    Pros:
    It looks a great construction battery. It is thin and has good capacity with a lower weight. It has a good price. It was exactly what I needed for my RC helicopter.

    I couldn't find any cons.

    Not 900mah, not 10C but you can use-it

    posted by joanpc on 08/09/2012 Certified Owner

    Involvement:Expert (understands the inner workings) - Ownership:more than 1 month

    Pros:
    Ok, this is not the best battery pack for your lama. But you can use-it and fly a little bit. After some cycles you can use-it to power your arduino or for other DIY adventures.
    Cons:
    Not really 10c, not really 900mah, but the price is great. After years of use the stock battery is much better than this one.

    It's a small package that's well made. Easy to solder on 'Deans' plugs and connect to anything. Cells remained well balanced throughout usage.

    This battery can not handle 15C current drain.

    Great for many RC halicopters and planes!!!

    Involvement:Expert (understands the inner workings) - Ownership:more than 1 month

    Pros:
    One of the better batteries found here on DealXtreme. This lipo's is really powerful in its own way. the most used medium could be a Lama V3 and V4, but many more choppers and planes can use this one. I wont say its the best lipo arround, but a nice cheap o...
    Cons:
    Cant find any cons, maybe the plug wont suit your receiver. But other than that, none what so ever!

    Very good for LamaV3

    posted by ffranck on 02/11/2010 Certified Owner

    Involvement:Expert (understands the inner workings) - Ownership:more than 1 month

    Pros:
    Very good battery for the price. I have not checked the discharge rate precisely but it clearly has more punch than the LamaV3 stock battery.
    Cons:
    The only small cons is the length of the cables. They are a bit short. This is not a big problem but it would be nice to have a...

    Great battery for Lama V4

    posted by nasukaren on 06/17/2009 Certified Owner

    Involvement:Expert (understands the inner workings) - Ownership:more than 1 month

    Pros:
    Great battery for Lama V4 users. A little bit of a tight fit, but last a long time and nice and strong. I also use this to power my servos on my 600 class heli using a separate regulator. So I'm happy all around.
    Cons:
    None. It's a cheap battery but runs well, so no complaints at all.

    Amazing quality

    posted by SanderNijland on 06/03/2009 Certified Owner

    Involvement:General (knows how to use it) - Ownership:1 day to 1 week

    Pros:
    They work very well with my Dragonfly HM4#1 with superskids. Compared to the stock 450mah battery with the 4#1 this thing is a rocket.
    Cons:
    The only downside i could come up with is that the connecting cables arent very long, so you need to remove the battery from th...
