Looking for a 18650 charger that has a built in Internal Resistance tester.

I'm looking for a charger to recharge my 18650 battery's for my vaping stuff and flashlights.

I have seen battery chargers before that charge 18650 battery's that have a built in internal resistance tester feature built into them but for some reason I can't find one with the internal resistance feature.

The reason I'd like to get a charger for 18650 and 26650 cells that has a built in internal resistance tester is to be able to test different new cells.

The lower the internal resistance the more charge's you normally get from battery's and it also means a better quality battery.

I used to be into RC car's and boats when I was younger and that's how I know about the internal resistance thing.

A lot of people swear by this one.

The xtar VC4S has an internal resistance measurement and also handles the bigger 21700 batteries.
