21700 upgrade, 18650 downgrade (flat-tops)
I was excited to see Liion start carrying this as previously I'd only seen it available elsewhere under the "new 2023 model" moniker (and for $7-8 more). I already had a PB2S purchased here that I'm happy with but was hoping the spacer and rotating "shim" of the SL would make it a better fit for 18650s. I actually prefer this version (the SL) for flat-top 21700s (like the P42A) which is short enough to be used with the spacer installed (and indeed requires that the spacer is installed). This provides a snug fit for the 21700s but leaves a nice bit of space for you to pry either cell out from the top with your finger (which feels better than just yanking on the ribbon). The spacer in this charger that's supposed to improve support for 18650s actually makes flat-top 18650s (like the P28A) fit *worse* than on the PB2S. This is because the spacer's contacts are very nearly flush with the surrounding plastic, resulting in intermittent connection with flat-top 18650 cells with even the slightest disturbance. On the other hand, the rotating shim works well enough and does keep 18650 cells from rattling around too much. Because the lids on the PB2S and PB2SL are exactly the same size, I think I'll be swapping them on mine. This way, the [PB2S + SL-lid] will keep my P28As from rattling and the [PB2SL + S-lid] will be slightly more pleasant to use with my P42As.
