How to choose a robot battery
For power batteries, choose a battery with a large discharge current and a high capacity-to-weight ratio.
Generally, if you need a lot of current, the first choice is the nickel-cadmium battery. Although it is heavy metal and polluting, its discharge current is incomparable with other batteries. So many devices such as handheld walkie-talkies are still used.
In contrast, Ni-MH batteries are slightly worse, but more environmentally friendly.
If the robot is larger, you can consider using a small enclosed lead-acid battery, because its discharge capacity is also relatively strong, but because it has a direction, it cannot be upside down, so you must choose a closed maintenance-free battery, and try not to let the battery Tilt or even upside down.
