It replaces OEM part FD-CDM-A-L14.4 and restores power to the vacuum's motor and suction system. Capacity matches the original spec at 38.48Wh.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eT2, C1, D1, and M160 compatibility:\u003c\/strong\u003e\n    These four Elfbot models share the same 14.8V battery rail, connector pinout, and BMS handshake protocol — one pack serves all four without modification.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this pack through motor-start loads on the T2 platform. The BMS held steady through repeated start surges and responded correctly to the charger's handshake signal without throwing a fault.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eDock charging behaviour:\u003c\/strong\u003e\n    Do not leave the vacuum sitting on the charging dock between uses. Continuous dock connection exposes the cells to a slow trickle charge that accelerates capacity fade. Charge to full, then remove the vacuum from the dock until the next use.\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 T2's motor draws more current the moment airflow is restricted — a partially blocked filter or full dustbin forces the motor to work harder at the same voltage. As current draw climbs, cell voltage sags earlier in the discharge curve than the indicator expects, so suction weakens while the LED still shows two or three bars. This is not a battery fault — it's a load mismatch caused by restriction. Clean the filter and empty the dustbin before concluding the battery is weak.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eMotor cutting out mid-clean and recovering after a few seconds\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis is a BMS overcurrent trip. When the vacuum sustains restricted suction for more than a few seconds — hair wrap on the brush roll, blocked inlet, or clogged filter — current draw spikes past the BMS protection threshold and the pack shuts off to protect the cells. The BMS resets automatically after a short thermal and voltage recovery window, which is why power returns after a pause. Clear the blockage and restart the vacuum; the trip will not repeat if airflow is restored. If it trips repeatedly on an unblocked machine, check the brush roll for debris wrapped at the bearing ends.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43427987161178,"sku":"BWCS-ELT200VX-1","price":41.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43427987193946,"sku":"BWCS-ELT200VX-2","price":48.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43427987226714,"sku":"BWCS-ELT200VX-3","price":53.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-ELT200VX-1.webp?v=1779933799","url":"https:\/\/batteryweb.com\/products\/elfbot-t2-replacement-battery-148v-2600mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
