1. Floating Battery Balancer: smart cell balancer starts at/ over 3.80V, but it acts only on cells with volt variances, higher by 40mV than the lowest one. The bleeding current dissipates by from 40mA to 300mA,

2. Mosfet Management: Sense circuit designed for a purpose to keeping Mosfets from all being burnt down..

3. Auto Shut Down Mode with no current consumption: System shuts, showing 0 volt measured at terminals in 2 conditions as follows: (1).When a status of no load lasts for 120 hours and, (2).when it is in UVP status.

4. Low Voltage Start Energy Reserve (LVSER): LVSER mode acts at cell volt dropping down to 2.90V, to break off  lower current drains and slow down capacity loss, which is not involved with driving or igniting.The LVSER Mode is energy-saving mode to maintain margin capacity to start up the car again at its low voltage, LVSER Volt will keep dropping from 2.90V until 2.4V with load, or stay at 2.9V,while via an external switch.

5. LVSER Disabled: LVSER function will self-disable once when car alternator fails to supply power to battery.During this moment, the LVSER Disabled can assure the battery to enjoy reserve capacity or originally stored energy (RC value, Reserve Capacity Value).

6. BEMF protection: The BMS has protection for itself conducting back electromotive forces from the car.
