So basically I went from around 45A Battery and 85A Motor per VESC with the old setting to 65A Battery (combined - Dual with the correct multiply option now) and 115A.

So Like I mentioned the torque is a lot weaker with the current setting - so I might try to find a sweet spot that is a little higher than my current setting but still safer than my old setting

I got the lights and the switch that comes with it is huge haha. Is it just a basic switch? Think I could swap it out with something smaller so I could build it into the enclosure?

Sure every switch will do.
When turning the switch off and on fast you will change through the modes.

Normal mode
Low power mode
strobe mode

hey guys.

So I decided to upgrade from my 12S4P to a 12S6P.
This is the result:

Some more details:

  • Upgraded from my 12S4P to 12S6p (30Q) because I wanted a little more total height climb capabilities
  • Removed my Flipsky Anti Spark Switch because the MOSFETs blew (the classic Drain to Gate short
  • Decided to make a Loop Key with a socket
  • Changed the Box and overall design a bit with an all new Round Voltmeter
  • Changed the charging socket to a high current socket
  • Used a special foam on the bottom of the board with springed screws to have a solid mount but not limit the boards flex
  • Had to prime and spray paint the box because it usually comes in grey

Pretty stoked with the result - was well worth the work

I probably will try a new loop key design that is less high and has a little more modern shape to it

Stunning work dude! Hope the paint on the box stays okay it looks pretty finee. And will you upload the loop key part on thingiverse?

Its that one… I just sanded and primed it and then painted it with black matt spray.

Nice. I’ll be doing the same with this enclosure for a 12s7p. It’s a bit smaller than yours by the looks of things.

@brown5tick

You sure the 12S7P will fit inside ? or do you keep the BMS etc somewhere else ?

Well, 99% sure, yeah. I’m working with @pjotr47 and going off this as a reference:

That’s a Peli 1150, which has slightly smaller internal dimensions than the Bud-25338.

Got any photos/details on this? Are you using threaded inserts in the deck or bolting straight through?

I didn’t make any photos but its basically just something like this:
These springs are in between the case and the top of the screw

And the Foam is a double sided adhesive foam type just like that one (between the case and board):

Love this. My box is 200 x 200 x 130 tall and I’m hoping to fit a 12s6p. We’ll see what happens :man_shrugging:

Might need to stand the unity up or get a custom L shaped pack made lol

The problem is that I made my battery pack for another case so I could if I wanted make a completely new one and easily fit a 12S7P inside my case - however I just added 2P’s to my 12S4P to make it a 12S6P and the dimension was not optimized for my new case.

However I was able to add a big heat sink for my BMS and had enough room to run all the cables inside.

So I am quite happy with the current box. Could have ended much worse :slight_smile:

Loopkey turned out great. Will upload it to thingiverse later

Looks great! You think you could shell the loop key face and make the loop key wire go through the top? Might shave down the profile a bit.

Regardless, a very clean solution.
