What should I pay attention to for lead-acid batteries for electric vehicles? Can I change the lithium-ion battery?

1. When refitting, consider the issue of volume and space. Under the same capacity, the volume of the lithium-ion battery is only half of that of the lead-acid battery, so it can definitely be installed, but pay attention to some shape and packaging issues. After all, the space on the car is not necessarily If it is in the same direction as the battery, you should consider fixing it reliably to avoid vibration and fall. Moreover, when economic conditions permit, it is of course hoped that the larger the capacity of the modified lithium-ion battery, the better. Therefore, it is necessary to make full use of the upper space and choose a battery with a reasonable shape for layout. If it is replaced with the same capacity, because the remaining space is large, it is necessary to find something to fill the excess space when replacing it to avoid shaking and falling off the lithium-ion battery when driving. 2. When disassembling the battery, although the battery output is positive and negative, it is very simple, but it should be removed one by one. Wrap the outer wire ears with tape, and then note the ± mark, so that when you install it back, you should remove it one by one. Connect the positive and negative pairs one by one to avoid connecting the positive and negative when you are confused, or accidentally short-circuit the positive and negative batteries of the positive and negative batteries, causing safety problems. 3. When purchasing lithium-ion batteries, it is best to ask the merchant to equip the same or similar plug terminal. If the shape of the plug is different, some may need to be crimped or welded, or even to change the line, etc., be sure to pay attention to the current level. Optional specifications, it is best to put a multimeter DC, re-measure the voltage when wiring, to avoid the positive and negative reverse. Remember, the positive and negative electrodes must be placed separately, and do not perform operations such as grounding the negative electrode.
