7xAA battery holder with snap lid and integrated springs

This is a 7x AA parallel battery holder for larger currents. It has a snap lid, internal springs for the battery connectors and separated space for the wiring. It can be fitted a standard 1.5 mm2 7x0.5mm copper wire normally used in household electrical power (the one drawn inside the walls, therefore the 7x battery configuration...)

It can of course be modified to serial or any other configuration.

I intended to use this for a (not yet finalized by any means) robot lawn mover.
