Your pics have been driving me crazy. I couldn’t figure out how you got your cells lower than the divider. It took many views to realize you had lined the edges of the pack with foam. I’m still thinking about using braid. How much of a sacrifice would I give up? Just flexibility?

Even with braid I feel like you’re still gonna need a gasket 
And i hear too many bad things about using braid for flex joints. Although I do have my doubts about how much the 44 actually flexes. Especially yours.
I don’t wanna swing you one way or the other because I know that plenty of people are running braid in similar configs but if it were mine, i wouldn’t use braid.
For me the sacrifice would be never really being sure if the braid was holding up.

Thanks, bro. I’ve got a 1/2" piece of rubber for the deck and piece of 3/8" for the enclosure coming. I plan to cut/shape/melt them into submission. Should be fucked up as a football bat.

Frakkin’ brilliant.
It’s the little touches like this, and that great wedge, that make for a really nice pack.

Oof. Minor design flaw…didn’t take into account the order of the balance wires in relation to the battery layout. Lucky there is enough room in the wire channel for some kung fu.

Yes I was kinda guessing at first but it worked out good for the DIY kit slide-on version, that seems reliable enough with all the glue.
damn I forgot to say that I was imagining I would print sideways the long way up, did not even remember once I saw this pic.
like this the tall print with a small footprint might be a bad idea on fast prints.
oly overhang is where you would never see.
Awesome, love the improvements I can take those into my new versions and stuff.

Can’t get the bluetooth module to connect to my phone 
just keep getting the message “connect pre close” and then this
It connects fine to the other battery in here. Abyone had a similar issue?

I don’t trust those yumcha smart BMS. I have had one kill one of my 10S packs drained it to 18v. Was running in bypass with a loop key.

Not only do I imagine Albert is on many watchlists and no fly lists, he’s not going anywhere with that ankle monitor. (You can see it in earlier photos if you have a keen eye.)

They’ve been flawless for me until this one…
But i figured out the problem! The two white data cables were crossed! Swapped the cable and all good!

Real life is busy. Not heaps of time for my esk8 fantasy world. But we’re on a 5 day lockdown again here in Melbourne, so I’m damn sure gonna make some use of a few days off work.
This has been on the books since early December. Feels good to finally make some progress.
Single stack 21700 enclosure for the flux. The commission brief says that I gotta use the existing pre-drilled insert holes
It’s a bitch because it makes it suuuuper tight to fit in 10 cells across. Buck has no draft, except in the segments, and the radius where the buck meets the deck is gonna need to be super tight.
Perfect project for me to finally learn infusion, because i’m gonna fuckin need it.

Minimal work done on the enclosure today, i glued the buck down to the deck and that was about it.
Nearly finished welding my minipeen 12s4p p42a for the choochoo build.
I’m gonna use all the parts that I won from BOTY for this build, and i’m pretty sure the build name needs to be BOTY-licious

To vac infuse this enclosure, i’m gonna need a big ass flange. Built up around the deck with timber and covered with corflute, need to fill the gaps with wax before moving on to the next step…

Was all ready to pour some silicone, had the vac set up and ordered extra silicone cos i didnt think i would have enough…
Had 1kg, ordered another 5.
Mixed up my first batch and was surprised how thick it was. I thought i was gonna be able to pour this shit. Whacked it in the vac chamber and it just turned to mousse 
It went from nothing to pretty much exploding in a split second 
I let the pressure out, cleaned it quickly and put it back in, away from the valve. Left it under vacuum for like 5 min, and it just stayed looking like mousse.
Relieved the vacuum and took it out, it settled a bit but was still moussy.
It had been like 10 mins since mixing and it was already well and truly kicked.
Within 30mins it looked like this.
I tried again thinking that if i heated the silicone before mixing in catalyst, i might be able to get it runnier. It didnt work.
For science i mixed in the catalyst anyway. It began to kick pretty much immediately.
FAIL
I’m gonna need some runnier silicone. This shit should be ok for the bulk layers i need to do, as long as I can use it quick enough before it kicks.
400grams of silicone have gone to science, but I shall press on.

So after some more sciencing and a frantic 2hr conversation with my old pal Russ, i discovered what my problem was…
First, the sciencing.
Russ was adamant that I had the right shit and basically said, just fucking send it Al. So i did but after we swapped some videos of the viscosity of our splooges, we started to have doubts.
It was at this time that a dude on a local chat said "al, if the shit is meant to be liquid and its not liquid, then its probably been stored incorrectly or was old stock to begin with’
Now, to be fair, i have had this little 1litre pot of silicone for at least 6 months… so I opened up the 5litre tub I just got, and it is beautiful and runny, just like it should be 
So, the night wasn’t productive as such, but I did learn lessons. My half arsed splooging and general fuckery taught me that
- my buck works and the silicone releases beautifully from it
- the silicone is absolutely going to need reinforcement to keep the shape of the ribs and to hold it together while demolding
- i am going to use a fuck ton of silicone to make this mold
- i didn’t charge enough money for this job
But onwards and upwards, tomorrow is a new day for me to fuck some more shit up
