This module really represents a luxury version of the LiPoDiMATIC, and their basic functions are indeed identical.

This discharge monitoring module is certainly the year’s most important innovation.
Its purpose is to ensure that no cell in a LiPo pack suffers deep-discharging - far less reversed polarity - when being discharged in a model.
This small module is your guarantee of a longer effective battery life - especially if the pack consists of imperfectly selected cells - as it monitors the voltage level of each individual cell in the flight pack, and causes the motor to be throttled back if any cell falls below the permissible deep-discharge limit value.
The unit is simply connected to the balancer socket of your battery; the “servo lead” from the speed controller / governor is then looped through to the receiver.

Since the LiPoLogger intervenes directly in the throttle channel circuit, and - when required - shortens the throttle signal generated by the receiver, any(*) speed controller or governor can now be used safely with Lithium batteries in the simplest possible manner.

You can forget the arguments about the best average cut-off voltage per cell - should it be 2.5 volts or 3.3 volts?
With this module the weakest cell alone determines when the throttle signal is to be “throttled back”, or even whether the motor is switched off completely.

However, while the battery is being discharged, the LiPoLogger is also capable of storing cell voltages and the pulse width of the throttle channel in the micro-processor’s internal flash memory, where the data is retained (in non-volatile memory) until the start of the next recording process.

Plug-in auxiliary devices can also be connected to the unit, allowing it to read in and store motor current, motor temperature, motor speed, battery temperature and GPS data (altitude, speed, position).

The internal memory of 128 kB is sufficient to record data for one hour with 14 voltages
and an additional 8 typical measured data sets.
