Default Stock class Battery voltages

Im in the market for some new batteries and am looking to go with a pair of 4200's to start with. I was wondering if anyone could give some input on a good voltage range to be in with a stock truck. The 3800s i have are only 1.12-.19 and they have just been getting flatter and flatter, time for new.
Any input would be great and thanks ahead of time.

You should be looking for 1.21+ and IR under 2.0 for good 4200's. Low IR is just as important if not more important to high voltage for stock racing as this will effect the punch out of the corners. You may want to check out the EP4200 as well. They have been proving to be pretty amazing batteries.

A couple top matchers are starting to carry the EP cells.

I would check out Team Kwik as well. I bought a couple "practice" packs that they were selling here, one of which was 1.245+!

IF they are GP4300 then you can race them.

Check out www.roarracing.com for a list of the approved batteries.
