Actually, the spc lipo is better quality. Maxamps has been raising their prices tremendoudly, and they STILL do not say who's cells they use! But for the money, you can get 2 Orion 3800 2s lipos, which are $90 each, and they rarely ever need to be balanced and are very high quality cells. Those would be $10 less than the maxamps pack, hardcased, way more powerful, and you get 2 of them.
