A 123 Wiring Configurations   

For various setups.  Note diodes in circuits where ignitions are voltage-limited in specification, to prevent violating warranty.

Both setups above utilizing MPI "Heavy Duty" charge switches, so that the FMA Cell Pro 4S with a "JR" node connector can be used through the charging receptacle in the switch.

This diagram shows a 2S A123, 1100mah, "Black and Decker" VPX setup powering the ignition module and a smoke pump.  Works just dandy.

 

This diagram shows how I have a two-switch configuration setup on my JR/Spektrum 2.4 Ghz DSM setups.  *** I HAVE NOT TESTED THESE ON "normal" 72 Mhz RADIOS ****

 

 

Diagram below is final configuration with a little more detail on the 2S A123 setup, two switches, and diodes in line for reducing voltage to the ignition module.
