Where do you guys buy your batteries from?

I'm looking for:
ZOHD Li-ion 18650 4S1P 3500mAh

or
ZOHD Li-ion Max 21700 4S1P 5000mAh

But they are back-ordered every place.

Is this common to be out of stock or is this part of the supply chain crisis?

Any recommendations for alternatives?

molicel does make nice 18650 and 21700 cells. sonys vtc6 are also nice.

Go to a Vape shop and buy some Molicel Lion cells.

You need some spare wire, tape and a connector.

Easy to build your own.

I get my cells from this vendor and always get authentic cells.
