The XH-M240 module measures the capacity (mAh), stored energy (mWh) and voltage (V) of a single Li-Ion18650 cell. It can be powered by an external 5-12V source or an 18650 cell (the second power slot on the module). After the test, the measurement result is displayed on the LED display until the device is reset.


Technical parameters:

- model: XH-M240
- working voltage: DC 5V-12V or Li-Ion cell 18650
- standby current: 5-7mA
- discharge current: 500mA
- load: resistance 8ohm 10W
- voltage measurement accuracy: 0.1V
- accuracy of capacity measurement: 1mAh
- energy measurement accuracy: 1mWh
- working temperature: –25°C~85°C
- humidity: 5%~95%RH
- dimensions: 110×80×25mm
- general properties of Li-Ion cell 18650:
- nominal voltage: 3.7V
- voltage to stop discharging: 2.75V
- charging recovery voltage: 3.24V
- recommended charging voltage at the moment of full discharge (U=2.75V): 3.5V
- recommended charging voltage when fully charged: 4.2-4.35V
- max. terminal voltage of the cell: 4.35V
- excessive discharge shortens the life of the cell


Instructions for use:
1) Connect working voltage DC 5V~12V from XH2.54-2P white socket or insert 18650 power cell into the left battery holder.
2) Install the tested 18650 cell into the right battery holder.
3) Turn on the power switch. The display shows the current voltage of the cell under test.
4) Press the + or – button repeatedly to set the voltage to end discharge. The recommended voltage of the measured cell to end the test is 2.75V. By simultaneously pressing the + and – buttons for 3s, the factory parameters are set.
5) A short press of the left button starts the article test. Then the LED indicator D3 located above the start button lights up.
6) By briefly pressing the second button from the left, the current display can be switched to
mAh / mWh / V.
7) Press the left button for a long time to clear the measured values.
8) The module ends the discharge-testing of the cell after reaching the set voltage to end the test. After that, LED D3 starts flashing (it lights up continuously during measurement). The LED display shows the measured capacity, energy and voltage of the cell.
9) Estimated measurement time: Discharge current is 500mA. If the cell capacity is 2000mAh, the measurement time will be approximately 4 hours.

The product is not an independently functional unit, it requires professional assembly.
