LaCroix Prototipo | APS 8072S | 12s6p 30Q | ESCape

Video and pictures


  • LaCroix deck - Very highly recommended. I was having real trouble actually buying a nice-looking 12s4p enclosure for an Urban Carver but LaCroix provides an all-in-one solution. Feels very nice, very comfortable, doesn’t feel too wide.

  • APS 8072S - I didn’t have the budget for a dual drive, and I wanted a higher efficiency build, so I went with a single motor. Considering an 8072S is about the same price as a 6374 I thought I could use the extra power, especially since I am not looking at adding a second motor. So far I have had fairly good experiences with it. I was having some resonance issues at 65% but it is much quieter when the belt is on and I am standing on it. I certainly don’t feel like it doesn’t have enough power, although max braking current doesn’t seem very strong - this is probably due to ESC configuration and not the motor. Although warned about, I have not felt any turning to either side when accelerating or braking due to being a single motor.

  • 72 Samsung 30Qs - The board can fit 72, so I bought 72. Arranged in a 12s6p configuration. Definitely makes the board a bit on the heavier side.

  • ESCape - Works as expected, but JST-PH connectors are more difficult to find contacts, terminal blocks and crimping tools for. I would’ve preferred to seen the more common JST-XH, although I accept size constraints may have factored in.

  • Urban Carver trucks - Purchased with an Urban Carver deck and not replaced when switching to the LaCroix deck, maybe thinking about swapping for the wider MTB hangers (16 inches).

  • 6.5" Trampa pneumatics - Smaller than recommended for the board but I haven’t encountered any clearance issues. Feels very firm at 40PSI but can be lowered on rougher terrain and reportedly safe up to 75PSI for smoother.

Nice build! What did you use to weld the batteries?

Car battery with a solenoid attached to a relay attached to an Arduino giving 50ms pulses.




Building a spot welder similar to that but without an Arduino, I am going to be so triggered if it doesn’t work out

Could you share the code you used with the arduino? I have built the same setup with a momentary switch but have a spare arduino nano lying around that could be put to use.

Cool! I have also build a car battery spot welder but without the audrino. Glad to see it works.

How did you get 12s6p batteries to fit in the Lacroix enclosure?

I put another 2 6p packs in the space mean for ESCs, only leaving enough room for my BMS and forcing me to mount my ESC externally.

I’m actually not super sure I’d recommend it :confused:

How did you externally mount the esc? Do you have pictures?

I’m sorry, I can’t seem to find any pictures and its currently disassembled, but I just stuck it using double sided tape to the top side of the rear mounting hardware. My current plan is to make it an 11s6p and keep everything internal

I made an 3D printed case for the ESCapes. In case you have a dual heat sink that would work also on any other deck, not only on trampa.

I can’t find the original sketch, it was something like this:

void setup() {
     pinMode(13, OUTPUT);
     digitalWrite(13, HIGH);
     digitalWrite(13, LOW);

void loop() {


Pressing the reset button can then be used to control the welder.

That looks awesome! I don’t suppose you could send me the STL?

I can do later. The thing is that the battery cables made to come out for a top mount battery. It could be changed to the side but for this I need a pc and I have only access to a pc next week. The case is mounted via the inner spring holes of the trampa truck. If you don’t have this holes, some wood threads in your deck would do s great Job too. If you still interested just sent me your mail via pm :wink:

Ahh okay, I wouldn’t want you to go to any trouble, thanks anyway though :slight_smile:

It’s not a big thing. I can change the design next week or sent you the step files and you can modify it to your needs
