Eaaaa ! I tested these batteries and quite pleased with they're performance. The operating voltages run from 12.6 down to 8v or 2.0v per cell. You can't let them go below that or they get pissed and start loosing Capacity levels . Voltage stay good but they just would not last as long.
Question I'm asking is would your Coil and point produce a viable and safe operation of spark down to that level ? 8 Volts? I'm thinking Yes sense your using good ol Points and coil system ?
Unlike all other Lithium Chemistry batteries these are all but a Direct replacement to Lead Acid batteries. Can be recharged via regular battery charger. You just can't leave them cooking as long.
Rated 8Ah capable of delivering some 100A until drained.
Your flight times would be under a Hour ?

I'm not sure what the lowest V you can go and still get good spark. I remember reading a couple years ago of a fellow that was flying his and it got down in the 9V range before he managed to get it landed. He stated it still ran fine at 9V.
I would like enough capacity for a 2 hour flight at least. IIRC someone put a amp meter on a stock 009 system and read about 4A @ idle and draw decreasing to somewhere in the 2A range at full throttle. (Shorter time to build the field in the coil maybe?)
