Can the sweeping robot be replaced with a lithium battery?

If the battery of your previous sweeping robot is not a lithium battery (such as a nickel-metal hydride or nickel-cadmium battery, etc.), it is generally not possible to replace it with a lithium battery. The main reasons are as follows: 1) The voltage may not match. The voltage working range is different, and the voltage working range must be basically the same to work normally. For example, your sweeping robot previously used a nickel-metal hydride battery with a nominal voltage of 12V and a capacity of 2Ah. Its working voltage range should be between 9-14V. Then the working voltage range and capacity of the lithium battery used to replace this battery should be It is basically the same. For example, a 3-junction series lithium battery with a capacity of 2Ah or more can be used (with space to fit), and the operating voltage range is roughly 9-12.6V. 2) The charging mode is different. Ni-MH or Ni-Cd batteries use constant current charging, while lithium batteries must be controlled by constant voltage in addition to constant current. Otherwise, it may cause dissatisfaction or overcharge of the battery and cause safety problems. So if you want to use lithium batteries to replace the previous Ni-MH or Ni-Cd batteries, the charging circuit must be changed, or an external charging method must be used.
