  • Good Product for the money

    posted by stavesacre21 on 15:24:57 G9T 01/09/2013 certificated customer

    Involvement Level: Expert (understands the inner workings)

    Pros: Untouchable bang-for-the-buck in the 7.4v, 900mah 15C+ market, slightly thinner than most other batteries with identical specs

    Cons: No-name brand, Longevity concerns

    Other: For around $7 to your door, you can't really touch this for a 25C battery, much less the 15C battery that was ordered. I don't really see how you can go wrong for the price. Be prepared for a wait on shipping though. Shipped within a day but took over 2 weeks to show up.

    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.

    Cons: I couldn't find any cons.

    Other: It really exceeded my expectations I think I will buy more of these batteries soon.

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

    posted by joanpc on 15:10:03 G8T 09/08/2012 certificated customer

    Involvement Level: Expert (understands the inner workings)

    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.

    Other: It's really a mystery what you can get with those. :-) But you can take the risk for this price.

    Involvement Level: Expert (understands the inner workings)

    Pros: 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.

    Cons: This battery can not handle 15C current drain.

    Other: Use this battery for your helicopter. That's what it's made for. If however you desire to push tis battery to it's limits, don't expect sparks to fly.
    Thank you.

  • Great for many RC halicopters and planes!!!

    posted by gunkgrifter on 15:56:45 G5T 09/05/2010 certificated customer

    Involvement Level: Expert (understands the inner workings)

    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 one to have around. Long Life span is great also.

    Cons: Cant find any cons, maybe the plug wont suit your receiver. But other than that, none what so ever!

    Other: A cant mis deal. Go for it, you wont regret it, on the contrary, maybe more lipo's will follow ;)

  • Very good for LamaV3

    posted by ffranck on 16:58:07 G2T 11/02/2010 certificated customer

    Involvement Level: Expert (understands the inner workings)

    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 few more centimeters.

    Other: Very good product for the price.

  • Great battery for Lama V4

    posted by nasukaren on 00:44:21 G6T 17/06/2009 certificated customer

    Involvement Level: Expert (understands the inner workings)

    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.

    Other: Great deal all around, other places are 4x as much -- and you have to pay for shipping!

  • Amazing quality

    posted by SanderNijland on 08:20:15 G6T 03/06/2009 certificated customer

    Involvement Level: Expert (understands the inner workings)

    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 the heli to charge it.

    Other: Great lipo, small price. Works well on an dragonfly 4#1 and same sized heli's. If you buy this one, you wont regret it.

    Pros: -Cheap batteries
    -Cheap chargers available too
    -Can be used for just about anything

    -JST connectors and thin wires cannot handle high currents

    Other: These are good for the price but i am receiving too many defective units
