Imaxrc B6-TWINS - Manual (Page 11)

The processor monitors voltage of each cell when the battery packs are during its 'storage' and
'discharging' process. The achieve this feature, plug each battery to the charger individually. If
voltage of any cell is abnormal, B6 Twins will show error massage and terminate the program
forcibly. So if there is battery damage or disconnection, you can see the error message and
press INC to know which cell is damaged.
WARNING AND SAFETY NOTES
Please bear in mind the following points before commencing charging:
charging:
Did you select the appropriate program suitable for the type of battery you
are charging?
Did you set up adequate current for charging or discharging?
Have you checked the battery voltage? Lithium battery packs can be wired in
parallel and in series, i.e. a 2 cells pack can be 3.7V (in parallel) or 7.4V (in
series).
Have you checked that all connections are firm and secure? Make sure there
are no intermittent contacts at any points in the circuit.
During charge process, a specific quantity of electrical energy is fed into the battery. The
charge quantity is calculated by multiplying charge current by charge time. The
maximum permissible charge current varies depending on the battery type or its
performance, and can be found in the information by the battery manufacturer. Only
batteries that are expressly stated to be capable of quick-charge are allowed to be
charged at rates higher than the standard charge current.
Connect the battery to the terminal of the charger: red is positive and black is negative.
Due to The difference between resistance of cable and connector, the charger cannot
detect Resistance of the battery pack, the essential requirement for the charger to work
properly is that the charge lead should be of adequate conductor cross-section, and high
quality connectors which are normally gold-plated should be fitted to both ends.
VOLTAGE BALANCING AND MONITORING IN THE DISCHARGE PROCESS
VOLTAGE BALANCING AND MONITORING IN THE DISCHARGE PROCESS
The processor detects voltage of one cell is too low.
DISCHARGE OF NiCd/NiMH BATTERY
The 4th cell was damaged. The value of voltage may be zero if
disconnection occurs.
This program is for charging and discharging of NiCd/NiMH batteries
associated with R/C models applications. You can press START/ENTER
key to make it blink and then INC or DEC to change the parameter
value. Press START/ENTER key to store the value.
This program charge the battery using the current you set up. In the
'auto' state, you should set up the upper limit of the charge current to
avoid damage by excessive feeding current. Some batteries of low
resistance and capacity can lead to higher current in the 'auto' charging
mode. But in the manual mode, it will charge with the current you set.
You can make it blink in the current field and press INC and DEC at the
same time to switch mode.
