Lead acid battery to lithium battery

It mainly depends on the voltage of the original battery. If it is 3-4V, it can be replaced with a mobile phone lithium battery. After replacement, the original plug cannot be used. You can disconnect two wires from the lithium battery and use an old cell phone holder to charge it; If the battery voltage is not suitable, it cannot be replaced. Battery voltage can be measured with a multimeter. Some batteries are also marked with a mobile. phone battery voltage. Generally 3.7V.

It can be replaced with 48V10A lithium iron phosphate battery. The details are as follows:\x0d\1. Remove the battery from the electric car. There is a battery lock on the side of the car. Please use the electric door key to open it. Remove the battery. \x0d\2. Unscrew the screws at the four corners and carefully open the neckupper vercle. You can see that there are four 12V lead acid batteries inside. There is no bulge in the battery condition. \x0d\3. The battery circuit is connected in series. The red wire and brown wire are connected to the positive terminal of the battery. The red wire is connected to the discharge port of the battery box. above for the fuse. The brown wire is connected to the battery case. The positive terminal of the charging port and the blue wire are connected to the negative terminal of the battery. The thicker one is connected to the discharge port and the thin blue wire. The wire is connected to the negative terminal of the charging port. Don't forget the color of your battery wiring, which is relatively simple. \x0d\4. Next, use a soldering iron to remove the battery wires. Pay attention to prevent the battery from shorting during operation. \x0d\5. After removing all the old batteries, insert the battery into the lithium. When installing the battery, there are some small protruding plastics inside to separate the original lead acid batteries. The battery wiring is not soldered, but. the battery terminals are connected, then wrapped with electrical tape. \x0d\6. The wires are connected and you are almost done. You can sort out the wiring later, put the outer cover back on and tighten the screws. After load and commissioning tests, charging and use are completely normal.
