Could anybody recommend which kind of battery cell with more punch for stock race?
I don't care even smaller capacity than 4200's, like:RC2400, GP3300 or GP3700, please.

Best regards

Well I would say the GP3700's would be were close to the 4200's.

As i know EP4200 has released M3.
Between these 2, which one is better?

I usually drove 17t class and IB4200 SMC is the best punch of all..

The on track performance of the new EP4600 is very impressive, the batch that everyone is doing right now is very good.

EP4600?
I have only heard EP4200M3 before, could you show me where could see this cell and how much V1,?? could it put?

I think it is pretty hard to beat the IB cells for punch right now. Team Orion has a new cell coming out so we'll see how those are soon.

Hi Mac, the new EP4600 is going to be avail from almost every matcher very soon including the company in my sig. There are a high percentage of cells over 1.23v+ at 35 amp with 460-470+ seconds runtime. There is an actual EP4600 thread here somewhere. My packs are due to arrive today. The testing of these cells have been very positive and I am looking forward to giving them a try.

I have my batteries here I just need to finish them.

Hi Jeffb,

Have you tried weighing the new EP4600 pack compared to EP4200 pack? pls post weight difference. thanks!

No problem give me a minute or two.

O.K. looks like the new 4600 cell is about 72 grams each on my scale and the older 4200 is about 70 grams on my scale.

The #'s did not show up in the pic but it says 433grams, I'm guessing there is a gram of glue?

Add about 2 grams per battery bar when it is complete as well so about 445~ grams when complete.

jeffb,

Thanks for the info, im still waiting for the release here in the philippines. by the way, have you tried it in brushless motors specifically 3.5 or 4.5? how was the run time?

if you are worry about the weighs, i think 3700 is little lighter than 4200.

I have not tried brushless yet, but runtime looks to be pretty good. If one thing is for sure the voltages are higher than the EP's used to be.
