4A Automatic Li-ion Intelligent Battery Equalizer with 4.3-Inch Display Support 2-24S Lithium Battery Pack

Introduction:
- Balanced voltage automatic recognition mode: Automatically recognize the balanced voltage required by the battery, within the range of 2.0-4.5V.
- Widely applicable: lithium battery PACK factories, electric vehicle repair shops, personal lithium battery DIY, supporting 24 string lithium battery packs.
- The time required to complete a balance cannot be compared to that of power replenishment balance and energy transfer balance (power replenishment balance, energy transfer balance, discharge balance). Among these three balance methods, discharge balance is relatively safe and fast.
- Intelligent regulation, triple protection of over-voltage/low-voltage/reverse connection, ensuring that the balance is within the safe threshold throughout the entire process.
- Simple and easy-to-use one click start operation, with good results and fast speed. Supports mixed insertion (not starting from B1), with an external power supply of 12V 3A.
- 4.3-inch display screen, supporting switching between Chinese and English; Rich display content: each string voltage, total voltage, average voltage, highest voltage, lowest voltage, maximum voltage difference, balanced voltage, number of battery strings. The display layout is neat and the data is clear at a glance.
- Strong fan cooling, bidding farewell to traditional cooling methods.
- Reverse connection warning and prompt: It has reverse connection, overvoltage (greater than 4.5V), and low-voltage (less than 2.0V) protection functions. After balancing is completed, it automatically stops and a warning sound occurs to indicate that balancing is completed.

Specifications:
- Power supply voltage: DC12V

Package Included:
- 1 x Battery Equalizer

Operation Steps:
1. Power on and start the equalizer
2. The battery pack is wired according to the numbering of the equalizer or adapter board
3. Check if the display data on the screen is normal. If it is not normal, check the wiring or battery pack.
4. Press the button to start balancing, check if the balancing voltage is normal, and automatically stop after balancing is completed.

Precautions:
1. Due to the large balancing current, the balancing line must be thick enough, otherwise it may burn out or cause other problems.
2. B1 is the negative pole of the battery pack, which is the first string starting from the negative pole. It is prohibited to reconnect the battery during the balancing process.
3. During the balancing process, it is important to pay attention to any accidental touches on the lines of idle channels, otherwise the equipment or battery may be damaged.
- Tip: If one attempt at balancing does not achieve the desired effect, it is recommended to repeat the balancing process multiple times for better results.
