Mat be appealing to some, but it only works with 2 18350 batteries stacked

Also you aren`t going to do too much vapetime out of two 18350s

That may not be a correct assumption.

Stepping down (like this PV does) is a very efficient way to go and is also much easier on the batteries. Stepping down is always prefered to boosting in many situations. The Tesla, an electric car that uses huge banks of 18650s outputs 375V. A big advantage of a series battery configuration (7.4V) vs. parallel (3.7V) is that the series config provides a specific power at a lower current than the parallel, and thus the power loss is also lower.

Maybe not perfect, but here's an example. In the US we run at 110V, but there are many cases where appliances/motors can be had that use 220V.

Let's say you are going to install a 3kW motor in your house or shop and you can choose between a 110V or 220V motor. If you go with the 110V motor, it will draw 27A, therefore requiring a 30A breaker and 10AWG wire. If you go with the 220V motor, it is going to draw 14A, so you can install a 15A breaker and run 14AWG wire.

Here's a pic from the 10A OKR stepdown assembly data sheet.



FWIW the lowly Vamo can only manage about ~14W with a single 18650 (boosting), but with a pair of stacked 18350 (stepping down), switched over to VV it can mange about ~24W with a 1.3-1.5? atty.

Food for thought.

is there not a amp switch in the vamo though?
