Default Help required choosing new cells?

Hi I am about to choose some new cells and I need a little help I am worried about the reliability of the new IB4200's (ie I keep hearing people say they blow up and vent alot) so would I be better of using matched 3700?

I am only running Stock class but everyone else at my club runs the 4200's

I really need these cells to last a year if possible due to the costs!!!

I also need to know if I will really notice a difference from matched cells as they are alot more money than the zapped cells?

I hope you all can help

Many Thanks

it depends on the competition you are racing against. If they are as good as you and run 4200 then you must use them as well

If not then you might be able to still beat them.

On an equal level IB4200 are better but as you said they have some issues. I have been informed that the newest cell is much much better than before. Not discharging as fast not reaching high temperatures when charged

I would stick to the matched cells if you want to chase down the leader.?

But.? If you aren't ready to take a lot of care in cycling them just get unmatched, or even better Lipos.

I personally believe the GP 3700 was the last hearty long lasting sub-c out there.
I never had trouble with them and you could dead short them.
Mine well lasted a year. They are awesome for stock.

The battle has begun. I used to charge mine at 5 amps, and worked great.
The guys running 4200's were punching them out at 7 and 8 amps.????
Why.......I think they were trying to get some punch. Thus probably why they are venting, trying to get some power out of them.
I tried them all. 3800's and vented one. My 4200's were to weak for stock and would get hot. I sold them with in a week of owning them and went to Lipos.

I have the Whip-Lash Matched 4200 6 Cell Pack. Soldering them was a Pain but in the long run ive noticed from my Trinity 3000's to these i get so much more power and a really good amount of extra playtime. im actualy buying 3 more sets this friday. very good in my eyes.

I charge mine at 4amp's and it only takes about 35 - 40 minutes.
