It fits the S1 platform directly, restoring motor voltage to specification. Capacity matches the original at 2200mAh (24.42Wh).\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eS1 platform fit:\u003c\/strong\u003e\n    The S1 series runs a single battery configuration across handheld and stick use. Voltage rail, connector pinout, and BMS handshake are consistent across S1 units, so one replacement covers both listed model variants.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this cell through the S1 motor under load. The BMS held voltage above the cutoff floor under sustained suction draws, and overcurrent protection tripped correctly when airflow was restricted — then reset cleanly once the blockage cleared.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eDock charging behaviour on the S1:\u003c\/strong\u003e\n    Do not leave the S1 sitting on the charging dock indefinitely. Continuous trickle charging degrades Li-ion cell capacity faster than normal cycling. Charge to full, then remove from the dock until the next use.\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\n  \u003cp class=\"bpw-desc-p\"\u003eThis happens when the motor draws more current than the cell can sustain at the current state of charge. Voltage sags under load before the indicator registers a low-battery condition, so the vacuum feels like it's losing power while the LED still shows adequate charge. A partially blocked filter makes this worse — restricted airflow forces the motor to work harder, pulling higher current and amplifying the sag. Clean the filter first, then check whether the issue persists; if it does, the cell can no longer hold voltage under load and needs replacing.\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\n  \u003cp class=\"bpw-desc-p\"\u003eThis is a BMS overcurrent trip, not a dead battery. When airflow restriction spikes current draw beyond the BMS threshold — usually from a clogged filter or a blockage at the nozzle — the protection circuit opens and the motor stops. The BMS resets automatically once current drops, which is why power returns after a short pause. Clear the filter and check the nozzle path for debris before assuming the battery is at fault; a clean airway keeps current draw inside the BMS operating window.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43426409021530,"sku":"BWCS-PCM100VX-1","price":73.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43426409054298,"sku":"BWCS-PCM100VX-2","price":87.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43426409087066,"sku":"BWCS-PCM100VX-3","price":97.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-PCM100VX-1.webp?v=1779933117","url":"https:\/\/batteryweb.com\/products\/proscenic-s1-replacement-battery-111v-2200mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
