Connecting batteries in show is necessary if power inverter, solar crossbreed inverter or UPS need an increase of power voltage working. As an example, an inverter designed for 24V battery packs need you to connect two 12V similar capability battery packs in series (2x12V = 24V). You can also hook up lower current Maintenance free, VRLA, Flooded lead acid or Lithium battery packs including with 24V inverter you’ll be able to hook up twelve 2V similar capability battery packs in series (12x2V = 24V) or four 6V close capacity battery packs in show with-it (4x6V=24V).
