HeltecBMS 1.2A 3S-17S 5A 3S-4S Active Battery Equalizer Balancer for Li-ion/Lifepo4 20S Equalizer Module BMS Energy Transfer

1.2A Inductive balancer Shipping guide:

The 1.2A inductance balance boards sent from China are all new models, please pay attention to the size.

Only Russian warehouse is also a random delivery of old and new models, which does not support designation！！！

New function:

Functions of the new balance board: a freewheeling diode is added. The freewheeling diode is often used together with the energy storage element to prevent sudden changes in voltage and current, provide access and protect the balance board. Another change is to use inductance with larger volume and power, which is conducive to heat dissipation.

Balance indication:

1. When the equalization light is on, the equalization work is turned on.

2. The equalization light goes out, the equalization circuit sleeps,

3. The equalization light flashes, the string indication is lost, or the circuit is faulty.

Principle of equilibrium:

This module is adjacent to the differential pressure equalization, and the adjacent battery voltage difference reaches 0.1V or more. The internal trigger balance is working until the adjacent battery voltage difference stops within 0.03V. There is an adjacent differential pressure when charging and discharging on the battery pack. Trigger equalization, the battery pack voltage error will be pulled back to the ideal value, reducing battery maintenance costs.

Technical Parameters:

Working voltage is 2.0V-4.5V, ternary iron lithium battery is common, lithium cobalt oxide battery is not applicable.

Equilibrium current:

Adjacent pressure difference is 0.1V or more (current is about 0.5-0.7A);

Adjacent pressure difference is above 0.2V (maximum equalization current is 1.2A or 0.8A , only 20S max balacne curent is 0.8A);

The smaller the differential pressure, the smaller the equalization current.

Feture

Working voltage: 2.7V-4.5V

Suitable for ternary lithium, lithium iron phosphate, lithium titanate.

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.

3S 4S can only used on Ternary lithium and iron lithium

Ohers String can used on LTO
