Can Lead-Acid Electric Vehicles Be Replaced with Lithium Batteries?
2 Answers
Electric vehicles with lead-acid batteries can be replaced with lithium batteries. Here are the details: 1. If replacing lead-acid batteries with lithium batteries, it is necessary to ensure that the voltage remains the same as the original lead-acid batteries. Additionally, the charger must be replaced with a dedicated lithium battery charger. However, there is another issue: improper installation or quality problems with the lithium battery may damage the controller. 2. When replacing lead-acid batteries with lithium batteries, the size of the battery compartment must also be considered. Generally, lead-acid battery compartments are relatively large, while lithium batteries are smaller. This factor must be carefully considered during replacement. If the gap after installation is too large, it can easily cause the smaller batteries to shake, reducing their lifespan. 3. Compared to lead-acid batteries, lithium batteries are less stable. If exposed to water or mishandled, there is a high risk of explosion. Another point to note is that lithium batteries have a multi-cell structure, meaning if one cell has an issue, it can affect the overall quality.
After I replaced the lead-acid battery in my electric vehicle with a lithium battery, I really noticed it became much lighter, with improved acceleration and range. But it's crucial to ensure the battery voltage matches the original system. If the voltage difference is too large, the charger needs to be replaced as well. Take my old electric bicycle for example—after a professional shop did the conversion, it's been running smoothly for several months, though the cost was higher, over a thousand yuan for the lithium battery. I recommend checking your vehicle's manual first or consulting a repair technician. Safety comes first, so don't attempt it yourself.
