Compared to lead-acid batteries, lithium-ion batteries are the winner in terms of crushing performance. Last year, we had a lithium battery charging accident with a lead-acid charger here, and we lost our family of three. Lithium batteries are too delicate, afraid of cold, heat, water, bumps, and improper use of chargers. Moreover, the threshold for lithium battery technology is low, so low-quality lithium batteries have appeared in the market, causing great safety hazards. Recently, I changed to a new set of lithium batteries, and those who collect old batteries did not want them. The boss did not allow them to be stored in the store, so I had to take them home and bump into the empty space in the old yard, always treating them as "grandpas" and respecting them.

Speaking of lead-acid batteries, I have seen a group of lead-acid batteries fail after working for so many years. My analysis shows that the reason is that there is too much pressure inside the battery, and the cover plate of the battery is opened, causing the battery box to break and causing scratches on the customer's thigh. This is the most serious.

As for what people say about electric cars catching fire and exploding, I have also watched many videos online. Most of them are smoke coming from under the back seat of the electric car, which is usually the location of the controller and circuit. Also, an electric vehicle caught fire and exploded, causing the batteries to burst out. However, the batteries are not a big deal. Is it because of the batteries?

Also, when it comes to battery short circuits, it's usually a human problem. It's usually caused by the battery connection wire being worn out or the insulation skin melting due to the heat generated by the connection wire being too thin. Another issue is that the pressure strip of the fixed battery in the electric motorcycle model was not tightened tightly, causing the pressure strip to touch the column head and cause a short circuit. In fact, batteries are difficult to ignite. A few days ago, I received a short circuit from two sets of batteries, causing them to burn into black lumps and not catch fire. Therefore, as long as lead-acid batteries are installed properly, there is basically no problem.

Although lead-acid is not prone to problems, it is not always safe to do so. Anything that is related to electricity should be careful. While lead-acid is considered safe compared to lithium batteries, it has a rough skin and thick flesh.

Another issue is that the current design of bicycle electric vehicles has flaws, and if the safety of the battery connection wires and connectors is not taken into consideration, it is easy to squeeze the connection wires. We hope the manufacturer can improve this. So lead-acid batteries are safe enough, but we cannot take them lightly. Prevention is the eternal theme.
