Battery Management System
The BMS monitors the battery voltage with an accuracy of 0.3V. It performs this check before every scan, after a version command, and after a reboot command. If the battery voltage reaches the designated threshold, the system will shut down the battery, stopping sensor operation

Modify Settings
This option allows you to configure the BMS settings for maximum battery voltage and dischard threshold for your specific battery.
To ensure safe operation, you must enter the correct discharge threshold voltage and maximum battery voltage for your specific battery. These values are critical for system function.
Where to find these values: Check the battery manufacturer’s datasheet or product label for the recommended operating voltage range. If unsure, consult your battery supplier or refer to industry-standard values for your battery type (e.g., Li-ion, lead-acid, alkaline).
Entering incorrect values may cause the battery to over-discharge or overcharge, potentially leading to permanent damage, unsafe operation, or unexpected shutdowns.
ANB Sensors is not liable for any damage or issues caused by incorrect configuration. Please verify your battery specifications before entering the values.
