A converter for a rechargeable battery (e.g., lithium battery) is disclosed. In some embodiments, the converter includes a direct current (DC) to DC converter and a microcontroller unit (MCU). The DC to DC converter includes a switching circuit configured to generate a pulse width modulated (PWM) voltage from the rechargeable battery voltage, wherein the switching circuit is configured to set a variable duty cycle of the PWM voltage. The DC to DC converter also includes a filtering circuit configured to convert the PWM voltage into a DC output voltage having an output voltage level that is set in accordance with the variable duty cycle of the PWM voltage. The MCU is configured to adjust the variable duty cycle of the switching circuit such that the output voltage level of the DC output voltage emulates a discharge voltage curve of a dry battery while the rechargeable battery is being discharged.

Various embodiments herein provide a headlamp with a light unit, a battery unit, and a booster unit. The booster unit includes an engagement mechanism (e.g., a bar, such as a U-shaped bar) that mechanically couples the booster unit to the battery unit to provide additional power. The engagement mechanism may further form a clip to couple the booster unit to another item when the booster unit is not coupled to the battery unit. The booster unit may include one or more lights, one or more controls for the one or more lights, and/or an outgoing power port to provide power to another device (other than the battery unit and light unit). Other embodiments may be described and claimed.
