EX10 burn out

[thedarkness]

Today I received my new Nitecore EX10. I start it up on maximum power and within 1 minute the light start to dim to 50%.
I checked the battery and I burned my fingers ! Okay, maybe a
bad battery, so I took another battery (Surefire) but it happens again.
Unfortunately I sent the light back for replacement.
I was wondering, are you familiar with this problem ? What can cause
such a heat ?

Sounds like a short somewhere causing battery to be discharged rapidly, thus all the heat.

Yeah, toss that one back, glad you didn't have a venting incident!

You're not the only one with that problem. I sent my EX10 back to 4Sevens a while ago for the same exact problem. Great service from 4Sevens and I had my replacement EX10 back in less than a week from when I mailed by bad one back to them.
