4S 2A BMS Active Balancer Equalizer Lifepo4 Li-Ion Lipo Lithium Battery Energy Transfer Board Balance Module

Product advantages: BMS can reduce the number of strings, be compatible with other batteries, with a minimum of 2S, support extended series and improve parallel efficiency.
Applicable batteries: 3.7V battery pack and 3.2V lithium battery pack
It can be used to repair model toy batteries and can also be used in parallel with BMS long-term fixed battery pack, Because the chip setting logic is that the greater the voltage difference is, the greater the balance current is, and the long-term fixation will not cause damage to the battery.
Balance logic: take two adjacent batteries as a unit, and multiple columns are synchronized
Balance period: full voltage period (including charging, discharging and idle)

Balanced type: inductive active energy transfer
Balance efficiency: 94%
Balance current: 2000mA
Balance differential pressure: Less than 10mV
Trigger condition: adjacent differential pressure Greater than 0.1V
Balance cut-off: adjacent differential pressure Less than 0.03V
Low voltage protection: Less than 3V
Sleep power consumption: 500uA low power consumption, the battery can be idle for a long time
Three adjustable balance modes:
K1: keep active balance on.
M: When the battery voltage is lower than 3V, turn off active balancing and sleep.
K2: turn off active balance and sleep.
Cable length: about 480mm
size: 83 x 55mm
Material:ABS
colour:black
