RE: TWO A123's directly into Batshare into Receiver no problem?
Nope... the batt share has dual batt inputs and dual rx outputs....
The above scenario is exactly why I run the batt share....to isolate a short somewhere in the system....any other type of failure is handled by having 2 batts, 2 switches, into 2 rx ports....
Vin, not sure about the JR/Spectrum stuff, but u do indeed have a common link to each batt via the rx....
FYI, the $800 Powerbox Royal and SmartFly power expanders do not break the common ground either....isolate a bad batt, yes. One batt must still be disconnected to charg 2 at a time.
