All V300 security cameras come with a Lithium battery pack (V-LIT-B3) that is included in the package. It has a built-in solar panel that acts as an alternate power source. 

• When using the battery pack for the first time, make sure to charge it for 24 hours before putting it into the camera. Use the provided charging cable and a standard USB charger to charge the battery every time. 
• Make sure to place the camera in an area where the solar panel can get enough sunlight. This will help maximize the battery life of your camera. 
• You may also directly power the camera using a USB-C cable and a power source that supports 5V/3A. For the best-wired performance please use the V-UC5V accessory (sold separately). 

Note: You cannot recharge the battery pack, V-LIT-B3 when it is inside the camera. Make sure to take the battery pack out and charge it separately.
