12v system, 10000mAh jumpstarter pack?

[JerboaJohn]

I'm about to make another 4S Lipo battery pack and they run me about $50, so I was wondering if it'd be good to just try wiring in one of these auto jumpstarters as a battery?? my LED lights only draw 5-600mah so I'd gotten 4 3.7v 5000mah lipos before but these emergency jumpstart packs are like 20-25 online, and they are already regulated to 12v plus being 10Ah or more for half the money if it works that'd be great

How are you charging these made packs? Do you have separate leads for each pack?

Maybe one of those automatic charge controllers.

on the first 2 battery packs i made, the sla and the 1st lipo I had +/- bullet connectors jumping off, but the next one I have a 5pin balance connector to hook up to my wall charger, it's an Imax B6ac
