On defining LiPo performance

It was six men of Indostan To learning much inclined, Who went to see the Elephant (Though all of them were blind), That each by observation Might satisfy his mind.

The First approached the Elephant, And happening to fall Against his broad and sturdy side, At once began to bawl: "God bless me! but the Elephant Is very like a wall!"

The Second, feeling of the tusk Cried, "Ho! what have we here, So very round and smooth and sharp? To me `tis mighty clear This wonder of an Elephant Is very like a spear!"

The Third approached the animal, And happening to take The squirming trunk within his hands, Thus boldly up he spake: "I see," quoth he, "the Elephant Is very like a snake!"

The Fourth reached out an eager hand, And felt about the knee: "What most this wondrous beast is like Is mighty plain," quoth he; "'Tis clear enough the Elephant Is very like a tree!"

The Fifth, who chanced to touch the ear, Said: "E'en the blindest man Can tell what this resembles most; Deny the fact who can, This marvel of an Elephant Is very like a fan!"

The Sixth no sooner had begun About the beast to grope, Than, seizing on the swinging tail That fell within his scope. "I see," quoth he, "the Elephant Is very like a rope!"

And so these men of Indostan Disputed loud and long, Each in his own opinion Exceeding stiff and strong, Though each was partly in the right, And all were in the wrong!

Moral: So oft in theologic wars, The disputants, I ween, Rail on in utter ignorance Of what each other mean, And prate about an Elephant Not one of them has seen!

Red,

That is a good one! It explains so much about people and R/C, expecially batteries. However, fuel is a close second.

It certainly *sounds* clever, but are you trying to say that people are `defining LiPo performance' without ever having seen a LiPo pack (or an elephant) or what?

Lets leave it at people are defining LiPo packs without ever testing them to any degree. I'm sure others get the drift of old poem. When a pack is "rated" at "20C continious" and then tested at 20C and the capacity after this is found to have been significantlycompromised after a few cyces, we are told by some vendors that 20C continuous discharge is not a realistic test. Duh????? CONTINUOUS - marked by uninterrupted extension in space, time, or sequence.

Reds just catching on to what the rest of us have discovered a year ago.. LIPO vendors, notably Charlie Wang of Thunderpower, Fred Marks of Kokam, and a couple of others, are engaged in a war of bullshit about aspects of LIPO performance that are completely irrelevant to the needs of most fliers.
