3W Ignition Module Voltage
Can a 3W-150 ignition module, marked 4.8 volts, be used with A123 cells at 6.6 volts? I think I have read somewhere that 4.8 volts is the minimum voltage and it is safe to run them up to about 8 volts without a regulator. I know the use of regulators is not recommended on 3W ignitions.

RE: 3W Ignition Module Voltage
It all depends on which ignition you have. If it is the newest version, then it can be run on a higher voltage. If it is the older versions, they come in 2 voltages which is 4.8 or the ones marked 4.8 with a blue dot. The blue dot older ignition will tolerate a fully charged 5 cell nicad or Nimh which is around 6.8 volts but the voltage drops fast when the battery is used.
The way to tell is to look at the engine. If you have one magnet on the hub and a large size sensor, you have the older ignitions. If you have 2 magnets on the hub and a small sensor, you have the new version of ignition.
Hope this helps
