Single cell vs 5 cell on board ignition pack
 

In the process of (re)setting up an on-board ignition for an inverted Magnum 4 stroke.
Since the old Fox idlebar plug gave up the ghost, it's been prone to quitting at low idle. Had an on-board glow hooked up previously for the original engine, an OS 61FX and it worked great. Will see if this fixes the Magnum problem.
Anyway, my question is: Which would be better (or would there be any difference besides weight) between a single NiMH "C" cell rated at 3000mAh and, say, five "AA" cells in paralled rated at 600 mAh each?

The "system" would be used for initial start and rigged to come on at low idle. Off above, say 1/4 throttle, if that makes a difference.
TIA, G42

The # come out the same so I'd probably go with the sub c as it would be smaller and easier to mount. Just my opinion, though..

Sub C is the better choice. To go with a 5 cell AA pack, you'd have to have one custom made, or make one yourself, since stock AA packs are series, not parallel

I've been making my own Nimh packs for years. Switching over to Life's now so have many good cells left to re-use.
I know there is a downside to a pack in that one (or more) cells could go bad.
I was originally questioning in my mind which configuration would provide more amperage, etc.
