18650 and the vamo

[hvac999]

I use the Panasonic CGR18650CH batteries and they work like a charm.

...But if stacking is bad how do most laptops get away with it?...

Laptops aren't pulling 3 Amps or more out of the battery for many seconds at a time continuously.
Stacking itself isn't bad, the differences between the internal resistances of the cells is what's bad, and this difference is amplified as the current draw of the load increases.

If you could get a perfectly matched set of cells it wouldn't matter, but it would require labor, sorting through all the cells and matching like cells. So it would cost more.

I bought these for mine, hopefully they will work ok.

This is what I have, working just fine. No protection on these.

I had the same problem. The brand new Vamo I got won't work with the protected battery I bought. I have to drive an hour just to get a battery that will work. Really want to try out my new Vamo.
