WARNING AND SAFETY NOTES
PROGRAM FLOW CHART
Attention should be paid to the connection of Lithium battery especially.
Do not attempt to disassemble a battery pack!
Please be aware 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 reached 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.
