    Lead-acid batteries and can be used for the first cycle of charge, with even the low-energy - the weight and energy - volume ratio, can supply a high momentary high current means high power - weight ratio is very low because of the cost for electric bicycle use, In view of this combination of characteristics of these two batteries.

    The lead-acid battery to use most early, and may circulate the charge, has the really low energy - weight and energy - volume ratio, can supply the high instantaneous big electric current, signifies has the high power - weight ratio, because the cost is really low is suitable for the electrically operated bicycle use, has 鑑 unifies this two kind of battery characteristic in this.
