Sorry about the price difference but we decided to only sell SMC packs off our online site to keep prices as low as possible on the best possible packs. So much BS and crap in the Lipo market that it has become so hard to sell packs unless you play the BS game which I refuse to do.

You most likely got Gens Ace packs with Magnesium in the formulation these were very bad at holding up. To be fair I think the packs they sell now are using a regular formulation.

Just posted our new Race Formula 5600-70C pack info on our website. First shipment will be in next week. We have this pack on a great special until the end of December.
