Hi went out for a fly today and took both my batteries the new one I have performed excellent but the one I got with the phantom used and was told wasnt used much seems to be having some problems, when I went out last time I noticed it drained real quick and just thought maybe i hadnt charged it up all the way but today when I put it in the charger it charged for maybe 20 mins and said it was full, hit the button all lights lit up saying it was fully charged went out for a fly and checked it in the first few mins of flight 95 % then after a few mins of flying it just seemed to lose juice real fast before I knew it I was getting beeping low battery, and ides why this is happening worked fine before the last 2 flights, the charger even said it was charged when all the lights were green and went out...

Can you check it in assistant and see if the cells are close .

You can also hold down the start button (out of the P2) until it starts flashing and see many bars are lite or flashing.

No. What it would tell is what percentage of battery life is left after charging.

Basicly the same as hooking it up to the software which gives you the same info +.

Cell#1 (3794)
Cell#2 (3794)
Cell#3 (3782)
percentage of life 96%
every thing seems normal what do you guys think?

No battery expert but one is alittle low . Don't know if that could be your problem but maybe someone will see those #'s and tell us !! Is your battery swelling any ?
