Default C-rating nonsense and outright lies, with uniform tests

About the marketing 'optimism', the nonsense and the outright C-rating lies, with standardized/uniform tests:

It's just money right? You can trust the average company to provide a decent product... right?

Online yesterday.

... a lot of the time, C stands for crap ...
Have you ever wondered how a 100C battery gets away with an XT60 connector that is only rated for 60A? If you use lipo batteries in your RC planes, helis or drones then you need to watch this video and learn why the C rating of your batteries might not be what you think it is. There's also some other lipo info in this video that hopefully everyone will find interesting and of some value.

Ron,

Ive known this for 10+ years nothing really has changed even the Graphenes by design just current limit and run cooler cause Volts are easier to transport than is amps but watts is always the same. I have my own formula and shop for lipos with a scale and never been dissapointed.

10 grams of battery will net 25 watts of power for 3 1/2 minutes.

Given that 750 watts is 1 HP its pretty easy to convert liquid fuel to Epowa by looking at BHP. This formula works on everthing from 1S micros to 14s+ helis and planks. The one thing that sticks in my head is a Tan striped Thunderpower 3s 1320 rated at 13c-15c weighed 90g and could put out 250 watts, OH my isnt that close to my formula? Todays 3s 1300mah packs are a porky 120g-130g with ridiculous C rating there really just rebadged larger packs putting out nothing but a C ratings from begining of the race IMO.

The only thing I have seen moving my flight timer needle and granted its still 45 sec or less is the new High Voltage cells for the same apples to apples gram weight of matching counterpart.

Shop with a scale and youll never be dissapointed, shop by labels and youll always be dissapointed..................

That's a very handy rule of thumb.

The ongoing tests revealed a few blatant lies.
