i-Seis Sigma Battery Box Charging Strips

The GSL charging strips are able to charge up to twelve Sigma Battery Boxes concurrently in one go and are extremely low maintenance. Each charging port comes with a protective screw-on dust cap to keep out unwanted dust, sand, dirt or other undesirable particles from getting inside. Each charging port is sturdy and secure, ensuring zero chances for short circuits occurring accidentally while you screw in a Sigma Battery Box. Charging strips can be operated in any orientation and the current model only accommodates charging ports on one side. Each charging strip also comes with a mounting hole, giving you the flexibility to place them on walls or suspended them off the ground.

Available now at US$500.00 per strip.
