The Topcon BDC71 Lithium-Ion Battery Survey Kit (1037805-01-SURSK) delivers dependable, full-shift power for professional-grade surveying instruments on demanding jobsites. Engineered specifically for Topcon total stations, robotic positioning systems, and GPS receivers, this survey kit bundles the high-capacity BDC71 battery with the accessories needed to keep your instruments running from first stake to final shot — without scrambling for a charge mid-day.
Overview & Jobsite Applications
Survey crews and construction layout teams depend on instrument uptime. The BDC71 Survey Kit is built around that reality. Lithium-ion chemistry maintains consistent output voltage across the full discharge cycle, so your instrument performs the same at 10% charge as it does at 100%. Whether you're running a robotic total station through a full day of machine control layout, cycling a GPS receiver across multiple control points, or using a conventional total station for boundary surveys, this kit ensures you're not the bottleneck on the job.
