The differences are as follows:

1. Different appearance

The 48-volt 12-amp battery is shorter and wider

The 48-volt 20-amp battery Relatively tall and narrow

2. Different currents

The current output of a 48V 12A battery is smaller than that of a 48V 20A battery

3. Driving mileage varies

A 48-volt 20-amp battery can run about 130 miles on a scooter

A 48-volt 12-amp battery can only run about 70 miles on a scooter

4. Different weights

A 48V 12A battery weighs about 8.3kg

A 48V 20A battery weighs about 13.4kg

Extended information:

Take lead-acid batteries as an example:

There are new and breakthrough developments in the deep cycle life performance of this type of battery. The main manifestations are:

1. The initial discharge capacity at 2h rate (5A) reaches 14Ah; the specific energy at 2h rate reaches 38Wh/kg;

2. The cycle life of 100% discharge depth exceeds 400 times, the total released capacity is 4500Ah, and the corresponding accumulated mileage is about 18000km (based on 4km/Ah, the same below).

3. The highest deep cycle life is more than 600 times, the total released capacity is 6151Ah, and the corresponding cumulative mileage is about 24,600km. If the capacity is less than 7Ah as the end of life mark, the deep cycle life is 943 cycles, the total released capacity is 8710Ah, and the corresponding cumulative mileage is about 34800km. If the deep cycle life is 250 times or the battery pack has a total released capacity of 2250Ah and a corresponding cumulative mileage of 9000km, it can be guaranteed to be used for one year.
