Voltage cutoff with 2x 2S.

Would that explain why on my first long bash session with my Savage flux, it all of a sudden got VERY slow and then actually stopped and wouldn't go anymore unless I let it sit for a second and if I blipped the throttle, it would go for a few feet then stop again?

I was running SMC 6000mAh 28C 2S.

2.7v is probably ok for medium to small loads like cellphones and laptops, but our stuff pulls a LOT of current and the 3v/cell+ is just extra insurance. One other thing; I noticed that cells stay in balance far better if the LVC is set to 3.1v/cell or more. Lower and one/some cells can be substantially lower.

Whether you choose 3, 3.1, or 2.7, I usually follow this rule of thumb: Set the LVC point such that when you remove a depleted pack from the load for ~10 minutes, the voltage should rebound to at least 3.5v/cell.

Thanks Brian, I know I can count on your opinion about these things. 3.2 volts it will be for me. 3.1 volts only if I need to squeeze as much run time as I can but mostly 3.2 v per cell.

Brian, I have to ask. WTF is up with the no fan avatar?

Oh no you didn't! Your in for it now.

lol, I think CC is just trying to guard against people pushing their product too far. I ran my MMMv1 fanless until it blew, and not from high temps; it was just sitting there and then poof!

Computers are a different story. Generally, you computers are not running in dusty/dirty conditions bouncing all over the place. And if yours does, you have more problems than just fans.

But hey, if you like fans, then more power to ya! I just think they have a time and place, and R/C is not one of those...

12 fans I've got 1 on my storage drives, 2 on the cooler for my raptor, 1 in my PSU, 1 in the rear of my case (don't really need it with the way my CPU cooler is setup), 1 for my CPU, and 1 for my GPU. That's half as many fans including HDD cooling. Your computer must sound like a Jet

I agree with Brian's position on fans. You shouldn't NEED them, but they are a nice addition to make your system run even cooler.

Ah ok, so I didn't hurt my Lipo's then, they were just really drained mAH wise but the voltage was still safe?

I posted my first bash session with my Flux today here: http://www.rc-monster.com/forum/showthread.php?t=20716 Was fun as hell, I was just worried cause I didnt' know how a "voltage cutoff" for a Lipo worked or how my truck would react to it.

Yep, the "Blur" ESC is a Mamba Monster with different stickers on it. If we meet up soon to bash I'll give it to you then, if not I can always drop it in the mail. I'll just send it to you as it's a spare that I don't need, even though you are a Grizz I'm getting PMs, don't worry.

I try not to run mine very long once the voltage cut-off kicks in. I don't think you damaged your lipos but I primarily run Maxamps packs, and I treat them like they're made of glass so they don't fail on me.

I saw your vid and all the pics (the pics were excellent!), some friends and I will be out there sometime for a bash. There's a place in Rocker, MT that has some great bashing and also some rock crawling that we may be going to tomorrow.

"Mini Death Valley" also has a dirt/rock piles the guys take their rock crawlers on. We also set up a dirt/obstacle course that the guys use to race their Baja's.

Basically, we have it all in one big ass place. To see how big, check out my vid here
