I have never heard of a stock ecigg battery exploding,the only ones I have heard about exploding were unprotected cells in series, the cell on the m401/2 is built into a housing and it is an OEM cell ,I doubt you will be able to give them any info other than voltage and mAh.You could get creative and make a jig to clamp the battery in that has a contact to press against the center contact and an aligator clip for the threads.I really don't see where you will be gaining anything.The Chinese engineers who create these kits are way more inteligent than we seem to be giving them credit for.When used properly you will have less trouble and get more vaping pleasure from a stock ecigg kit with less hassle and less money spent.It is inevitable that all eciggs will malfunction after a time ,I feel less bad about having something I paid $20.00 go bad than something I paid $100.00 for.But that is me.
