It fits the Liectroux C30B, C30B 2D, C30B 2D Wifi Robot Vacuum Cleaner, and E30. When the original pack loses the voltage headroom to complete a full cleaning cycle, this replacement restores it.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eC30B and E30 platform compatibility:\u003c\/strong\u003e\n    These models share the same 14.4V power rail, connector pinout, and BMS handshake protocol. A single cell specification covers all listed variants without modification.\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 a C30B unit. The BMS engaged overcurrent protection correctly under a simulated motor blockage and reset cleanly once load was removed.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eDock charging habit on the C30B:\u003c\/strong\u003e\n    Do not leave the C30B sitting on its charging dock permanently. Continuous trickle charging degrades Li-ion cell capacity significantly faster than charge-and-remove cycles. Charge to full, then lift the unit off the dock until the next run.\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\n  \u003cp class=\"bpw-desc-p\"\u003eThis happens when the motor draws more current than the BMS expects — usually because the filter is partially blocked. A restricted airflow path forces the motor to work harder, pulling higher amps and triggering a soft voltage sag at the cell level. The robot interprets that sag as reduced charge, so the indicator reads mid-range while suction has already fallen. Clean or replace the filter first, then retest. If the problem persists on a fresh filter, the original battery pack has likely reached end of cell life.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eMotor cutting out mid-cycle and then recovering on its own\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis is a BMS overcurrent trip — not a permanent fault. When the robot hits a carpet edge, a large debris piece, or a partial blockage, the motor draws a short spike of current above the BMS threshold. The BMS disconnects to protect the cells, then resets once load drops. If this happens repeatedly, check for a blocked brush roll or a clogged filter before assuming the battery is faulty. A healthy pack on this platform should sustain motor-start current without tripping; if trips continue on a clear machine, verify the pack is reading 14.4V fully charged before investigating further.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43427998335066,"sku":"BWCS-LTR300VX-1","price":43.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43427998367834,"sku":"BWCS-LTR300VX-2","price":51.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43427998400602,"sku":"BWCS-LTR300VX-3","price":56.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-LTR300VX_1.webp?v=1779933800","url":"https:\/\/batteryweb.com\/products\/liectroux-c30b-replacement-battery-144v-2600mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
