It uses an INR18650-4S2P cell configuration — four cells in series, two in parallel — matching the original pack's voltage rail and physical form factor. Capacity is 2600mAh (37.44Wh) as rated by the manufacturer.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eMOP8100 and MOP8400 compatibility:\u003c\/strong\u003e\n    Both models run the same 14.4V architecture and share the INR18650-4S2P pack format. The connector pinout and BMS handshake protocol are identical across the two, so one pack covers both units without modification.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this pack under simulated vacuum motor load and confirmed the BMS holds the charge correctly across full discharge and recharge cycles. The protection circuit responds to overcurrent conditions and resets cleanly without manual intervention.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eDock charging habit on the MOP8100:\u003c\/strong\u003e\n    Do not leave this vacuum sitting on the dock indefinitely between uses. Cordless vacuums on continuous dock charge develop capacity fade faster than units charged only when depleted. 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 reaches low\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis is a voltage sag issue, not a capacity issue. When the motor is working harder — dense carpet, a partly blocked filter, or a tangled brush roll — it draws more current than the pack's steady-state rating. Voltage at the motor drops under that load even though the battery still shows charge. The fix is to clean the filter first, because a restricted airflow path forces the motor to pull harder and triggers the sag earlier in the discharge cycle.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eMotor cutting out mid-clean then recovering after a short pause\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis is a BMS overcurrent trip, not a faulty battery. When sustained suction restriction pushes current draw past the BMS threshold — usually from a clogged filter or blocked inlet — the protection circuit cuts power to the motor. Waiting 30–60 seconds lets the BMS reset and the vacuum restarts normally. Clear the blockage and check that the filter is seated correctly before resuming; if the trip recurs on a clean filter, measure pack voltage under load — it should hold above 12.0V during normal operation.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43426414067802,"sku":"BWCS-BMP840VX-1","price":49.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43426414100570,"sku":"BWCS-BMP840VX-2","price":58.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43426414133338,"sku":"BWCS-BMP840VX-3","price":64.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-BMP840VX-1.webp?v=1779933186","url":"https:\/\/batteryweb.com\/products\/bobot-mop8100-replacement-battery-144v-2600mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
