WARNING AND SAFETY NOTES
Charging
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 can not 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.
Always refer to the battery manufacturer about charging methods,
recommended charging current and charging time. Lithium batteries
should always be charged according to the charging instruction
provided by the manufacturer.
Attention should be paid to the connection of lithium batteries.
Never attempt to disassemble a battery pack.
Please get highlighted that lithium battery packs can be wired in parallel
and in series.
In the parallel connection, the battery’s capacity is calculated by
multiplying the single battery capacity by the number of cells with total
voltage stay the same. Voltage imbalance may cause fire or explosion. Lithium
battery is recommended to charge in series.
