The BK+ terminal is connected internally to the Load+ terminal. The BK- goes to a
MOSFET transistor which will internally connect to the Load- terminal when the resistor is
enabled.
The figures below show the current flow under the various load and regeneration
conditions

By default, the Brake output is deactivated and may be controlled by user command or
script. The BMS supports Microbasic scripting that can be written using the PC Utility
accompanying the product.
If a Brake resistor is not needed, two other predefined implementations may be chosen:
a cooling fan or a heater function. These features utilize the temperature thresholds
configured in the utility. This guarantees that the pack is kept warm or cool enough
