Why is it not possible to select higher modes when the HM75R is charged by the power extender?Updated 4 months ago

When using the power extender to charge the HM75R headlamp, the headlamp is charged indirectly, and the power extender is not capable of driving large currents. As a result, the actual brightness of each output depends on the charging voltage when the HM75R is charged by the power extender. Refer to detailed explanation.
