Heltecbms 4s 5s lto bms 6s 12v 24v 7s 8s 9s 10s 2.3v 2.4V Lithium Titanate Battery Protection Board balanced BMS

Note:

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.
