This is for shore power charging two Li Time 12V 100AH batteries wired in parallel in my RV.
I'm trying to determine if I should upgrade my WFCO 9855 charger to a lithium compatible unit. My WFCO initially charges at 13.6V. I don't know if it folds back after bulk charging is done.
I'm considering purchasing a fixed voltage capable charger such as the Powermax PM3 55LK. I note in a thread on this forum that there was some comments indicating set-and-forget charging at 14.4V is not advised.
I assumed that in order to reach full SOC, that 14.4V is required. I also assumed that trusting the BMS to do it's job was ok... attach 14.4V forever and be on my merry way. I'm at a little bit of a loss understanding why this is not advisable. If the BMS doesn't stop charging when complete at 14.4V, how is using 13.9V better for the system? Again.. shouldnt the BMS hand this?
Can someone provide guidance for me?
Thanks!
