You cannot removed the metal case. They are very similar to NIMH cells. The main difference is 1 lion cell is 3.7v and 1 nimh is 1.2 v.


I just ran a 4s pack for 15 minutes and only drianed off 1 volt. Used in an E maxx 8xl setup. roughly 2000 mah was drained off (still chargeing). Motor was warm batteries did not seem to change temp. cold to the touch.
I can see 35 min run times REAL EASY.
Need 10 pick up a 12v alarm.
