LiFePO4 batteries that you'll find in some vehicles (more often than not for running accessory loads, not starting the engine - though some models are intended

LiFePO4 batteries that you'll find in some vehicles (more often than not for running accessory loads, not starting the engine - though some models are intended for dual purpose use) usually have a decent degree of intelligence baked into an on-board BMS system. Typical car batteries are not yet so 'smart'. The post-battery-swap 'coding' that many euro vehicles need is to instruct the car-side BMS about the battery's characteristics so that it can tune things like its start-stop routine, alternator behavior, etc. to optimize battery life and resilience.
