FNIRSI Resistance Testers
FNIRSI HRM-10 Battery Voltage Internal Resistance Tester 18650 High-precision AC Acid Lithium Lead Car Battery Capacitor Tester
Questions and Answers
Up to what battery capacity can I use this device?
Please refer to the product manual.
Can we measure the internal resistance of a 300 Ah Lipo battery?
ALiPo battery at 300Ah internal resistance is normal less than 2.6 mOhm - you should use a manuel standard test stand for Lipo battery over 100Ah instead of a battery tester.
How can I set the date and time and choose the correct language?
Hello, does this device serve to measure the internal resistance of lipo batteries used in aeromodelling?
Yes.

It arrived earlier than declared. I made several measurements and it looks OK. Unfortunately, I have a problem uploading a photo to document the condition and the measurement results.

According to the description, arrived in France quickly before the expected deadlines. The device is well made and relatively accurate considering its price. To give you an idea, look at the photos taken during the resistance measurements of 1Ω 0.5%, 221Ω 0.5%, 40.95Ω 0.1% and the voltage of a 18500-type battery with the FNIRST HRM-10 and with the HP34401A. I did not take measurements with lead batteries, but based on the results, we can extrapolate. I recommend the HRM-10 as well as Banggood.

The goods arrived fine in perfect condition. I have already managed to do test measurements. I have no expectations at all for a laboratory device and I will not even show comparisons with laboratory instruments. Im an amateur and its perfect for my purpose. The workmanship is very precise and of high quality. Thank you and I wish a lot of success to both the manufacturer and the sellers.

Very nice, it measures very well. In the next version, inside the menu, there should be a way to delete the measurement history.

This low Ohm meter measures milliOhms fairly accurately and can offer a reasonable base-line for determining battery failure.
