TIME FOR A 12V (LV) BATTERY REPLACEMENT ON MY F150 LIGHTNING - DIY INSTALLATION AND BMS RESET

EV Channels Review

This video provides a practical, DIY guide to replacing the 12-volt (LV) battery in a 2022 Ford F-150 Lightning. The host, Brandon Flash, clearly explains the necessity of this procedure, even in EVs, due to the constant draw on low-voltage electronics. He details the symptoms that indicate a failing battery, such as strange electrical behavior, and notes that his 3-year-old truck was showing signs of its original battery nearing the end of its life. The replacement process itself is presented as straightforward, requiring basic tools like an 8mm, 10mm, and 12mm socket. Key steps include locating the battery behind a panel, removing a bracket, and disconnecting/reconnecting the terminals. A crucial post-replacement step is the BMS reset procedure, which involves putting the truck in accessory mode, flashing the headlights five times, and pressing the brake pedal three times, confirmed by a flashing battery icon. The host also touches on potential recalibration needs for the front trunk and windows. While no specific trim level is mentioned, the focus is on the technical procedure applicable to the F-150 Lightning model year.
