Part 4. Working Mode of CB86-PLUS
There are three working modes of CB86-PLUS: CHARGE/ DISCHARGE/ STORAGE. But when the
voltage of any cell connected to the charger is lower than 3.0V, CB86-PLUS will automatically
recognize that the battery has been over-discharged, and automatically trigger Repair charge mode.
4.1 CHARGE
When multiple sets of batteries are connected, the charger will charge all connected batteries in turn
according to the sequence of the charging port numbers if there is no designated charging port
sequence. You can set the same charging parameters for all ports, or set different charging
parameters for each port.
Note: During the charging process, if the input power supply voltage drops by more than 9%, the
charger will automatically limit the current to keep the power supply voltage falling within 5%-8%
during charging.
4.1.1 Recommended charging voltage
1. Ordinary lithium battery: The recommended charging voltage for lithium batteries is 4.2V, and the
maximum charging current cannot exceed 6.0A. Because CB86-PLUS charger is charged by the
balance port of the batteries and the safety current of the silicone wire of the balance port cannot
exceed 6.0A. If the current is too high, there is a risk of overload.
2. High voltage lithium battery: The recommended charging voltage is 4.35V.
3. Lithium-iron battery: The recommended charging voltage is 3.6V.
4.1.2 Recommended charging current
Under CHARGE mode, the values of voltage and current can be customized. The full voltage of a
standard lithium battery is 4.2V per cell. Please set the current according to the battery capacity.
Generally, in order to protect the battery, the charging current of the battery is set to 1C according to
the battery capacity.
For example, 1000mAh lithium battery can be charged with 1A current.
2000mAh lithium battery can be charged with 2A current.
If you want to complete the charging as
quickly as possible, you can also set a larger charging current.
