2.What kind of cells we use

Now many battery are using 18650 battery, while we use A level pouch cell.
There are many differences as below:
 



3.What the difference about NMC and LIFEPO4?

They are have below difference:

♣ Specific energy
When on same power,NMC batter's energy dnsity is more than Lifepo4.
For example,make a 3kwh battery pack,the NMC weight is about 25kg,the LFP weight is about 27.5kg

♣ Specific power
When on same power,NMC batter's works time is less than Lifepo4.

♣ Safety 
The Lifepo4 batteries thermal runaway temperature is 800ºC,The NMC batteries thermal runaway temperature is 200ºC
So lifepo4 battery is more safe.

♣ Life spa
Generally speaking,the lifepo4 cycle life is more than 3000 times,NMC is about 1500-2000times.
