LiPo/Li-ion/LiFe battery balance Charger
 
Model:440B

440B is a 4 in 1 digital LCD balance charger / discharger/ balancer / cell monitor, it is for 2S-4S LiPo & LiFe battery.

2*2S battery can be charged simultaneously.

440B can charge your battery at up to 4.0A, 35W MAX. Discharge current is up to 300mA.

440B user's manual (309K )

As Balance charger, 440B will be very easy to use, it can charge the pack while balancing. Press the SET button set the charge current you want. During charge, 440B will display total battery pack voltage, cell voltage, charging time and charge current, battery gauge and so on.
As balancer, 440B can identify the voltage of each cell in your pack and bleed voltage off the higher voltage cells until they are equal to the lower voltage cells. At the same time, 440B will display total battery pack voltage, cell voltage, difference of cell voltage and running time.
As checking tool, 440B can detect and display total battery pack voltage, cell voltage, difference of cell voltage, and battery gauge.
As discharger, 440B can discharge your battery to the voltage you set. for example, if the cell voltage you set is 3.8V, the charger will discharge the battery to STORAGE status. During discharge, 440B will balance cells, and display total battery pack voltage, cell voltage, difference of cell voltage and run time. when the discharge over, the battery will resume balanced status.
 

Robust outer aluminum case
High-quality aluminum case is durable and very efficient to cool out the internal heat.

Perfect protection
The 440B has all kinds of protection for reversed polarity( input or output), low input voltage and over input voltage.
