This is a heads up to owners of the DCC50S
I installed a Renogy DCC50S and bluetooth dongle in November, all was working right when I got done configuring it, setting battery type to user defined setting parameters, etc, then while monitoring things today I noticed that it was not charging from the alternator, first I check for wiring / breaker problems, then checked software, the app would show charging from the alternator, but only at about 1 amp, even though the batteries were down to about 85% charge. I eventually tried switching battery type to lithium and it went to 48.25 amps charging, switching it back to user defined battery profile it continued 48.25 amp charging. I don't know what the problem was, software glitch, or when it happened in the last couple of months (was working right in January), but changing the battery type to lithium and back to user seems to have fixed it for now.
