Introduction:
As the battery battery cycle times increase, the battery capacity decay speed is inconsistent, causing the battery voltage to be seriously out of balance. The battery barrel effect will cause the battery to charge.
The BMS system detects that the battery has entered the overcharge protection in advance. In fact, only one of the batteries is full, or let The BMS system detects that the battery enters the over-discharge protection state, which is actually caused by over-discharge of one of the lower-voltage batteries.
At this time you need to use active balancer, after the device acts, each battery voltage reduces the capacity attenuation caused by the battery barrel effect and prolongs the problem. The battery pack has a service life.Are you looking for a compact and portable Balancer? Our new product, the 5A capacitor active balancer, can meet your various needs.

| Applicable string number | 4S | 6S | 8S |
| Applicable battery type | NCM/LFP | NCM/LFP/LTO | |
| Single string voltage range | 2V-5V | 1.0V-4.5V | |
| Static working current | 13mA | 20mA | |
| Operating voltage range | NCM/LFP: 2.7-4.2V LTO:1.8V-2.7V(6S/8S) | ||
| Undervoltage protection sleep voltage | NCM/LFP: 2.7V LTO:1.8V(6S/8S) | ||
| Balance voltage accuracy | 5mV (typical) | ||
| Balance mode | Active balance in which the entire battery group participates in energy conversion at the same time. | ||
| Balance current | When the voltage difference is about 1V, the maximum balance current is 5A, and the balance current decreases as the voltage difference decreases. The minimum balance start voltage difference of the instrument is 0.01V | ||
| Working environment temperature | -10℃-60℃ | ||
| External power | No external power supply is required, and the whole battery group is balanced by relying on the internal energy transfer of the battery. | ||
- Suitable for ternary lithium, lithium iron phosphate, lithium titanate.
- Working principle, the capacitor fit transfers the charge mover. Connected the balancer to the battery, and the balancing will started. The original new ultra-low internal resistance MOS, 2OZ copper thickness PCB.
- Max Balancing current 5.5A, the more balanced the battery, the smaller the current, with manual sleep switch, sleep current mode is less than 0.1mA, the balance voltage accuracy is within 5mv.
- With under-voltage sleep protection, the voltage will stop automatically when the voltage is lower than 2.7V, and the standby power consumption is less than 0.1mA.
-
The circuit board is sprayed with three-proof paint, which has excellent insulation, moisture-proof, leakage-proof, shock-proof, dust-proof, corrosion-proof, anti-aging, corona-resistant and other properties, which can effectively protect the circuit and improve the safety and reliability of the product.
Features:
- All group balance
- Max balance current 5.5A
- Capacitive energy transfer
- Fast speed, not hot
TFT-LCD Voltage Collection Display
Display can be flipped up and down through switches.
Connect directly to the battery and can be used in parallel with any balancer or BMS.
Displays the voltage of each string and the total voltage.
Regarding the accuracy, the typical accuracy at room temperature around 25°C is ± 5mV, and the accuracy at wide temperature range -20~60°C is ±8mV.
