Mamba Max above 3S LiPo
 

Hello
I'm hearing some problems with MM running above 3S.
Having polar opinions from all over, including Castle Creations (their claim was 14 cells (above 4S) no problem), and not having an ESC which can have such a failure mode. I am curious if anyone would like to offer its MM controller with such problem, so I can investigate and offer solution.[/COLOR]

I'd love to help, but I've got the old gen2 MM. I've got hope of picking up another MM in a few weeks for another project, and if no ones beat me to it, I'll get mine shipped via GriffenRU :) I'll keep you posted.

I just got a brand new. They scrapped my old one and just replaced it for free. I don't know how it fairs above 3S though...I'll let you know when I find out.

I actually just bought a new MM ESC (2 days ago) for my RC10GT :smile:. So should I just plug in my 4s pack and see if it works? Unfortunately I do not have any 7 cell packs to make 14 cells.... I also wanted to run 2s through it for my GT, and was planning to keep the internal BEC. Could I still try 4s for a couple minutes just to see if it works? Or does the external BEC really have to be wired in?

Make sure you use the external BEC on 4S. I don't see what the problem should be with 4S as long as you use the external BEC, that's what I do with mine. How do you tell which version you have? Mine's fairly new and I'd like to check it out.

unscrew the two allens on either side of the heat sink and look at the bottom board when you take it out. The gen1 and gen2 both have 18 fets (little back squares) and the gen3 only has 15 fets. There may be other ways to tell but this is what I know.

Thanks, I'll do that tomorrow.

Mine didn't work on 4s. DickyT has it now.

I thought yours didn't work on 14 cells, but worked with 4s except for all the cogging it had with the neu.

didnt someoen say if you put too many volts through it, it will just read an "overload volt" warning or something like that?

No problems on 4s here, both gen 1 and brand new from the factory versions (gen 3?).

John, when was yours made? I don't know if mine is ok on 4S yet, but I hope it will be. I do know it was made in November 07 based on the sticker under the board.

The newer ESC was made two production runs ago, so first of october/late september maybe?

Hey JRH. I just ordered a Mamba max. I assume it will be a new one. The new ones have less fets? Are they of better quality or do the new ESC's have lower voltage tolerances? I am going to find out about the mods Griffinru does when I get home from school. I would like the ability to run 5 or 6s lipos on it. Well be home around 3.30, darn school

No replies darn. Hey Griffin RU. I just ordered a new mamba max saturday. If you still need to see it I might send it if you are able to make it better. Maybe like mods for cooler running and higher volts and such? Maybe like stick two together with a bec?
Let me know.
