Default RE: Ceramic Igniter and ECU battery

Eric,

I have a similar experience. I was going to call you to discuss. The new ceramic igniter does work very well. My rabbit instantaneously ignites! But I was getting low battery msgs after a couple starts. Pack was fully charged - I was using the included 7.4V duralite pack.

I ended up putting a wattmeter on the battery since I kept getting the msgs. It turns out at a plug setting of 200 I am pulling 18 amps of current! At 225 I was pulling 19A. So not a lot of difference going up, but the base current draw for the ceramic igniter seems huge. The duralite li-ions just cant handle that. They are rated for 10A max and then their internal switch is most likely kicking in to save the batteries.

Anyway, I ended up using a 2s lipoly pack since it can handle these types of current draws. No problems after that...
