[RE-wrenches] Second Life Batteries

[Drake]

Hello Wrenches,

I've been contacted by a group who will be taking apart lithium ion 
battery packs that have been retired, finding the bad cells and 
recombining the remainder, then putting them in larger configurations 
for use in PV systems and electric vehicles.

How can thermal runaway be avoided? Is there any information that 
could be of use in making these systems safe and effective?

Thanks,

Drake
