Twins addes to Provari Mini battery issue.

[CoyoteRed]

I have a provari mini and decided to add the Twins battery extension tube so I could use 18650 batts.
I have Panasonic CGR18650CH batteries,ICR 18500 1600mah battery and two Trustfire 18650 3000mah batts.
The only ones that will work are the Trustfires? Any one have any idea why that is.
I've checked all batteries with a volt meter and they all are charged to 4.2???
I have checked the battery post inside the Provari and have made sure it is clean,anybody have any Ideas????

Those Panasonic's have the "Button" top?? If not that is what your problem is....

You are right,They were not button top and it seems that is the only thing they can use. What confuses me about is that when you look inside the Provari I do not see anything that looks like it would prevent a flat top from working.

I purchased 2 AW IMR 18650 from Provape and they work fine.

Thanks for your answer, but I still cant figure out why flat tops don't work....LOL
