Machined AL battery trays - RC-Monster Forums

JThiessen · **Machined AL battery trays -** 05.27.2009, 08:29 AM

Hey, I was on RC-Tech a week ago, and found a guy that made billet battery trays. I pm'd him, asking about making one for my 8ight-T. He never responded, and somehow had his ad deleted. (could have at least responded to my question with a "no")

Does anyone know of another source for something like this?
Thanks

an aluminum tray would be quite heavy.... I would guess Mike could do it, as he has the equipment. Why do you what Aluminum? Mike will custom his plastic trays to any size (including thicker walls if you want).

Other then Mike, I would say find someone with a CNC or milling machine (try a local metal fabricator?) will probably end up being expensive....

Besides looks I don't see any advantages of alu battery trays, oh and it will act as a heatsink for you lipo's. But in a good geared system lipo's shouldn't get hot.

The "heatsink effect" will only work for part of your pack, umless you're running a 2s or 3s. Having one part of a pack cool and the other hot is not good.

As lipos tend to transmit heat reasonably well, I think a heatsink in there would not be a bad idea. Have some cooling fins milled on the sides (make them sharp too in case some a-hole tries to steal your lipo!) I was thinking of folding and welding some al sheet to make a tray, but kydex is soooooo much easier to work with.

Do you really thin the heatsink effect there is that significant? I know that every little bit helps, but is it worth the extra weight? I guess its worth the cool factor tho. I'd be interested in seeing these trays as well tho.

Wow, billet trays? That must create a lot of waste during machining unless he has some special process...

i wouldnt think so, i havent had a lipo get over 120* before

depending on the alloy the aluminum is made from it could be lighter than plastic

Your exactly correct on that. Lots of chips for the recycle bin...

I've done my own roll formed AL trays for my Revo, and even though they turned out decent, I want somthing that has a little more finished look to it.

I know any machinist or even Mike COULD make one - I just figured there would be someone out there making them already. The aluminum will be @ 3X as heavy as the Delrin/Plastic trays, but that only translates into a couple ounces.

Titanium trays with water channels milled in them for water cooling. Now that would be spifftacular! and erroneous all at the same time.

if its machined outa solid aluminum...it aint gonna be cheap. most likely in the 3 digits

This is true. Have them machine the 5 sides and get someone who can tig weld al to put it together. You could have the sides made with pocket cuts on both sides to reduce weight, and properly done wells always look cool to me! Still going to be 100 plus...

2 feet of L angled aluminum later....
Battery tray anyone?

Maybe put something on the bottom to protect it?

The tray on this truck is not Aluminum but almost everything else is. Eritex Inc. did all of the machining. I would send him a pm, he does lots of custom work and is reasonable on his pricing.

You can get C-Channel 6061 which would do the trick. Just pick the closest size you need, machine out the excess then add to end pieces the use screws to hold them. Weight could be just as light as delrin and some other plastics.

I bought some C-Channel aluminum about 2 years ago at my former employer which we used on machine we were prototyping at the time. It saved a lot of waste both in material and time.
