Was chatting to my mate at Grafton City Batteries yesterday re these batteries.He said check your lithium batteries often if getting hot be warned that they can explode at any time as happened recently in a van fire in Nthn rivers.He will no longer fit L in vans etc untill an Aust standard re fitment etc is mandated.He also has seen premature failure in solar power house set ups which he fits. .There is a Aust std for these which includes a fire proof enclosure!Finally these batteries are not easily to recycle if at all in Aust.Therefore he would have to store them himself which is not an option.
