How Does the LiFePO4 Chemistry Enhance Battery Performance?
Lithium iron phosphate (LiFePO4) offers superior thermal stability, reducing fire risks. It operates efficiently between -20°C to 60°C and maintains 80% capacity after 4,000 cycles. Unlike lead-acid, it delivers consistent voltage under high loads, making it ideal for inverters and emergency systems requiring stable power output.
The crystal structure of LiFePO4 inherently resists thermal runaway through strong phosphorus-oxygen bonds, a critical safety advantage over other lithium chemistries. This cathode material maintains 95% round-trip efficiency even at 2C discharge rates, compared to 80-85% in NMC batteries. Its flat discharge curve (voltage variation <0.3V from 100% to 20% SOC) ensures sensitive electronics receive stable power. Field tests show only 2-3% capacity loss annually when stored at 50% charge - 5x better than lead-acid alternatives.

Why Choose USB-C and Car Lighter Outputs?
The USB-C PD3.0 port provides 100W bidirectional charging, compatible with modern devices like MacBooks. The car lighter port enables 12V/24V accessory use without converters. Both outputs are safeguarded by short-circuit and overcurrent protection, ensuring device safety during operation.
DEESPAEK Lithium Iron Phosphate (LiFePO4) Battery
These dual interfaces support 15 simultaneous device connections through integrated power distribution logic. The USB-C port negotiates voltage from 5V to 20V in 20mV increments, automatically matching connected devices’ requirements. For automotive applications, the 10A socket powers 120W air compressors for 90 minutes continuously without voltage sag. Users can simultaneously charge a 100W laptop and run a 12V/8A car fridge while maintaining 60% reserve capacity for emergency starts.
How Does It Compare to Traditional Lead-Acid Batteries?
Weighing 22kg (50% lighter than lead-acid), it offers 3x deeper discharge (100% DoD vs 50%) and 8x longer cycle life. No maintenance is required, and self-discharge is <3% monthly versus 5-15% for lead-acid. Despite higher upfront cost, its 10-year lifespan reduces long-term expenses.
