as i'm frequently learning about electrics and coming up with questions etc. i thought of an important one after speaking with JASON yesterday .
LIPO DANGERS AND SAFETY .
PREVENTION OF HAZARDS WITH LIPOS .

i'm becoming concerned about lipo storage as i now have 10 lipo batteries stored in an aluminium case on the shelves in the garage . that is a huge amount of energy .
being in the garage where 2 cars are also and also the garage attached to the house i am startting to stress and have safety concerns about them .
ok i do the basics like dont leave them unattended when charging etc , but one of my batteries now for example is starting to swell a little over time , is not lasting as long as the others in flight and has a cell that is .1v behind the others always . now is this safe after a flight simply sitting on a shelf 2/3 discharged ?? Can they just spontainiously combust ? i dont think so because i'm sure if they were potentially dangourous there would be regulations on storage , so i guess i'm probably unecessarily thinking of these as a danger , BUT IF I DONT ASK I DONT KNOW .
any tips on how to store these , i'm thinking of buying an outdoor cabinet , is that over the top ? or should they be stored in a LIPO BAG ? AND IF SO IS 10 IN ONE BAG OK ? ( BECAUSE IF ONE FRIES IN THE VICINITY OF 9 MORE , this could be a compounding problem .
am i looking too far into it .
i'm now looking at the safest way to have hazardous high energy batteries , safely stored .

WHAT DO YOU GUYS DO OR RECOMMEND ??
