FARO Focus3D Replacement Battery 14.4V 6750mAh Li-ion

FARO Focus3D X 130 / X 330 & Core Max — 14.4V Li-ion Replacement Battery (ACCS-PWR-0014)

This 14.4V 6750mAh (97.2Wh) Li-ion battery replaces the OEM pack in the FARO Focus3D X 130, Focus3D X 330, and Core Max 3D laser scanners. It fits the battery bay and matches the connector and BMS handshake protocol the scanner expects on power-up. Capacity and voltage are sourced from the original specification — not rounded or estimated.

• Focus3D X-series and Core Max compatibility: These models share the same 14.4V battery bay, connector pinout, and BMS communication protocol. The scanner reads cell state through a data line on boot — all three platforms use the same handshake sequence, which is why one pack covers the range.
• Bench tested on actual hardware: We cycled this pack through scanner power-up, full scan initialisation, and sustained sensor load. The BMS held stable across motor spin-up and laser activation without tripping the overcurrent threshold.
• Post-install calibration cycle: After fitting this battery, run a full calibration cycle through the scanner's system 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 at full charge.

BMS lockout after the Focus3D sits unused for months

Li-ion cells in survey instruments self-discharge during storage, and the FARO scanner's BMS will enter a protection lockout if cell voltage drops below roughly 2.5V per cell. At that point the pack will not respond to a normal charge cycle — the charger sees too low a voltage to initiate. To recover, use a charger with a recovery or "wake" mode that applies a low-current pre-charge at around 0.1C until cell voltage climbs back above 3.0V per cell. Once the BMS releases, a standard charge cycle completes normally.

Scanner shuts down mid-scan when the rotating head reaches full speed

The Focus3D's mirror motor draws a brief current spike as it accelerates to scanning speed — this is separate from the steady-state laser and sensor load. An aged or partially discharged pack can sag enough during that spike to cross the BMS undervoltage cutoff, and the scanner shuts off cleanly rather than corrupting scan data. This is not a firmware fault — it is the BMS protecting the cells. Charge the pack fully before the session, and if shutdowns persist on a new pack, check that the battery contacts in the bay are clean and making firm contact, as a resistive connection amplifies the voltage sag under load.
