What is this BS Castle is feeding this customer?

[lutach]

With 6S, I was able to run 20+ min. with 2200mAh cells and my average AMPs were 10A (9.92A to be exact). The spikes were between 70-128A. The Monster Max for being a fresh design is not showing any sign of a design flaw. All I think is happening are a few Switching BEC that have gone bad. You can't blame Castle for that as Castle don't make the components. I sell electronic components and some times my clients try to blame me for faulty components, but it's not my fualt.

Well isn't it 3900 x .02 = 78A
MAH x .0C = A

EDIT: Also, it should be worded differently in that the higher output batteries are needed for use with the CC MOTORS, not due to the ESC!

Actually insufficient batteries CAN damage an ESC from ripple current. That's why we want you gents using batteries that are more than sufficient for your system. :)

Couldn't that be prevented by installing a diode on the battery leads (unless the MMM uses regen' braking)??? Seems like something that should be done if there is the slightest chance of it happening.

Yes, thanks Austin! 3 pages of speculation was 2 pages too many IMO.

[BrianG]

Yeah, that did sound bad didn't it? Oh well.

I was planning on going to the track anyway. Any idea what classes are planned to run and what time we're starting? I'd like to run the buggy if possible. Or maybe the Revo or CRT.5. Don't want to run the Jato because it's too tempermental for me, especially since I'd be in the mod truck class with the other pros.

I'd like to see the MMM, but don't want to take the chance to smoke it. Besides, all my setups use ESC mounts that are too specialized to switch between ESCs that quickly.

[What's_nitro?]

It may have been said before but I didn't feel like reading every post. There is no way that an under-powered battery can kill an ESC! The LVC would hit and it would shut down. I can't figure out where CC is trying to go with this one... Are they trying to protect their earnings by telling people to buy better quality batteries so that the system will perform as advertised? It's up to the end-user anyways to make sure his/her components are matched properly. If something fails, like a battery getting too hot, then it's their fault for not matching the battery to the job. I don't see why CC is concerned... Further more, why would MA be saying "don't buy our stuff"? They should say "only buy our 6000 packs or bigger" or something like that and tell people why!

You may not want to read every post, but you should read post #47 on this page from MA. About CC, we still don't know the full story until Patrick or another CC rep states their side.

[BrianG]

So there we go. Responses from both Castle and MaxAmps. Rumor squashed...

[lutach]

I know who he is and this is where he lost me: http://www.rcuniverse.com/forum/m_60..._1/key_/tm.htm post # 13. He was using a 300A Schulze controller before Schulze had a 300A controller and if you keep going you will see when I asked him in post # 51 for a picture. After that he was gone . Let's see what he'll say in rctech http://www.rctech.net/forum/showthre...58327&page=212 i'm post # 6347.

A lot of people are still running 3-4S and that's where a higher AMP rated cell will have to be used. When you step to 6S I don't think you would see a lot of high AMP. I get 80A or so spikes with my MBX5T geared for around 45mph. Now my BPP is a heavy truck and I have seen close to 170A spikes, but when I don't want to go fast, I usually see 90A spikes.

So, any new MMM failures been heard of today?

Mine failed yesterday. The mailman just picked it up to bring it back to Castle anout 30 mins ago.

Same as the others? Just lights out, or did you let the genie out of the bottle?

No, lol, it was the same as the others. I let off the throttle and coasted for a few feet and when I went to accelerate again there was nothing. BEC showed 1.09 volts and no communication with the Castle Link.
