Question:

I heard you can use this on-board battery charger to charge three seperate batteries even though they are connected in parrallel. Is that true, and if so how does the charger monitor each inidivdual battery if they are all connected? Thanks

The NOCO GENPRO On-Board Battery Charger # NOC74FR can charge up to 3 different battery banks. It cannot connect to different batteries in a parallel or series bank of batteries.

By connecting to one of the batteries in your parallel bank it will charge all of the batteries at once. If you had it connected to multiple batteries in the same bank it will not charge correctly as it will misinterpret the charge it sees as battery voltage.
