I am surprised those massive lipos fit in that enclosure. Did you do any modifications to get them to fit? Do you have space for them to puff? Afaik lipos fuff about 15% when put under heavy load.
Edit: So looks like they are only 15mm in height, that’s very good. How are you planning to charge them?
Right now I’m charging them individually. But I’m planning to integrate my charging system I have across all my boards. A power connector and a custom balance connector, connected to my 10s balance charger. I added some rubber gasket to raise the battery case a bit
Aren’t you worried about the flex of the board?
What’s to be worried about? It doesn’t flex that much either
The Li-po’s are placed horizontally and not vertically (depends on the way you look at them but I think you get my point) so they’ll be taking any slightest flex. I don’t know if there is any room for them to move when the deck flexes but to me it kinda looks a little worrying.
Hope I’m wrong cause it looks nice!!
Yeah, I thought about that, but after I added the rubber gasket, theres a tiny bit of room for the batteries to move. Also, the board does not flex enough to bend the individual cells. It would probably be a problem if I heatshrinked all the batteries together.

Then it’s perfect!
Do you prefer the look of the bamboo over the GTX?
Yes, I like the light, beachy look, especially since my Vanguard has black grip tape on it
I know the GTX has a cutout, but I really wanted this look

what’s the range like on this setup
I haven’t tried riding until empty yet, but my initial calculations give me around 22-24 km
Rewiring, and replacing 8AWG with 10AWG:

Alright, so I was on a fairly long ride and near the end of the ride, I tried accelerating rapidly and I felt at least one of the VESC’s cutting out. I checked the metr log, and the fault code was DRV8302. What causes this? Both VESC still works perfectly fine, and I’ll try accelerating rapidly again, when the board has recharged. I have also accelerated hard on full charge and there were no problems.
DRV fault at 18:08:44
What settings do you use for the vesc’s?
Maytech vesc? Had similar issue, went away when I changed to focboxes.
Change battery max to maybe 25A each vesc
Tried riding again today. There’s no problems when it is fully charged. I can hammer it as much as I want. Only when the battery get’s to around 30v (3,75v per cell) I get the error codes when accelerating hard. And only on one of the VESC’s. I’ll try changing the settings a bit, but it’s really weird, because I used these VESC’s on my other board with 63mm motors, and there I pulled a lot of amps compared to this board. Only difference is 50mm motors with sensors compared to 63mm without sensors, and the firmware. (ack 3.101 vs stock 2.18)
Settings are all stock except of the following:
Motor detection parameters
App setting parameters
Motor max: 47a
Motor min: -47a
Battery max: 40a
Battery min: -15a
Maybe it’s just getting a little worn out. I used the VESC for (probably a lot) more than 1000km
Lowered the battery max to 30a, no problems so far the most I have ever pulled on a board is 32a (per VESC) anyways…
Upgraded to FOCBOX’es, and now it runs in FOC!

What Vesc settings do you currently run thoose motors on?
The specs say max 47 motor amps, but I just upped that to 50a, so let’s see how that goes battery current max 40a
