It replaces the OEM QV43 battery when the original cell degrades, swells, or no longer holds a charge. Same voltage, same connector, same BMS communication protocol as the factory cell.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eQV43 platform compatibility:\u003c\/strong\u003e\n    The Moto Edge 50 Neo 5G, Moto S50 5G, and ThinkPhone 25 5G share the QV43 cell because they run the same power delivery architecture — same voltage rail, same flex connector layout, and the same fuel gauge IC handshake. Swapping across these models works without modification.\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 discharge cycles on the Edge 50 Neo 5G platform. The BMS accepted the cell without fault flags, USB-PD negotiation completed normally, and the charge IC held the correct 4.45V full-charge cutoff throughout.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFuel gauge recalibration on first use:\u003c\/strong\u003e\n    On first use after installation, disable fast charging for one complete discharge-charge cycle. The fuel gauge IC is calibrated to the old cell's discharge curve. Running one slow cycle lets the coulomb counter establish a new baseline before high-current fast charging pushes current into an uncalibrated cell.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eSudden shutdown at 20–30% on the replacement QV43 cell\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThis happens because the fuel gauge IC still references the discharge curve of the old, degraded cell. The new cell has a steeper voltage cliff at lower state-of-charge, so when the modem fires a high-current burst — during a call or 5G handoff — the voltage drops sharply and the IC reads it as a critical low. The phone cuts out even though capacity remains. One full slow discharge-charge cycle recalibrates the coulomb counter. After that cycle, shutdowns at 20–30% stop.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eUSB-PD fast charge not negotiating on first cycle after swap\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eOn first connection after installation, the Edge 50 Neo 5G may fall back to standard 5W charging rather than accepting the faster USB-PD or TurboPower protocol. The charge IC treats a new, high-impedance cell cautiously on the first cycle and limits current until it confirms cell stability. This is normal BMS behaviour — not a fault with the replacement cell. Complete one full charge at the lower rate, then disconnect and reconnect the charger. Fast charging resumes from the second cycle onward.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43391773737050,"sku":"BWCS-MTV430SL-1","price":39.99,"currency_code":"USD","in_stock":false},{"title":"Warranty 2 Year","offer_id":43391773769818,"sku":"BWCS-MTV430SL-2","price":46.99,"currency_code":"USD","in_stock":false},{"title":"Warranty 3 Year","offer_id":43391773802586,"sku":"BWCS-MTV430SL-3","price":51.99,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-MTV430SL-1.webp?v=1779141870","url":"https:\/\/batteryweb.com\/products\/motorola-moto-edge-50-neo-5g-replacement-battery-391v-4150mah-li-polymer","provider":"BatteryWeb","version":"1.0","type":"link"}
