I agree. However, is it possible is isolate serial transmission through optos (or equivalent)? Arduino boards will have to be isolated to avoid voltage potential differences (at different parts of the pack's series string) from wrecking stuff. Since serial comm goes both ways down a wire, a simple opto is no good there. My PWM comm should work through an opto because one wire goes from Master to Slave and the other from Slave to Master, never changing directions.

There must be another type of IC that does two way isolation.
