The 48V 200Ah 10kwh Powerwall LiFePO4 battery was invented in the second half of the 1990s, and like many other inventions, it took a few years for this battery to become practical. This compound is very stable, but the intrinsic internal resistance is usually too large. People use good conductors such as graphite-wrapped compounds to reduce the internal resistance.
This kind of battery has many advantages, the biggest advantage for radio amateurs is a relatively stable discharge voltage. When a traditional battery is fully charged, the discharge voltage is very high, and then the voltage gradually decreases as the discharge process progresses. The voltage of the 48V 200Ah 10kwh Powerwall LiFePO4 battery from China hardly changes with the discharge process. So what are the advantages?
1. Good high temperature performance
The 48V 200Ah 10kwh Powerwall LiFePO4 battery from China The electric heating peak can reach 65℃, while lithium manganate and lithium cobaltate are only around 55℃. Wide operating temperature range (-20C--65C), with high temperature resistance, the electric heating peak of lithium iron phosphate can reach 65℃, while lithium manganate and lithium cobaltate are only around 55℃.
2. Large capacity and light weight
The 48V 200Ah 10kwh Powerwall LiFePO4 battery from China often works under the condition that it is not fully charged, and the capacity will quickly drop below the rated capacity value. This phenomenon is called memory effect. Like nickel-metal hydride and nickel-cadmium batteries, there is memory, but lithium iron phosphate batteries do not have this phenomenon. No matter what state the battery is in, it can be used at any time without having to discharge it before charging. And the volume of lithium iron phosphate of the same specification and capacity is 2/3 of the volume of lead-acid battery, and the weight is 1/3 of that of lead-acid battery.
3. Lifespan improvement
The cycle life of lead-acid batteries is about 300 times, and the maximum is 500 times, while the 48V 200Ah 10kwh Powerwall LiFePO4 battery from China has a cycle life of more than 2,000 times, and standard charging (5-hour rate) can reach about 2,000 times.
The 48V 200Ah 10kwh Powerwall LiFePO4 battery from China should pay attention to waterproof and dustproof when using, so there should be no water in the storage place, which will affect the performance and service life of the battery.
