If someone happens to love the usb charging and have an S30R III, its battery (ORB-186C35, 3500 mAh) works well and has protection. It doesn’t sacrifice any lumens either. The S2R battery (ORB-186C32, 3200 mAh) on the other hand trips at 5 amps and doesn’t work on turbo on the H2R.
Still, just ditch the charging system and use a good regular cell…
