    considering 8.4v 5 series batteries for my 3903 E-maxx

    looking at getting 2 8.4v 5000 Traxxas batteries for my stock brushed E-maxx -will the the extra 4000mAh over the stock 6000 be noticeable? (16.8- 6000 w/ 2 3000's) stock -(16.8- 10000 w/ 2 5000's)

    OR should I bite the bullet and go hard case 7.4v 7000mAh lipo (x2 would be 14.8v-15.8v- 14000mAh+)?

    What would you do?

    cost of the 2 8.4's is $98 shipped

    cost of the 2 lipo's is $163 shipped

    then I'd also have to buy a $90 charger as well (just have a DTX 200 right now)

    With the exception of the up-front investment, everything is better with LiPo! Longer run times, better discharge curve, less overall weight, better speed. There's really no comparison with NiMh.
    Make it idiot-proof and along comes a better idiot

    I see I know the weight advantage for sure - I had a Venom 7.4 8000 in my 2wd Slash last winter and it was a ton of fun and that lipo weighted 1/2 of what a 8.4v NIMH weights

    hmm it's overall a $60+ difference and I'm just a basher not a racer and run times are not really a concern as long as they stay over 15 minutes (it's cold out so I doubt I will stay out longer than that.. )

    When you run two batteries with the stock EVX2 voltage doubles, but mAh does not.

    As a matter of fact, it is impossible to run two batteries together and be able to double capacity (mAh) and voltage... you can get either or, but not both.

    Running them in parallel doubles mAh.
    Running them in series doubles voltage.


    I would suggest getting a pair of SPC packs...
    ANY two of their packs are much less than $163... probably even shipped... and depending on where you are, they might even be less than $98.

    Hard case; 5000mAh/30C/2S/7.4V for $27.95
    Hard case; 5400mAh , 50C, 2S, 7 .4V for $45.95
    Hard case; 6500mAh , 50C, 2S, 7.4V $39.95

    Hard case; 6500mAh , 65C, 2S, 7 .4V for $59.95

    Soft case; 8200mAh, 50C, 2S2P, 7.4V for $45.95

    Whatever it is I just said... I could be wrong.

    I see! I don't know why I spaced out the mAh doesn't double in series haha oops..

    Make sure they fit... I think they do but did not check dimensions.
    Shipping should be quite reasonable since you are within the states.
