It uses a 4S1P configuration — four 18650 cells wired in series — matching the original pack's voltage rail and connector layout. Capacity is 2600mAh as specified in the product data.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eR1 and R3-L101C compatibility:\u003c\/strong\u003e\n    Both models run the same 14.4V motor platform and share the INR18650-4S1P pack format. The connector, BMS handshake, and cell arrangement are identical across this vacuum line, so one pack fits either unit without modification.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this pack through charge and discharge cycles on the R1 platform. The BMS handled motor-start inrush current without tripping and held consistent voltage delivery through the full discharge curve.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eDock charging behaviour on the R1 and R3-L101C:\u003c\/strong\u003e\n    Do not leave the vacuum sitting on the charging dock continuously between uses. The R1 and R3-L101C docks do not fully terminate charge — cells see a low-level trickle that accelerates capacity fade. Charge to full, then remove 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 shows low on the R1\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis happens when the motor is working against a restriction — a clogged filter, packed dustbin, or partially blocked nozzle. The motor draws more current to maintain suction, which pulls the cell voltage down faster than normal. The BMS reads this voltage sag as a low-battery condition and begins throttling output before the indicator registers it. Clear the filter and empty the bin first — if suction restores, the pack is not the issue.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eMotor cutting out mid-clean and recovering after a short pause\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis is a BMS overcurrent trip, not a faulty pack. When suction is restricted — blocked filter, jammed brush roll, or sealed nozzle — the motor current spikes past the BMS protection threshold and the pack shuts off. A short pause lets the BMS reset, which is why the vacuum starts again seconds later. Fix the restriction first. If the motor cuts out on a clear nozzle with a fresh filter, check that the battery terminals are seating fully and the pack voltage at rest reads at least 14.0V.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43426404991066,"sku":"BWCS-MDR300VX-1","price":43.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43426405023834,"sku":"BWCS-MDR300VX-2","price":51.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43426405056602,"sku":"BWCS-MDR300VX-3","price":56.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-MDR300VX-1.webp?v=1779933117","url":"https:\/\/batteryweb.com\/products\/media-r1-replacement-battery-144v-2600mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
