4xAA Battery Holder

I used to photograph weddings and flash was an important part  of it. Weddings are a fast paced and high stress event for photographers.Last thing you want is to rummage around and find 20 batteries not knowing which are depleted and which are charged. My flash guns each use 4 AA batteries so I wanted to have groups of 4 in a holder, each with a charge indicator. Hence this design. In addition to the 4 parts all you need is a suitable length rubber band. The band is threaded through all components and hooks on the bottom and the indicator handle. On top there is an ‘OK’ and an ‘X’ to indicate charge state by rotating the indicator handle.
