Good news personal injury was avoided by your family and the fire department. I’m sorry for your loss of property.
I purchased a 12’ X 20’ carbonized fiber blanket and made my own LiPo storage bags. I store each battery independently within abag and then place them inside a fire resistant safe. I cycle my batteries every 6-8 weeks and keep them at the recommended stored voltage. I’m using the HiTec X4 charger along with extended balance leads and temperature probes. When charging the batteries they remain in the fire blanket and placed in a Crock Pot. I keep a bag of play sand handy if it needs to be placed atop of the Crock Pot to extinguish a fire. All of my batteries are Flightpower brand and equipped with Power Pole connectors. I never charge unattended.
Now, after discovering my Lipo batteries can catch fire ANYTIME, I don’t know where to place them for storage. The best place to store them is offsite / outside, but I don’t want the packs to be exposed to extreme cold temperatures during the winter months. I live in an area where the outside air temperature can be 90°ᶠ or -5°ᶠ. This makes long term storage of my Lipo’s difficult. I don’t want to decrease the mAh capacity or damage my expensive batteries because of extreme temperatures during the 6 month storage season.
Perhaps I should keep them in a Crock Pot and burry it in sand (below the frost line). It appears I’ll be purchasing a post hole digger before next winter. Doesn’t everyone need a post hole digger for their model aircraft hobby?
I don’t have any misconceptions my fire blankets and storage safe will contain a Lipo fire. Even if it did, the toxic smoke could destroy everything I own. I sure could use a safe and practical storage system.
Clear skies to all.
