I am having a 100 AHr auxillary battery installed in the engine bay and I also occasionally tow a caravan with 400A Hr of AGMs mostly kept charged by 4 solar panels.
My auto electrician has suggested a BCDC1240 to charge the auxillary battery so that it can also help top up the caravan batteries when needed.
My question is: If driving without the caravan (i.e. most of the time) will this 40 Amp BCDC40D overcharge the 100 A/Hr auxillary battery
