    (2)5250mah 3s or (2)8000mah 2s maxamps

    I'm wondering what I sould run this year racing/bashing on my twin vxl brushless setup. I've run a (2)2200mah 25c 3s and its sick but I don't get alot of run time. I've also tried (2) 4000mah hv 2s maxamps and I wasn't as fast, but fun and it did last twice as long. Will the 8000mah 2s give me alittle more power then the 4000mah, or should I go with the 3s 5250's?

    I would go with the 3s 5350 if you did not like the performance of the 2s batteries. Mah gains wont really make it more powerful, just last longer per charge.

    Thats what I'm tring to find out if the 2s's with be enough power to have fun and race some 1/8 scale truggy we race at our local track.

    You could split the difference and go with two 5s packs, run in parallel. That would give you more voltage than the two 2s packs in series for 4s, and it would let you run larger cells (overall) for more capacity than the two 3s packs in series for 6s. That's what I am looking at for my next project. Check out ***** battery packs. I haven't heard a bad word about them, they are priced much less than the Maxamps packs, and they are available in all sorts of voltages and sizes.

    Nice idea, but he cannot do that with the dual VXL setup. They can only handle 3s max.

    I hate to admit this but the (2) 3s is just to **** fast, **** I must be getting old to admit that LOL. But I just want to be able to go fast around a track, be light weight and last along time. Hummm. maybe the 8000mah or smaller mah 2s is the right thing for me.

    Then go for some good 2s packs then. I do not blame you, there is certainly such a thing as too fast for normal running!

    Man, I run 2s 8000's (True RC and MA) at our local track all last summer. Never had a problem with the truggies or with power (and it's a big MX track).
    The run-times were amazing and it is a light set-up.

    Big difference between racing competitively and doing speed runs. Stick with 8000's for racing....

    4s is a great voltage for racing, you just don't need more... at 14.8v any decent system stays cool enough. The only reason to go to 6s is for the slight reduction in temps so long as you gear down to 40mph range. On a race track anything over 45mph is going to cause you more bad than good, it is a lot more difficult to handle even for a good driver.

    As far as how long packs last in terms of run time..
    14.8v*8000mAH=118400
    22.2v*5250mAH=116550

    You really won't see much difference between those two setups geared for the same mph.

    Now for the funny part most don't consider, a 4s (14.8v) 35c 5000mAH lipo will hold voltage under load as long if not longer than a 15c 8000mAH lipo if you are pushing your system hard at all, now it maybe another story if your just driving around like a grandma, but out on the race track you will find that to be the case.

    I've got 3 sets of the 2S 6000's 25C, 1 set of the 2S 4500 30C...if you call and speak with someone there, a sales person or POS desk, you can probably get these (2S 6000's) for $85. If you buy like 4 or 6 at a time, they would probably apply a heavy discount again on top of those prices.

    They have become my battery supplier except for the Zhino's from *********. Those are great too, 3S 4900's 20C Zhino (***** brand)..http://www.*********.com/*********/s...0C_Lipoly_Pack
