“I bought this to have a 2nd battery with my vest (per recommendation from friends). Then I can still wear the vest while the other battery is charging. One thing that would be nice is to have another pocket on the inside of the vest (opposite the battery pocket) to be able to slide the backup battery into when not using/charging. The pocket could also be used to keep cards/cash on the inside of the vest if you’re not putting a battery in it since there are no other internal pockets.”
