Electric remote control cars mainly use two kinds of batteries: nickel-metal hydride batteries and lithium batteries. When you buy a rc car with an RTR kit, it will probably come with NiMH batteries because it costs less compared to Lithium batteries.remote control  hobby， However, most players play a lot and finally choose lithium batteries. After all, compared with nickel-metal hydride batteries, lithium batteries have higher energy density, smaller weight and volume, and more stable continuous discharge.

NiMH batteries are easier to use. They must be fully discharged before charging and fully charged before storage (unless the manufacturer states otherwise). NiMH battery chargers are also simple. Lithium batteries cannot be fully discharged and must be stored at 50-70% capacity. Charging must be done with a balanced charger.

What these two types of batteries have in common is that by connecting cells in series or in parallel inside the battery pack, batteries of different voltages and capacities can be made. Care should be taken not to drop the battery or damage the battery case as this could cause a short circuit. Both batteries must be disposed of properly as hazardous waste.
