looks at price* I need new undiees...


maxamps rateing= 60c
real rating = 10-20c

*cough* *choke* *splutter*

$250 for a 4s pack?? It better hold 3.7v/cell at 60C to be worth that price!

whitrzac: I've said it once, and I'll say it again; I'm sure that 60C spec is real (no sarcasm), but notice they do not say what the voltage will be at 60C?

I supose...

60c surge, so i take that rating as a 30c constant and 60c burst.


translate that and i expect 20c 50c......i got my math right?

[BL_RV0]

I'd say 15c/25c...

[nitrostarter]

I say let them do their advertising and have the UNEDUCATED buy those over-rated packs....

[ClodMaxx]

even if it were 60c, why the 12 guage wire? can't they splurge the extra 5 cents a pack and upgrade to at least 10? i mean, if it really is 60c, lol.

well they do say 4660watts surge @ 315 amps(=3.7v/cell)

and on their site they explain:

Using a data logger and an actual RC motor and speed control, we test the “surge watts” by applying a load to the pack(not an individual cell) and confirming that it will maintain well over 3.2V per cell during this load. By using this method, we are confident that your MaxAmps pack will deliver the rated “surge watt” load without hitting the low voltage cutoff or damaging your pack.

[BL_RV0]

So... $250 for a 4s pack that MIGHT hold 3.2v/cell...

[redshift]

Jeez they couldn't even make a flashy new label?

I'll believe their claims when I see a 3S version start a 1:1 V8.... should do it according to their equipment right?

[BrianG]

Hmm, still, I'll believe it when I see it. Testing of my own MA packs leads me to believe otherwise (granted, they are older-generation cells). Maybe they listened to the masses and/or got tired of warranty claims and actually have cells that performed as advertised now? Still think the price tag is a bit hefty...

Definitely a bit hefty. I would consider trying their stuff if the price wasn't outrageous...

[BrianG]

It would behoove them to send a sample pack to a respected third party for verification. Some people simply have a bad taste in their mouth from past experiences and it would lend a bit of credibility to have someone substantiate their claims.

60C is just MA omitting the continuous C rating and using the surge, they are playing with the noobs here. They aren't lying or anything (although they might be), they just aren't stating the C. C rating with I'm sure is something like 30C or lower in reality.

The surge watts is BS though, that is based on the fact that a lipo cell is 3.7v/cell Nominal, they think they can do a simple calculation and multiply the nominal voltage by their so called 60C and get that number. It sickens me.
