3w or so, 10 channels.
This kind of battery performance measurement is commonly used, such as current, voltage, capacity and cycle performance.
What's better for us is Zana in Germany? Im6e
This price is slightly higher than 0.2 million/200 thousand, which is related to the euro exchange rate This belongs to the electrochemical workstation, and it is a bit wasteful to measure the charge and discharge by light.
The charging and discharging speed depends on the number of electrode materials, and has nothing to do with current and instruments. If the current is too large, the battery performance may decrease. The maximum current of all charging and discharging instruments is different. The specific charging speed depends on how many active substances you have. Also, I don't recommend testing only one battery at a time, because there are too many factors that affect the performance of the battery. Each method is best to measure several more batteries and take the average. If we want to look at long-term stability, single-channel batteries certainly have no advantage. So I feel that Blue Power is still good, cheap, with many channels and simple operation.
