RC cars on a Ni-Mh battery

 

— specialized batteries made using nickel-metal hydride technology, like other batteries, are superior to replaceable batteries in terms of capacity and compactness and are better suited for powerful electric motors. Ni-Mh batteries themselves are notable primarily for their ability to tolerate high charge and discharge currents without consequences - the first is important given the “voracity” of electric motors, the second has a positive effect on charging speed. In addition, such batteries are resistant to low temperatures, do not have a "memory effect", and are relatively inexpensive. At the same time, they are inferior to Li-Pol cells in terms of capacity (with the same dimensions).
