I'm also curious what advantages raptorlightning's load sharing board offers over the dirt cheap and seemingly ubiquitous TP4056 module? 5PCS Micro USB 5V 1A 18650 TP4056 Lithium Battery Charger Charging Board New | eBay

To me, they look like they perform the same function and I was under the impression the draw of the PCA is <1A, but once again, I know very little.

It is a good electrical insulator that is heat resistant. It conducts heat well enough to be used as a radiative absorber then conduction to the metal.

I use the cheap eBay ones and they work fine.
