So I purchased to 2 slashes they came with 2 3 cell lipos. These batteries have been charged on a non balanced charged. Obviously they need to be tossed asap and they will. One is very slightly puffed.

But here is a question. I ordered replacements but in the meantime if I were to charge the battery outside in a lipo safe bag. and keep them outside. Is there a real risk? My thought is to use them for a few days an keep them outside. if they explode while changing they will be outside away from the house on a cement slab.

This okay?
