boom.
i don't know your experience level, but would add a warning. if you have to ask, then you need to stop and think about what your life/health is worth compared to buying a replacement.
these packs have explosive potential. think small roadside IED. even when discharged or if the computer says there is 0% remaining. if you crush is or SHORT it out (ie when taking it apart) there is a real chance of you getting hurt. i would recommend against it.
been there, done that, have a ton of military training. not worth it to save a few bucks. my two cents.
best of luck and good health no matter what you pick.
