INNO DS8000B 11.1V Compatible Battery 6700mAh Li-ion

INNO DS8000B — 11.1V Li-ion Replacement Battery

This is a 11.1V, 6700mAh (74.37Wh) Li-ion battery for the INNO DS8000B GPS surveying instrument. It slots into the DS8000B's battery bay and powers the receiver through extended field sessions. No OEM part number is publicly listed for this pack.

• DS8000B compatibility: The DS8000B runs a fixed 11.1V three-cell Li-ion architecture. This pack matches that voltage rail exactly. The BMS communicates state-of-charge to the instrument's power management circuit — a voltage or cell-count mismatch would cause the instrument to reject the pack or report incorrect charge levels.
• Bench tested on actual hardware: We cycled this pack through the DS8000B's satellite acquisition and continuous logging load. The BMS handled the initialisation current draw at startup without tripping, and cell balance held within tolerance across the discharge curve.
• First-use calibration cycle: After installing, run a full calibration cycle through the DS8000B's instrument menu before field deployment. The instrument maps battery state during calibration — skipping this step causes premature low-battery warnings during your first measurement session, even when the pack is fully charged.

BMS cutoff during satellite acquisition on the DS8000B

When the DS8000B initialises its GNSS module, it draws a short current spike as the receiver locks onto satellites and the antenna circuit powers up. On a degraded or cold pack, this spike can push the draw past the BMS overcurrent threshold, causing an immediate shutdown. This looks like the instrument turning off seconds after boot — not a hardware fault. Warming the pack to above 10°C before powering on reduces cell internal resistance and keeps the startup draw within BMS limits.

DS8000B shows full charge on screen but shuts down under logging load

This happens when the instrument's charge indicator calibrates against a resting cell voltage rather than a loaded one. Under sustained GNSS logging, combined draw from the receiver, onboard storage, and RTK radio causes voltage to sag below the instrument's cutoff threshold — even though the display showed a healthy percentage moments before. The fix is to run the calibration cycle after installing a new pack so the instrument re-maps its voltage thresholds against actual load conditions. If the shutdowns continue, check that cell voltage at the pack terminals reads above 10.5V under load with a multimeter.
