It fits the Bot X30 Ultra, L10s Ultra Gen2, and RLL32SE among others. Voltage and cell configuration match the original P2150-4S2P-KLYEV and P2150-4S2P-SCEV OEM part numbers.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eMulti-model fit — L10s Ultra Gen2 platform:\u003c\/strong\u003e\n    These models share a 14.4V 4S cell architecture, the same physical connector, and an identical BMS handshake protocol. Swapping the pack does not require firmware changes or physical modification.\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 Bot L10s Ultra Gen2 dock. The BMS negotiated correctly with the charger, cell balancing engaged at the top of charge, and overcurrent protection tripped as expected under load.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eDock charging habit for this robot vacuum:\u003c\/strong\u003e\n    Do not leave the vacuum on the dock between cleaning sessions indefinitely. Continuous dock charging delivers a low-level trickle current once full, which accelerates capacity loss in Li-ion packs over weeks. Charge fully, then remove from dock until the next session.\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 rated current threshold allows under restricted airflow. A partially blocked filter or brush roll forces the motor to work harder, spiking current draw and triggering a soft voltage sag. The robot reduces suction power as a protective response rather than a battery failure. Clean the HEPA filter and check the brush roll before concluding the battery is at fault.\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 dead cell. When sustained suction restriction pushes current past the pack's cutoff threshold, the BMS disconnects the output to protect the cells. After a brief recovery window, it reconnects and the motor restarts. The fix is to clear the blockage or replace a clogged filter — once airflow is restored, current draw drops back within the BMS's safe operating window and the cutouts stop.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43426421014618,"sku":"BWCS-DRL200VX-1","price":78.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43426421047386,"sku":"BWCS-DRL200VX-2","price":92.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43426421080154,"sku":"BWCS-DRL200VX-3","price":102.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-DRL200VX-1.webp?v=1779933161","url":"https:\/\/batteryweb.com\/products\/dreame-bot-l10s-ultra-gen2-replacement-battery-144v-5200mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
