Soloshot extra battery holder

I was tired for base battery to run out of power so many times, and I need the system to be on a high tripod, so some of the solutions proposed in this forum didn't work for me, so I created this
Its a cradle that hosts a battery bank, can be removable and the battery can be replaced. So my idea is to have 2-3 battery banks in hand so I can swap them as needed.
