What should I pay attention to when electric vehicle lead-acid batteries modified to a lithium ion battery?

1, when modified, to consider volume spatial problems, under the same capacity, the volume of the lithium-ion battery is half of the lead-acid battery, so it will definitely be loaded, but to pay attention to some shapes and packaging problems, after all, the space on the car is not necessarily Just one direction and battery, you have to consider fixing and reliably, and the alert vibrates fall. Moreover, in the case of the economic conditions, it is of course, the larger the capacity of the lithium ion battery, so it is necessary to use the upper space to select a reasonable profile battery. If the same capacity is replaced, because the remaining space is mostly, it is time to find something to fill the extra space, and the lithium-ion battery is swayed when the alert is driven.

2±Sign, when this is installed, it is correct, and the negative strip is connected back. When the guard is worked, it will be reversed, or the positive and negative battery is negatively touched to cause safety problems. 3.

When purchasing a lithium-ion battery, it is best to make the merchant with a consistent or similar plug terminal. If the plug is different, some may have to replenish the thread or welding, and even the transition line, must pay attention to the current size. Optional specifications, it is best to put a multimeter DC, and then re-measure the voltage, and the guard is reversed.

Remember, the positive and negative pole must be placed separately, do not perform the operation of the negative iron. 4, if there is a motor and controller, it is necessary to consider whether the main circuit route should be bold, you can check the electrician manual, see how many square wires can pass how much amps, if the original The car's line is fine, which will also leave safety hazards, and the efficiency and power effect will be discounted. 5, the lead-acid battery changes the lithium-ion battery, and the charger must be dedicated to the lithium-ion battery.

The lead-acid battery is blocked, and the output voltage of the general charger is high, and there are many pulse charging functions, so lithium ion battery It may be charged during charging, because there is a protective board protection, it will cause the charger output voltage to be not normal, and the backward monomer may be unconventional and cause damage. If the protector is broken, so high pressure charging, it is easy to cause explosions.
