Compared with lithium batteries and lead-acid batteries, lead-acid batteries are superior in crushability. Last year, we had an accident when charging lithium batteries with lead-acid chargers, and the family of three died. Lithium batteries are too squeamish. They are afraid of cold, heat, water, bumps, and indiscriminate use of chargers. In addition, the technical threshold of lithium batteries is low, so there are low-quality lithium batteries on the market. big safety hazard,

Besides lead-acid batteries, I have seen a group of lead-acid batteries have an accident over the years. I analyzed the reason for the excessive pressure inside the battery. The battery cover was broken open and the battery box collapsed, causing the customer's thigh to be scratched. This is the most serious.

As for the electric car that everyone said caught fire and exploded, I have also watched a lot of videos on the Internet, most of which are smoke from under the back seat of the electric car, which is usually the location of the controller and circuit. There is also an electric car that caught fire and exploded and blew out the battery, but the battery did not matter much. Could it be blamed on the battery?

There are also people who say that the short circuit of the battery is a human problem. Generally, the battery connection wire is frayed or the connection wire is too thin to generate heat and melt the insulation. There is also the electric motorcycle model of the fixed battery pressure strip not tightened the screw, so that the pressure strip touched the stud and caused a short circuit. In fact, the battery is difficult to burn. A few days ago, I received two sets of batteries that had a short circuit, and the batteries were burned into black lumps and did not catch fire. Therefore, as long as the lead-acid battery is installed, there is basically no problem.

Although lead-acid is not prone to problems, it is not without problems. Be careful with anything that is related to electricity. It is said that lead-acid safety is arrogant compared to lithium batteries, while lead-acid is rough and thick.

There is also a defect in the design of the current bicycle electric vehicle. If you don't pay attention to the safety of the battery cable and the connector, it is easy to squeeze the cable. I hope the manufacturer can improve it. Therefore, lead-acid batteries are safe enough, but we can't take it lightly. Prevention is the main theme that will never change.
