How to reduce amperage from an 18650 li-ion cell to 3 amp 1.2 Volts? Answered
Project is to adapt an 18650 cell to power an RC Glow plug. I just need to get the battery to power the glow plug to a working safe level.
From my multi meter I read around 5 Amps out of the battery and around 4.3 Volts when fully charged.
I have already tried a 2.7 and 3.3 Ohm resistor and its not worked. These look to have reduced the Amperage far to low.
By plugging the battery directly to the glow plug it burns the plug out.
From my understanding I need to reduce the supply down to 3 Amps and 1.2 Volts.
Anybody have a suggestions?
