Xingheng 48V batteries are all series 13 ternary lithium or lithium manganate, all of which are single-string 3.7V The charging voltage of 13 series is/kloc-0 * 4.2v = 54.6V. There are generally three kinds of 48V lithium battery chargers in the market, and the lithium ion of 16 series is 58.8V

The terminal charging voltage (also called limit voltage) of the battery is 1.2 times the rated voltage. Therefore, regardless of the battery capacity (20Ah or 12Ah), the terminal charging voltage of a 48V battery is about (48V× 1.2 = 57.6V), which will damage the battery if it is too high or too low.

According to the battery industry standard, the standard charging current is110 of rated capacity, and the charging time is 15 hours (constant current charging). Because the electric vehicle charger usually uses a large current to charge, it can shorten the charging time. Generally, the initial charging current of 20Ah electric vehicle charger is about 2.8A, and it will drop to about 2A near the end of charging. 12Ah charger, these two currents are about 2.2A to1.5a..
