The ABAM (ANVIS Battey Adapter Module) is an easy way to use the GBS or NVAG-9 without the standard battery pack. It gives the user the freedom to remove the goggle from the helmet and use it as a hand-held night vision device. The ABAM powers the GBS or NVAG-9 with a single CR-123 lithium battery and is designed with a simple push-button ON/OFF operation.
