-===== Highlights & Features =====
-  * Real-time monitoring of string voltage, charge-discharge current, charge-discharge state and string SOC.
-  * Monitor the voltage, impedance, temperature, SOC and SOH of each battery with BM-CS cell sensors and the specially designed isolated power bus.
-  * Advanced one-step auto-sensing for individual address. No more manual intervention and setup needed, reducing workload and setup errors.
-  * Advanced measurement algorithm, no need to discharge large current and measurement can be lossless.
-  * Balancing function: Keep voltage balanced during the floating charge process of battery pack, keeping the individual battery in the best state, extending backup time and life span of battery pack.
-  * Communication is based on power-isolated RS485. Secure and stable.
-  * Quickly locate the alarmed or faulty battery pack in machine room.
-  * External split-core Hall Sensor, measuring charge-discharge current in different ranges.
-  * Isolated voltage in communication interface: AC 3750V
-  * Supports up to 120 batteries (BM-CS)
