It replaces OEM part numbers D071-INR-CH-4S1P and 6.60.40.02-0. If your original pack no longer supports a full cleaning session on a single charge, this is the direct swap.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eXBOOST and BPK-VCBB1XB platform fit:\u003c\/strong\u003e\n    These models share the same 4S1P cell configuration, 14.4V nominal rail, and BMS handshake protocol. The connector and physical dimensions — 69.00 × 37.60 × 37.30mm — are identical across the listed variants, so the pack seats and locks without modification.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this pack through repeated motor-start and sustained-suction loads. The BMS held the 14.4V rail cleanly through blockage simulations and recovered without fault codes after overcurrent events during high-resistance carpet passes.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eDock charging habit on the XBOOST:\u003c\/strong\u003e\n    Do not leave the vacuum sitting on the charging dock between sessions. Continuous dock contact on this model keeps the BMS in a trickle state that accelerates capacity fade. Charge to full, remove from dock, and reconnect only when the pack is depleted.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eSuction dropping before the battery indicator reaches low\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe XBOOST motor draws significantly more current when the filter is partially blocked or the dust cup is near capacity. Under that extra load, a degraded cell can no longer hold the 14.4V rail steady, and the motor slows before the indicator registers a low battery. The vacuum appears to lose power prematurely, but the fault is voltage sag under load — not the indicator reading. A fresh 3400mAh pack restores the headroom needed to sustain motor speed through a full cleaning pass; clean the filter before fitting the new battery to avoid repeating the sag cycle immediately.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eMotor cuts out mid-use then recovers after a short pause\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis is a BMS overcurrent trip, not a mechanical fault. When suction is restricted — blocked nozzle, saturated filter, or dense carpet fibres — the motor pulls current above the BMS threshold and the pack shuts the output rail to protect the cells. After the BMS resets (typically within 20–30 seconds), the vacuum powers back on as if nothing happened. Clear the blockage or clean the filter first; if the cutouts continue with an unobstructed airway, the original pack's cells have degraded to where normal motor-start current is enough to trigger the trip. Replacing the pack resolves it — confirm the new pack reads at least 16.0V fully charged before first use.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43427964682330,"sku":"BWCS-LTR320VX-1","price":49.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43427964715098,"sku":"BWCS-LTR320VX-2","price":58.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43427964747866,"sku":"BWCS-LTR320VX-3","price":64.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-LTR320VX-1.webp?v=1779933588","url":"https:\/\/batteryweb.com\/products\/blaupunkt-xboost-replacement-battery-144v-3400mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
