Can the electric sweeper use lead-acid batteries instead of lithium batteries?

1. Theoretically speaking: as long as the voltage and capacity are sufficient. 2. In fact, the volume and weight of lead-acid batteries are generally more than 50% larger than that of lithium batteries. Therefore, if you want to change from lithium batteries to lead-acid batteries, the first consideration is the space problem of the installation battery, because the battery space of the electric sweeper is all Relatively small, lead-acid batteries may not fit in. 3. If the space is sufficient, the controller and charger should be replaced by lead-acid batteries instead of lithium batteries. The undervoltage of the 48V lithium battery controller is 39V, and the undervoltage of the 48V lead-acid battery controller is 42V. If the controller is not replaced, the lead-acid battery will be discharged to 39V before powering off. At this time, the lead-acid battery has been over-discharged and the lead is easily damaged. Acid battery, so you need to change the 48V lead-acid battery controller. If you don’t change the controller and there are 2 bars of electricity, stop driving, charge it, and beware of over-discharge. The charging current and voltage of lead-acid batteries and lithium batteries are different, so it is necessary to change the 48V lead-acid battery charger. There are two types of 48V lead-acid battery chargers: 20A and 12A, which must correspond to the capacity of lead-acid batteries. If a 20A charger is used to charge a 12A battery, the battery life will be shortened due to excessive charging current. In addition, pay attention to the capacity of the battery, the capacity of the lead-acid battery should not be less than the capacity of the lithium battery, otherwise the working time is less than the original.
