I have two AGM battery banks with existing BMV702 monitors (no temp sense installed). The banks are in the engine room of my boat.
I am installing an MPPT 100/30 on each bank and am a little concerned with voltage and temp compensation. The controllers will not likely be in the engine room, and will be about 10' away from the batteries.
Am I best to install a battery sense on each bank, or am I able to get the bluetooth dongle and temp cable for the BMV702's and use that somehow ?
or, am I overthinking things. The batteries never get over 35 C, that is only 0.12v of compensation needed which should not be a problem if I set the voltage parameters in the middle of the band for my batteries.
