在充电前必须先了解清楚所用电池允许的最大充电电流，使用过大的电流对电池充电会对电池的寿命造成
影响甚至损坏，过大的电流也会造成充电过程中电池发热甚至爆炸。电池充放电能力一般以C数来标识，
充电C数乘以电池容量就是电池所支持的最大充电电流，例如1000mAh的电池，标识充电能力是5C，那么
最大充电电流为：1000×5=5000mA=5A，也就是最大支持5A充电。对于锂电池而言，如果无法确定电池
充电C数，为了安全起见请将充电电流设定在不大于1C的值。
充电C数与充电时间的参考关系：充电时间≧60分钟/充电C数（例如使用1C充电，充电完成时间大约需要
60~70分钟），由于电池转换能效的差异，此时间有可能会有所延长。

Make sure to know the maximum charging current of the battery before charging, never use excessive current
to charge to damage your battery, which will result in over heat even explosion during the charging process.
The charging and discharging capacity of battery is usually marked with C value. Multiplying the charging C
value and battery capacity equals to the maximum charging current supported by the battery. For example,
for a 1000 mAh battery with a charging capacity of 5C, the maximum charging current would be 1000*5=
5000mA; therefore, the maximum charging current is 5A. For a lithium battery, if it is impossible to confirm
the supported charging C value, please set the charging current below 1C, for the sake of its (lithium battery)
safety. The reference relation between C value and charging time: charging time ≥60 minutes/ charging C
value (e.g. it needs around 60-70 minutes to complete charging with 1C).
Due to differences in battery conversion efficiency, the time to complete the charging might be extended.
