When the lithium iron phosphate battery pack is packaged, different capacities and voltages are generally realized in parallel or in series. In the lithium-ion battery pack, multiple lithium-ion batteries are connected in series to obtain the required working voltage. If higher capacity and greater current are required, lithium-ion batteries should be connected in parallel.

Lithium ion battery pack 48V20AH All lithium ion battery packs are composed of single lithium ion batteries in series or parallel; The way of adding new voltage is to connect lithium ion batteries in series and add the voltages;

The lithium ion battery pack 48V20AH is generally 3.5V single lithium ion battery, so the 48V lithium ion battery pack should be 48/3.5=13.7, taking 14 in series.

If the manufacturer has supplied a set of 12V lithium-ion batteries, four of them can be connected in series. As long as the output voltage is 48V, the current is 2A or 4A. If the 2A is fully charged for about ten hours, this is when there is still a certain amount of power in the battery. If you buy a 4A, the time will be reduced by half, and you can fill it up and down in five hours.
