It powers the drive motors, brush roll, and onboard navigation system. When the original cell degrades, this replacement restores the vacuum to full operating voltage.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eSRV 6110BK compatibility:\u003c\/strong\u003e\n    The SRV 6110BK uses a 14.4V pack with a specific BMS handshake that controls motor start current and low-voltage cutoff. Replacement cells carrying OEM part numbers LI-022148-BYD, BYD-F1, 4UR18650A-26, or 4UR18650A-26-V2 match that pack configuration exactly — same connector, same BMS signal, same charge termination logic.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this pack through sustained motor loads on a SRV-series unit and monitored BMS behaviour across multiple discharge curves. The protection circuit held cutoff at the correct low-voltage threshold and did not trip under normal carpet suction draw.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eDock charging habit on the SRV 6110BK:\u003c\/strong\u003e\n    Do not leave the SRV 6110BK sitting on the dock permanently between cleans. Robot vacuums on continuous dock charge trickle-charge the cell indefinitely, which degrades capacity faster than normal cycling. Charge to full, then lift the unit off the dock until the next scheduled clean.\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 SRV 6110BK\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe SRV 6110BK's brush motor draws significantly more current when the filter is partially blocked or the brush roll is tangled — more than it does on a clear hard floor. That extra draw causes voltage to sag at the cell level before the onboard indicator registers a low charge. The vacuum loses suction not because the battery is depleted, but because the BMS is limiting output current to protect the cell under that sustained load. Clearing the filter and brush roll before each run reduces peak draw and keeps the pack operating in its stable voltage range.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eMotor cuts out mid-clean then recovers after a few seconds\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis is a BMS overcurrent trip, not a battery failure. When the SRV 6110BK drives across thick carpet or encounters a restricted airway, the motor pulls a short burst of current above the pack's protection threshold — the BMS disconnects output, the motor stops, and the circuit resets within seconds. The fix is to check the filter first: a partially clogged filter forces the motor to work harder on every pass. Clean the filter, then run a charge cycle to bring the pack back to a stable resting voltage above 15.8V before resuming.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43426477867098,"sku":"BWCS-RBR200VX-1","price":48.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43426477899866,"sku":"BWCS-RBR200VX-2","price":57.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43426477932634,"sku":"BWCS-RBR200VX-3","price":63.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-RBR200VX-1.webp?v=1779933389","url":"https:\/\/batteryweb.com\/products\/sencor-srv-6110bk-replacement-battery-144v-2600mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
