Charging.
During the 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 from the battery
manufacturer. Only batteries that are expressly stated to be capable of quick-charge should to be charged
at rates higher than the standard charge current.
Connecting the battery to the output socket of the charger: Red is positive and black is negative.
Due to the difference between resistance of different cables and connectors, the charger may be unable to
detect the correct 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 manual from the battery manufacturer pertaining to charging methods, recommended
charging current and charging time. Lithium batteries should be charged according the charging instruction
provided by the manufacturer only.
Attention should be paid to the connection of Lithium battery in particular.
Do not attempt to disassemble a battery pack arbitrarily.
Please note that Lithium battery packs can be wired in parallel and in series. In parallel connection, the
battery’s capacity is calculated by doubling a single cell’s capacity. They stay the same as a series wired
pack. It is recommended to only charge series wired packs.
