Zeee 14.8V 120C 1300mAh 4S RC Lipo Battery Graphene Battery with XT60 Plug for FPV Racing Drone Quadcopter Helicopter Airplane RC Boat RC Car RC Models(2 Pack)

strong batteries

I'll preface this by saying I was skeptical before ordering, and initially wasn't super happy as one of the packs had two cells that wouldn't balance. I contacted the seller, who promptly shipped a replacement for the bad pack. The replacement was exactly as described in the ad, cells balanced as they should.I wanted to give it a week or two before posting a review, so that I could get a few cycles on them. I've probably flown about 10 to 15 cycles on each now, and can say without a doubt that these are good performing packs. I'm getting explosive performance from them on my 5" and 4" quad, especially compared with 3S. Both quads are running 2205 2300kv motors, top mount battery on the 5" and bottom mount on the 4". Not only do they perform well, but they've proven to be durable as well. I'm not a great pilot by any stretch, and have no problem admitting to some recent crashes. As a result I had a replace a set of props on each quad, and even a broken arm on one. These 4S packs however held up great, even on the 4" where they were mounted underneath. I'll definitely be buying a few more.

Good quality lipo for the price

After a few cycles, these batteries seem to be holding up.Update: Purchased 2 more and one battery came with a bad cell. I was able to get a replacement. Thanks to the folks at Amazon customer service for helping resolve the issue.

I've been flying Rc for 25 years and electric for 15 years and these are the best battery for the cost ever. They are just as good as spectrum, Gen Ace and THOR. They are much lighter than most of my cheapest batteries like liperion, and all hobby king Chinese stuff. They don't puff and barely get warm under Hi discharge. They also have e a very low Internal resistance when charging all under 5 with over 30 uses

I am a newbie into the drones (But an IT/electronics guy).So bought this batteries as a starter kit for my iFlight XL5. One battery had dead cell on arrival(can't charge more than 3.8V) but customer support was kind enough to replace it!(Waiting on replacement).Second battery charges well to 4.2V, keeps it charge. Don't know about sagging yet as I fly very slowly and without full throttle.=========Edit:So after a few cycles one of the replaced batteries went also bad... one cell was reporting 0.7V.. But that's the lesson not to be cheap on batteries. Now I went to CNHL and happy! Just for extra $5 per battery.

I have several Zeee’s and I am very happy with them. They provide real punch for my 50 mm EDF, making hand launching a non issue. On one of the new packs, my charger only recognized 3 cells instead of 4. Amazon replaced it no questions asked. Great product and service!!!

Have crashed my FPV quad into the ground at 100MPH and "walked" away. Really been punishing these batteries almost every time I fly. Have had no issues with them. Plenty of power, very reliable. Probably going to replace one as it appears to be a little damaged. Can't be too careful with Lipos.
