Am looking for 1s/2s batteries specifically for my mobula (preferably 2S). The size needs to be narrow (cross section less than 20*15 mm)

Eg:

I tried searching a lot in local stores and websites. All of the available options are too big for a whoop. In particular I couldn't find any 2s options at all

Any stores/website, while restocking, Pl to stock upon some whoops and whoop Batteries. Whoops are a great budget way for people to get into FPV flying
