had to come back with this thread and see if i needed the low voltage cutoff for a 2s lipo pack on the mgm80?
thanks

The MGM controllers have an adjustable cutoff that can be programmed on the controller itself. No need for a seperate device with these controllers!

you know, that would prolly be great if mine would program at all. I am utterly dis-satisfied with my results on the mgm, i guess i must be too dumb to progam it (will explain in a second), what do you have that will handle like a lehner 5300, is programable via computer (or simple like novak), and doesnt need a reciever pack???
now with the mgm80 programming....
i do just what it says to get into programming mode:
turn on radio hold FT, then turn on controller
after `10 secs, it beep 3x, then go FB for 1 beep, then neutral and 1 beep

when i go back to neutral, i get 2 beeps, so i dont know where i am or what it is doing.
normally not such a big deal, it runs, but with issues with it braking and backing up on its own and then i now have the 2s pack i want to run....i need some major help in figuring out what is going on, or what i can replace this pos with.
i will appreciate any help from anyone on this issue....also if anyone could use a SLIGHTLY used mgm80 and 6s motor....

When is a good time(early evenings hopefully) to call you? PM me your number and a time range and I will give a call to help you through the programming. I struggled with it for a while myself!

The backing up on itself is really a nuetral position error. If you could possibly reprogram it or adjust the trims on your radio, it should all straighten out. Mine runs flawlessly.

The Mtroniks genesis controllers meet your requirements but nowhere in the US stocks them so you have to order directly from Mtroniks in England.

My MGM 12012 controllers also beep 2 times when going back to neutral. I just figured it was a typo in the manual and decided to go through with the programming anyway. Every change I've tried in the programming seems to work.
Essentially, what I do is turn it on holding full throttle on the radio, wait for it to beep, push full brake, wait for it to beep, put the radio in neutral, wait for it to beep. I've pretty much started to ignore how many times it's beeping, as long as it IS beeping during programming. Once I'm into the programming mode, I press full brake once to set car mode, then full throttle to save the setting and move to the next.
The last test I have to perform with the controller will hopefully happen tonight. I will use my ICE charger to discharge my 2s lipo to about 6.3 volts, then attach it to the MGM and run it to see if it cuts out at 6 while programmed for 2s.

Lastly, when I was programming an MGM 12012 for my Jato, I had a problem with needing the throttle on the radio to be in reverse due to the brake servo. I couldn't program the radio in reverse, and when I programmed it in normal, it would not work once I put it in reverse. I ended up trying other servos I had laying around until I found one that worked correctly in normal on my radio. Make sure you're not programming in normal and switching to reverse for actual operation.

let me know how everything works out with the ICE, i have an ice also and once i get my mgm setup for lipo, i will be using it to charge a 2s pack also.

Batfish - I have an even better idea. You know how the ICE can do motor run-in? Plug the ICE output wires into the MGM's input wires. Go to the motor run-in option on the charger. Set it for about 7v. Turn the MGM controller on, and set the throttle trim so that there is low forward throttle. The motor will spin, because the ICE is supplying it with power. Now, on the ICE, you can adjust the voltage while the motor is spinning. Take it down to 6v, and see what happens. Bring the voltage lower until the MGM cuts out, and the motor stops spinning. This is an excellent test, and is more precise, and you don't want to risk your Lipo.

That's actually a pretty good idea and I may try it. I do, however, have an E-Flite power meter, which I put in-line with the battery and ESC, so i can monitor voltage live. It takes readings 3 times per second, so I'm sure I'll be okay monitoring it that way. I just planned on using the ICE to discharge the lipo at 10A and set the cutoff voltage at 3.2v per cell so it will stop and let me move the pack to the vehicle (with the meter) for final bench testing.
I've already tested the voltage cutoff using my nimh packs, and it performed as it was supposed to. Now it's time to prove it with the lipo packs directly.

Sleepy32 - I use my ICE to charge my FMA/Kokam 3s 3200 packs and it works perfectly. For the BalancePro packs, I use FMA's specific BalancePro charger.

Test completed. Here's what I did and what I got for results.

1 - Discharged 2s2p 6400 pack using ICE charger set for 10A discharge and 3.2v/cell cutoff. Due to the higher amps, the ICE actually cutoff properly, but the pack went back up to 6.8ish.
2 - Restarted discharge at 1A. ICE cutoff at 6.46v.
3 - Plugged the pack into MGM. MGM beeped an error; it was the error code that indicated incorrect cell count. I appears that the MGM needs a minimum voltage to register the lipos correctly.
4 - Plugged the pack into the BalancePro charger and charged at 7.5A for about 5 minutes.
5 - Plugged the pack back into the MGM. MGM started up correctly. Meter read 7.46 volts on the pack.
6 - Moved the throttle trim forward on my radio until it was moving the wheels and drawing from the pack at a steady rate of 2.5A.
7 - Set up a 12v CPU fan to keep things cool while I let them run for what turned out to be around 20 minutes. The 8-cell SPT nimh pack is powering the fan.
8 - MGM cut off the lipo pack at exactly 6.2 volts when running at a constant 2.5A. Assumedly it will cutoff the same at higher amp draws, but the pack voltage will rise slightly more after the higher amp load is cut.
Here's a pic of the point of cutoff:

I'm going to add another post that shows step-by-step exactly what I did with my radio to set up the MGM for 2s lipo.

All told, I'm happy with the MGM lipo cutoff. :)

well i dropped the kokam 2s pack in my t4 just to see if i got the controller set right.....well the pack (straight from the package) had so much punch in it, i figured i might as well throw the gps to it. well with the pack in that condition...it still pushed the truck to a little over 41mph and i thought that was pretty damn good considering my 8 cell pack only pushes the truck to about 46 while carrying the gps
