Question from Marben Silva - 16/11/2018
- Hi, i have the Olight H2r Nova and i want to buy an extra battery. Is this the only 18650 compatible with the H2R? Or Can i get other olight 18650 batteries?
OLIGHT answer:
H2R requires the battery can have a discharging current of 8A . if the 18650 battery doesn’t have such big discharging current, the light can’t be turn to Turbo . And if you use your any other 18650 battery, you can’t charge the battery via the light.
