Charging
During charge process, a specic quantity of electrical energy is fed into the battery. e charge
quantity is calculated by multiplying charge current by charge time. e 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
quickcharge 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 dierence 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 nor-
mally goldplated should be tted to both ends.
Always refer to the manual by battery manufacturer about charging methods, recommended
charging current and charging time. Especially, the lithium battery should be charged according
the charging instruction provided by the manufacturer Strictly.
Attention should be paid to the connection of lithium battery especially. Do not attempt to
disassemble the battery pack arbitrarily. 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 single battery capac-
ity by the number of cells with total voltage stay the same. e voltages imbalance may cause re
or explosion .Lithium battery is recommended to charge in Series.
Discharging
e main purpose of discharging is to clean residual capacity of the battery, or to reduce the
battery voltage to a dened level. e same attention should be paid to the discharging process as
charging. e nal discharge voltage should be set up correctly to avoid deep-discharging.
Lithium battery can not be discharged to lower than the minimum voltage, or it will cause a
rapid loss of capacity or a total failure.
Generally, lithium battery doesn’t need to be discharged. Please pay attention to the minimum
voltage of lithium battery to protect them.
Lithium batteries are recommended to be discharged partially rather than fully. Frequent full
discharging should be avoided if possible.
