It slots in where the original pack sits and restores full motor voltage to the suction unit. No OEM part number is published for this model, but the cell spec and connector match the SR2000 and SR2001 battery bay directly.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eSR2000 and SR2001 compatibility:\u003c\/strong\u003e\n    Both models run the same 10.8V motor rail and use the same battery housing dimensions and contact layout, so one cell covers the pair. The BMS in this pack communicates discharge cutoff at the same voltage threshold the vacuum's motor controller expects.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran the pack through charge and discharge cycles on the SR2000 motor unit. The BMS held steady across repeated suction loads and triggered low-voltage cutoff cleanly without causing the motor to stall mid-cycle.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eDock charging on the SR2000:\u003c\/strong\u003e\n    Remove this battery from the charging dock once the indicator shows full. The SR2000 dock does not step down to a maintenance charge — it continues delivering current, which accelerates capacity fade in Li-ion cells faster than periodic full charges do.\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 draws more current than the BMS is rated to supply continuously — usually caused by a partially blocked filter, not a weak battery. A restricted airpath forces the motor to work harder, pulling higher current and triggering the BMS to throttle output voltage before the cell is actually depleted. Clean or replace the filter first. If suction recovers immediately after filter cleaning, the battery was never the issue.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eMotor cuts out mid-use and then recovers after a short pause\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis is a BMS overcurrent trip, not a dead cell. When the SR2000 motor runs against a sustained blockage or heavy carpet load, current draw spikes above the pack's overcurrent threshold and the BMS shuts output off to protect the cells. The pack resets itself after a brief cooldown, which is why the vacuum works again after you set it down for 30–60 seconds. Clear any blockage in the nozzle or hose, then check that the filter is clean before resuming use.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43428001284186,"sku":"BWCS-MDH161VX-1","price":33.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43428001316954,"sku":"BWCS-MDH161VX-2","price":38.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43428001349722,"sku":"BWCS-MDH161VX-3","price":42.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-MDH161VX-1.webp?v=1779933799","url":"https:\/\/batteryweb.com\/products\/evolution-sr2000-replacement-battery-108v-2600mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
