Page 31: Soc Calibration
LiPo & LiFe, LiTo Battery Management System BMS16P V4.3 SOC Calibration The program calculates SOC according to the power charged or discharged from battery. Users need to setup battery power (WH) and battery capacity (AH) when turning on the BMS for the first time. After charging to Maximum voltage or discharge to minimum voltage, BMS will complete the SOC calibration and display accurate SOC.
Page 32 LiPo & LiFe, LiTo Battery Management System BMS16P V4.3 battery capacity will reduce over time. You may find that the SOC is not 100% when the battery is fully charged (each cell voltage reaches maximum value), such as 90%. This means battery WH or AH is only 90% of the original setting.
Page 33: Balancer
BMS16P V4.3 Balancer The BMS16P can restore balanced cell voltage status in the shortest time, it is based on a 1.2A balancing current per cell, with balancing accuracy of 8mV. Balancing can be operated in Storage, Charge, Discharge or in ALL modes, the feature can be configured in the program setup menu. The balance function is disabled by default.
Page 34: Balancing Indicator
LiPo & LiFe, LiTo Battery Management System BMS16P V4.3 Balancing Indicator From firmware v4.0, the BMS has a yellow indicator, when the BMS is balancing cell voltage in Storage, Charging or Discharging. The "yellow bar" will be displayed after cell voltage reading, when cell are not in balancing mode, the yellow bar will be not displayed.

LiPo & LiFe, LiTo Battery Management System LiPo & LiFe, LiTo Battery Management System BMS16 BMS16 BMS16P V4.3 Cell internal resistance (Impedance) test internal resistance (Impedance) test Internal resistance of an energy storage device, Internal resistance of an energy storage device, such as a battery, is an importance parameter that is an importance parameter that determines their power performance.
Page 36 LiPo & LiFe, LiTo Battery Management System BMS16P V4.3 EXAMPLE: One 16S LiPo battery pack is in discharging at 3A, BMS measured all cell internal resistance. The total battery resistance is 19.2mohm, and the difference of each cell resistance is 1.7mohm.
Page 37: Charge And Discharge Relay Lectotype For Bms16P
Charge and discharge relay lectotype for BMS16P The BMS16P can output 12V/3A to power the charge and discharge DCC/relay/SSR that is used for cut off charge or discharge when any cell voltage reach settings. The relay coil drive voltage must be 12V and the total current for charge and discharge relays cannot exceed 2.5A.
Page 38: Current Calibration (Shunt)
BMS16P V4.3 Current Calibration (Shunt) Current calibration is only required if you change the Shunt from the one supplied by Chargery which are calibrated at the factory. Use shunts which are 75mv or lower only. Press SET/START for 3 seconds to enter into Program Setup and find the Current Calibration, you can calibrate the current to improve the measurement accuracy.
Page 39 Current calibration is not suggested. We calibrate shunt and current before delivery. You only need to re- calibrate if you change shunts from the ones supplied by Chargery. If the current is not accurate, the WH and AH will not be accurate. SOC reading will also be wrong.
