You have to pay attention to verify the capacity and the voltage of the Lithium battery
pack. It may be composed of parallel and series connection mixed. In parallel link
the capacity of the battery pack is multiplied by the number of cells but the voltage
remains same. That kind of voltage imbalance causes a fire or explosion during
charge process. We recommend you compose the Lithium battery pack in series only.
Discharge
• The typical purpose of discharge is to determine the residual capacity of the battery,
or to lower the voltage of battery to a defined level. When you discharge the battery
you also have to pay attention on the process same as charging. To avoid the battery
becoming deep-discharged, set the final discharge voltage correctly. Lithium batteries
should not be deep-discharged to lower than the minimum voltage, as this leads to
a rapid loss of capacity or a total failure. Generally, you do not need to discharge
Lithium battery voluntarily.
• Some rechargeable batteries are said to have a memory effect. If they are partly
used and recharged before the whole charge is drawn out, they‘remember’ this and
next time will only use that part of their capacity. This is a ‘memory effect’. NiCd and
NiMH batteries are said to suffer from memory effect. They prefer complete cycles;
fully charge then use until empty, do not recharge before storage-allow them to self-
discharge during storage. NiMH batteries have less memory effect than NiCd.
• The Lithium battery prefers a partial rather than a full discharge. Frequent full
discharges should be avoided if possible. Instead, charge the battery more often or
use a larger battery.
• The brand-new NiCd battery pack is partially useful with its capacity until it has
beeen subjected to 10 or more charge cycles in any case. The cyclic process of
charge and discharge will lead to optimise the capacity of battery pack.
Those warnings and safety notes are particularly important. Please
follow the instructions for a maximum safety; otherwise the charger
and the battery can be damaged violently. And also it can cause a fire to
injure a human body or to lose the property.
