URGENEX 3S Lipo Battery 11.1V 2200mAh 35C RC Lipo Battery with Dean-Style T Connector for RC Airplane Helicopter Boat Drone and FPV 2Packs

Prompt delivery, item as described

So I ordered the batteries, fresh out the box, first one was perfect, the second one had swollen to about 1.5x the size of the first and I’ve been told batteries tend to explode then that happens

I was playing a stand ESC in a Wltoys buggy using this 3s LiPo for the first time. It leads to my ESC chip unit on fire. Ok, I thought it might be the ESC’s quality issue, even though the ESC clearly said it supports 3s Lipo. The first LiPo becomes swelled and I don’t dare to use it any more as I am afraid of explosion.Then I bought a brand new 120A ESC to replace the burned one in the Wltoys buggy. On the 7th time I played with the second Lipo in the same buggy with brand new 120A ESC, the Lipo is swelled again without any reason though the ESC is fine. So I am pretty sure it is the quality issue of the LiPo. I have to apply full refund. I would avoid to buy 3s LiPo from here.

These batteries were purchased for my radio control model power boat. The batteries drive the boats brushless motor smoothly and for the duration of the 5 minute race time with power to spare.The batteries charge well without excessive heat and deliver the power I require efficiently.

I needed at least a 20C rating for my 450 helicopter, but although they are stated to be 30C these only came out 10C, so were unsuitable for my application. May be OK in a small foam fixed wing trainer.

Good value for money- batteries work well for your money!
