*don’t follow all the steps if you want to use it as a 12S.
Anyways I got one and I kinda want to get another to try it again without removing the Balance PCB like he does in the video.

What follows is me fixing my mistake of removing the PCB and having to find a new way fo attaching the balance leads of this Smart BMS
Decided to use the foil crimp scraps from trimming them to fit the Spim08hp cells as I have been looking for a use for them.
I had to get part of the tab up on this one side where they are harder to pull up, other side is simple.
hope it works good, taking it apart is a bitch.

Sweet. Are you keeping the whole thing as topmount?
Meaning the massive case

yeah, I need to add to the post how the whole top of the battery/case is actually a interesting water-cooling block. So I’m dying to put one super powerful ESC on there, and also hook up the motor to the cooling loop. That would be a first I’m pretty sure.
Battery, esc and motor all liquid cooled.
Real liquid cooling not crapor chambers lolz

just need to figure out what connector(s) I want to use but otherwise ready to run
This is to test it while I figure out how to use the plastic terminal thing, basically buy the ring terminals and get the bluetooth dongle wires to go through it.

Ok and I figured out how to bolt these down to a deck:
Flip it on it’s side and you get those bolt holes on the ends and side.
The bolts from the haggy mounts fit perfectly. Anyone know what size those are? I’m lazzy

Maybe I missed it but how are you using this? For esk8? Or something else?

top mount esk8 for now but it’s just a giant aluminum battery with a bluetooth bms for all your 19Ah aluminum battery with a bluetooth bms for <$200 shipped needs
Allow me to answer your question with pictures:
The Escs have to get mounted sideways

LOL…beast is right…omg.
Once you add on the cooling system it’s even more of a monster. With all the “free cooling” we can get when moving I’m wondering if it all ends up being worthwhile? I’m the esk8 noob though so I’m not familiar enough with the setups where using this pack would be a great fit.
Wow…I’d love to play with one or two of those things though. Just to see what can be done. Time and my wallet make that impossible though.
Thanks for the link!
my idea was that this is the perfect battery to stress test single motor + ESCs (more load in 1 spot)
Picking a watercooled motor is not too easy but I have these options.https://alienpowersystem.com/shop/brushless-motors/80mm/aps-83100sw-sensored-outrunner-bldc-motor-180kv-7kw-water-cooled/ or same for double the price lol
or this huge thing that might have the best $/performance

hellll yeah
see if you can crack open the DC to DC module and put ESCs inside, would need heat because the glue is pretty strong.

@Fosterqc notice this plate sitting under the battery?

you are funny, that’s the watercooling loop silly!
Take the DC converter thing on the “bottom” off and it should be obvious, there is a stir welded chamber for the liquid to pass though.
You can smell the coolant a little.

I’m not talking about the loop… there’s a plate above it with power going to it
that’s a peltier maybe
