That thread is comical, poor Jason doesnt have a clue about... anything really.

I also find comical MA's 4 points about why C ratings are no good anymore; if a continuous current of ~100amps or so is enough to ruin the battery, wires, plugs and give you a 90second runtime, then how is some bollocks ~600amps+ surge rating with no info on duration any more useful? 600amps being pulled for any longer than a few milliseconds will destroy ones entire setup. It beggars belief they havent been taken to court before now for false advertising and encouraging dangerous usage of lipos... :neutral:

There is alot of this that's pretty comical really.

I've been working with Tech guys that service our 1000ah (not mah) 36 volt lead acid batteries where I work.

I've been asking lots of questions and doing my home work.

One question that I asked was:

What is the Maximum discharge for amperage for the 36 volt 1000ah battery?

We're talking about a battery that weighs about 2800 pounds and has huge leads.

The answer I got is:

750 amps. The cells themselves could probably go higher, but 750 amps is the upper limitation of the lead jumper bars. It is at this point where it will blow the jumper bars off the cells.

The jumper bars are huge. They are about the size of your average Lipo pack. The cells are connected with a pair of these on each side!

These large batteries power electric forklifts used in our freezer. Each forklift weighs right at 10,000 pounds.

There's ALOT of playing with numbers in the Lipo market. That's for sure. :yes:

Blimey...

It sounds pretty much the same as esc ratings- multiply theoritcal ratings together to acheive some rediculous spec that no-one will ever pull, but they'll set fire to their truck/ self trying to. Atleast some of us are clued up I guess, but we will always be labelled as haters for questioning a companies ratings & wisdom... :sarcastic:

"Frankly it would not be fair for me to pick and choose from your concerns, questions, and negative opinions.", as stated by Austin himself.

To me, this sounds like Nixon right before Watergate.

There will be a time to "Come clean".

It's really not that far away either.

If Jasons Specs and defense are as weak as they are for us lipo consumers I can't help but imagine how disapointed his poor wife must be ?
