SUNKKO BAL-4S-1A Active Battery Balancer 2-4S Battery Equalizer for Ternary Iron Lithium Battery

Features:

- BAL series for zero loss equalization
- Non-energy-consuming energy transfer equalizer board
- 1.2A high current for fast equalization; 1MHZ high frequency
- The balance board can be connected with a battery protection board to be used inside your battery pack
- Zero energy consumption and energy transfer for equalization: By detecting the unbalanced voltage difference between adjacent series battery, the high voltage is transmitted to the low voltage to achieve voltage balance between the battery strings. Energy saving and environmental protection
- The minimum balance voltage value is 0.03V: the actual balance current is related to the voltage difference between the cells. The greater the difference, the greater the current. At the same time, the equalizing current is also related to the length of the connecting cable and the cross-sectional area of the wire. Connections are made with short and thicker quality wires. The minimum balance difference is related to the internal resistance of the battery pack and the resistance of the connecting cables. The greater the internal resistance and resistance, the greater the balance difference
- A new way of balancing lithium battery packs: balance the voltage difference of the battery pack at all times to prolong the service life
- Suitable for iron lithium battery pack and ternary lithium battery pack. Can be installed in the battery pack to continuously equalize voltage difference
- 24-hour uninterrupted detection: The equalizer can automatically detect the uneven voltage value between adjacent battery strings. When the detected voltage difference value ≥ 0.1V, the chip automatically balances the work continuously→intermittent work→stop work mode, which can achieve accurate balance difference ≤0.03V
- Palm size enables easy application
- Safe to use. With efficient chip heat dissipation and equidistant heat dissipation layout, the board can be connected to battery pack for long-term anti-microduo balance. A fixed-term repair balancing can be done for the battery pack. The board does not get hot during daily work, because the heating temperature is only 27°C
- Intelligent detection, automatic repair. It can automatically detect the voltage difference between adjacent batteries online, and start to balance the voltage when the quantitative difference is reached. No need for human management, since it can be used after connecting the balance board. Automatic detection; high current equalization; automatic repair
- Solve the following problems: short battery life, power failure, and battery not fully charged
- The circuit adopts waterproof, dustproof and anti-leakage paint to better protect the circuit and improve the reliability and safety of the circuit board
- BAL-4S-1A: 2.54mm interface
- Compact independent unit: all units have the same link layout to ensure uniform energy transfer performance and prevent mutual interference between units and energy radiation loss caused by layout dispersion
- LED indicators: The LEDs light up to indicate that the energy transfer balance is in progress between the two batteries; The long-light LEDs indicate stable equalization work; the intermittent LED flashes indicate that the equalization work is about to end; the LEDs are off to indicate the end of the equalization

Read before Purchasing:
- It is mainly used for ternary lithium and lithium iron phosphate battery packs to balance the voltage of each string of batteries. Before purchasing, please check whether the battery pack voltage difference is too large to cause poor battery life. If your battery is damaged, or the internal resistance is too large, starved, flooding, etc., the equalizer board is not for your batteries.
- The board will automatically turn on the equalization when the adjacent voltage difference exceeds 0.1V. No external power supply is required. Please check whether the battery voltage difference is higher than 0.1V before purchasing.

Precautions for Use:
- Before the cable is removed from your protection board and connected to the balance board, make sure that the line sequence of the protection board is the same as that of the balance board. Reverse connection and wrong connection will damage the balance board and battery, so be careful.
- When using for the first time, the greater the voltage difference, the greater the equalizing current, and the maximum equalizing current can reach 1.2A. At this time, a large amount of heat will be generated. It is recommended to use it in a ventilated environment.
- This equalization board is a maintenance accessory. Customers who need to assemble it inside the battery pack need to equalize it externally first to reduce the voltage difference, and then weld a set of cables for insulation protection. Before connecting to the equalization board, you need to use a line sequence test board or T-616 analyzer or multimeter to check to ensure the correct line sequence, otherwise serious consequences will be caused due to wiring errors.
- During the circuit test process, the customer must conduct on-site visual monitoring to prevent the occurrence of unsafe factors such as short-circuit, over-voltage, and over-temperature, you should immediately terminate the test and disconnect the circuit and give us immediate feedback. We are not responsible for any safety accidents and losses that may be caused by various misuse of this product.
