The electric car's lead-acid battery has been in use for a long time, it's shrinking, it's not charging, it's switching to biadi's lithium battery, and it's being bludgeoned by the maintenance shop owner: "the controller must be replaced, or the battery will burn, it won't be safe, and it'll cost hundreds more to open the door? I'm telling the truth today: as long as the voltage is the same, in exchange for the lithium biadi phosphorus battery, the original car controller is not changed at all, the merchant is asking you to change the controller and is simply trying to make more money

But let's not think that changing batteries is the simple way to break old clothes, that the controllers don't have to change, that they don't have to move anything, that they have three sets of accessories, that they can't be replaced, that they have to be replaced, that they can't be replaced, that they can't be replaced, that they can't be replaced, that they can't be replaced, that they can't be replaced, that they can't be replaced, that they can't be replaced, that they can't be replaced, that they can't be replaced, that they can't be replaced, that they can't be replaced, that they can't be replaced, that they can't be replaced, that they can't be replaced, that they can't be replaced, that they can't be replaced, that they can't be replaced, and that they can't be replaced, that's confirmed by the fact that the latest version of the electric car in 2026, the rules and the master's work experience, and that they can't be saved with a lot。
Let's get to the point: why not switch the controls with the voltage for biadi lithium batteries
A lot of drivers don't know the mechanics of electric cars, and when the merchants say, "no control matches," they pay for it, so let's get the core logic straight, and never again。
The central function of the electric vehicle controller is to control current output, protect batteries and electric generators, which, in the white word, is the electric vehicle's “wirekeeper”, which is not directly related to whether it works, whether it is critical to see whether the voltage matches, whether the battery is lead acid or lithium, or whether it is a biadi brand。
Lithium phosphate batteries provided by biadi to electric vehicles are produced at national standard voltage, with common 48v, 60v, 72v and original lead-acid batteries being identical:
• 48v lead acid batteries, working voltage 42v-54. 6v; 48v biadi lithium voltage, working voltage 41v-54. 6v, near overlap
• 60v lead acid batteries, working voltage 52. 5v-67. 5v; 60v biadi lithium voltage, working voltage 52v-67. 2v, with minimal difference
As long as you do not self-lift the voltage (e. G. 48v for 60v, which is an irregular modification), the original vehicle is fitted to the control of the corresponding voltage, fully compatible with biadi lithium batteries, whether discharge, charge or protection logic, and can work normally without burning batteries or engines。
The maintenance masters who have been in business for more than a decade have made it clear that the formal biadi lithium batteries bring their own bms smart protection systems, which are better protected than lead-acid batteries, and can reduce the control burden. As long as the voltage is right, the controller is used in the original vehicle, there is no need to replace the so-called “lithium electric controller” with 300-800 dollars, which is a commercial twirlway that must be kept in check。
It's important to remind you that these three have to be changed, not on the road
The controls will not be changed, but the three components, which are the “spectrums” of the biadi lithium batteries, will not do so much, not because the merchants want to make more money, but because of the safety and battery lifetime, which were explicitly required to be replaced simultaneously in 2026 in the case of electric vehicles。
One: specialized lithium battery chargers, never using original car lead acid chargers
This is one of the most critical and easy to ignore: the original lead-acid charger, who is determined not to use the lithium batteries of biadi, even if the interface can be plugged in, is the first taboo to switch to lithium。
The charge logic and voltage curve of lead-acid and lithium batteries are completely different: lead-acid chargers are constant current chargers and are filled with non-automatic power outages, while biadi lithium batteries have strict charge voltage, current limit, need dedicated lithium chargers, full of automatic post-firing, steady pressure protection。
If lithium biadi is charged with lead-acid chargers, light leads to battery inundation and direct water reduction of 30 per cent for the continuation of the flight, heavy overstretching, damage to the inner core of the battery, and even the risk of short circuits and fire, a lithium biadi battery can move thousands of pieces as a charger is damaged and too expensive。
The regular battery-replaced door store will be accompanied by a biadi lithium charger with the same voltage, which will be clearly marked as “lithium phosphate” and fully matched with the battery voltage, if the merchant asks you to buy the charger, or if you continue to use the original car and turn around directly, which is not responsible, but rather the pothead。
Second: battery-specific connections + safes, the original circuits need to be changed
It is also a big mistake for many drivers to change batteries, focusing only on the batteries themselves and ignoring the connection lines. The original lead-acid batteries are wired, lined, small electrical currents, which are more energy-intensive and more electrically discharged than the audi lithium batteries, and the original circuits simply cannot withstand。
