@Cuprani nice build for the first time! Btw I live in Rotterdam centrum :smiley:

nice strap design - where did you get those strap bridges and the plant tray? looks like a really nice and simple solution plus it actually looks good.

I love the strap design mate well done :+1::+1:

Thanks all!

@Maxid, I’ve updated my start post, so you can find the links there.

I love your enclosure idea. I will look into finding a plant tray also. Right now I am using a IKEA kitchen cabinet tray.

Here some pics of the internal layout.

Al battery related components are fixed on the enclosure.

I wired my BMS, but still waiting for the 50,4V charger and connector to mount.

I want to keep the board as stealthy as possible.

I drove about 30 kilometers last weekend. I’m really happy with the Riptide Chubby WFB bushings. Hit about 50 km/h (31 mph) and it kept really steady. It feels really good when carving, but tight turns are a little harder.

Nice first build! Looks clean and stealthy!

I now drive in foc mode at about 80% of it’s capabilities. I can run at 100% but then the vesc gets over 70°C (158°F). So to save my vesc I changed motor power from 80A to 65A.

Made a test video with my 360° cam to check the topspeed at 80% of it’s power. Also connected my phone with the board to log during the video. It’s really crappy sound and quality.

Video starts at 3min50sec for topspeed run.

Also available in 360° (open in youtube app or chrome for 3D)

Just in case someone from Germany wants to mimic this: The German word for this type of strap bridge is “Lakeikrampe” - I had to search forever to find this. Can be bought cheaply on ebay: http://www.ebay.de/itm/10-Lakeikrampen-Kunststoff-25mm-schwarz-/262740282869?hash=item3d2c8a8df5:g:LlMAAOSwImRYPWXf

Hi Cuprani,

the plant tray link doesn’t seem to be working. very nice, clean and stealthy build!

16

How well is it performing in the rain? Mine shutted down.

@AreaKruzer, Thanks! I see the item is removed. You can find it by searching on: “Plant Sill Tray Black 55cm Saucer Trough Garden” from seller “forestfox_trading” [Click]

@Mark, I don’t drive in the rain, but I do drive on wet roads after the rain. There is never water in the enclosure, even when driving through puddles.

Thanks for the link! You’ve been a great help!

thats quite nice. Could you share how your working with the bms? I wanna do the same

@Mark I have to admit I got back on my BMS setup.

I discharged my lipo’s to much. I had my vesc set at 38,4V (3,2V per cell). My first cell was discharged to 3,0V while the others were mostly around 3,3V. 3.0V is seriously bad for the remnant life of the lipo.

Now I’ve got my cut off set at 42V, but because of the difference in voltage I decided to play on safe and use the BMS for discharging as well.

If you do not want to use the BMS for discharging you simply only connect the “B” (balance) from the BMS to the minus of the battery, and mount the minus of the charge port to “P” on the BMS. The plus on the charge port you connect directly to the plus of the battery pack. Also you have to connect all balance wires.

This is the cleanest way to mount an enclosure IMO. Take no offense when I copy this design :slight_smile:

22

Just realising, you’re plant tray actually looks like the mastercho enclosure. But 10 times cheaper :smiley:

Jeez, have a little respect, @MasterCho does much better work than a plant tray :slight_smile:
