......I use two 7.4v 3800 NiMH packs, which actually fit in the Hobbico 12v "base" they provide for their whimpy battery.
The whole assembly looks clean and with a normal starter I can turn over a 50CC engine with ease... along with my 1.20's 1.80's, etc.
Can you tell me more about the packs you use? Are they sub-c?
