I am wondering if we could use one of those
27 cell packs as a 14.4V jumper battery pack. It comes in a nice case with a handle. So you could charge it indoors for people who don't have access to outdoor charging. You would just carry it to your car and plug it in the cigarette lighter and it would maintain the voltage so the alternator wouldn't kick in... They are only $15.
I think I'll start a thread on that.
