More like Crazy Mofo's About To Blow Up The World!
 
I was reading up on the C.H.I.P. forum and ran into one of their threads about using batteries on the C.H.I.P. I have to say that these Mofos are crazy! The issue is soldering on the Li-Ion batteries, which can cause it to fail catastrophically (ie: Li-Ion Battery Explosion and Fire)!
 
But they got some interesting results. I so not know if one can read the forum not being a member but here is the link. These guys are taking Li-Ion batteries from where they can get them - ANYWHERE!!!  
 
As you know, such practice an theory can work on the R-Pi and other Pie Boards. I must say it is interesting.
