How to charge the Battery for the WISPR Ranger Pro

NEVER charge a Lithium Polymer (LiPo) battery that is not rated for high voltage in LiHV mode. Charging a “standard” Lithium battery with a nominal voltage of 3.7V per cell in LiHV mode will over charge the battery, resulting in damage to the battery, fire, or an explosion.
