That could be a significant voltage drop across the resistors. I'd use
a couple power Schottky diodes instead.

Big old power resistors. I think they were 1-2 ohms. However, after considering battery performance implications of deep discharge I normally fly with the switch set to both batteries.

... a few ohms of series resistance will cut it down to a couple of amps if you are anal about it.

Anybody who took EE101 (and most everybody else) can tell you that:
E = I * R
If
I = 1A
R = 1Ω
then
E = 1V
