Part 2. Introduction of CB86-PLUS
2.1 Functions
1. High Precision. With precision of 0.001V, which is 10 times precise than the competing products of
0.01V.
2. With 8 charging/discharging ports. Each port is compatible with 1S~6S battery and the parameters
of each port can be set individually.
3. With balance current of 6A, which is much higher than 0.5A of ordinary chargers and improves the
charging efficiency of the battery.
4. Integrated Protection. After setting the parameters of charging and discharging, the charger will
automatically scan the batteries of all ports and automatically start to take turns to charge or discharge.
5. Power supply self - adaptation. When the maximum output of the power supply cannot meet the
charging power, the charger will automatically reduce the current to adapt to the maximum output of
the power supply. The smooth power technology effectively solves the problem that some power
supplies cannot start the rated power instantly.
6. Intelligent battery repair function, which is also called Repair charge. When the charger is
connected to an over-discharged battery, the charger will automatically identify the over-discharged
cell, and then automatically trigger the Repair charge mode to protect the cell. When the voltage of
over-discharged cell rises to 3.0V, it will automatically charge according to the charging parameters
you set, which greatly prolongs the life span of the battery.
7. Polarity control. When there's reversed polarity connection, the charger won't work which ensures
protection to the charger.
8. Input over-voltage protection. If the input voltage of the power supply is too high, the charger will
automatically recognize it and make sure the charger won't be damaged.
9. Power management adopts switch circuit, with most efficient individual PUSH-PULL design for
each charging cell. There's no resistance consuming power when balance charging, which greatly
decreases the heat. Operating current is as low as 135mA with charging efficiency up to 97%. The
operating temperature remains 35°C no matter whether it is on standby mode or fully working mode.
10. Press one key to view all parameters of the battery at any time, such as: initial voltage, completed
voltage, capacity analysis of each battery cell and internal resistance display, so that the battery
charging voltage is more accurate.
11. Fast dynamic battery internal resistance display. Basic internal resistance display after ten
seconds of charging, which can quickly judge the balance and discharge performance of the battery
cell.
12. Support charging and discharging of different battery combinations such as 2pcs 3S batteries, 1pc
4S battery and 1pc 2S battery, 3pcs 2S batteries, 6pcs 1S batteries, which can be combined into 1pc
6S battery. It can also charge/discharge 6 cells of the assembled battery at the same time.
2.2 Upgrade instructions
New functions are added in the new firmware V2.5, and the usage is slightly different from the old
version firmware, so this manual is only applicable to CB86-PLUS chargers with firmware V2.5 and
above.
Note: If the charger is produced after November 1, 2021, users do not need to upgrade it. If the
firmware of your charger is the version below V2.5, after upgrading firmware V2.5 and above, there
