You see that little parallel harness tapped into my main charge and balance leads?

Do not leave that hooked up when you hook up your 6S packs

It was a very short lived short that warmed up my balance plugs pretty good but it evaporated the mCPX harness.

I literally never use the word literally right.

So the little battery was plugged in when you plugged the big battery in?

No. Just the harness. But it has leads connected to the power.
When it's on 2S it's ok but on 6S the hot and ground are connected.

I think parallel charging is not dangerous,
altho I think them "squid" cables are a cluster f*ck ,and not the best solution imo, I prefer pregressive rc boards with built in fuses . anything can be dangerous in the hands of the wrong person.. so to say parallel charging is , is in fact a misleading statement imo,,, again there are safer ways to charge, but to each his own ,. and at the end of the day , as long as everyone has all there toes and fingers and there house isn't burnt down , I say fly on

going pro , one crash at a time

What? That an mCPX parallel harness might sneak into your set up?

When I hooked it up,my intention was to start a fire but I forgot it was there while waiting on the big supply.
So I burned up the leads before I got to burn up the lipo.

I'll make a new one

Going with this double fused paraboard.
Up to 40A per battery...should be future proof

It's pretty much saturated with oil and nitro. So I doubt it's fire proof.
Why do you ask? You think it might cause a fire? I would hate to have anything on that steel table that could be considered a fire hazard

I've heard of that and even suspected it once with my own lipos.
I changed boards from the cheaper one to the slightly less cheap one at Progressive.

I didn't charge enough after that to know if it was any different.

this is what I use for each battery while charging
since I only charge 2 at a time on my cheap turnigy 400W duo
and 400W was enough for my batteries used for my 500 they are 6S3000 50C
I charge at 4C

http://www.maxamps.com/LBA10-Balancer.htm

I highly recommend them for use when charging
