Weipu SF12 or SF8 has seen some use recently

Offtopic, given your name i assume you’re in germany?

[Spanajohn]

Yes, polarity was correct. I was using a 5.5x2.5 dc jack and had positive on the inside prong and negative on the outside casing. Thinking of changing that too with a new one. But as @glyphiks said I will not use a fuse.
The worst thing is that I can’t charge (and therefore ride) until I receive my new charger…!
Any suggestions for round and short charge ports with a cap? Because I don’t have unlimited space (depth-wise).

@Spanajohn

what’s ur hole size?

[Spanajohn]

Diameter 16mm but I’m ok with up to 20mm I think. Depth cannot be more than 18mm because of the baseplate.

GX16-2P should fit right in, the port only need 13.1mm of depth

Example of a 3P version, but they are all the same

This thread is an absolute monster but for the most up to date battery building practices you can bring any questions here:

The battery builders club

Was getting ahead of myself with pre-welding some packs that i didn’t realize how i was wiring it together/the orientation of the battery… Im doing a 18s6 in a flux v1 using this video as a reference. [IMG_9099 (1).PNG] [IMG_9100 (1).PNG] took a while to make a drawing because of the timelapse. This is what i got from the stills i was able to capture. [IMG_9101 (1)] Also, only 1 wire for the series connection? idk how I didn’t realize I would need 10 gauge. Or can i just double up on 12gu…

[glyphiks]

Oof, i can’t recommend gx as a charge port due to the male pins. Weipu SF12 is my reco for charge ports

@glyphiks

due to the male pins

there are inverted version of the gx connector…iirc

How much power is required to easily wheelie up the front end from a stop?

[frame]

@Tony_Stark will be able to answer that

Where’d you get that printed insert? And is that a switchblade?

[ApproachCautiously]

I still don’t know how people are making their boards do wheelies and burn outs. so if anyone knows the answer add that too please

[glyphiks]

Yes

I think that might be a remix of mine actually

A lot of motor amps and a front binding
Mine didn’t start wheelieng till I got to 165 motor amps on 12S in BLDC mode (FOC seems to feel slower for the same amps in my experience)

[ZachTetra]

I’ve gotten wheelies at 12s 60A per motor, but it’s geared for torque and I’m light

[Spanajohn]

No, it’s a hummie.

Depends if you have a tail, and also depends where your center of weight is relative to the back wheels, and also depends if you have a front binding.

A board with a [functional] tail will wheelie with no power and no bindings.

A board with no binding and the back wheels extended 50cm behind the foot platform probably won’t ever have enough traction or power to wheelie.
