The JerryC battery pack add-on provides owners of the Jerry C5 and C2 a remote outboard battery option for extending battery life from 2 hours to 8 hours. Moving to outboard power also has the added benefit of reducing frontal helmet weight and increasing operator comfort over time.
The JerryC external battery pack comes with hook velcro that attaches directly to the back of the user's helmet and accommodates 2x 18650 batteries. An on-board power button enables or disables power from the pack and the pack can be separated from the helmet plate.
This is the same battery pack that comes with the Jerry CE5 and CE2.
