Sounds right, I was not the 1st to get a V1, but was the 1st to put it in a truck and do any real world testing with it, I received mine v1, 2 days after the
first one were received. have you opened the case yet?

My MM that failed on 5s was similar to yours. Power on and fried before I even got to pull trigger.

Thats fantastic, now I don't know if I should even run it for fear of frying my battery. When my V1 went up in smoke I only got lucky that the battery did not go too.

I guess I'll ebay it and stick to my nitro for another six months.

There is NO WAY the controller will "fry" your battery. Especially if you run decent LiPo cells. Unless ALL of the FETs shorted at the same time (completely impossible). Whatever shorted would not be able to handle the current and would vaporize instantly with the 150-200+ amps put through it that a decent LiPo can produce. And you know what? If the battery did puff, it probably wasn't rated correctly!

All of the failures I've read about thus far have been BEC/fan related which DEFINITELY would not hurt the battery AT ALL.

Larry, was it the fan wires shorting out? Did you open it up and check what might have casued it?

jayjay283 · 08.09.2008, 02:22 PM

Larry you plugged in 2x 3s 5000 mah Maxamps lipos and a Neu 1.5d ? Had you run this configuration with the MMM v2 before ?

lind5 · 08.09.2008, 02:39 PM

jayjay283 · 08.09.2008, 02:53 PM

ive ran my v2 for just over 3 hours combined time and no issues yet. Im trying to get Larry to say he screwed up so I feel better LOL but I know thats not the case. Ugh. Think I may take mine apart this evening and mod up the case and stuff like in BrianGs post.

What mods has BrianG done , tried looking for his post but couldn't find it .

After reading about a couple of issues with the fan wires on the v2, i'm thinking the fan wires might of cut through and shorted out on the board ?
