Universal ESR Analysis Meter

  • Tool for measuring the internal resistance and C rating of a battery pack, or each individual cell within a pack

Availability: 12 in stock. In Stock




This new version of Wayne Giles' popular ESR meter now has all the features of previous models rolled into one - you won't find a more useful tool for battery analysis. From tiny single cells all the way up to a 6S 10,000mAh multirotor pack, this meter is ready to instantly provide objective data.

Internal resistance is a crucial aspect of a battery's performance, affecting the rate at which it can safely be charged and discharged. The ability to measure internal resistance enables you to compare batteries from different manufacturers with confidence rather than relying on often-suspect C ratings.

Our ESR (Equivalent Series Resistance) meter gives you just that ability - powered by the battery itself, the meter provides the internal resistance of an entire pack to a resolution of 0.3 milliohms or each individual cell to a resolution of 0.04 milliohms. With the added ability to enter the capacity of the pack being measured, you can now also find out the real C rating of the battery, based on the measurable resistance.

an awesome addition to any arsenalReview by motorguy 88
Looks great, wasn't expecting the XT60 plug. Thought a deans plug was installed , but no worries just had to dig a little deeper in the tool box. Works as expected and beyond, looking to many years useful service. A quality device for sure. Would whole heartedly recommend to anyone who wants to prolong their investment in their battery pool.Thanks for your insite in a field of few options or tools for lipo battery care and management. Thanks Again. (Posted on 12/18/2016)

Very easy to use and accurate Review by Simon
This meter already saved me $20 by identifying a defective battery that I just bought. I sent two pics of the reading to the seller and got a full refund! The meter is a great investment to keep my drones safely in the air with good batteries. (Posted on 3/19/2016)
Must have!Review by Gary
Great tool to have, for checking those suspect batteries of mines. Very accurate and easy to use. Helps me pick out Lipos that are near the end of their lifespan. Unit is also much smaller than expected, nice and light as well. Speedy shipping from Progressive as always, with adequate packaging and some candy! (Posted on 2/26/2016)
