I honestly would never buy IB 4200 again. I don't know how the new IB 4600s are or will be--but I have been running these (matched Grepow 4200--pink cells) and they are awesome--1.22 at 35 amps, no venting, no self discharge--1.6 IR--$45 for six matched cells--great price--virtually as much punch as new matched IB 42s.


Also the Speedzone E-Power 4500s (on same linked page) are supposed to be outstanding as well--and they have a really good price right now of $50 (6 cells)

The Grepows do not discharge in 2 days, I have zero venting on any cell, and virtually the same power as IBs. My IBs ALL (3 packs)have vented to some degree, and I am always worrying that I will lose a cell during a race. And I have had 3 cells (in 3 packs) go bad. When they work they are great, but its just not worth it when you have cheaper, more robust cells like Grepows and E-Power available that are just as powerful.

One cool thing about the Speedzone cells is that the matching labels have the date (month) when they were matched--so you know you are getting fresh cells. As opposed to my IBs, in which half of the cells arrived with 0.0 volts!!

Dont want to dumb down the question but when you say "best", best for what?

Bashing,club racing, nationals?

Or best from which company?

If you are club racing it is crazy to be spending your hard earned on top spec matched cells. Chances are you are going to notice little,or no difference between a good set of matched cells and soldering up some unmatched loose cells if you're at club level.

Yes, IB42's can be unstable but with good soldering technique (good solder,bars and iron,scuffing the cell ends and not heating the cells up for too long) get yourself a good few loose cells for 2 sets of 6 cells and see how you go.

If you are racing with a demanding 3.5 or similar though, then yes my opinion would change greatly. A 10.5 should be fine with unmatched cells at club level, you will still have power left at the end of the run.

I guess it just depends how much more money you want to throw in for matched cells to get the extra "zing"

Honestly, I cannot recommend even EP cells at this point. I follow the Electric onroad thread very closely, and now there's a new thread with pics, reports on EP4600's as well as the "improved" IB4600's blown to pieces on first charges. This scares me to death since I just purchased 2- 7 cell EP pack for my new Emaxx. So far they have taken a charge, but I honestly dont want to get biten by this reliability problem. I do run lipo as well and would prefer never to buy another NiMh product again, but the offroad track I frequent is still in the dark ages and hasnt allowed lipo use yet.

EP4200 cells have proven to be extremly durable. The new 4600 and epower 4500 I have yet to play with my self but the EPower 4500's seem to be holding up well so far.

I'll second what Casper said...the Slingshot Batteries EP cells are bulletproof! We ran the same packs the entire year and abused the heck out of them. I recommend them highly.

Happy New Year!
