lol ohh well its only money right?? :D

Yeah, I know, but I wanted to use the Quark. I'm only using the MM because I have no other choice. I have a mind to get it to work despite the fitment issues just to prove a point now. :p

Well thats what these conversions are about, you have to use your head to find a way to make things work, and if they dont, you comprimise. Are you sure there isnt any possible way of mounting it or not?

Im running the 80B in my buggy with no problems. The 80B is good for 200 amps for 10 seconds. Do you really see excerding that? Even in my Monster Trucks I dont see spikes that high. Certanly not for 10 seconds. I have a custom heat sink I made up for it to help keep it cool. Just my $0.02.

I don't see a problem having the controller next to the battery.

Are you concerned about heat from the battery? The battery likely will never get over 120* even on a 90* day... that's the hottest I have ever had a lipo get. My lipos generally don't get much above ambient temps (in summer)... maybe 10-20 deg.

I need to go back and check the layout you are using... I forget exactly what it is.

Just build a mount for esc, use standoffs and you can raise it over anything.

OK, without pics, this is hard to explain, but I can get it mounted. I just don't like the edges of the ESC so close to the battery (it's not the heat aspect). Call it being anal. :) If I raise it with standoffs or whatever, it interferes with mounting the shell. Plus, I want to leave a little room between the shell and the parts so that if I land on the lid, it won't bend/break anything. I know the real answer to that is to drive better :). Part of the problem here to is that I want this thing to look like it was designed for BL, not converted. So, no shortcuts or hackjobs. Another part of the problem is that I'm using Lipos in this and am a little gun-shy. You should see me handle them; it's like I'm carrying a bomb. I actually thought about making a metal enclosure for them! Yes, I'm paranoid. :)

A little earlier, I re-made the battery tray standoffs so they are now 1/8" further back. This should give me more room no matter which ESC I end up using for this. At any rate, the MM is on the way, so I'll have options. I have another conversion planned after this is done anyway...

Regardless of these "roadblocks", I still love these conversions. A little frustrating at times, but the end result is always worth it. Although, you wouldn't think I like doing this if you heard me downstairs swearing when something goes wrong. :)

I know what you mean about the lipo's being paranoid. I will be too, once I buy them, lol. But it is all part of it. :027:

Yeah... I keep my lipos buried in my underground bunker in the backyard... ok... not really. But I do have them in the garage. :)

I treated mine like nitroglycerine too... mine have all been bare cells... no prebuilt packs. Desk looks like I'm doing surgery when it's time to solder them up, lol...

Well, not so much anymore but still...

yeh lol same here, but idk... good to hear u found a new way to mount it..

and also what is wrong with the 80 b? its cheaper (which i like lol) would it get to hot or what?

Don't be too tempted to make a metal enclosure for Lipos, they come in soft polly pouches for safety reasons first not weight.

My dad was an electrical safety tester, responsible for giving out BS kite marks for the UK, one of the things came with AA size lithium cells, and in his effort to find dangers he put the 2 cells in a standard home nicad charger, and left them on an ovenight charge, he put the charger in a thin steel locker the type we have in schools and placed a screwdriver through the holes where the padlock would go.

On return in the morning he found the screw driver, stuck over 2 inches into a brick wall from where the door blew off and schrapnel from the bits of cell had blasted through the locker (creating more schrapnel) and bits of the metal cell cases and locker where all over the bunker, floor, ceiling, walls, the lot.

Its like gunpowder, you can put an ounce of powder on a plate and burn it in your hand but if you put it in a pipe and seal the ends, you have a bomb.

Theres videos of lipo fires and while they go up well and start fires, if your outside and one goes up 20ft away your prety safe, but stick one in a metal case and I wouldnt want to get within 100yds.

I think from memory those cells where 3.7v and 1200mah I cant imagine the destructive power of a 4s 8000 pack in a metal enclosure. Just dont Do it.

lol terrorists!! the po po shows up, we had a bunch of calls that ur lighting off bombs!! no no just my batteris for my toys:018:

Well, it wasn't going to be sealed, just mostly enclosed to help prevent punctures during a crash. I wonder what material the liposack is made of? It would be interesting to see if they could make battery wraps. That way, your cells are always in a sack. Of course they'll still vent if a problem occurs, but it would help mitigate the effects.

As to why I didn't go with the 80B; I wanted at least 100A minimum. Those current ratings listed are at 25 degrees C. But, we all know that running BL on a hot summer day can greatly exceed that and those FETs derate the current ratings. So, even though I won't be running at 100A, it'll be right where I want after derating.

I like confort level in my esc's too. On 5s, my 12020 runs a lot cooler than the 9920. My quark also runs cooler on 4s than 5s as well.

yeh i want the same feeling, but im asking lol
but can we get some updated pics?
