This board can do any kind of 4 to 10 strings. Please take a message when you take a picture. We have good configuration parameters to achieve the number of strings you want.
Configurable parameters: overcharge point 2.8V-4.375V range configurable, one step per 25mV;
Over-distribution 1.4V-2.900V range is configurable, one step per 100mV;
When photographed, the above configuration parameters are defaulted. Of course, you can also leave a message for your own parameters. We will configure it for you, but it must be a parameter within the configurable range.
