Note: Runtime is measured using one 3600mAh high discharge 18650 li-ion batteries. HIGH level runtime includes out-of-current regulation time period when battery is almost depleted. With active thermal management feature, runtime in cooler environment will have shorter runtime, and long runtime in hotter environment.
