Safety Precautions

  1. Please read this Manual carefully before using to make sure CB86-PLUS is safely operated.
  2. CB86-PLUS balance charger requires DC power supply, otherwise it cannot be used. You need to select a DC power supply with an output voltage of 10.5V-15V and an output current not less than 15A.
  3. The CB86-PLUS input power supply cannot have great fluctuations, because it may burn the charger or damage the battery and power supply in extreme cases of current fluctuations. For example, the input protection voltage of the charger should be set according to the specifications of the input power supply to avoid overloading of the power supply. Some power supplies have overload protection, which will produce large fluctuations in voltage.
  4. Connect the charger to the power supply first, and then set the charging mode and charging voltage/current after the charger is turned on, then connect the battery, press the start button to charge (Never plug in the battery first and then power on the charger. When the battery is fully charged, please remove the battery first, and then power off the charger).
  5. CB86-PLUS is an 8-port charger that supports 8 independent 1-6S battery cycle charging, but it does not support 12S batteries. (If you want to charge the 12S battery, you must split it into 2 independent 6S battery packs for charging. The 2 6S battery packs can not connect to any external electrical parts, otherwise the charger or battery packs will be burned out)
  6. Keep the charger always away from children and pets.
  7. Keep the charger supervised when charging or discharging. If you have to leave, please disconnect the battery to prevent any unexpected dangers or damage.
  8. Ensure the charger settings match the battery packs with correct charging voltage and charging current. Otherwise, the battery will be damaged and even cause a fire.
  9. Do not leave metal or wire objects into the charger.
  10. If the battery has any abnormalities such as leakage, bulging, peeling of the outer skin, color change or deformation, please do not charge or discharge it.
  11. Do not mix batteries of different types, capacities or manufacturers.
  12. Do not refit or disassemble the charger.
  13. Do not put the charger or any battery on a flammable surface or close to a combustible material while in use. Do not (dis)charge in an R/C model or inside a full-sized automobile.
  14. Never block the air intake holes and never use in a confined space or high temperature environment, which may cause internal temperature protection and result in abnormal (dis)charging.

Introduction of CB86-PLUS

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.

Five Combinations of battery charging/discharging connection

 

CB86-PLUS has eight charging/discharging ports, supporting max eight combinations of battery charging/discharging connection. There are six independent sources which allow max 6S lithium battery charged/discharged with each port. When charging/discharging the non 6S battery, you can put 6 pieces of 1S OR 1 piece of 4S+1 piece of 2S OR 2 pieces of 3S OR 3 pieces of 2S OR one 6S battery to charge/discharge as picture shown below.

 

  1. 1 piece of 6S

 

 

  1. 1 piece of 4S + 1 piece of 2S

 

 

  1. 3 pieces of 2S

 

 

  1.  2 pieces of 3S

 

 

 

  1. 6 pieces of 1S




When you need to charge/discharge 6 pieces of 1S lithium batteries at the same time, the below 6 in 1 balance port adaptor cable is needed.

 

 

 

 

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.

 

 

 

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.

 

 

 

 

 

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.

 

 

 

 

 

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.

DISCHARGE

 

The discharging current of CB86-PLUS charger is fixed at 1.2A. And the discharging voltage can be set. Start the DISCHARGE mode, the charger will discharge the battery to the voltage you set. Make sure to set an appropriate discharging voltage, because over-low discharging voltage will cause over-discharging, which will damage the battery and shorten its life span. If the discharging voltage exceeds the battery's voltage, it will not be able to discharge. Because of the heat generated during discharge, the charger's cooling fan will work automatically. When the charger discharges the battery to the level equal to the set discharging voltage, the discharging is completed.

 

If the battery will not be used for a long time, it is recommended to discharge the battery to 3.8V before storing. If the voltage of the battery is too high, long-term storage may damage the battery.

 

Setting method: The setting method of discharging voltage is the same as that of charging voltage, please refer to charging voltage setting method.

 

 

 

 

 

 

 

STORAGE

 

Besides (dis)charge mode, STORAGE working mode is also available. If batteries will not be used for a long time, this mode can be used to (dis)charge them to the best storage status. That is, 3.8V for standard 1S battery.

When this mode is enabled, CB86-PLUS will automatically charge or discharge all batteries connected to 3.8V per cell one by one. If the voltage of any battery cell is higher than 3.8V, the charger will automatically discharge it to 3.8V. If the voltage of any battery cell is lower than 3.8V, the charger will automatically charge it to 3.8V. The charging current can be set, but the discharging current is 1.2A by default.

 

Setting method: The setting method of storage voltage is the same as that of charging voltage, please refer to charging voltage setting method.

 

 

 

 

 

 

Repair charge


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. The charger screen will display blue "Repair Charge"at this time, which is also called trickle charge, as shown in the picture below. The current during repair process is 10% of the current battery voltage, and the minimum is 300mA. In the repair mode, no matter how much charging current you set, the charger will repair it according to the small current in the repair mode. It won't start to charge normally according to the charging current you set until the voltage of the over-discharged cell rises above 3.0V.

 

Note: Repair charge mode will be activated only when the voltage of any cell connected to the charger is lower than 3.0V. If the voltage of all cells is higher than 3.0V, this mode won't be activated.

Troubleshooting for Common Problems

 

Fault self-detection warning

 

    CHARGER FAILURE!  Please contact Radiolink E-mail: after_service@radiolink.com.cn 

 

 

The main reasons for this warning are usually: abnormal input power supply, abnormal battery status, abnormal charger hardware etc. Power off and restart the charger to exit this warning page, and then perform specific troubleshooting.
1. Power supply troubleshooting: Set the charging current to 0.8A, and then start charging. Normal charging of the battery indicates insufficient or unstable power supply. Reduce the charging current or replace the power supply to solve the problem.

 
2. Battery troubleshooting: Set the charging current to 0.8A, and then start charging. If the battery cannot be charged normally, replace the battery and recharge it. If it still does not work, it may be a hardware problem with the charger. Please contact RadioLink after-sales service.

 

 

Notice troubleshooting (Beep sound)

During the charging process, when the charging voltage of a single cell is close to 4.2V, the charger will beep to alarm. The specific reasons are as following:
  1. Cable damage troubleshooting: Stop charging first, and then check if the connecting cables of the battery and the power supply are damaged.

 
  1. Power supply troubleshooting: Stop charging first, and then set the charging current to 1A (set 1A charging current for a 1000mAh battery) If the battery still cannot be charged normally, there is a power supply problem. Replace the power supply or reduce the charging current.

 

3. Battery troubleshoot: Stop charging first, and then set the charging current to 1A (set 1A charging current for a 1000mAh battery) Normal charging of the battery indicates that the battery has built -in circuit board protection. Set the charging voltage to 4.18V to solve it.

 
4. If you have tried all the above methods but the battery still cannot be charged normally,  it may be a hardware problem with the charger.  Please contact RadioLink after-sales service.

 

The beeping during the discharging process is usually caused by damaged cable or abnormal hardware of the charger.
