It replaces OEM part numbers 260MX2, 260S-INR-MH1-4S1P, and D099-4S2P. Compatible models include the MJST1S, MJST1S 2 Pro, MJST1SHW, and MJSTS.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eMJST1S family compatibility:\u003c\/strong\u003e\n    These models share the same 14.8V four-cell lithium architecture, connector pinout, and BMS communication protocol. Swapping within this family does not require firmware changes or tool modifications.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this battery through sustained suction loads on a restricted-filter rig. The BMS held cutoff at the correct undervoltage threshold and recovered cleanly after rest, with no false overcurrent trips on motor start.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eDock charging behaviour on the MJST1S:\u003c\/strong\u003e\n    Remove the vacuum from the charging dock once the indicator shows full. The MJST1S dock does not terminate charge aggressively — leaving the battery seated for days at a time accelerates capacity fade faster than normal cycling would.\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\"\u003eThe MJST1S motor draws significantly more current when airflow is restricted — a partially blocked filter can push draw above the BMS current threshold before the battery is genuinely depleted. The BMS reads this spike as low voltage under load and begins throttling motor speed. The battery indicator still shows charge because resting voltage is adequate. Clean or replace the HEPA filter first, then test — suction should hold steady to near the end of the charge cycle.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eMotor cutting out mid-clean and then recovering after a few seconds\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis is a BMS overcurrent trip, not a dead battery. When the vacuum hits a carpet obstruction or a heavily clogged filter, the motor labours and draws a sustained current spike. The BMS cuts power to protect the cells, then resets after a brief cooldown. If this happens repeatedly, check the filter and brush roll for blockage before assuming the battery is faulty. A clear airpath brings draw back within the 14.8V system's rated current envelope and stops the trips.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43427980345434,"sku":"BWCS-XMT200VX-1","price":65.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43427980378202,"sku":"BWCS-XMT200VX-2","price":77.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43427980410970,"sku":"BWCS-XMT200VX-3","price":86.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-XMT200VX-1.webp?v=1779933697","url":"https:\/\/batteryweb.com\/products\/xiaomi-mjst1s-replacement-battery-148v-3000mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
