Q: Why my CB86PLUS can’t be charged and there's notice of the input power is low displayed on the screen?
A: Double check the power source if the input power is too low. The standard input power of CB86PLUS is 10.5-15V. The notice will pop out if the input power is lower than 10.5V.
Q: What if the screen display becomes faint or flashing?
A: Firmware needs to be upgraded and then calibrate the voltage.

Q: Why my C8B6PLUS stops automatically while it's working?
A: 1) Check if the charging time is set at the right top of the screen. The charging time is unset when it displays as TIME 00:00. If it is 00:10, it means the charging time is set as 10 minutes.
2) If the temperature is too high, the charger will stop to protect.
Q:Why my CB86PLUS can’t function when there's notice of Repair charge displayed on the screen?
A: If your battery is over discharge and the voltage of whichever cell is less than or equal to 3.0V, CB86PLUS will automatically activate the battery repair function. That is, repair charging with the repair current as 20% of current battery voltage. For example, if the current battery voltage is 2.1V and the repair current will be 0.4A. All other cells with more than 3.0V will stay in Repair Charge mode until the first one is charged to 3.0V. After that, CB86PLUS will automatically change to the normal current as 6A.
Q: Why key buttons of my CB86PLUS still work but the screen gets blank/black?
A: It's because of the bad wire connection to the screen. Please remove the cover of CB86PLUS and reconnect the wire.
Q: Why is there no data of each cell showing on the screen after batteries are connected to my CB86PLUS? E.g. I connect a 3S LiPo battery but there are voltage data of only 2 cells?
A: Try to connect another battery to the same port to check if the display is normal. If it is, then the cell that doesn't display is broken. Or you can check the battery with a multimeter to see if there's voltage for all cells. If all works, then it must be the PCBA board broken and needs to be repaired.
Q: Why my CB86PLUS doesn't automatically switch to next charging port when the current one has completed charging?
A: 1) Try with a new battery to the first port to see if it switches automatically. If it doesn't, test if the second port functions. If the second port works, then it must be the first one malfunctions and needs to be repaired.
2) It's also probably because of the internal resistance of the aged battery and takes time to recharge. So, it won't automatically switch to the next charging port at once. You can test by changing a new battery to charge with the first port and see if it can automatically switch to the second port when it's fully charged.
Q: Can the discharging current and voltage be personalized?
A: The discharging current of CB86PLUS is fixed as 1.05A but the discharging voltage can be personalized.
