This hobby is full of ridiculous markup, but you rarely see other brands getting bashed. A 35mL bottle of Xray silicone oil selling for $15, or a bag of 6 diff o-rings selling for $5, and there are many more examples. I can understand the frustration with all the markup on our hobby products, but MA is not the only one doing it.

You are completely correct.

However, its the fact that they left a bad taste in mouths for their products so they get scrutinized every time they do something.

About the markups, its normal. However, look across the board at buggy/truggy name brands. For the most part they are priced relatively close for relatively the same product. Now look at Maxamp's price for the same Turnigy pack, or even Hyperion. The prices aren't relatively close at all.

You put something from MA in your mouth? Not a good idea, you have no idea where it has been. And I really hope it was a lipo pack and not Jason's d.....

The difference is that you pay for marked up items like silicone oil, o-rings etc whatever it may be- and they have a very VERY low chance of causing catostrophic failure of your vehicle, i have never seen a car burned down due to under rated silicone oil or o-rings, I did however have a brand "p" pack go code red in my dx2.0 radio and have to promptly bury it in sand to later hear a series of low whistles as the cells vented. my silicone oil never went agro.

i dont mind paying overly high prices as long as the stuff works.. cant say thats always true for brand "p"

[JERRY2KONE]

Not to mention that when you purchase a set of "O" rings you get what you see in the add. When you purchase a LiPo pack you have no idea what you are getting until you hook it up and start using it. So your comparison is somewhat mute. The electronic business in general operates pretty much by its reputation because once they start having failures and the word gets out, no one wants to do business with them. Much like the rep that company "P" has now. Sure markup is pretty much a common practice, and 300% normal for the USA in general, but how much do you really think it costs for China to make these cells? I bet the true cost of LiPo cells is less than $1.00. So who is the real victom here?

Mike put MA packs in his trucks for display? They must have bribed him ALOT ( they can afford to )...

The XT8 had Hyperion in it!

Yeah, they were in the truck, but the truck wasn't running. They were there for display purposes only.

Actually, that last statement is speculation, so don't quote me on that.

Hey Guys,

Just wanted to post up quick about our new power supplies. Thanks you for your interest. I will try to keep this as short as possible. If you have any additional questions please feel free to ask and I will try to respond in a timely fashion.

Here are our two new power supplies:



http://www.maxamps.com/Power-Supply-12V.htm

Specs
* 100v-240v AC Input Voltage
* 12.15v DC Output Voltage
* 47A Continuous Output Current
* 575W Output
* 11" x 2.25" x 3.125" dimensions
* 3.25 lbs
* Short circuit and over-voltage protection
* Heavy duty metal cabinet



http://www.maxamps.com/Power-Supply-24V.htm

Specs
* 100v-240v AC Input Voltage
* 24.3v DC Output Voltage
* 47A Continuous Output Current
* 1150W Output
* 11" x 4.5" x 3.125" dimensions
* 6.5 lbs
* Short circuit and over-voltage protection
* Heavy duty metal cabinet

Both power supplies will charge at 47 amps all day long. A number of us have tested these and I know the guys at Big Squid RC have been using the power supplies with great results. Were talking about running two chargers each at 20 amps.

Regarding some of your comments:
One of the first things I wanted to do at maxamps.com was come out with an affordable power supply. I come from the computer industry and before that the electronics industry before I ever worked in RC. Day 1 at maxamps.com I started looking for power supply distributors and an affordable way for the general guy to be able to power his chargers and other devices at a rock solid price. I myself have built computer based power supplies and used them a number of times in the past for a number of uses.

We are not hiding that these are made from computer power supplies. We went that route because they are more affordable for average Joe. Right now it costs around $125- $160 for a good 20 amp power supply. Unfortunately this is only good for one high-end charger. There is a need now for more power with the latest Hyperion and FMA charges, among others that will follow suit shortly.

These power supplies are an incredible value for a quality product. MaxAmps.com are getting a really good quality power supply then we are modifying them ourselves at our shop. These supplies are wired correctly by electronic experts and are voltage checked for proper polarity and correct grounds.

We as a company cannot recommend to anyone doing these mods yourself. Modifying power supplies is dangerous and is something the average Joe should not be doing. If you guys mod them and they work that is fantastic. You are not the average Joe.

These power supplies are an affordable way to get the standard RC charging at a good rate with peace of mind that he just plugs in it and goes. No modifying. No worrying about shocking yourself. No worrying about ungrounded circuits.

A couple of you are posting some comments regarding legal issues and copying and things of that nature. There are a million computer supply mods out there and I have read a number of them. I believe this one actually exists on a number of sites as it's a popular server power supply. We did not steal anyone's idea and were not ripping off anyone's mod. We have the spec sheet from the manufacturer and we modify these power supplies to be both safe and easy to use.

Thanks and if you have any questions for me please let me know. Just understand that I am busy and trying to get done a lot this week. Wow that was a much longer post then I anticipated. Cheers

im glad you picked up where jason left off, i cant wait till next year when you guys invent brushless motors

[whitrzac]

what happens when the cases touch???


why are you not advertising the 100ish amps that they can put out?? it seems to fit with the other MA products....


WE, are not "average Joe's" even though an average joe could get a server PS to work, all you need is a pc jumper and wire to solder to the contacts....





what happens when one of these already USED power supplies fail???

The power supplies are brand new.

We will be offering a 1 year warranty on them that will be updated on the site shortly.

Thanks,

Brandon

Personally, floating one of the cases away from ground is NOT the right way to do it. It works, but there is a potential for something internally to go wrong (like a wire coming loose) and make the case float at whatever circuit it is touching. This is why everything with a metal case is grounded. Either that, or you'd have to wrap the internals in something non-conductive and then put that in the metal case, but what's the point in having two cases? Or, remove all the internals and put them in a completely different case with only the more negative supply ground referenced.

To do this "right" with minimal work, you'd decouple the supply output ground from the case altogether (technically, this only needs to be done on one supply), tie both cases together, ground both cases, and to make things more tidy, internally create jumpers of sorts to tie the mains inputs together (just so one power cord is needed).
