Acebeam 14100 battery? Just purchased the Tac 2aa and found out it comes with a battery I’ve never seen. 3.7 volt, 14100 size, 1800mAh with USB-C charging port. I consider myself quite the battery geek so my ego took a real hit when I saw this. Having searched the Internet the only place I can find to buy this is on the Acebeam website and they have $50 minimum. I’m hoping to try this in my convoy T5 As well as my AC beam. Is there another place to buy this battery other than ace beam so I don’t have to buy six of them to meet their minimum?
You mean 14mm diameter and 100mm long?
Would that be called a 141000? 
I think the 2AA pokelit comes with the same cell. I contemplated buying one from AliExpress but I don’t know if the driver of my 2AA lights would appreciate the higher voltage!
There a few companies that they are using this type of batteries for a while…

They should be referring to it as 141000.

There’s, maybe, some system requiring usage of only 2 digits per dimension. Another example - 32140.
I could be wrong, but I seem to remember the last digit being either a zero or one indicating a cylindrical cell or rectangular cell.

You’re not wrong.

You can buy another light for $25, this will get you a spare battery and spare light.

I messaged the Acebeam store on AliExpress, they confirmed they don’t sell the cell through AliExpress
