    Pros: Real capacity was about 3300 mAh when I purchased, after more then month use it sunk on 3000mAh and stoped there for now. It has no hardcase so U must be carefull if U are using it in car like me. But it has good internal ressist and is really hard so there are no power fuctuance until end of battery. Therefore U need to be carefull and watch your time.

    Cons: The price with free shipping is pretty good. If you have a need of pro battery this aint one, but if you just enjoy weekend fun with your machine, this suits U right.

    Other: Good battery for the price, even though its capacity is lesser than written.

    Pros: bought this battery to try in a 1:10 rc truck, works fantastic! I got an approximate 20-30% performance gain out of 1:10 RC volano truck, just from switching to a lipo battery. Run time is approx 15-20 min, with my brushless system. Very impressed, overall build is good, and have had no issues with it so far, used it about 12 charges, no issues.. Also tried it in a no name rc car, night and day performance, wow.

    Cons: Where I live, batteries like this would run you any where from 40 to 80 bucks, depends where you buy. You can't beat this price, including shipping, its an amazing deal.

    Other: Can stress enouh, that for the price, including shipping, you cannot beat this deal.

    Pros: Best price around for this type of battery
    I believe the ratings are pretty close
    Run time is about 45 mins with a 3500kv motor in a traxxas stampede 2wd

    Cons: None

    Other: This is simply the best deal available anywhere for this type of battery. The rating is close as well, I read 3700mah on here but mine is in the 3850 range when charging. I believe the discharge rate to be close as well.

    Pros: Very cheap compared to 'normal' batteries of the same capacity.

    Cons: As stated, not the full 4000mAh's, but pretty close. Also enough for my use.

    Other: Not the capacity as advertised, but if you don't need exactly 4000mAh, why not buy them? After all they're a few times (!) cheaper then any other alternative!

    Involvement Level: Expert (understands the inner workings)

    Pros: Its cheap and about 3700 mAH which is pretty sweet for 22 dollahs!
    build quality is decent, connectors and handle currents over 20 ampers nicely
    have yet to find any major flaws

    Cons: Not quite 4000 but close enough
    takes long to arrive

    Other: One of the cheapest "4000" mAh lipos you can get. I'm considering getting more of these. After a couple of charging cycles it still seems to hold quite a punch.
    Wish they would print the real capacity on them, but considering the price its still a great deal
