INNO DS8000B Compatible Battery 11.1V 5200mAh Li-ion

INNO DS8000B — 11.1V Li-ion Replacement Battery

This is an 11.1V, 5200mAh (57.72Wh) Li-ion battery pack for the INNO DS8000B GNSS surveying instrument. It fits the DS8000B receiver used in land surveying, construction layout, and geospatial data collection. Voltage and form factor match the original pack exactly.

• DS8000B platform fit: The DS8000B runs its GNSS receiver, IMU, and radio modem off a single 11.1V rail. Any pack for this unit must meet that rail voltage and clear the instrument's BMS handshake — a mismatch on either causes the instrument to reject the pack at startup.
• Bench tested on actual hardware: We cycled this pack through GNSS acquisition, sustained satellite lock, and concurrent Bluetooth data output. The BMS held stable across all three loads without triggering an over-current cutoff or a low-voltage shutdown event.
• Post-storage initialisation for DS8000B: After installing, run a full calibration cycle through the instrument menu before field deployment. The DS8000B maps battery state during calibration — skipping this step causes premature low-battery warnings on the first measurement session, even with a fully charged pack.

Li-ion cells self-discharge during storage. If the DS8000B sits long enough, the pack voltage drops below the BMS recovery threshold — typically around 2.5V per cell, or roughly 7.5V across the 3S pack. At that point, the BMS enters a protection state and will not accept a charge from the instrument's cradle or standard charger. To recover the pack, use a charger with a trickle or recovery mode that can push a low-current charge at under 0.1C until cell voltage climbs above 3.0V per cell, then hand off to the standard charge cycle.

DS8000B readings drifting or session data resetting mid-log

During a sustained logging session, the DS8000B draws power continuously across the GNSS module, internal storage writes, and any active radio link. If the battery cells have aged or the pack voltage sags under combined load, the instrument can brown out briefly — enough to interrupt the logging process and corrupt or reset the active session. This is not a software fault. Check the pack's resting voltage before a long session — it should sit at or above 11.1V at rest. If the resting voltage reads below 10.5V after a full charge, the pack has degraded and needs replacement.
