Hello everyone,
I am wondering just how to setup the battery charger for the electronic ignition battery. Do I connect battery to charger, then charger to ignition? Will charging the battery effect the ignition? What is the correct battery for the ignition? The engine I've installed is the Fuji 50EI. Thanks in advance for any help.

I have the same engine. you can use a 1100 to 1600 ma 4 cell nicad or NeMih pack depending on how much you fly on a given day. I use a switch with the charge jack built in. Just hook the battery to the switch and charge as usual. you connect the output side of the switch to the electronic module. Make sure you do not turn the engine over with the power on with out the plug wire connected to the spark plug, and the plug 's shell connected to ground on the engine. If not you can damage the module.

Carver, most ignitions we use for gassers require a 4.8 volt battery set up or 6 volt with a regulator.
If you have set up your system with a manual on/off switch with a built in charging jack then when you plug in the charger it will automatically
isolate the ignition side of things so only the battery is getting any charge.
Charge the battery at a rate of 1C being 1/10 of the batteries capacity. ie; 1800Mah pack charge at 1.8amps for 16 or so hours for full charge.
If you have a fast charger then you can top up at the field. Just read instructions.
Have a look over at the giant scale forum and have a good read Mate. A wealth of knowledge there.

AA or sub C size does not matter apart from size and weight restrictions for you model. I use a 2500 NicMH AA pack in my 27% Extra/ZDZ80 twin and get 4 flights and then charge all batteries up.
