I dont understand why you can't make them.. I'd recommend going with the 6 cvell packs anyways, my 2400 7 cell matched packs didnt last long at all.. they take a while to peak, and still get used rather quickly.... but if u buy a lot and have a couple peak chargers i guess it wouldnt be to bad.. check ebay, otherwise i say jus get the cheaper orion 3000mah packs for long fun times with the emaxx.
