Question:
I have a Casita with lithium batteries. Will this panel charge them properly? – Holly from Texas
asked by: Holly
Expert Reply:
Yes, Holly, it sure will. The included PWM controller in the etrailer 100w solar kit # E28VV has preset charging profiles for sealed, gel, AGM, flooded, and lithium iron phosphate LiFePO4 batteries.
When you first connect, Go to interface 11 ‘battery types selection’(page 10)by pressing ‘+’ ‘and ‘-’. • User can choose your battery type by following steps. A. Press and hold ‘+’, until interface flickers. B. Press ‘+’ and ‘-’ to find your battery type, then press and hold ‘+’ until interface stops flicker. Your battery type is selected.