The long-term use of fine wires for lithium electricity, the heat and heat of the line, the acceleration of the ageing of the line, the melting of the insulation layer over a long period of time, short-circuit fires, especially in old electric vehicles, which take three or five years and have problems of aging themselves. Lithium electricity must be replaced simultaneously with coarse and pure copper-coated connections and equipped with adequate safes。
Specialized connection lines are thicker, pure copper, conductive, unheated, the safe can automatically melt when the current is too large and short, and the battery and the entire vehicle are protected at a cost of several dozen dollars, but the security of the circuit is completely eliminated。
The third type: the electrical display instrument for lithium is not allowed to damage batteries
The electrostatic instrumentation of the original lead-acid battery is based on the voltage decay logic of the lead-acid battery, which, with the replacement of the biadi lithium battery, is not the same as the voltage decay curve, which raises the problem of inaccuracy: it is clear that there is 50% power, and the instrument shows no electricity; or when it's full, it's out of control, and there's no way to judge the real renewal。
More importantly, the failure to display the instrument makes the owner of the vehicle liable to miscalculate the amount of electricity, is prone to overcharge, and lithium batteries are the most vulnerable to overcharge, and, once emptied, the core will be damaged directly, the battery's life will be significantly reduced, and even it will end up dead。
The conversion to a lithium-specific electromechanical instrument that shows the true amount of electricity and voltage of the lithium bitter battery, gives you a clear idea of what remains, avoids overcharge, protects the battery's core, prolongs the battery's useful life. This instrument is not expensive, several dozen to 100 dollars, replaces the battery with a different battery, and saves more effort。
In the case of biadi lithium batteries, do not step on these pits
1. Refusal of private voltage: 48vs for 60v lithium power are irregularly modified, not only to change the controllers, to move the electrics, circuits, to be checked for direct attachment to the vehicle, but also to have a significant security risk
2. Don ' t buy low-cost batteries: they look cheaper than the lithium batteries of the adi, but they're old, without quality assurance, and in less than half a year, they have to buy a whole new, secure battery
3. Battery fixation: biadi lithium batteries weigh less than lead acid and must be installed firmly to avoid shaking, moving, damaging lines and battery casings in the line
4. Quality assurance should be clear: the real biadi phosphorate lithium battery, which is for two to five years, is replaced by a business that will write the term of the warranty, the terms of the sale on the receipt, and avoid subsequent pilfering
The real case: if you don't listen, you'll spend a lot of money
The owner of the car, wang master, replaced the electric car with 60 v-biadi lithium batteries, did not change the charger, did not change the line, continued to charge the original car with lead acid, which was filled three times, the battery was packed and sold to the merchant, who said it was caused by irregular charging, was not covered by quality assurance, and more than 1,000 pieces of the battery were scrapped, and the battery was replaced with a special charger and line, which cost more money。
Also, ms. Li, the owner of the car, changed the lithium-free meter, the amount of electricity showed to be irregular, often on a half-way basis, and then returned to normal with the excessive discharge, which caused the battery to shrink significantly and eventually spent money changing the meter。
All of these examples show that the controls can be saved without the money to be exchanged, but the three spare parts that should be replaced will not be saved, safety and battery life will be the most important。
Compliance alert: batteries need to be changed to meet national standards, and no changes should be made
In 2026, the safe management of electric vehicles became more stringent, and lithium-replaced batteries must comply with national standards:
• battery voltage shall be consistent with the original vehicle and shall not be modified or pressured
• selection of a 3c certified biadi lithium battery with a formal brand and rejection of three products
• replacement of qualified regular stores and maintenance of purchase vouchers and quality assurance instruments
It is not only safe and secure to change compliance, but also to go on the road and not to worry about being checked that it is essential to ride peacefully。
Summary
The core truth must be kept in mind: the original vehicle controller is completely free of charge and is not being misled by the merchants in exchange for the lithium lithium battery battery battery; however, the lithium battery battery battery battery battery battery, the lithium battery battery battery battery battery battery, must be replaced simultaneously。
The essence of changing batteries is to keep them up, to make them easier to travel, not to waste money, to bury safety risks, and to keep businesses open, so long as we understand the principle and know the bottom line, we can avoid all pits and spend the least on safe, durable lithium batteries。
The safety of electric cars is always the first priority, not to save dozens of dollars, ignore critical accessories, and not to be deceived by the false propaganda of merchants and spend the wrong money. The knowledge is passed on to the friends who ride electric cars around, so that the batteries don't get stuck, so that they can ride home safely。
