It connects to the battery's charging port or junction box and draws power from any USB-A source — a laptop, wall adapter, or portable battery bank — charging a depleted battery in approximately 1.5 hours, with an LED indicator confirming status and full charge. Note: this charger is not compatible with the wireless BT-DN300 battery used in 12-speed R9200 Dura-Ace, R8100 Ultegra, and XTR M9250 systems, which require the EW-EC300 adapter instead.\u003c\/p\u003e\u003cp\u003eBeyond charging, the SM-BCR2 doubles as the PC linkage device for Shimano's E-Tube Project software on Windows. Plugging it into a computer unlocks firmware updates across all connected Di2 components, shift button remapping, multi-shift speed adjustment, and system diagnostics — functionality that would otherwise require a professional service visit.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eCharges BT-DN110 and SM-BTR2 Di2 internal batteries via USB-A connection\u003c\/li\u003e\n\u003cli\u003eCompatible with 11-speed Dura-Ace 9070\/9150, Ultegra 6770\/6870\/8050\/8070, and Alfine Di2 systems\u003c\/li\u003e\n\u003cli\u003eNot compatible with 12-speed wireless BT-DN300 battery systems\u003c\/li\u003e\n\u003cli\u003eApproximately 1.5-hour full charge time with LED status indicator\u003c\/li\u003e\n\u003cli\u003eFunctions as PC linkage device for E-Tube Project firmware updates and customization\u003c\/li\u003e\n\u003cli\u003eEnables shift button remapping, multi-shift tuning, and component diagnostics\u003c\/li\u003e\n\u003cli\u003eWindows drivers required for E-Tube Project PC connection\u003c\/li\u003e\n\u003cli\u003eUSB-A cable included for use with laptops, wall adapters, or battery banks\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SHIMANO","offers":[{"title":"Default Title","offer_id":46078016192581,"sku":"689228725621","price":160.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0714\/0032\/5189\/files\/112354-1.jpg?v=1792571256","url":"https:\/\/noboundoriosssport.shop\/products\/shimano-di2-battery-charger","provider":"No Boundaries Sport","version":"1.0","type":"link"}
