It powers the SN500's drive motors and navigation systems. Swap it in when the original cell has degraded and cleaning cycles are cutting short.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eSN500 platform fit:\u003c\/strong\u003e\n    The SN500 uses a 14.8V four-cell Li-ion pack with a specific connector and BMS communication line. This battery matches that voltage rail and connector, so the vacuum's charge controller can read cell state correctly.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this cell through charge and discharge cycles on the SN500 platform. The BMS handled motor-start current draw without tripping, and the charge controller accepted the handshake on first connection.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eDock charging habit on the SN500:\u003c\/strong\u003e\n    Do not leave the SN500 sitting on the dock between uses. Continuous trickle charging degrades Li-ion cells faster than normal cycle use. Charge the vacuum to full, then remove it from the dock until the next 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\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis happens when the motor is working harder than rated — usually because a partially blocked filter forces it to pull more current to maintain airflow. The battery voltage sags under that extra load, and the SN500's motor controller backs off power before the battery gauge registers a low state. The indicator reads mid-charge, but the cell is already under stress. Clean the filter first, then retest — if suction holds steady, the battery is not the cause.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eMotor cuts out mid-cycle then restarts on its own\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis is a BMS overcurrent trip, not a flat battery. When suction is restricted — blocked filter, tangled brush roll, or carpet fibres jamming the intake — current draw spikes beyond what the BMS allows. The BMS cuts the output to protect the cells, then resets after a few seconds. The fix is to clear the restriction, not replace the battery. If the cut-outs continue after cleaning the filter and brush roll, check the intake path for a partial blockage and verify the replacement cell's BMS trip threshold sits at or above 5A continuous draw.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43428014096474,"sku":"BWCS-MVS500VX-1","price":37.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43428014129242,"sku":"BWCS-MVS500VX-2","price":43.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43428014162010,"sku":"BWCS-MVS500VX-3","price":48.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-MVS500VX-1.webp?v=1779933850","url":"https:\/\/batteryweb.com\/products\/myvacbot-sn500-replacement-battery-148v-2600mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
