MaxAmps Race Edition Lipos

[Arct1k]

Because they wanted the "press" release before they went to the show - Could they have included the graphs with the release yes but they didn't.

Move on - As I've said repeatedly lets give the new guy a couple of weeks grace before gathering pitch forks and fire wood.

Isn't 90% of the above a rehash of earlier threads?

NO, He should have proof ALREADY. Not in a few weeks...

Well, you know, its fun to use the search feature sometimes- type 'maxamps graph' in and have a dig.

Once upon a time MA sold 4000mah cells that they themselves rated as '12C constant and 16C burst (conservatively)'. How things change.

I also like this thread: http://www.rccrawler.com/forum/showthread.php?t=117095

And this: http://www.nitrokillers.com/showthread.php?t=1527

Quick mathes- 119.8amps / 4.2amps ( 4200mah ) = 28.5C. Take a look at the cell voltage and you'll see its down below 3.2v after only ~10% of the discharge cycle. Thats the ~27c cell rated for 35c that I love to remind Austin about so very frequently.

I'll shutup now, but I will say this as a final comment: better have some bloody good graphes to show us after iHobby is over...

From looking at those pictures of the garage MA makes their lipos in it does not look like a very big operation. And it look like only one guy works there, all the other work stations are empty. How do the few people that work there keep up with sales and warranty work?

[BrianG]

You're forgetting that the guy taking the pics probably is working there too...

One man can do a lot of work when he is good at it.

Actually there are a lot of one man shows around here. In our hobby alone I can name a couple. Robin at UE has been a one man show for over a year now. Dan is a one man show for Kershaw Designs, and MonsterMike I believe started out as a one man show. Of course Mike has had a lot of help from forum members and local supporters in his area. The problem with one man shows happens when things are successful and the business grows a lot faster than first thought. Then again some business owners want to keep things small so the business does not take over their lives. Not sure what the issues are with company "P", but something must be working. The question is for how long?

[josh9mille]

Im wondering how long it takes to put together a 3s pack. That guy must be on meth to keep up with orders. just remember he must assemble enough packs to pay for all the advertising in mags, forums, race events etc, plus enough to pay the mortgage on his garage, house etc. plus enough to pay for the new marketing managers salary and his travels and room and board when he goes to shows like ihobby etc...the list goes on and on im sure. Hmmmm.........maybe i just explained the reason why "company p" lipos cost soo much! lol. But seriously how could 1, 2, 3 or even 5 or 6 people make enough packs to cover all those expenses?

It's sad to say but they do sell a shit load of packs....

[E-Revonut]

When you buy the cells for a couple bucks each and sell a pack for $200+ it doesn't take to many to make the profits you need. A dozen packs a day could make you over $1000

[lincpimp]

Do you guys really think that MA assemble the packs...? Maybe (and I stress maybe) they put the main leads on and the balancer taps. Maybe. I took alot of them apart, and the early examples had the al tabs press crimped together. Later models with the copper (paper thin and press crimped to the same al tabs and sorta hidden under the foil) might have been soldered together.

I am guessing they order the packs as 2s, 3s,4s, etc and add the wires, taps and shrink. I can put those items on very fast, maybe 5mins a pack. Not to say I have assembled many packs, only a few hundred. And out of those maybe 50 were put together as individual cells. Given their layout and some 8hr days I could churn out some packs. Especially if you had one person per station and did it assembly line style. Pre cut the shrink, tin all of the balancer wires and main leads and then have at it. I can see at least 100 packs an hour come out if you had 3-4 people.

Hey Guys,

Here is a graph for you. I just got back from iHobby so there will be plenty of more of these and some videos to follow. Please be patient with me as I am very busy this week. Also, I saw Mike Cronin at iHobby and I gave him some Race Edition batteries to use as he see fits. I believe he said he was going to hook up an Eagletree system and do some real world testing on the track. Here is a discharge graph at 50 continious amps. Most 1/10 scale vehicles pull nowhere near 50 amps continious as you already know. Video of the testing will be posted shortly. Chat soon :) Brandon

Hmmm.........What is that? About a 7C or 8C discharge for this pack?

I was hoping for something a bit more aggressive that would show your competitive nature.......with other "premium" packs.

To be any sort of indication of a 150C rating, 50 amp discharge is nothing really.

Is this how you plan to show the performance of a pack capable of a 975 amp discharge?

50 amps is just a little over 1/20th of it's rating.

[slimthelineman]

Around 9c? Don't think it really matters what kind of current the cars pull we just want to know where this arbitrary 150c rating comes from.
