UPDATE/CORRECTION

Just talked to Andy a while ago, he says his or none of the charge switches he knows of open the ground wire... He said the problem is the Signal wire going from the switch to the RX... It will be carring 3.3v+ to the reciever and confuse the whole circuit when charging 2 battery's at the same time. Cut the signal lead and problem solved. ( No DSC capibility though ) . I'm gonna also get his "Backer" device which his is version of the BattShare. It is deigned specifically for the 123Nano Batts. The "Backer" is designed to go between your 2 switches and the Rx. 2 Inputs and 1 Output. I told him I was useing JR1221 Rx which has 2 Batt input slots. He also has the "Backer" with 2 in and 2 out leads. Another tidbit of info, He also said that the 1221 Rx has circuit built in the Rx between the 2 Batt inputs that Isolate and control input from the Batt''s. I would assume the 1222 would also have this also.

I hope this is all the info I need !!!!!
