6.4 DISCHARGING A LITHIUM BATTERY
Use this setting to discharge a Lithium pack. The charge
current and pack voltage are adjustable using the methods
shown previously in the charge and balance instructions. Never
exceed 1C for the discharge rate and never use a final voltage
lower than what is recommended by the battery manufacturer.
The balance plug of the battery must be plugged into the
charger for a proper discharge to take place. Press and hold the
START/ENTER button to confirm cell count, then hold the button
again a second time to start the discharge process.
When discharging, the screen provides useful information like
the discharge rate, number of cells being discharged, battery
voltage and the amount of mAh, or capacity that the charger
has removed from the pack being currently discharged. Press Batt type/Stop to stop the
discharging process at any time.
6.5 VOLTAGE BALANCING AND MONITORING DURING THE DISCHARGE
The processor monitors the voltage of individual cells during ‘storage-mode’ and
‘discharge’ of a Lithium battery pack. It tries to regulate the voltages to be equal. For this
feature, the balance plug of the battery pack must be connected to the balance board of
the charger. If the voltage of any one or more cells varies abnormally during the procedure,
It terminates the process with an error message. If this happens, the battery pack contains
a bad cell, or there is a bad connection at the balance plug. You can easily know which
one cell is bad by pressing increase button with the error message on screen to show you
the individual cell voltages. This method of viewing cell voltages can be used during any
lithium battery charge or discharge process provided the balance lead from the battery is
plugged into the charger.
In this example, the charger found that the voltage of one of the
cells in this 4S pack is too low.
By pressing the “increase” button when the error message is
displayed, we can see that cell #4 is reading 2.18, which is below
the minimum recommended 3.0 per cell. If all cells read 0.00, the
balance lead from the battery may have come disconnected.
Also check your balance board connection at the charger.
