is the EP cells. He is out of IB's and not longer carries those cells. The EP's are just better.
He has factory packs up in the store. He has more then that and are just not up on the site.

He is the in process of updating the web site. All the batteries are new stock with the lastest generation cells.
He also has stick prices but I don't know what the prices are. EP4200 cells same as the matched packs but prebuilt as a stick with a tamiya connector.
It depends on who you are and your level of driving wether you will tell the difference between mached packs. Matched packs allow you to weed out the bad cells and to find the high performance ones. You are talking about % points better though. if you are a novice to intermediate driver save the money and get stick packs and use the extra money for tires and shock oil and track time. When you get better then you will be able use and appereciate the higher end stuff more. That is my feelings on it all at least.
