Lipo Balance Charger (320B)

Product Description

320B Charge current up to 1A, 15W, for 2-3 LiPo cells

Built-in balancer for LiPo cells
The CY-320B has a built-in individual cell balancer. LiPo batteries are automatically balanced during charging ensuring that when the battery is fully charged it is also properly balanced.

High power and high performance circuit
CY-320B employs the high efficiency circuit. As a result it can charge 3 series of lipo batteries with maximal current of 1.0A. And the case is only 75*44*18.

Input power monitor
To protect the car battery using as input power from being damaged the input voltage always monitored. If it drops the 10.0V the charging process will be ended automatically.
At the same time, when you use the AC adaptor or transformer as input power, if the input voltage is more than 18V the charging process will be terminated to protect the CY-320B from being damaged.
Reverse polarity and short circuit protection( input and output)
Over charge and Over current protection
Light and attractive AL alloy case
3 LEDs display each cell in balancing
1 LED indicate the charging status, RED for charging, Green for full charged.

Operating instructions
Connect the DC power or AC Adapter (12.5V, up to 1.2A) to the CY-320B. The charging LED will on for 1 second and then OFF.
Connect the 2S or 3S battery pack to the CY-320B, Charging LED should be RED, the charger start to charge.
If the battery pack is un-balanced, the corresponding LED will flash, the charger is balancing the battery pack.
When the charging LED is GREEN, and all balance LEDs are off, the battery pack is fully charged and balanced.
While charging, the built-in balancer will monitor the voltage of each cell of the battery pack and control the charging current feeding to each cell to balance the voltage.

Warning and Error message
During charge, any cell voltage is lower than 2.7V/cell, CY-320B will charge at 100mA, the charging indictor blinks and the beeper sounds.
When any cell voltage is between 2.7-4.2V, the charge will charge at 1A (Constant Current mode).
When any cell voltage reaches 4.2V, the charger will charge at Constant Voltage mode.
LED indicator.
Charge LED on and then off: The charge ready to charge.
Charge LED: RED, charging.
Charge LED: Green, fully charged.
Charge LED: RED flash, Short circuit or Reversely Polarity Connection on input and output.
Balancing LED: Flash, the battery is unbalanced.
When the battery connected to the charger, if the charge LED flash RED, please check the battery polarity and the battery voltage. If the battery is over discharged, the charge will not work and the RED led flash.
