MaxAmps Race Edition Lipos - 10.15.2010, 12:46 AM

I can't believe I'm the first to post about these.

Anyways, MA has new packs out which lay claim to a "True 150C" discharge rating. Sounds great. They are using 6500mAH cells... Raise your hand if you think they can actually support a 975A discharge. ...

Nobody?

So suddenly they're back to C ratings again. Or will there be a 14430 surge-watt rating on the 4S pack? Even if the cells CAN put out the juice, they aren't going to do it through 12AWG wires.

In all seriousness, when I see that 4S pack start a V8 engine, I'll believe the 150C rating.

I think you pretty much summed it up! lol. However someone should really try to start a car with one! My guess is that it would puff and/or melt off battery leads.

Maybe they will put up a video of it jumpstarting the Deathstar...

I have 2 alkaline D cells that will kick it's ass.

wow.... well it must be right cause they used the word TRUE in the rating without any other info to back it up.... like a graph. i would also like to see a 12awg wire carry 900+ amps even for a fraction of a second. most 600amp industrial panels use 750mcm or larger in multiple runs, and not at 7.4volts either. saddest part is people actually are buying this crap, or they wouldnt advertise it and still be in business. someone need to call these guys out along with the other manufactures and stop the false advertising.

Here is the link for their new race ready battery. They are claiming that it is simply the best Lipo battery in the world.

The claims have no limit, just like the C ratings.

It all has to do with having a fancy sticker printer.

They shore do print some fancy labels.

Assembled fresh in the USA really means "We put the sticker on it!"

$100 says my hyperion g3 vx series 6500 2s will stomp that pack. (while being a premium pack yet costing about $50 less)

Hey Guys,

Thank you for the interest in our new packs. I will have some new videos and graphs to you shortly. I believe you will be impressed. This truly is a solid product and I believe you will be extremely happy with the performance. Rootar, If you will be at ihobby I will take you up on that bet and we can test the packs together.

Maxamps has chosen to play the marketing game with the argument about C ratings for so long, it's just old.

Now, since sales are obviously sagging in this economy, (along with the fact that people are catching on.........karma you know?), Maxamps has tried several attention tricks.

First design on your "stackable" assemble-a-pack idea was a lawsuit in the making. I'm glad to see you finally got your head on, and came up with a better idea to eliminate dead shorting and the potential firebomb.

Now, It's obvious you've went back to the "True C rating" instead of the "Burst Rating", but came up with your own numbers once again.

True product competition isn't just about sticking a number on a pack. The proof is in the pudding.

But come on! 150C? That's just a lie.

If you can provide me proof, that your pack can hold even 3.0 volts per cell for 30 seconds at a 975 amp discharge, I'll buy!

IF Maxamps DID come up with such energy density and discharge capability, you would have such huge Government contracts, you would probably forget about the RC market altogether.

That's not how things are gonna go there, in the garage though, is it?

True that. If it was possible to get 150c discharge from Lipos we would have had our roads full of 1:1 cars with Lipos in them already. This just sounds silly now. How stupid do you guys think we are? Almost a 1,000 amps out of an R/C Lipo, REALLY? Are you kidding... Come on show some graphs or a video comparison that will make all of us believers. We really do want to, but up to now you guys have lied and given false advertsing to the point that no one trusts you guys any longer. So wheres the BEEF!

While skeptical, I'll hold off commenting until I see the full ratings along with 3rd party test verification. I personally would like to see a graph of voltage, current, and temperature vs time at various continuous and burst currents. High C rating is only beneficial if it can be drawn for more than 1ms without causing a fire.
