BFL13
I do not let the cheap PWM controllers charge above 13.9 volts,if it is a good day of sunshine I have just disconnected the panel via a anderson connection but usually,I just lower the boost to 13.5 or so..
The main reason for my controller upgrade so I don't have to monitor it all the time..That's just me and my opinion on $15-$25 dollar controllers..Im sure they work just fine charging to 14.4 but I personally don't trust them to do that,unattended.:B
I have had LFP for a year now and learned a lot but there is a lot I am not sure of yet..
