Standard Battery Parameters
Be very careful to choose the correct voltage for different types of battery otherwise you may
cause damage to the batteries. Incorrect settings could cause the cells to fire or explode.
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. 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 manual by the battery manufacturer regarding the charging methods.
Operate according to their recommended charging current and charging time. Lithium batteries,
in particular, should be charged strictly according to the manufacturer’s instruction.
Close attention should be paid to the connection of lithium batteries.
Do not attempt to open, disassemble, or service the battery pack. Please get highlighted that
lithium battery packs can be wired in parallel and in series. In the parallel connection, the bat-
tery’s capacity is calculated by multiplying single the battery’s capacity by the number of cells,
bearing in mind that total voltage stays the same. If the voltage is imbalanced, it may cause a
fire or explosion. Lithium batteries are recommended to charge in series.
