Help!  Guys... I went to recharge the stock reciever battery pack that my Hellfire came with.  The battery got really hot and pretty much blew up!!  Can I just set it up like my Savage and use 2 Double A batteries instead?  Otherwise I have to drop $40 or so for another one of those packs and drive two hours into town to pick it up. 

Any knowledgeable input on this would be highly appreciated!
