RE: Dual A123 battey though diode voltage drop?
Captain, I have tested the dual battery device and has dual input cables, two diodes and two output cables. It will power by both of the output cables with only one of the batteries, so its redundant.
After all, I have listened to your recommendation and removed the dual battery device, now voltmagic works as expected and the average and peak low voltage remain in a safe spot.
Thank you.
