Meter the Internal Resistance of the battery as a whole, or each individual cell

Finally, a full-scale-production IR meter, readily available from a trusted source at an affordable price! The Revolectrix IR Meter is capable of instantaneously displaying Pack Voltage down to the cell level as well as Pack DC internal resistance (DCIR) and the individual cell DC IR for any Li chemistry battery pack within a nominal DC voltage range between 7.40V and 26.10V. The Revolectrix IR Meter utilizes true Kelvin 4-wire current sensing and may be considered a laboratory-quality instrument due to its unparalleled accuracy when compared to other competing R/C brands.


  • Simple, intuitive, single momentary push button user interface
  • Just connect a battery and toggle through various screens to verify the state-of-charge and health of any Li chemistry battery pack
  • No need to configure or select presets; just plug and go!
  • Always know the voltage of a pack down to the individual cell level before taking to the air!
  • See instantaneous and highly accurate DC IR for every cell; the best indicator of pack health
  • Know when it's time to retire a pack by watching for, and logging trends in IR over time
    * Please note: all specifications and features listed above subject to change without notice.

Revolectrix LiPo Battery Internal Resistance IR Meter (LiPo Only)
This is a must-have tool to inspect your LiPo batteries. I spent many hours researching battery internal resistance meter options and there are not many. Some come as part of a charger, but from what people say they are not reliable and produce strange results and not consistent even on the same battery. Revolectrix Meter has one purpose, and it does it well. I just checked all my 8 batteries in one minute and can tell if any cells are bad or getting bad. In my case, they all seem healthy at a nice 5-6ohm resistance. The price seems like much, but I think the tool is price fair for a small batch product with good quality control. I highly recommend this meter and hope companies like that stay in business.
