You just can't go wrong with the Pro-Match Ener-G 4600's http://www.promatchracing.com/

Yeah, those seem good. However, I have a credit with Trinity, and they don't carry the ener-g cells.

if you have a credit to use up, go with the EP's. then after that, start buying Ener G cells from SMC or whoever is carrying them.

IB4600 perform slightly better than EP4600... They have a little higher voltage, about the same runtime and IR. My IB46s cycle out slightly better than my EPs and on the track they seem a little faster. In terms of reliability they are about the same right now.

Ener-G cells are proforming really great to date among many racers reviews. Many have great comments about them. Also the EP cells have nice results. Both may not yeild that Killer label # but produce in the cars on the track where proformance speaks.

I only do club racing, so reliability is more important to me overall. My IB 4200's were tempermental, and so i'm hoping to have something a little more reliable.

From what I can see the IBs and EPs are equally reliable. Here are some GFX first cycle numbers after assembly:

IB4600 1.238/480
444 r/t
7.41 av
11.0 ir

EP4600 1.235/465
422 r/t
7.39 av
10.9 ir

I have two IB4600 packs from Trinity. Im not a Trinity fan, but the packs work great and have plenty of run time. No problems to date.

I would agree with ghuber. IBs seem to be coming up with slightly higher averave voltage and the EPs are giving slightly higher runtime on average. Really, the cells are so close in performance that if I didn't see the labels I wouldn't be able to tell which is which after they come off the matchers.

If reliability was the primary concern then it's hard to beat EP cells although the IBs look good now from my limited track testing and cycling.

I have the ener-g, EP, and IB 4600's and cant tell a bit of difference between them, I run them on a 3.5 brushless 5 min indoor oval, they make run time and more power than I could ever use

Give the E-Power Cells a try. They are super reliable and great performance. Voltage is 1.23+. Second choice would be the IB4600s.
