In the user manual, we can see that input voltage is 4 to 9v.
It is said also to use 2 cell LiFe or 2 cell LiPo.
Is there a voltage rise inside the sparkswitch to have an output at 12v ?
I would like to know if I can use 3S LiPo ?
Another question : can I charge my ignition battery still plugged on the sparkswitch (charge wires in parallel with the power wires) ?
