Single Cell voltage working range | 3.0v-4.5v |
| Balanced Cascading | Support (Don't advice) |
Voltage balancing accuracy | Adjacent voltage difference 30mV (typical value) |
Undervoltage protects sleep voltage | Enter sleep state when the adjacent voltage difference is less than
30mV |
Equilibrium method | Detect that the voltage difference between adjacent batteries is
greater than 100mV and trigger equalization;
Stop working when adjacent voltage difference is less than 30mV |
Equilibrium current | 0.05V voltage difference balancing current 0.5A
0.1V voltage difference reaches the maximum balancing current of 1A |
External power supply | No external power supply required;
Relying on internal energy transfer of the battery to achieve
adjacent equilibrium |
| Quiescent operating current | 10uA |

Packing List
Wire connect
Wiring definition
B-,the total negative pole of the battery pack(the negative pole of
the first battery).
B1, the positive electrode of the first battery.
B2, the positive electrode of the second battery.
B3..... and so on.
Direction for use
①The first, terminal wire is soldered to the battery
pack.Next,Connect the terminal wire to the PCBA.
(2)13 or more string plugs need to be inserted obliquely,first
touch the B-pins and insert them obliquely upwards,otherwise it may
cause the board to burn out.
