WARNING AND SAFETY NOTES
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’s capacity by
the number of cells with total voltage stay the same. The voltage’s
imbalance may cause fire or explosion .Lithium battery is
recommended to charge in series.
Discharging
The main purpose of discharging is to clean residual capacity of
the battery, or to reduce the battery?voltage to a defined level.
The same attention should be paid to the discharging process as
charging. The final 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 the battery.
Some rechargeable batteries have a memory effect. If they are
partly used and recharged before the whole charge is
accomplished, they remember this and will only use that part of
their capacity next time. This is a ‘memory effect’ It is said that
NiCd and NiMH batteries are suffering from memory effect. NiCd
has more memory effect than NiMH.
Lithium batteries are recommended to be discharged partially
rather than fully discharged. Frequent full discharging should be
avoided if possible. Instead, charge the battery more often or use
a battery of larger capacity.Full capacity cannot be used until it
has been subjected to 10 or more charge cycles. The cyclic
process of charge and discharge will optimize the capacity of
battery pack.
