MGP-BT-2600M-3S-25C-B:MG Power Li-po Battery, 11.1V 2600mAh 25C Banana Connector for Walkera v450D01, V450D03, V400D02, FPV400, QR-X400 Helicopter

I purchased this battery for the Walkera QR X350 and it has been listed at other sites as compatible with the QR X350. I find it to be a bit too thick and requiring an uncomfortable amount of force to slid it in the battery compartment of the x350. I fear it will cause fatigue on the circuit board and in the long run lead to premature failure. I plan to contact MG Power regarding this issue.I decided to re rate this battery since it is a good battery with a good price (25C and 2600 MAH). The merchant clearly did not list the QR X350 as a good fit for this battery. I also have the QR400 and it works excellent with that quad.So just be aware that if you are looking for a battery for your X350, this one may be questionable.

Great battery!! Great price. I bought 2. I got my Walkera V450D03 from China. It would have cost much more to ship with battery. I opted to purchase separately. These batteries are great, and work perfectly with my helicopter. Even in what I call extreme 3D mode. Which to an really good pilot is OK 3D.

Only after about five cycles, the battery exploded inside my RC helicopter. I do not recommend this battery...it's weak and a fire hazard.

This branded battery is a good choice to either replace or for a spare to enjoy flying the Walkera V450D03 helicopter. Have enjoyed at least 10 minutes of flight on the battery.

Received a mildly bloated battery, and it's since gotten a little worse.

Battery was defective and not happy at all

i love these, their my go to batt's when i'm on the field flying around and kickin it in the park.

nice
