Hextronic lipo puffed

[TommyP4000]

Hi

I bought 4 Lipos last summer from Unitedhobbies. It's the 3s 2200 mAh 20-30C (the blue ones).

I fly a T-rex 450 v2 with the 430XL 3700KV stock engine. Just sports flying, no hard 3D.

After 20-30 cycles, all 4 batteries are now puffed and they are not giving the heli the RPM that it should.

My question is: is this engine very hard to the batteries...?? Which battery do I need to buy if I want something that works with this engine (to a fair price)??? Are the new ones from Unitedhobbies better or what about this:

Any of you guys having problems with this engine when it is killing the batteries?? What do you recommend?

Thanks....

Your engine is fine. hextronik batteries are notorious of puffing. They even puff sitting on the shelf sometimes :)

Thanks....

Any chance that I can save my batteries?? If so, what can I do?
