Be wary of fancy names and marketing like "extreme" and "sting". C ratings and capacities can be exaggerated and plain incorrect. Choose a reputable brand that stands behind their product and will be there if you have questions or problems.

And look for facts. Someone saying one is better that the other doesn't mean anything unless they can tell you why.
Your right there is no standard for C ratings with any battery company.
This is why I don't look at discharging C ratings.

I do all my own testing. I'm not sponsored by any battery company.

I use an icharger duo tested alot of battery packs with real time IR measurements.

Tested cheap packs to your most expensive packs.

I look for lower IR and longer higher voltage times.
When I do testing I have the room set at a controlled temperature.

I found that temperature effects IR.

Are Reedy batteries manufactured by a reputable LiPO battery manufacturer? This past winter, I purchased a brand new 1S Reedy LiPO pack from a reputable online retailer that came puffed/swelled out of the box.

My call into AE/Reedy customer support to remedy this situation was less than stellar. They offered a discount on a new pack. Fortunately, the reputable online retailer took care of the situation when they weren't obligated to do so.

By no "bad" batteries you knew I meant the difference between batteries. If you received a bad battery (defective), you should have been offered a new one assuming that you you either had the purchase receipt or the battery was returned (or photographed) and indeed new.

Reedy's 7000mAh 65C LiPo is designed for the serious racer who can take advantage of the extra power output and run time created by this battery.So is the best battery.

Whjat do you define as low IR numbers on a pack?

Do you copy things from the Manufacturers website and post it? Or have you tested multiple and come to this conclusion?

Single digit IR.

I recommend Sting packs. The batteries can be charged at a higher C rating as per manufacture without any ill effects.

Quick question, do you balance charge your Reedy packs every time? I have an ongoing debate with a fellow racer at my track who says that balance charging Reedy packs every time is bad for the packs. First time I've ever heard that claim.

I asked Paul Lemieux that same question and he said you don't need to balance every charge, just after every 2-3 runs balance charge your lipos.

You don't need to balance charge every time, but if you do there should be absolutely no ill-effects. Balancing ensures that each cell gets charged to it's capacity individually.

I always balance charge my batteries. Balance charging every time will not negatively affect the battery in any way. Neither will only doing it every few charges.

From what ive heard and researched is that there is only 3 places in the whole world that makes lipo batteries.....so who cares what make you by chances are it comes from the same manufacturing plant.....i have also heard that some places can sell there lipos cheapers then others because they own an assembly line in the lipo plant.....please correct me if im wrong but if only 3 places in the whole world make lipos....dont you think a lot of different brands are coming from the same plant and are the same battery just with a different sticker on it?

I think you'll find there are some Chinese companies doing some crappy 'copies'

There was a thread quite some time ago, where one of the guys on here also had to inspect the factories that made lipo's etc to check their quality control etc, (think it might have been for medical purposes) who told of some of the terrible factories that used to 'paint' the polymers onto the electrode sheets by hand instead of using the proper technique's.

Unless, during those 'few', something goes wrong with one of the cells.

With the blinky drivers starting to up the charge rates to wring a bit more out of their cells, it won't be long before we start seeing who's cells really can take the heat

Problem is that that is the kind of BS that a newbie might think is correct, so then he doesn't want to balance his cells at all.
