Highlights
✦ Voltage Internal Resistance Battery Tester: FNIRSI battery tester can automatically test internal resistance and voltage value at the same time. The measured value can be used to determine whether the battery quality has decreased.
✦ TFT HD Color Display: The display adopts advanced color HD technology and excellent layout. Compared with traditional monochrome displays, it can present test results more clearly and vividly, greatly enhancing the user's measurement experience.
✦ Accurate Measurement: Adopts customized Kelvin four-wire connection method to avoid wire and contact resistance and improve measurement accuracy. Users can also manually adjust the voltage and resistance range.
✦ Wide Application Range: Suitable for all kinds of batteries. Car battery tester, household battery. It supports historical records and export data tables of historical measurements. View 8 sets of voltage and resistance values to batch select batteries.
✦ LED Display Handheld Meter: The resistance measurement range is up to 200Ω and the voltage measurement range is up to 100 V. The device must not be used with a DC voltage higher than 100V. Do not apply AC voltage under any circumstances.

UPDATE: Good news, the clamp test is compatible with 21700, but it's not immediately obvious, so I took some additional photos.
Turns out the lower tip is mounted on a fairly strong spring, and you just need to apply a bit of pressure to insert the 21700 format.
The clamp is amazing; I even managed to test the tiny 10180 format with it!
This multimeter is remarkable for its price and precision, especially when compared to a professional Fluke tool. While it falls short in terms of voltage measurement stability, it is highly precise when measuring internal resistance.
However, it’s not a full 5/5 rating due to the poor design of the new tester clamp. For instance, it doesn’t support the popular 21700 battery format, which is quite disappointing for a tool specifically designed for battery testing.
It’s unfortunate because just a few extra centimeters in the clamp design would allow it to accommodate 44 standard battery formats—something the SkyRC MC3000 charger achieves effortlessly.
To be fair, it is possible to insert a 21700 battery by removing the two adjustable screws at the back, which extends the tester clamp beyond its original limit (as shown in the photo). However, doing so applies unintended stress to the solder joints, which is not ideal.
On the other hand, the other tester probe is excellent, featuring spring-loaded tips that make measurements very comfortable. The only downside is its short cable, which prevents the probes from being positioned face-to-face horizontally, limiting usability in certain scenarios.
