It fits the Intuvia Display, Intuvia E, Performance Line CX, and BDU3XX series e-bike display systems. The AHB502030 cell powers the display screen and wireless communication between the display and the drive unit.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eIntuvia and BDU3XX platform compatibility:\u003c\/strong\u003e\n    These display units share the same compact 3.7V cell pocket, connector pinout, and BMS communication protocol across the Intuvia E and Performance Line CX variants — one cell covers the full BDU3XX display family.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this cell through charge and wake cycles on a BDU3XX display. The BMS accepted the new pack without fault codes, the display initialised correctly, and voltage held stable at 3.7V under combined screen and radio draw.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-wake cycle on Bosch display units:\u003c\/strong\u003e\n    After fitting, leave the display connected to the e-bike system for a full charge cycle before riding. The BDU3XX controller logs the new cell state during this cycle — skipping it can cause the battery indicator to read inaccurately for the first several rides.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy the Intuvia display goes blank mid-ride on a new battery\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe Intuvia display draws current for both the screen backlight and the Bluetooth or ANT+ radio simultaneously. On a depleted or partially conditioned cell, that combined draw causes a brief voltage sag below the BMS cutoff threshold. The display shuts off as a protection event, not a connection fault. A full initial charge cycle stabilises the cell and raises the cutoff headroom enough to handle the combined load without dropout.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBattery indicator frozen or showing wrong level after replacement\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe BDU3XX system stores the previous cell's state-of-charge history in the drive unit controller. When a new cell is fitted at storage voltage — typically around 3.6V — the controller maps that reading against the old cell's profile and displays an incorrect level. Ride through two to three full charge and discharge cycles to let the controller recalibrate its fuel gauge against the new cell. After three cycles the indicator should track accurately from 3.7V full charge down to the low-voltage warning threshold.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43428115087450,"sku":"BWCS-BDU300SL-1","price":22.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43428115120218,"sku":"BWCS-BDU300SL-2","price":25.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43428115152986,"sku":"BWCS-BDU300SL-3","price":27.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-BDU300SL-1.webp?v=1779934164","url":"https:\/\/batteryweb.com\/products\/bosch-intuvia-display-replacement-battery-37v-250mah-li-polymer","provider":"BatteryWeb","version":"1.0","type":"link"}
