Main N-FET: DTQ6200

Red N-FET: DTQ3300

Active balancing: ETA3000 (possibly set to 2A)

The light does trigger USB PD for charging, it was drawing 26W in a quick charging test. Nice.

The USB-C port has a rubber seal around it, not sure if that’s just against dust or actually a waterproof sealed port. But nice to see there’s a second layer of protection behind that rubber flap.

I was quite eager to find out how they solved the rotating battery contacts in this (since the batteries are in series), was surprised to see they didn’t use some kind of leaf spring for the wiping contacts.

It’s a bit disappointing to me that a $200 light (when not on sale) like this doesn’t come with a high power boost driver, but what is essentially just a buck + FET driver. That explains the big jump from high to turbo.

Active balancing go brrr though, great for just throwing in cells that aren’t exactly the same charge state. They use double pogo-pins for the balancing connection.

Questions are welcome.
