Vapcell Internal Resistance Tester YR1030







This is a meter designed to measure internal resistance in batteries.







I got the meter in a cardboard box with specifications on the back.







The box contained the meter, 4 terminal probes and a manual.







The meter is in a standard box, i.e. not a box manufactured for the meter.









There are two connectors, a micro usb for charging the internal battery and a usb for probe connections.

Generally I do not like using usb connectors anything but usb connections, but in this case I do like it, because it makes it very easy if I want to make my own probes. The labels above the usb connector is signal names for the connections.







The probe looks home build, a usb connector with shrink wrap around.







The other end is two pogo pins in aluminium tubes with shring wrap around.

This means I can easily make new probes if I damage the supplied ones.

The dual pogo pins means that it uses true 4 terminal measurement, there is no errors from contact or cable resistance.







The display shows the battery status, resistance and voltage.

Both voltage and resistance can be in manual or auto range.







There is a couple of buttons:

Power is used to turn on/off the device.

Hold/Zero is used to freeze the ohm reading or zero the ohm reading

Range R is used for manual range select on ohms (20m, 200m, 2, 20, 200, auto).

Range U is used for manual range select for volts (2V, 20V, 28V, Auto).







In addition to this Power can be used to activate the menu system. Here Power is the enter key, Hold is the escape key and the two range buttons are up/down.

In these menus a grading system can be setup, this will make it easy to sort batteries according to voltage and internal resistance in 3 bins. It is also possible to calibrate the meter and set some preferences.







Measurements







Due to the way the meter works it do not need a battery to measure resistance, but can be used as a general milliohm meter.

Here I am testing on some resistors and comparing to a very precise meter.

The precision is very good.







The same with voltage, again the precision is very good.







The meter is using a 1000Hz sinus for measuring the resistance



The meter uses 1uA when off and 60mA when on without background light.







Tear down







I had to remove four screws to open it.



































Conclusion



I like this meter, it is very useful for a lot of stuff, not only batteries. It can measure the resistance in a switch, a tail spring, a atomizer and a lot of other stuff.

When used to measure resistance it will give same value as an ordinary DMM except for much better resolution at low values. On batteries the value cannot be compared to the values chargers measures, but usual the datasheet value is measured this way.







Notes



I got the meter from Vapcell.



As reference I used my Keithley DMM7510, it can do 4 terminal ohm measurement.



Internal impedance/resistance of batteries

So it sends a known current through the test piece (spring or switch) and measures the voltage drop? Sounds like it could be a handy device, but how does it work with measuring cell IR?

3

It uses a AC current, this way it can ignore any DC value.

Thank you for this review. Does anyone know where this product can be purchased? I’ve only seen it on Alibaba, with a minimum order quantity of 10 pieces.

Is this the same item but not the vapcell name?

Edit the link

The link do not work, but if it looks the same it is probably the same.

I want to get one. Just can’t find it :frowning:

I edited my link as well the link in the quote.

It was from the NO.1 COM store.
It looks like yours and if you click the item description he have pictures of additional probes but it’s not clear for me what’s included in that buy link.

I sent a message to the seller if the additional probes is included and if they are included it’s probably the cheapest buy if you want the extra stuff.

Let’s see what he responds.

.

Meanwhile waiting for a response for that seller.

This seller have the complete set for a few dollars more but with options so you know what u get.

Edit: put in a link for next best deal while waiting for a response from that other seller.

Ok. The seller have responded.
It wasn’t the full set for that price. Then he wanted 86$ for the full set.

So the changjin zhong’s store have the best price at 65$ for the full set.

So would this be a good IR tester tool for a first timer like me using something like this?

I have the miboxer C4-12 charger but the mohms readings on mine seem to bounce around quite a bit on the charger with cells. I just want something accurate at a good budget price.

Thanks,
Mike
