Blaupunkt XTREME 14.4V Cordless Vacuum Replacement Battery 6700mAh

Blaupunkt XTREME Series — 14.4V Li-ion Replacement Battery (6.60.40.01-0)

This is a 14.4V 6700mAh lithium-ion battery pack for the Blaupunkt XTREME cordless vacuum cleaner range. It fits the BPK-VCBB1XTE, BPK-VCBB1XTEIC, and BPK-VCBB1XTEN models using OEM part number 6.60.40.01-0. The pack slots directly into the original battery bay and communicates with the vacuum's power management circuit.

• XTREME model compatibility: The BPK-VCBB1XTE, BPK-VCBB1XTEIC, and BPK-VCBB1XTEN variants share the same 14.4V battery rail, connector pinout, and BMS handshake protocol — which is why a single pack covers all three.
• Bench tested on actual hardware: We cycled this pack through discharge under sustained motor load. The BMS held the 14.4V nominal rail cleanly and triggered low-voltage cutoff at the expected threshold without nuisance trips during normal suction cycles.
• Dock charging habit: Do not leave the XTREME sitting on the charging dock continuously. Cordless vacuums on permanent dock charge develop capacity fade significantly faster than units charged only when depleted. Charge to full, then remove the battery or unplug the dock.

Suction dropping before the battery indicator reaches low

The XTREME motor draws more current when airflow is restricted — a partially blocked filter forces the motor to work harder than its rated load. Under that extra draw, cell voltage sags faster than the indicator tracks, so suction weakens while the LED still shows adequate charge. The BMS reads actual cell voltage, not the indicator's averaged estimate. Clean or replace the filter first — if suction restores immediately, the battery was not the fault.

Motor cutting out mid-clean and recovering after a short pause

This is a BMS overcurrent trip, not a dead battery. When the motor sustains a restricted draw — typically from a blocked filter or a jammed brush roll — current spikes past the pack's protection threshold and the BMS disconnects the output. After a brief rest, cell temperature drops and the BMS resets, which is why the vacuum comes back on. Clear the blockage and check the filter before replacing the pack. If the trip repeats on an unobstructed machine, measure pack voltage under load — it should hold above 13.0V during normal motor start.
