I have the Votronic VCC 1212-30 connected to my 200ah LiFePO4 battery in my van.
For a month or so (since I bought my van) everything was working properly and it charged while driving.
Last couple of days it appears 'dead' (no fan working, no LED lights on.
Checking the terminals on the charger with a voltmeter volt looks fine (14.2v coming from alternator, 12.8v on the battery terminals).
Last time I checked- if connecting a 12v control signal to the D+ terminal, the charger DO wake up and seems to work... ?
Anyone have a clue why suddenly it wants a D+ signal?!
Sent an email to the company- no response in a week so far ?
One more thing- since not having a temperature sensor (so can't choose LiFePO4 charging plan #4)- what is the other best option (1/2/3, see attached pic)?
Thanks in advance!!??
