Patkin... been on vacation only had an iPad and I'm new at thatSaw your earlier post - not sure what may be happening but the eGo-c upgrade is the safest eGo. If you can only run in regulated mode that should work well. I figure you know it well since you've had it a while but some don't know that you have to 5 click to turn the batt on after switching modes. Stumped me at first... ;-) I've had one upgrade come out of mode during charging - but went back into mode easily and with no problem and didn't do that after that one time. Don't know why that happened. And I've had a few that went to 'lifetime death' without the problem you're experiencing.
Again, you should be good in the one mode though.
KentC, is the Halo Triton a clone of the eGo-c upgrade??
I have about (mumble -six) of them at 900mah each, believe they are regulated at 3.7v under load, and LOVE them.
They have that bizarre 808-inner thread + eGo skirt outer thread, which makes toppers a challenge (so far only SI and Halo carry them), but I still love mine.
Any ideas?
