7 reviews for 11.1V 3000mAh 3S Cell 30C-60C LiPo Battery Pack w/ EC3 (EC-3) Connector Plug (E-Flite Blade 350 QX2 QX3 AP 450)

  1. Curtis Mattingly

    I purchased 2 of these batteries for my Blade 350 QX#. I was very pleased to see the smaller sized battery. The first flights were flawless. We’ll update again after 1 month. If they’re still good, we’ll be back to buy some more. So far, they’ve been much better than the original batteries.

  2. Rod Toler

    This was my second purchase from Dirt Cheap RC. I had purchased the same battery a few months ago. I was pleasantly surprised with the smaller size. Your battery is over an inch shorter than the OEM battery that came with my quad. This makes it easier to install in my Blade 350 QX3. I was also impressed that I still got the same flight time. Unfortunately, the first battery I got from you failed on the 5th flight. It was not the battery’s fault. A pine tree reached out and snatched my quad out of the sky at 90 feet. My quad suffered two very strong thunderstorms and high winds that night. The battery was not so lucky. I plugged it into the charger and there was no love given in return. The light on the charger didn’t even switch on. I assumed it was toast. So, I bought 2 more. I will be flying them as soon as the PK Index drops to acceptable flying levels. Thanks.

    I have had the pack now for about a month and have at least 15 flights on it. The cell voltage remains constant on each cell so far. The power is great and it balances charges right on the money. I just bought another one today!

  4. Russ Shanks

    This is a perfect extra battery for the Blade QX3 quad. It’s shorter than the Eflite and just as much power and mah’s. It is one of those win-wins. I have about six flights on it and all cells are staying charged and balanced well. I will be buying more!

  5. Rick Bartoli

    These work really well and are lighter than the oem.

  6. Tom Acimovic

    Everything was good and prompt. Thank you!

    I ordered four of these as a backup for a Blade 350 QX3. I had run into some issues beforehand in trying to find batteries that fit the Blade, as well as supplied the 3000mAh that was standard with the battery that came with the unit. My overall impression is that these batteries fit the bill. Not only are they smaller than the standard battery (in length mostly), but they seem to supply the same amount of power, if not a tiny bit more. If you add on the fact that these run ~1/2 the price of the standard battery, it makes me a happy customer. If I ever need additional batteries for my Blade, I’ll be purchasing this model.
