The titanium TROLL Battery Pack supplements internal battery power for frequent fast sampling or long-term deployments with an Aqua TROLL 100/200, BaroTROLL, or Level TROLL 300/400/500/700.
When the battery pack is connected, the device uses the external battery source first, switching to the internal battery once external battery power is depleted. Communications pass through the battery pack.
