Electric car battery conversion: save hundreds of dollars and could lose your life!

Long-term Battery Reminder: Safety is the greatest savings. In the past few years, we have been concerned about a number of electric vehicle safety accidents caused by the private modification of batteries. Behind every accident is the neglect of safety boundaries. And the battery is the most central part of the electric car and the part that needs to be taken seriously. Fire warnings in many places: the risks of changing batteries should not be ignored! We combed through the e-bike fire cases made public by fire departments in more than two years and found that many of these accidents involved: - the use of inferior batteries. - Privately replace high-capacity, high-voltage batteries. - Situations where the battery does not match the vehicle, charger, etc. For example: - In April 2026, Hainan Fire Brigade reported a case of electric bicycle fire involving inferior batteries; - In 2025, fire departments in Ningbo, Zhoushan and other places will also publicly report fire accidents caused by modified batteries; In 2024, fire incidents caused by modified batteries were also reported in fire department cases in Shanghai, Hubei, and other regions. Behind many fire cases, all point to the same hazard: battery modification. Why is it so risky to modify batteries?
Many users modify batteries in order to "run farther" and "drive more power." However, in fact, the electric vehicle's entire electric vehicle' electrical motor, controller, wire carrier, charger and other systems are designed around the original battery parameters to match.

Once randomly replaced or adapted, the following risks may arise:
1. The voltage and current do not match, and the whole vehicle is overloaded for a long time.
Higher voltage and higher capacity batteries may cause the line to heat up at a consistently high load. Long-term use can easily trigger short circuits, aging and even fire.
2. Substandard panels lack effective protection
Some of the modified batteries used dismantled panels, recycled lead paste or low-quality materials of unknown origin that lacked complete quality control and protection design. Under scenarios such as high temperature, collision, overcharge, etc., it is more likely to occur problems such as plate sulphide, the loss of active substances, and leakage of the shell drum, and in severe cases, it may trigger an internal short circuit, abnormal heat, cause the battery to be scrapped early, and even bring safety hazards.
3. The charging phase is riskier
If the battery and charger lack a compatible communication and protection strategy, they are prone to abnormal heating, drumming and even combustion during charging. When the heat of some batteries is out of control, the reaction speed is extremely fast, while the chemical properties of lead-acid batteries are more stable, abnormalities are mainly manifested as puffs and leaking fluids, the processing window is more spacious, and there are very few open flame, but the risks cannot be ignored.
Batteries are safe, long new batteries are always in the core.
For a long-term battery, the battery is not only related to the range, but also to the sense of security of every ride.
Long Xin Battery has been focused on lead-acid battery R & D, production and manufacturing for 23 years. From the beginning of producing battery panels to now covering a full range of products, we have made a lot of long-term investment in product quality. From battery structure design to factory inspection, safety standards are strictly enforced in every step to ensure that the battery stablely matches with the entire vehicle system. The lead-acid battery electrolyte is a dilute sulfuric acid water solution, the threshold of heat loss is high, and the chemical properties are stable. Even in extreme short circuit situations, it usually only generates heat and smoke, and there is very little open flame.


We also want to seriously remind everyone about battery usage.
✅Please use a proper source factory battery
The official source factory batteries have undergone multiple safety tests and verifications and are completely compatible with the entire vehicle system. Long Xin Batteries, the source factory of lead-acid batteries for 23 years, is genuine, safe and reliable.
✅Do not privately modify batteries or battery crates
Even the so-called "professional modification" cannot guarantee the source of the battery, the process standard and the long-term stability. Many safety incidents often stem from an attempt to "feel it's fine."
✅Please check the official channels in time for battery abnormalities.
If you find a drum bag, abnormal heating, and a noticeable decrease in battery life, it is recommended to visit the official after-sales service channel in time for testing and treatment. Do not disassemble yourself, and do not buy used batteries of unknown origin.



Security is always more important than parameters.
Everyone wants their car to be better riding and more durable. But the premise of all experiences is that they are safe.
In those accidents that were publicly reported, many people initially simply thought that "it should be OK to change it." It wasn't until the accident that they realized the risks were far more serious than they thought.
Long Xin Batteries has been continuously investing in the construction of technology and standards, hoping to protect users' travel with more reliable products. We also hope that every user can attach more importance to battery safety.
Because of safety, there's no chance.
Long new batteries, focusing on lead-acid batteries for 23 years. Real material, safe and reliable.
