Hidden Battery Packs

[overdraft]

And one 2.3Ah battery was not enough @ high rpm. Especially with the lights on.

I'm confused ??? i took the battery right out of my cb350 for the hell of it and rode it around the block with no problem. it even idled with the conventionally bulbed head and tail light and all the idiot lights... sure the lights didn't burn brightly, and sure the bike stalled if you turned the turn signals on without adding a bit of throttle... but if you're a kick only surely the battery is just there to keep the electrics operational at low rpm? i mean if you just put in one of these things so you didn't stall when you put your turn signals on, wouldn't that do the trick?
