7.4V 1200mAh Lipo Battery for MJX X101 WLtoys V666 V353B UDI U829X RC Drone-Pack of 2

I bought a pair of these 2S LiPo batt packs, in blue heat-shrink, stamped "made in china", used lightly for 1 year and never over or under-charged. Performed OK for 14 months, but now one cell of 1 pack has gone dead, won't fully charge, and gets hot on balance charger. So I'm taking the pack apart; will discard bad cell, and reuse the good cell in something. Good cell tests @ ~ 1400 mAh @ ~ C/12 discharge rate.The other, seemingly good 2S pack, tested for capacity (controlled discharge @ ~C/12), shows one cell has 1300 and the other 1370 mAh, so hopefully has a bit longer life. My sample is too small to generalize about mfg quality of these cells, but I suspect it may not be the best.

Fast delivery they work ask advertised I would recommend this I’m thinking of buying two more to power up my winch on my crawlers

The battery was delivered as described, but I bought it for my V-912 because it was compatible. What i didn't know is that it was too heavy for the copter. Couldn't get off the ground.

This is exactly what i needed for a summit VXL - cheap, 2400mah total (2 in series) and they both charge to the expected voltage. Of course if you are using a summit or other mini traxxas vehicle, you'll need to solder up some connectors, but as far as decent cheap batteries go, no complaints so far.

Nicely balanced 2s batteries.I am using these with my fpv goggles. They fit perfectly in my strap. They last much longer than the stock battery (1000mah vs 1200mah). Using a jst to barrel adapter.These batteries are very universal. Perfect for long range quads and other applications.

works as described but doesn't last as long as original but expected.

Good batteries at a good price. No problems.

Nice quality batteries however they do not fit without modifications in JJRC Tarantula X6.
