Ternary/iron-Lithium General High-Precision Active Balance Board Energy Transfer Board 3 Strings 4 Strings 5 Strings 6 Strings

The working principle of active equalization is that high-voltage batteries automatically charge low-voltage batteries. Iron is an energy transfer type and generates very little heat. Both iron-lithium and ternary lithium are common.

Capacitor active balance: A specially customized control chip is used to achieve a high-precision balance of ±5mV, with a balance current of 3-6A.

(Note: Start wiring from 0V in order, if you connect the wrong wiring, it will burn the board!)

Description:

3~4, 5~6 series 3A/6A capacitor active balance:Scope of application: all ternary lithium batteries and iron-lithium batteries are universal, and more than 5 strings support lithium titanate batteriesThe 3A version is suitable for battery packs above 10Ah, and the 6A version is suitable for battery packs above 20AH.

Product size: 47*28*17mm(43A), 68*46*17mm(6S3A),47*35*25mm(4S6A), 68*52*25mm(6S6A),

Product weight: 16g(4S3A), 27g(6S3A), 25g(4S6A), 42g(6S6A),

Working voltage (single cell): 3.0V~4.3V, over-discharge protection voltage: 3.0V<Within this voltage range, the equalization board will always work unless it is manually turned off>

Standby current: 0.1ma~0.2mA (when the voltage of a single cell is lower than 3V, or when the switch is in the OFF position)

Quiescent current: 4S3A version: 4mA4S6A version: 8mA6S3A version: 5mA6S6A version: 10mA Balance current: 3A/6A (The actual working current is related to the battery voltage difference and battery internal resistance. The greater the voltage difference or the smaller the internal resistance, the greater the balance current.

AB solder joints: When using lithium titanate batteries, you need to short-circuit the AB solder joints and then workThe voltage becomes 2.0V~4.3V, and the over-discharge voltage becomes 1.5V.

Note!! When using a ternary lithium battery or a lithium iron battery, the two solder joints A and B must not be short-circuited, otherwise the battery will be over-discharged.

Note 1: Before wiring, turn the switch to the OFF position to turn off the machine, and repeat the confirmation that the wiring sequence is correct.Turn the switch to the ON position and start working.OV is the total negative pole of the battery pack. It cannot be connected to the wrong wire, the wrong wire will burn the chip!

Note 2: Use copper wires above 0.75 square millimeters (17AWG, 18AWG) to connect,The thicker the cable, the better, and the shorter the better.

Note 3: When working with high current, a slight noise is normal.After connecting the battery for the first time or shutting down for a long time, the startup is slow, please wait patiently. When the switch is turned OFF, the indicator light will not go out immediately because the capacitor has residual power.There is a flying wire on the back of the 6S version to solve the BUG, the next version will be improved.

Note 4: The 4S version can be compatible with 3 or 4 strings of batteries,6S version, compatible with 5 strings or 6 strings.
