Just yesterday I put my CRT back together with my new MMM, and I thought something was very wrong. When I went to drive the truck it felt like I was running on 8 NIMH(really was on 5S). My truck would have gotton passes by an XL-5 rusty slow. Ends up my batteries had "FROZEN". I put them in my pockets for about 45 minutes, and went for attempt #2. It was like a 400% power increase.

Thank you all guys.
If I do nothing about the cold lipo, what will happen?
Usable capacity and punch reduced greatly temporarily? or cycle life shortened forever?
