Pay attention to these when replacing lead-acid batteries with electric vehicles
When replacing lead-acid batteries with lithium batteries, pay attention to the following points
First, the battery space problem
It is feasible to replace lead-acid batteries and lithium batteries with the same capacity and voltage, but it is necessary to consider whether the size of the battery can be installed in the original position, whether it protrudes or is squeezed, because the squeezing and moisture will damage the internal battery. Short circuit phenomenon.
So , the top important is keep the same size
Second, you must use a charger that matches the type of battery
Lead-acid batteries and lithium batteries have the same capacity and voltage, and chargers are also used indiscriminately, because the charging voltage and current of each stage required by the two batteries are not equal. When the lead-acid battery is charged, the charger voltage is high. The lithium battery has high technical requirements, so when charging, the charger uses constant current and constant pressure charging, and the lead-acid lithium battery will cause overshoot and danger of explosion.
so , Do not use the orignal charger
Three, socket replacement
Because the interface between the lead-acid battery and the lithium battery is different, the battery must be replaced with a matching socket. Do not plug it in and use it. It is easy to cause the lithium battery to short-circuit, which is dangerous.
So, pls charge the battery with correctly matching socket
4. After replacing the battery, the original charging port cannot be used for charging
Because of the different charging principles, if the original charging port on the electric vehicle is used for charging, the circuit will be damaged and the lithium battery will be short-circuited.
So the original charging port cannot be used for charging
5. After replacing the battery, the controller does not need to be replaced
It is also important to mention here that replacing the battery can only replace the same capacity and the same voltage, and cannot replace the one that does not match the previous battery capacity and voltage. This will burn the controller and damage the electronic components such as the motor hall. As long as it matches the capacity and voltage of the original battery, there is no need to replace the controller.
