Dormant Lipo Batteries

Hi guys,

so I havent flown my quadcopter in about 7 months and my Lipos have been in my room untouched since. I was just wondering, as Im about to start flying and filming again, is there anything I should do before I use them or charge them again? My charger is the Turnigy Accucell 6.
The Lipos and their current voltages just as I checked today are:

Multistar 5200Mah 4s (3.51, 3.58, 3.71, 3.70V)
Turnigy 5000Mah 3s (4.16, 4.15, 4.16V)
Turnigy 1000Mah 3s (3.85, 3.86, 3.88V)
Turnigy 850Mah 3s (3.80, 3.78, 3.79V)
Zippy 1000Mah 2s (3.61, 3.55V)

As I said these are the voltages of each cell after 7 months of no use sitting in my room. There appears to be no swelling to any of the Lipos.

Any advice is appreciated!
 
They're just fine. Balance charge them to even out the cells and you're good to go. The only advice I have is as they've been dormant, don't leave them unattended while they're charging for the first time. And if you don't have one already, have a fire extinguisher handy just in case.

Thanks for the help!
 
Hi guys the battery should be stored at 3.7 volts per cell , most times we fly after we land the battery is at 3.78 or 3.79 which is fine for storage , most 4 button lipo chargers have a store option so you can do this , if you can store in an old ammo box and recheck them every 2/3 months but they should be fine , if you leave a lipo at flight charge the chemical reaction will damage the lipo and they will puff and worse case catch on fire
