Product Information

  • On test at 0.5C at 24C these industrial marked 6Ah cells measure 5.6Ah

  • The use of a smart BMS with programmable  DOD (Depth of Discharge) and OCV (Open Circuit Voltage) values for calculation of capacity.

  • To extend life due to voltaic stresses on the cell, the DOD can be reduced which will increase cycle life from 800 cycles to over 2500.

 

Set BMS values depending on your chosen DOD values as shown in the data table below.

% Charge | DOD 100% OCV | DOD 85% OCV

       0                    2.50                           3.12

      10                   3.20                           3.23

      20                   3.26                           3.28

      30                   3.28                           3.29

      40                   3.30                           3.30

      50                   3.30                           3.30   

      60                   3.32                           3.31

      70                   3.33                           3.31

      80                   3.35                           3.32

      90                   3.36                           3.33

     100                  3.65                           3.50

  • For maximum capacity DOD=100% (5.6Ah) you can expect 800 cycles, after which the cell's capacity will be reduced by 20%

  • For improved life time DOD=85% (4.76Ah) you can expect >2500 cycles

  • The true capacity of a battery is only the same as the usable capacity if set at 100% DOD
