EVOLUTION - The 2 year idea.

In theory, 12s6p. i’ve seen it done.

In reality is a really tight fit and needs careful planning to make it work.

Thanks. Means a lot.

Im not sure multiple 6 month gaps in a project is “dedication” and the attention to detail is in everyone if you care enough.

12s6p of 21700?

Other footpad has finished printing after some printer issues (fuck 3d printers)

Time to trim all phase wires to length. get bullets on them. get them connected and heat shrunk.

Oh yes.

Still not sure on battery case orientation.

But im slowly coming round to @Venom121212’s way of thinking

With all your beautiful designs, I’m surprised you wouldn’t print a battery case to smoothly mount on top of the escs

Edit:
What CNC do you have? I’m quickly realizing i need this capability!

Coming back round to the idea of having the case inline with the deck.

Got the case modeled and then modified the ESC case cover to Have locating features for the pelicase.

Printed this and fitted it to the deck along with the MBS F5 Bindings

Put the pelicase back on to see how it fit.

yeah thinking that’s the winner.

looks very sleek and fits nicely between the bindings.

Then for fun i started trying other batteries i had in the garage.

The 2kWh lonestar pack is ridiculous. Might do for a test ride but not ideal.

Then i stumbled on some cell holders for another project.

This cant be unseen.
6x6 fits so nice on top.
A 12s3p P42A pack could be the perfect size pack racing.

Emtb build aside, this setup with a clear cover on top and a bottom mount battery would be unbelievably sexy for a street carver wanting maximum battery space underneath :drooling_face:

This though had crossed my mind a fair few times during the build.

What a tasty thread :drooling_face:. Thank you, kind sir!

@ ducktaperules Thank you very great thread!

This build with 4x Maytech 6374 and 4x Turnigy Panther 6S 6000mAh is 23.7 kg.

(Then I changed wheels to PHATLADS 10 inches).

How much weighs yours?

Still no real battery sorted but i just couldn’t restrain myself any longer, I had to take it out for a test ride.

Now i realise this is utterly ridiculous, But sometimes you gotta do what you gotta do.

So this was not a super long ride but i just wanted to check that everything was running right and that there was nothing wrong with drives or electronics. All seems good.

The ride ventured off into the forest for some sections and i did my best to keep things clean but eventually the inevitable happened and by the time we were done i had muddied the pristine grip tape :disappointed_relieved:

A nice table for your balls (bollocks?) to rest while you ride.

Again, i knew it was ridiculous to mount a 2kWh Lonestar pack in peli 1300 on top, but it was the only pack i had to hand at the time.

people ride EUC seated, why cant we? :rofl:

@DavidC
At the time i had been discussing weight with @poastoast as he was running a similar drive train but with a huge battery, so finally got around to weighing it.

15kg.

IMO this is pretty good for a 4WD

This is without a battery obviously, but my thought is that when racing you would add a small 12S lipo setup probably around 2KG total.

Additionally, I tried to keep things light at the time of buying parts, but things have moved on since that point 2 years ago. @3DServisas have a new revision of this hanger that’s lighter than the version i have. Otherwise switching to airs would save even more weight. Also switching from the stiff bigboi to a stiff bro deck would probably save another 1.4-1.6kg.

All in i reckon by switching deck and trucks it would be possible to get this down to ~13KG (+battery).

A race buildout with some small lipos could feasibly sit under 15kg

So this idea of a micro race pack had been bugging me.

it seems like such a good idea to have small swappable packs for racing. maybe you only need a few boardercross runs or 5 timed laps. Capacity isn’t a concern as long as you have enough power and 3P of high discharge cells should be more than enough to provide that for just a few laps. Or maybe the quick round town to the shops and back.

So i started drawing up a 12s3p Pack.

I really like the square format and i quickly realised that staggering the P groups made enough space to fit the BMS on the end.

Printed these out to get some in hand quickly.

Perfect Fit :ok_hand:

Welded up and it looks fantastic.

Unfortunately no pictures of the wiring, but it was very tidy :wink:

I hate to be that guy, but theres no fp rings on the positive ends, but your construction method makes it much less of an issue.

Keep posting! I’m loving this thread/build
