Who assembles battery packs, recovers cells from old batteries or just wants to know how much their 18650 cells really hold needs reliable measurement. This 8-channel tester allows you to simultaneously check the internal capacitance and resistance of up to eight cells, and each channel works independently. The results and course of the test can be seen on the color display 2,4".

The device offers automatic mode, separate charging and discharging mode, adjustable charging current 500 – 1500 mA and discharge 500 – 2000 mA and adjustable cut-off voltage. Two 50 x 50 mm fans with heat sinks dissipate heat during long cycles. The tester is powered by DC voltage of 12 to 19 V with a power of 60 W through a socket of 5,5 x 2,1 mm. Note: The power supply is NOT included and must be purchased separately.

The most important advantages

• 8 independent channels 18650
• Measurement of cell capacity
• Measurement of internal resistance
• 2,4" color display
• Charging 500 – 1500 mA
• Discharge 500 – 2000 mA
• Adjustable cut-off voltage
• DC 12 – 19 V / 60 W power supply for purchase

Eight channels

Eight independent sockets allow you to test up to eight 18650 cells simultaneously, each with a separate result.

Capacity and resistance

The tester measures the actual capacity of the cell and its internal resistance, which is crucial when selecting cells for the package.

Color screen

The 2,4" display shows the results and the voltage and current graph during the test.

Adjustable currents

You can set the charging current in the range of 500 – 1500 mA, and the discharge current in the range of 500 – 2000 mA.

Three modes of operation

Selectable automatic mode, charging mode and discharge mode with adjustable cut-off voltage.

Active cooling

Two 50 x 50 mm fans with heat sinks dissipate heat when discharging cells.

More about the product

The inscription on the cell housing is one thing, and its actual capacity is another. Used cells, recovered from laptop or utility packages, as well as those from an uncertain source, can significantly differ from the declaration. The only sure way is a full measurement: charging the cell, controlled discharge and counting the energy given away. This tester performs these actions for you, simultaneously on eight channels.

The second important parameter is the internal resistance. The cell with increased resistance heats up faster, the voltage under load drops on it more strongly and works worse in devices with high current consumption. When building a package, it is worth combining cells with similar capacitance and resistance – thanks to this, the package works more evenly and individual cells are not overloaded.

Each of the eight channels works independently, so you can insert as many cells as you have and add more without interrupting the rest of the sockets. Automatic mode guides the cell through a full measurement cycle, and separate charging and discharging modes come in handy when you just want to charge the cells or prepare them for storage. Adjustable cut-off voltage allows you to adjust the test to the parameters of the cells.

You can set the charging current in the range of 500 – 1500 mA, and the discharge current in the range of 500 – 2000 mA. Lower values give a milder and more accurate measurement, higher values shorten the test time. On the 2,4" color display, you track the voltage and current graph, which allows you to assess the behavior of the cell during the cycle and quickly capture copies that deviate from the rest.

Discharging eight cells simultaneously generates a lot of heat. Therefore, the tester has two 50 x 50 mm fans with heat sinks that discharge them to the outside and stabilize the measurement conditions. The device measures approx. 310 x 102 x 42 mm, so it will fit on the workshop desk next to the soldering iron and cell welding machine.

The tester is powered by DC voltage 12 to 19 V with a power of 60 W through a DC socket of 5,5 x 2,1 mm. The offered variant does not include a power supply – for operation you need a separate power supply with a voltage in the range of 12 to 19 V, power of at least 60 W and a plug of 5,5 x 2,1 mm. If you already have such a power supply, for example from an old laptop, you can start working right away.

How to use

1. Prepare a DC 12 to 19 V power supply with a power of at least 60 W with a 5,5 x 2,1 mm plug.
2. Connect the power supply to the DC socket of the tester.
3. Insert the 18650 cells into the sockets, exactly according to the pole designation.
4. Select the operating mode and set the charging, discharging and cut-off currents.
5. Run the test and observe the mileage on the display.
6. When finished, read the capacitance and internal resistance of each cell.

Care and storage

Keep sockets and contacts clean by wiping them with a dry cloth. Make sure that the fan holes are not covered or dusty. After work, disconnect the power supply and remove the cells from the sockets. Store the tester in a dry place.
