I’m almost finished with my RV-10 build and I’d like use my trickle charger
for both batteries on the ground. I’ve been maintaining both batteries
during the build with an Odyssey battery charger and both batteries wired in
My electrical system is designed with dual batteries, each having an Independent system with separate battery contactors and a crossfeed relay.
I’m thinking that I can leave the batteries wired in parallel and install a
battery disconnect switch between the + to each battery. This would enable me to disconnect the parallel circuit after charging for flight. Worst case, I
Forget to disconnect them and they run parallel in flight.
Would an ACR automatic charging relay work better? Or split the + on the charger to go to each battery.
Your comments are appreciated.
It's not real clear as to your proposed
architecture. Can you sketch it out, scan
or photograph and attach it?
Do you have dual alternators? Can you
enlighten us as to the failure modes
mitigated by this architecture?
