 70 Ah and 4 solar panels connected in parallel giving 8A aprox. and today my charge controller (CC) is set to 13,8V max to charge, I want to change this setting to achieve maximun solar charge in winter (right now it's spring here), I think 14,8V should be a good value but maybe higher is better. My CC is the cheap chinese blue one from ebay. Any advice?
Thanks in advance.
