The LiPo balancer base has two main functions: accomodate each LiPo balancer element with a connector for the battery pack and incorporate a power switch to stop the charge process when one cell voltage is out of control. This base is intended to work with all the "constant current" chargers giving a very high protection grade in LiPo cells charging. In fact this module is not specific for the Universal Charger but is a very generic device.
The ALARM signal coming from the LiPo balancer element is in a "AND" gate with the others using the paralleling of the optocouplers output transitors. When at least on of these transistor is saturated, the gate of the power switch transistor Q1 is forced at 0.4V stopping the current flow. The zener diode prevent the gate overvoltage when the charger is used for high number of cells (above 20V).
In the Universal Charger (like in the Advanced) the stop of the current flow will give to the user the "Battery Disconnected" message.
Using the LiPo Balancer system the user can also recharge safely the LiPo batteries with a constant current charger (like the Advanced Charger) with some limitations. The charge process should follow these rules:

• choose the charge voltage greater than N(LiPo)cells*4.3V+0.5V
• choose a charge current as stated in the LiPo batteries user manual
• sets the delta peak to the maximum value
• sets the discharge threshold TOTAL value to N(LiPo)cells*3.0V

In this way the Advanced charger will deliver a constant current to the pack until the LiPo balancer will stops the process because at least one cell voltage will reach the ALARM threshold. In this way (without the constant voltage charge phase) the user can store in the cells about the 70-80% of the total capacity.

The PCB for the LiPo balancer base is easily adaptable to the number of the balancer element that the user uses: the silkscreen ha predefinet break lines for different number of cells.
