Has anyone used them ? If so what is your opinion of them ?? I am also wondering if they are as good or better than the IB cells who's matching them and are the numbers and batches looking good on them ????

Pro-Match is selling them. I bought 3 packs in April. The #'s were good, and they ran good on the track. They have the same problem as the IB's. They want to self destruct (dicharge) when stored. I liked them, the 3 packs I have are about done. Always had good results with Pro-Match products. Check out his web site.

Don't waste your time buying anything else.

Promatch is the BEST!! :thumbsup:

EP cells from ProMatch are the only way to go. The voltage is a bit lower than a IB but still 1.23+ but run time is good 460+ All cells will dscharge under storage but EP will out last any IB's. But if you need crazy voltage ProMatch has IB's in stock also 1.25 voltage 420 runtime...

Toby you have a PM

This is the absolute first I've heard of this. I have tried a few packs of these, have abused them mightily, and they keep coming back for more.
I run IB's from JRB due to having a little more pop. Gotta be honest, though... for the price and reliability, hard to pass these cells up. Also, Pro-Match is one great matcher. Good products and service. :thumbsup:

Anyone heard of or had experience with the Slingshot cells?

Hey guys thanks for the input both here and through PM's. I'm thinking of getting one or two of each and see how they do.
