Can we use a lithium iron Phosphate battery as a regular starting batter in car
Can we use a lithium iron Phosphate battery as a regular starting batter in car Technically, a 12V (4S) assembly of 314Ah LiFePO4 prismatic cells can start a car engine, but it is generally not recommended to use them as a "regular" daily starting battery without specific modifications, high-quality BMS, and proper environmental precautions . While 314Ah offers massive capacity, the cell type is designed for deep-cycle energy storage (like solar setups) rather than the high-amp burst needed for cranking, and they face severe limitations in vehicle environments. Why You Should NOT Use Them (Risks & Challenges) · BMS Shut-off Danger: If the Battery Management System (BMS) detects a high-current surge (cranking) or high voltage from the alternator (over-voltage), it may shut off completely while driving, causing sudden power loss. · ...
