Default Another way to mount your battery

It seems like most of the ORCRC guys that I run with either mount their battery to their front axle, or on the upper links of the front axle. The TXT axles are a little cramped for batteries, so I thought I would take a shot at mounting them to the upper links. I came up with kind of a hybrid solution—half is mounted to the upper links and the other half to the chassis. This allowed the battery to be as low as possible through the suspension cycle.


I used the Associated battery cups, available at Tower Hobbies for under $6.




I imagine someday soon that I will replace the battery straps with one piece of plastic that I could mount my receiver and ESC to.




The front of the mount consists of some angle aluminum, a rod end, and a scrap of aluminum that supports a ball above the upper link mounts on the axle. This setup allows the suspension to articulate while the battery stays level with the chassis:






The rear part of the mount consists of a new ¼" aluminum square chassis brace, and a sheet of plastic to keep the front and rear of the battery cups together. I cut out a section of the rear battery cup for the battery wires. Where the sheet of plastic mounts to the new square chassis brace, I made oval shaped holes so that it could slide back and forth when the suspension compresses. Lastly, I did not tighten the screws that hold the square chassis brace all the way to the chassis (don't forget the locktite). This allows the square rod to pivot with the battery mount setup.




You can see how the battery stays level with the chassis and moves up and down with the axle when articulating. Best of all, there is no more low-hanging battery for the upper links to bump into.



I crawled with the ORCRC gang last weekend at a location that I had not previously been to, so it is difficult to compare with previous performance. I have to imagine that it is an improvement in stability, but only more crawl time will tell.

From the last picture it looks like the upper link is still hitting the bottom of the battery tray limiting articulation.

Is that true?

Good eyes Badger, it does touch at full articulation but I think there is enough flex in the white styrene plastic that I used that it wouldn't limit anything. If it does turn out to be restrictive, I could always mount the ball end a little bit lower on the angle aluminum under the battery cup and that would raise everything enough to clear.

Looks Good! Nice Fab Work!

I wouldn't worry about losing much articulation, what you'll gain in stability is going to more than offset it. Besides to much articulation can get you in trouble.

That is similar to how my setup is in the way that when the suspension articulates at full it touches the bottom of my battery/tray not limiting any articulation. You can see from the pics I have notched out some of the stock battery tray to give me more clearance.

I have limited my articulation with my shock mouting positions.

I like your setup better because the front of the bettery weight is on the the axel not in the chassis.

I have my battery mounted a lot like that, not as pretty as yours though. Nice work!

Well I figured I would go "schlabinski" on my battery mount.

I really liked how low your battery is, but I wanted to do it with what I had so this is what I came up with. I also found a new location for my receiver pack.























Here is the suspension fully compressed. Every thing just tucks in nice and smooth.




Again, fully compressed and rx battery just moving with the suspension cycle not bothering a anyone.



And as always the originals are here:

I think I might have some Amish in me. 8O

Nice work, Badger. I like the way you made use the of the stock battery holder! Any impressions of it after having it in action?

Like I told rckjeep, my coarse at home is weak and my truck already went through it with ease, so I will know more when I can take it to a good location. I am doing a Comp this Saturday so that should give me a good idea.

It was only lowered about 1/2" so the difference might not be that noticable. I do know that my COG is lower though which is a good thing.

Well, I could not leave well enough alone. I tore everything out of the chassis and started from scratch again. 8O



I finished the new layout and like it. I went to go test drive it at 12:00 AM, but the only battery that will fit in my truck now was DEAD.

I am debating on wether I should post pics of it yet. I might wait till after the comp to see how poorly it does.

Heh, I want to do a major tear-down too, but I gotta finish my savage crawler first...

Good luck in the comp and I will be interested in reading your impressions afterwards.

Alright! I took a skid plate off pic of my new battery mount.
