True 150C rating

Eqauls a 100% state of discharge in 24 seconds and also implies 975 amps. flowing thru

genuine 12awg Deans Ultra wire

Have you posted a graph of a 150C (975amps) discharge anywhere?

Good luck testing that 150C rating. The 12 awg leads will have a higher resistance than would be required to achieve that kind of load.

• 45+ mph in most brushless setups (7.4 volts)
• 39 minutes average run time (6500mah capacity)
What power system setup gave these results? Results like these should have context so we can understand what is being demonstrated. Will there be smaller capacity high discharge versions available? Some high discharge packs in the 900mAh to 2200mAh range would be great.
Assuming it drops to about 7.4V from it's 8.3-8.4V full charged state while under a 975A load, the load resistance including wires would have to be under 0.00759 Ohms. I don't think 12g wires are normally rated for >7000W.

Let's just call it 1.21 gigawatts while we're at it.

I'd sure like to see a 24 second 975 amp discharge voltage graph...

We will have some graphs and videos shortly to demonstrate the raw power of these packs. I think you will be quite impressed. Our testing was very thorough.

We don't trust you, we trust 3rd party testers like Charles.

Are you saying you tested a 150C (975A) discharge?

Let's not be so harsh and just ask if they've used third party testers and would they consider it, I doubt the guy is a crook...

Last and in fact only cells I have tested from MaxAmps were their LiFePO4 2250s and I admit that they were very confusing to me. I could never figure out why they behaved as they did during charging, oh well.

Who needs 150C anyways????????

Ever see a serious RC Drag Race?

Scale 1/4 mile wheel spinning ,smoking must use a Gyro to keep it straight excitement.

I don't care about the 975 amps it might supply, but would like to see how the volts is holding up at say 100A or 150A over the full discharge to 80% of the cell capacity. That is what the value of high C ratings is to me. Five of the 7.4V pack would make a nice 10s pack for planes. If one cell is going bad, just replace 1 pack.

100A is only 15C for a pack with this many mAh 150A is not even 25C
