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
capacity by the number of cells with total voltage stay the same. The voltages 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 discharg-
ing 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 volt-
age, 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.
