[NSRCA-discussion] Battery puffing question?

[MATT LIPRIE]

Anthony, I recently had a puffed Thunder Power pack.  I let it cool down and 
the swelling decreased; not all the way, but enough.

I decided not to take a chance by cycling them again so I sent them back to 
Thunder Power, and recieved a new pack for a discount.  I believe that would 
be the best way to go.

Regards,



Matthew Liprie
