Guys,you're delivery and service were great! I was in a panic thinking that, though UPS had stated they had delivered the Battery Meter I'd ordered as a Christmas present for my Dad, it hadn't.

Wrong. With all the other on-line orders between myself and my wife this season, I had simply misplaced it. Great job, and so sorry I was thinking the worst, when in fact, you'd delivered the best!

I took advice from Orlbuzz and ordered when the ESR Meter was out of stock. It shipped on the day it was advertised to be back in stock..

My only criticism is that the resistance reading does not stay displayed long enough. I would prefer about 5 to 6 seconds.

A nice upgrade would be a USB port so that the readings could be transferred to my computer.
ESR Meter - A Must-Have Item for the Serious Electric RC Pilot Submitted by Andy Hoffer, Toronto, Canada on 2/5/2013

This is a superb piece of equipment and is an excellent value. Kudos to Wayne Giles for truly adding value to our RC experience with this elegant, well executed design. The ability to cut through all of the misleading manufacturer specs and descriptions for LiPo batteries and obtain a meaningful quantitative evaluation is a delight. The ESR meter is an excellent diagnostic tool for measuring and tracking the condition of the cells in a pack.

Congrats to Progressive RC for having the wisdom to carry this truly useful item and for their excellent customer service.

Best regards,

I bought this meter because I had some batteries that were discharging strangely, and I wanted some way to measure if they were good or bad. A bonus was having a way to watch my other batteries as they age.

The ESR numbers matched what I had expected from reading forums, and the higher resistance numbers did correspond to the packs that hit LVC early under load and ran hot:

It's so easy a monkey could use it, and the case seems sturdy enough. I took off one star for "value" because the price seems a bit high (almost 2 new lipos from HobbyKing) but I understand it's a niche product that doesn't ship in volume.

I think it does a great job, and would recommend it to anyone that wants to get the most life out of their lipos.

I agree with all the good already written. I will add a few notes.
Service from Progressive RC was excellent. I ordered when it was listed as backordered, the next day it was shipped, and the next day they were backordered again. I would advise placing your order and waiting.
I put 4mm solid bullet connectors inline so that I could use Deans and Jst connectors. I first used a Deans to Jst adapter. When I made a bullet to Jst connector, the mah dropped by 45! This meter and the forum where I discovered it have made me painfully aware of the limits of Jst connectors. I will be trying some mini Deans and make a bullet to mini Deans to check that next.
I have checked all of my lipos and logged the results at storage voltage. I look forward to following the usage results.
