I have a Multiplus 24/3000/70-16 and a BMV702 set up in an RV with two separate battery banks (house + starter).
I noticed today that the AC input had failed, and the Multiplus depleted the house battery bank before entering low voltage shutdown at 24v (full charge is 28.7 volts). However, when I check the BMV702, the starter battery is also showing depleted at around 25 volts.
In VRM, I can see that the trends for both batteries follow eachother, which indicates to me that they are being paralleled for some reason.
Is the trickle charge connection (or the BMV702) somehow parallelling the battery banks??
