Looking for a battery

[hardbody]

Hello, I am looking for a replacement for this battery, this one was from Orbtronic but is not available.

Battery specs - 30A-40A 18650 3120mAh BUTTON Top Battery High Drain Rechargeable, un protected

What device are you using this cell in? Can it use a flat-top cell? I ask because there are many more options for flat-top cells (direct from the cell OEM) than there are button-top cells (3rd parties that modify OEM flat-top cells - aka "rewrap"), such as the generally-excellent 2600mAH / 35A discharge Molicel P26A - which is apparently available from Li-ion Wholesale in button-top as a rewrap.
