4S Active Balancer with Voltage Display

Screen User Manual Version 2.0

The Chinese warehouse has updated its version

Other warehouses are gradually being updated

The 4S balancer has the finction of full-disk equalization without distinction andautomatic low-voltage sleep. The minimum voltage difference can be balanced toabout 0.01V, and the maximum equalization current can reach SA. When thevoltage difference is 0.1V, the current is about 0.5A (actually it will be related to thecapacity and internal resistance of the battery). When the battery is lower than 2.7V(ternary lithium/lithium iron phosphate), it stops working and enters sleep, and hasover-discharge protection function. The battery voltage display supports real-timedisplay of the voltage of the entire battery group and the voltage ofa single string, andthe numerical accuracy can reach about 5mV. This product is suitable for ternarylithium and lithium iron phosphate batteries.

The circuit board is sprayed with three-proof paint, which has excellentinsulation, moisture-proof, leakage-proof, shock-proof, dust-proof, corrosion-proofanti-aging, corona-resistant and other properties, which can effectively protect thecircuit and improve the safety and reliability of the product.

Why need balancer

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. 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.

Feature

Working voltage: 2.7V-4.5V

Suitable for ternary lithium, lithium iron phosphate,.

Working principle, the capacitor fit transfers the charge mover, the equalization board is connected to the battery, and the equalization is started. The original new ultra-low internal resistance MOS, 2OZ copper thickness PCB

Equilibrium current 0-5.5A, 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!

The quiescent current is about 12 mA. It is recommended that the battery capacity is 60-300AH.

With under-voltage sleep protection, the voltage will stop automatically when the voltage is lower than 3.0V, and the standby power consumption is less than 0.1mA.

Voltage Display

The accuracy of a single string is 0.001V, and the total voltage is 0.01V

Precautions for Use

During use, the design parameters and use conditions must be followed, and theparameters of this specification must not be violated. Otherwise, it is easy todamage the instrument and then damage the battery pack.

During use, the cable must be connected to the battery in the order of theinstruction manual, and then connected to the instrument after checking.

The product will generate a certain amount of heat during use, so avoid usingthe product in a high temperature environment.

If any abnormal situation occurs during use, please stop using it immediately.return it to the original factory or ask professional maintenance personnel forrepair.

This product has undergone a lot of reliability tests, and its reliability is farhigher than that of general equalizing equipment on the market. At the same time,the process of the battery cell must be guaranteed to minimize the occurrence ofcombustion.
