Lama V4 LiPo Battery Expansion ?
Hello,
I flew Lama V4 in open ground, under no wind condition.
There were some 'not so soft' landings, but Landing skids are intact !
After 9-10 min when I tried to take out battery (original Esky which came with heli), I had difficulty. It seems battery has expanded very slightly ?! I measured each cell Voltage, which is 4V.
I will try to take to LHS so they can see if it OK for use.
Comments welcome.

RE: Lama V4 LiPo Battery Expansion ?
I flew with the battery. 3-4 minutes into the flight, heli started comming down fast, at same throttle position, so I increased throttle and it gained height again. Same thing had happened on last flight, on which slight LiPo expansion occured.
(I'm a beginner & have only a few battery cycles total experience on Lama V4 and LiPo, so do not have anything to compare with. I fly in flights of about 3 min each)
So I'm still little concerned if battery is OK ?
