It also fits the M6, M7 LDS, and M7 Max, along with several other models in the Proscenic lineup. Swap it in when the original cell no longer holds enough charge to complete a full cleaning cycle.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eMulti-model fit across the M-series platform:\u003c\/strong\u003e\n    The M6, M7 LDS, M7 Pro, and M7 Max all share the same 14.4V bus, connector pinout, and BMS handshake protocol — that's why one cell works across the range. The NR18650 M26-4S2P pack slots in without firmware or hardware changes.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this pack through full charge and discharge cycles on the M7 Pro platform. The BMS communicated correctly with the robot's charge controller, current limits held steady under simulated suction load, and the cell hit rated capacity within two cycles.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eDock charging discipline on robotic vacuums:\u003c\/strong\u003e\n    Do not leave the robot sitting on the dock between uses indefinitely. Continuous trickle charging degrades Li-ion cells faster than normal cycling. Charge to full, then remove from the dock — return it only when the battery is actually depleted.\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 the most common complaint on aging Proscenic M-series batteries and it's not always the battery's fault. A partially clogged filter forces the suction motor to draw more current than rated to maintain airflow. That extra draw causes voltage to sag under load, which the BMS reads as a low-cell condition and throttles power — even when the indicator still shows mid-charge. Clean the filter first. If suction recovers immediately after cleaning, the battery is not the cause. If the robot still throttles on a clean filter with a new cell under load, check that pack voltage under load stays above 12.8V.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eMotor cuts out mid-clean and then recovers after a few seconds\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis is a BMS overcurrent trip, not a dead battery. It happens when the suction path is partially blocked — a clump of debris, a tangled brush roll, or a clogged inlet — causing the motor to spike current beyond the BMS protection threshold. The BMS cuts power to protect the cells, waits for the fault to clear, then resets. Clear the blockage, check the brush roll for hair wrap, and confirm the filter is seated correctly. On a clean machine with a new battery, the BMS should not trip at all during normal carpet or hard-floor operation.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43427995549786,"sku":"BWCS-PCM710VX-1","price":70.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43427995582554,"sku":"BWCS-PCM710VX-2","price":83.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43427995615322,"sku":"BWCS-PCM710VX-3","price":92.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-PCM710VX-1.webp?v=1779933755","url":"https:\/\/batteryweb.com\/products\/proscenic-lds-m7-pro-replacement-battery-144v-5200mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
