I won't post IR data for many reasons
Do we dare speculate what the other reasons might be?

I could see people measuring IR with crappy chargers and at odd temperatures and then wanting to return the batteries because the IR doesn't match what it was advertised to be. The fine print required might not be worth the headache?

Or, like all other 40C+ lipolys, the rating came from the marketing department rather than the engineering department......

yes I am familiar with the proper temp. to measure the IR at 72F and the reason behind it. Temp. goes up, IR goes down, Temp goes down, IR goes up and the 72deg F is consider the consensus of everyone because it become the norm as a "room temperature" per se . I mentioned my own room temp. because that was the room temp. I measured the IR last year. All my battery data will be posted at a proper thread when I am finished compiling them.

You IR reading needs to be at 72F to use the tool you link to.

Balance leads are appropriate for current that balance chargers use.

I won't post IR data for many reasons, one being the website it is sold on posts their battery IR readings yet still market their batteries at a Higher C then "maximum C" from the meter, checkout the big packs. This does not give me confidence on accuracy. (This is covered in numerous other threads and more relevant there.)


Deckbert:
I am with you 100%! I wish manufactures had a standard on C rating, it would make my purchasing lot easier and take out alot of the competition that sells cheap junk!

I also agree 100% with you on the taps, but I would add connectors as well! Every time E-Flite releases a new plane they stick a different connector somewhere. I bet I could out sell the E-Flite batteries at my stores months earlier if all the taps were the same.

On the registration, I agree as well. However it is is hard to mail you a box without your address!

I am as, if not more concerned, about C ratings. Just think about this. When you buy a battery you spend $20-$80 a time for some batteries. You want to make sure that what you get is what you were promised. When I buy batteries, we spend between $10,000-$20,000 per order! So I am very concerned about taps, C ratings, matched cells and more. I don't want to get ripped off either.

On the IR, I have posted in other forums that my concerns with this method and I will not be posting any data. No more comments from me on this one.

As 2dogrc has always done in the past, if you get a battery and are not happy with it for whatever reason, we will make it right. Just to let you know we don't get these calls very often, and I can't remember the last one. We have had Mad Dog batteries now for about 2 years and are very happy with the consumer and dealer response.
