RAPID DEPLOYMENT

SBB250 BATTERY BOX

DESCRIPTION

The SBB250 V2 is a supplementary battery box that extends the run time of the SRB250 rapid deployment repeater. This enhanced version is an evolution of the previous SBB250, specifically designed for prolonged operational scenarios, such as supporting communication during floods, bushfires, or other critical situations that necessitate several days of sustained battery power for the SRB250 repeater.
