It replaces OEM part number LB01, which powers the DL880's motor and suction system. Fits the DL880 handheld unit directly.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eDL880 motor platform:\u003c\/strong\u003e\n    The DL880 runs a direct-drive suction motor on a 14.8V four-cell Li-ion pack. The LB01 form factor and BMS handshake match this platform — the charger communicates with the pack's protection circuit before initiating charge current.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this pack through the DL880's charge and discharge sequence. The BMS held the cell group voltage within spec under sustained motor load, and the over-current protection tripped correctly when we simulated a blocked airway restriction.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eDock charge behaviour on the DL880:\u003c\/strong\u003e\n    Do not leave the DL880 on the charging dock permanently. Continuous dock charging passes a low-level trickle current into the cells even after full charge is reached. This accelerates capacity fade faster than normal cycle wear. Charge to full, then remove the vacuum from the dock.\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 on the DL880\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis happens because the DL880 motor draws more current when airflow is restricted — a partially blocked filter forces the motor to work harder than its rated draw. Under that elevated load, cell voltage sags earlier than the indicator circuit expects, so suction weakens while the LED still shows a mid-charge state. The BMS reads actual cell voltage, not the indicator logic, so it may reduce output before the display catches up. Clean or replace the filter first, then retest — if suction holds steady, the battery is not the cause.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eMotor cuts out briefly then recovers during a cleaning pass\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis is a BMS overcurrent trip. When the suction path is blocked — by a full dust cup, clogged filter, or a foreign object partially lodged in the nozzle — airflow restriction causes motor current to spike above the BMS threshold. The protection circuit cuts power for a few seconds, then resets. It is a protection event, not a battery fault. Empty the dust cup, clean the filter, and clear the nozzle path before concluding the battery has failed. If the cutout persists with a clear airway, check that cell voltage at rest is above 14.0V.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43428012392538,"sku":"BWCS-DKL880VX-1","price":41.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43428012425306,"sku":"BWCS-DKL880VX-2","price":48.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43428012458074,"sku":"BWCS-DKL880VX-3","price":53.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-DKL880VX-1.webp?v=1779933824","url":"https:\/\/batteryweb.com\/products\/donkey-dl880-replacement-battery-148v-2600mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
