Some years back a freight aircraft carrying a wooden crate of Li-Pos crashed into the Florida Everglades because the crate had been mishandled from freight warehouse to aircraft and the batteries had caught fire,
The fire in the aircraft hold burned through the control cables and all on board died,
Li-Pos are no longer allowed on commercial aircraft as airfreight.
I use Li-Pos and like Crius I use a battery charging bag and I NEVER leave the battery in the Tank unless I am using it,
I can confirm that Taigen have said using Li-Pos in a Taigen Tank voids the guarantee,It is clearly written on the paperwork that comes with the Tank well it does on Taigen Tanks in the UK.
