Maxcellent K150 High-Performance Portable Car Jump Starter 12V/24V emergency strong start battery power

Advantage 1: The thermal runaway temperature is much higher than that of ternary polymer batteries.The thermal runaway temperature of lithium iron phosphate batteries can reach over 200°C. Even if dropped into a fire, they are difficult to catch fire. Even in a car during summer with intense sun exposure, there is no safety hazard. However, ternary lithium polymer batteries have a safety temperature range of 60°C and once they experience thermal runaway, flames will spread widely and the combustion will be intense. Anyone with basic knowledge of batteries will not be able to leave them in the car for a long time.Advantage 2: Precisely matches the vehicle's electrical circuit with a 13V voltageThe working voltage of the vehicle's electrical system is approximately 11-14V. It perfectly matches the voltage of 4 sets of lithium iron phosphate batteries, truly allowing the vehicle to be charged without any noticeable impact. However, 4 sets of ternary polymer batteries are fully charged at a voltage of up to 16.8V, which is significantly higher than the standard voltage of the vehicle's electrical system. This can easily cause the vehicle's computer to report errors and even burn out various low-voltage modules directly connected to the battery!Advantage 3: Low self-discharge rate and support for full charge storageLithium iron phosphate batteries have stable chemical properties. When not in use, they have very little self-discharge, and they can be stored at full charge for a long time, allowing for years of standby. In contrast, high-rate lithium polymer batteries have high chemical reactivity and rapid self-discharge. Storing them at full charge can cause swelling, and due to safety concerns, they are not suitable for full charge storage in vehicles, resulting in a shorter standby time.Advantage 4: Slow performance degradation, long lifespanThe inherently more stable chemical properties result in slower performance degradation for lithium iron phosphate batteries. The cycle life of ordinary lithium iron phosphate batteries can reach around 4,000 times. Even for high-rate lithium iron phosphate batteries with more active chemistry, the cycle life is still above 2,000 times, far exceeding the 200-500 cycle life of high-rate lithium polymer batteries.
