    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 OtherThoughts: Although I ordered the (2) 7.4v 900mah 15C batteries, I was sent (2) 25C versions of the same battery (black instead of green packaging). From the short amoun... Read more

    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. OtherThoughts: It worked perfectly in my RC helicopter. Now, it flies around 15 minutes with this battery (it is much better than my previous o... Read more

    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. OtherThoughts: Buy-it for your... Read more

    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. OtherThoughts: I bought about four of these batteries in all and have used them for various purposes. One of the uses was to power a flashlight...

    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 th... Read more

    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. OtherThoughts: With a LamaV3 this battery... Read more

    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. OtherThoughts: The micro JST connector is standard on... Read more

    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. OtherThoughts: Package is not damage proof. The pac... Read more
