12v 100A 60a Smart Battery Charger 30A 20A 40A 50A Fast Charger with Adjustable Current 100V-240V for Lifepo4 Lithium Battery –

Warning:

1: Do not adjust the charger voltage during the charging process, as it may damage the battery< br>

2: The voltage on the charger display screen fluctuates, but in reality, the battery is charged at a constant voltage< br>

3: The screen displays the actual current value, which is not the current value you adjusted. Please consider the battery capacity and the maximum BMS current value for the current size. In the later stage, the current will decrease, and when the battery is fully charged, the fully charged current is 0.<br>

4: If you want to measure the maximum current, it is recommended to discharge the battery before testing< br>

5: Charger buyer, please refer to the detailed operation video or text introduction< br>

6: Be careful not to connect the positive and negative poles in reverse. The correct connection method is+TO+, – TO -. Disconnect and damage the charger within 10 seconds of reversing the connection. Over time, the motherboard will burn out< br>

7: To extend the lifespan of the charger. The voltage of the charger is 220V, and the maximum recommended current is 90%. For example, 60A is most suitable for adjusting it to around 54A. The maximum recommended voltage and current for 110V are 80% and 70%, respectively< br>

8: As long as the charger is connected to the power supply, the fan will start until the power is disconnected. Mind buying carefully< br>

9: If you have any questions, please contact customer service< br>

10：3-stage charging (CC, CV, TC）

The first stage of constant current and constant voltage charging is charged with a constant current; When the voltage reaches the predetermined value, it enters the second stage for constant voltage charging, during which the current gradually decreases; When the charging current drops to zero, the battery is fully charged. This is the most commonly used charging method for lithium batteries,

So the charger won’t always display the maximum charging value.

For example, if you use a 100A charger to charge a battery, if the battery is at 80% charge, the charger will only display 20A instead of 100A, and it will be 0 when fully charged,

    This connection 60A Spanish overseas warehouse has goods in stock. European customers can choose to purchase from the Spanish place of shipment, and other connections are shipped from China. The quantity is limited.

Do not adjust the charger voltage during the charging process. The voltage of the charger itself will fluctuate,

And it is normal to charge the battery with a constant voltage. When the battery is fully charged,

The current on the charger display screen will be displayed as zero or close to zero.

As long as the charger is connected to the power supply, the fan will start until the power is disconnected.

Before adjusting the voltage correctly, please do not connect the charger to the battery

Welcome to the factory directly operated store, capability.Li is our brand, we have lithium batteries, lithium iron phosphate batteries and other processes. We accept custom batteries and we cannot update all items here. If you have other requirements, please contact the customer and tell me your requirements (power/battery capacity/voltage/weight/continuous discharge current of external equipment), we will customize it for you. Thank you for coming, thank you!

We have independently developed a new charger with anti reverse function for large display screens.

Special instructions for 60A /85A chargers: first plug the charger into the power supply—–look at the voltage—adjust the voltage—–then connect the load—–and then adjust the current.

Step1: Do not connect the battery to the charger, turn on the power, adjust the voltage knob to adjust the voltage, refer to the voltage display at the top of the display, (4S lifepo4 battery 3.65 v*4=14.6V, 3S lithium battery 4.2v *3=12.6V), adjust to the voltage you need (you can adjust the voltage in combination with a multimeter. The display will have a small error.).

The usage method of a 40A charger is as follows: First use: Connect the power supply first, adjust the voltage you want, then connect the battery, the charger display screen will turn off, unplug the power plug and plug it in again, it will display normal charging, and adjust the charging current.

Second use (the voltage has been set for the first time, no need to set it again later) — Connect the battery first (it is important to protect the charger) — Then connect the power — Follow the second step for all subsequent uses.

Do not adjust the charger voltage during charging. The voltage of the charger itself fluctuates, and constant voltage charging of the battery is normal. When the battery is fully charged, the current on the charger display screen will be displayed as zero or close to zero. The display screen is a bit inaccurate. If it is an LFIEPO4 battery, it becomes more difficult to charge it later on. The display screen shows 0, and the multimeter may still have weak current charging. This is virtual electricity. This is a normal phenomenon. If you don’t understand, please consult customer service

To extend the lifespan of the charger. Charger 220V voltage, maximum recommended current is 90%, for example 60A, it is most suitable to adjust to around 54A. The maximum recommended voltage and current for 110V is 80%, and the maximum recommended voltage and current for 100V is 70%

Attention: After adjusting the voltage and connecting it to the battery. Do not adjust the voltage during the charging process. The voltage displayed on the display screen is the voltage reached by the battery. After being fully charged, the voltage displayed is 14.6V/12.6V. The battery has a fully charged current of 0A

The voltage of this charger is adjusted with screws, which is more conducive to voltage fixing, and will not change the voltage due to accidental collision. Voltage regulation can be combined with a multimeter.

Q: How to use the charger?

Answer:

1. Connect the AC power cord first, turn the current potentiometer clockwise, the screen will display,

2. Then adjust the voltage potentiometer to what you need, for example, adjust lifepo4 to 14.6V。

3. Connect the battery, then adjust the current potentiometer to the required current。

Q: Will the charger automatically stop working when the battery is fully charged?

Answer: After the battery is fully charged, the charger will no longer charge the battery. The current displayed on the screen is 0, but the fan and display light will remain on. As long as the power is connected, the fan will start working. It is recommended to disconnect the power cord and battery charging interface after fully charging。

Q: If the power cord is thin, will there be a danger of heat or fire?

Answer:Our power supply is a custom wire, which is pure copper wire, it will not affect your use, don’t worry too much。

Q: Can the output line withstand such a large current?

Answer: We are all strictly tested at full current, use it with confidence。

Q: Why does the voltage drop after we connect the battery, do I need to adjust it again?

Answer: After the charger output is connected to the battery, the voltage displayed on the display is the voltage between the battery voltage and 14.6V, and there is no need to adjust it. As the battery is slowly charged, the voltage will rise。

Q: Why can’t the voltage of my power supply adjust without the battery being connected?

Answer: In this case, there should be a problem with the adjusted resistance in the charger. At this time, customer service needs to solve it. It is necessary to replace the voltage and current control board inside. It is easy to replace it yourself.

Q: Why is the charger noisy？

Answer: Because it is a high-current charger, the fan needs to run at high speed. We use a better fan, but in order to dissipate heat, it is inevitable that there will be a little noise, but the noise decibel is within the acceptable range.

Q: If the positive and negative poles are reversed, will the machine burn out?

Answer: If it is found that the positive and negative connections are reversed, remove it immediately. At this time, the probability of the machine being damaged will be very small. If it is reversed for a long time, it will cause the power supply to burn out. Be careful when using it.
