Battery: 18650 Battery - 3500mAh 3.7V

We use 3,500mAh capacity 3.7V 18650 batteries with overpower protection.  Most other dive lights use generic batteries that have a capacity of 2200 - 2600mAh.  That means our batteries have up to 37% more capacity.  

Capacity : 3500mAh 

Nominal Voltage: 3.7V

Peak Voltage: 4.2V

Protected: Yes


Protected batteries have a small circuit board integrated into the cell that protects the battery against common dangers such as overcharge, over discharge, short circuit and excess current.  Protected batteries are safer to use and ensure the battery isn't damaged through over discharging.
