The SJ4000 Battery can also be used in the Gitup Git2 Action Camera but not the other way around.
The Old SJ4000 Battery is a bit loose in the Git2 battery compartment but does work OK.
P.S. The battery from the Git2, is too large and won't sit into the SJ4000 battery compartment.
Available fromBanggood Gitup Git2 Pro Camera
