I accumulated "stuff" during the winter and got things installed on the RV. I have 2 12v 100ah Lifepo4 in parallel.
Now it's time to finish polishing the turd so to speak. The plan is/was 300w on the roof and 200w on the ground with 25ft of 10ga wire. The ground panels are for when I'm parked in the shade. All the panels would be in parallel feeding a 40 amp MPPT CC. Then the thought occurred to me that I have an older working 20 amp MPPT CC that I removed from the original 200w roof set up.
First question 1 or 2 CC?. The 40 amp is a Bouge controller, the 20 amp is unknown Chinese from 8 years ago
Second question voltage settings. The 40 amp has SLA, AGM, GEL, LI and user. The 20 amp has AGM, LA and self. The 40 amp CC set on Li is a fixed 14.5v. With the user setting I can adjust bulk, absorb, float and equliz. The 20 amp CC adjustments are charge, float, equliz.
I know 0v equliz, but is 14.5v constant OK for long term battery life? With the mismatch of charge volts/setting any recommendations
