Blomiky 2 Pack 8.14Wh 7.4V 1100mAh 35C Li-ion-Po Battery with JST Plug for Wltoys A949 A959 A969 A979 A320 A321 RC Truck Cars and K929 RC Helicopter Airplane A959 Battery 2

good fit and lots of power for my drone

Bought these to power a couple of servos. They are perfect for my use and I am very pleased with them. I liked the products but they even sent me a micro fiber wipe which I used to clean my glasses lenses and my cheaters I used to read the tag on the box. I placed a lighter in one of the pictures for size comparations. They look to be about the size of a regular 9 VDC battery. But they have connectors that both come with their own USB adapter cable. And they shipped in a timely manner, and we're recieved quickly. I would highly recommend this seller, and may be using them again.

They fit my losi mini t2.0,!! Maybe 20 min. run time on the stock brushless system. I changed them to Dean’s plugs and have charged them several times and they seem to be working fine, the only reason I gave them four stars was because I saw the same ones without chargers for less money after I purchased these.

Highly recommend, I use in my HBX Rampage and Hailstorm. This battery along with the oil filled shocks change these RC's into one amazing little basher. You will not be disappointed I promise. Way more punch and acceleration and more than twice the runtime. Just be mindful not to run them too low because I don't think the ESC in the HBX RCs have a LiPo cutoff built in. Again I highly recommend these batteries. Thank you.

Great value great deal

This battery Will fit into the HBX Rampage truck. However it does give you more torque, so I recommend upgrading the axles to metal before using. Also, the vehicle really needs oil dampened shocks at stock speeds, so I recommend upgrading them to or you will have difficulty controlling the truck on rougher terrain.

Work great & the connections are way better than stock batteries. Highly recommend these batteries & the seller Blomiky!!! Shipped out fast & safe!!!

I purchased this 1100mah 2-pack LiPo batteries for RC use. One battery is fine, showing 1200mah and an even charge/discharge profile. The second battery has a weak cell, providing total charge of 950mah (under spec of 1100mah) and more importantly, at a discharge rate of 2A shows a voltage of just 7.7v instead of a normal 8.1v at the start. I attempted to use the provided balance charger, which didn't help. Finally I used my high-end balance charger to put it through a 5x discharge/charge cycle. It got a little better, but still only produced 980mah. Still 10% low. As a two pack, you can't return just one. It's a shame, and a waste of shipping. On returns be sure to use the box it came in which has the special label identifying that LiIon batteries are inside.When these arrive, be sure to measure performance. After 30 days returns are not possible.
