Comparison ENGWE M20 1000W Dual vs ENGWE M20 1000W

The capacity of the battery that the e-bike is equipped with (see "Application"), expressed in ampere-hours.

The battery capacity directly affects the operating time on a charge and, accordingly, the power reserve. However, in fact it hardly makes sense to evaluate these parameters by the number of ampere-hours. Firstly, the actual battery life will depend not only on the characteristics of the battery, but also on the power of the engine (which determines the power consumption of the machine). Secondly, the actual amount of energy stored in the battery depends not only on the capacity in ampere-hours, but also on the rated voltage; a more reliable unit in this sense is watt-hours, see Battery Capacity below for more details. So when choosing, it is better to focus not so much on the number of ampere-hours, but on the power reserve directly claimed by the manufacturer.
