Probably, no one has come up with a better plan. And for the most part if you compare capacity to capacity the prices are pretty similar. If I get the onyx charger which is $50 cheaper I still got to buy a $50 dollar balance adapter, so that is just a wash. And maxamps seems like a good company. I'll probably order one setup so I can get my discount up then order the second, only like another 5% but hey it helps.
