⒈The typical voltage of lithium iron phosphate battery cell is 3.2V, lithium ion 3.7V
⒉Lithium iron phosphate is resistant to overcharge and overdischarge, and it can recover more than 80% after being overcharged to 0 for a short time. Irreversible damage will occur when lithium ions are overcharged to 2.6V.
⒊Lithium iron phosphate is resistant to overcharge to 100% without fire and explosion. LiFePO4 battery pack ，Lithium-ion batteries will deflate and swell when they exceed 4.35V.
⒋ Lithium iron phosphate puncture will not catch fire or explode. Lithium ion will.
⒌Lithium iron phosphate is resistant to high temperature and can be used after recovery of more than 200 degrees. Lithium-ion doesn't work.
6.Lithium iron phosphate can discharge with high current, above 10C20C, and lithium ion can only discharge at 3~5C.

How to choose a portable car starter battery supply? Let's briefly talk about how to choose a car emergency start power supply from an intuitive user experience.
1. The full power start and the non-full power start (that is, the capacity remaining at 20% or more), the feeling of starting the car is the same, that is, the feeling of strong power is the same;
2. The car can be started under a certain wide temperature range, such as -20℃～60℃, the car can be easily started;
3. The average power consumption of the number of times to start the car is almost the same, that is, the current consumed by each start is almost the same;
4. The power consumption of starting the car is relatively slow. For example, under the same capacity, the more times it can be started, the better it is generally;
