It fits the HT Multifunktionsgerat, HT Rohrbandschleifer, and PRO HT Winkelschleifer lines. Same voltage rail and connector format as the original pack.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eMulti-model fit across the HT platform:\u003c\/strong\u003e\n    These tools share an 18V architecture and a common battery interface, so one pack covers grinding, filing, and angle work without switching systems. The BMS handshake is consistent across the HT line.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this pack through motor-start inrush cycles on the HT Powerfeile and monitored BMS response. The overcurrent threshold held stable across repeated trigger pulls. No false cutoff was recorded during normal load cycling.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBreak-in load profile for the HT rotary file:\u003c\/strong\u003e\n    On first use, run the tool at half load for two cycles before full grinding pressure. This lets the BMS log the motor inrush pattern and calibrate overcurrent thresholds before heavy stock removal begins.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBMS cutoff on motor-start inrush in the HT Powerfeile\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe HT Powerfeile draws a sharp current spike the moment the trigger closes — this is normal motor-start inrush. A new pack with a cold BMS may not yet have a logged inrush profile, so it can trip the overcurrent protection prematurely. This is not a faulty battery. Running two light-load warm-up cycles allows the BMS to set a stable threshold matched to this motor's actual draw pattern.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eTool bogs and loses torque mid-grind — voltage sag under sustained load\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eIf the tool slows or weakens during extended metal shaping, the cause is usually voltage sag rather than cell failure. High contact resistance at the battery terminal rail drops the delivered voltage under load. Clean the terminal contacts on both the tool and the pack with isopropyl alcohol, then check that the pack seats fully — a partial connection increases resistance sharply. A healthy pack should hold above 16V at the terminal under load; below that, inspect the contact pins.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43416015143002,"sku":"BWCS-MTB180VX-1","price":79.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43416015175770,"sku":"BWCS-MTB180VX-2","price":92.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43416015208538,"sku":"BWCS-MTB180VX-3","price":102.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-MTB180VX-1.webp?v=1779759486","url":"https:\/\/batteryweb.com\/products\/eisenblatter-ht-powerfeile-replacement-battery-18v-2000mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
