Is that battery current per side or total? If per side then I feel bad for the 3P pack you’re running at 100A

[Evwan]

Per side

I paid for 35 amps continuous I’mma use 35 amps continuous

qty motors (e.g. 1wd, 2wd, or 4wd)

Why do you neglect 3WD?

[Evwan]

Because no sane person unironically runs 3wd

a build thread for ChortL, an electric commuter skateboard My newest DIY-esk8 has been born. This is a commuter board for moving around town, grocery shopping, and is friendly to trains and shopping carts and hauling cargo. It is really heavy at 18kg (39 lbs) but it has the range to go almost anywhere. It has a handle on the nose. It has lights so I can be seen. It’s a sister board to the Blue One, the Green One, and the Red One. [20220709_003101] hand-built 100 cell Li-ion 42.0V battery …

For my bikeboard:

• 1wd
• 130Kv
• 12/140 #25 chain sprockets
• 485mm schwalbe wheels
• 20s7p BAK energy cells
• 135A motor/65A batttery, makerX HV200 ESC
• a few 100s miles ridden, relatively new build

It has about 400N of thrust in the low end, 4000W of power at the top end, and a 45mph redline. Curiously, it feels like the thrust increases somewhat up to 25mph, it’s not the sensorless transition so I’m not sure why it feels that way.

RACE BOARD

• 2wd
• 173 kv motors Reacher 6385 V4s
• 67:16 or 78:16 gearing depending on track
• 150mm SRB BRPs for outdoor, 165mm Meepo Cyclones indoor
• 16s5p Molicel p42a 32ah
• 80A battery per side
• 110A motor per side

Extra info:

• average speeds are usually around 30km/h when racing short track i think. I managed a 50km/h average the other day when i opened her up through the streets
• about 40-50Wh/km when racing
• SRB open gear drive on 3-link trucks
• front MBS binding
• Spintend 75V V2

Board is geared to 55-65km/h depending on track. Torque is decent but not mind blowing. I could do with greater acceleration as I get beat off the line still by lighter riders. I’m about 95kg rider weight. Overall i love this board but still want it faster. 3-links are definitely my favorite trucks for racing.

Offroad Board

• 2wd
• 173 kv motors Reacher 6385 V4s
• 5:1 Ratio with BN M1AT gear drives
• 8" stretched tyres on 65mm wide hubs
• 12s6p Molicel p42a 24ah
• 70A battery per side
• 110A motor per side

Extra info:

• average speeds are completely terrain dependant.
• MBS bindings
• Maker X D75 (but only cause testing. Dv6 pro to go back in soon)
• deck is Ramm offroad deck medium

Geared to 57km/h and plenty of torque. Not as much as the race board (mostly because of larger diameter tyres) but plenty for offroad. Only thing I’d change is run lipo instead to make it lighter for jumping. It’s a tad on the heavy side so i pull up very sore through hips and shins after jumping .

My commuter is pretty juicy too but not worth listing stats really.

Board was built for torque which it’s got plenty of. Lipos can dump some 630amps which i’ll never need.

SRB v5 Frankenbuild:

Gear Ratio - 3.25:1 Open Gear Drive
Wheel Dia - SRB v1 Race Slicks (150)
Batt - 20s4p P42a (Or was…)
Batt Current: 75 per side
Motor Current - 180 per side (sub 5 mile ride) 120a per side (over 5 mile ride)

Torque - Solid 8/10
Avg Speed - 37-40km/h

[Andy87]

My favorite setup so far:
Dual 6384 170kV
1:5 gearing on
8“ tires
Running good old escapes
at 12s
80A battery and
110A motor per side.

There is never enough torque (so 7/10), but it’s a good balance for me between top speed and torque.
Running 1:5.5 at the moment which does lack a bit of top speed with 170kV motors, so 1:5 is still my favorite.
Always a must have is
ramping time of 0.1s and adjusted throttle curve. As minimum with the Hoyt puck. Around 25% is about right for me.
I‘d like to compare that one to a HV build one day, but guess not in near future.

[Cyanoacrylate]

@MoeStooge or @fessyfoo i know ive already gotten all the tech spec from you, but id be interested to hear about your torque satisfaction; How would your rate the SRB v5’s (or similar setup’s) torque 1-10?

[ApproachCautiously]

• qty motors: 2
• motor kv: unknown
• gear ratio: 1:1 hub motors
• wheel diameter: 85mm
• battery configuration: 10s5p 18650 cells
• total current max: ~22 amps-30 amps (but probably much lower?)
• avg speed: 21 mph - 23 mph if both motors cooperate
• basic thane wheels
• deck: ultra flat with flex if you weigh a normal weigh, but no flex for me
• ling yi esc currently
• reverse “raked” truck in front on top of a surf adapter
• my right motor refuses to die

Also holy shit I was cutting it close with my hub motor last night. Any more use while the washer was broken in half and in it and the winding would have gotten cut through completely

I’ll post what my updated stats should be after switching out of the hub motors later

[tech.shit]

Here’s my main, she’s named “Lilith”

Power specs:

• 2WD
• 6384 170kv
• 12s
• 60A Battery 70A motor (x2)
• 2.78:1 spur gears
• Wheel diameter currently 150mm but changes to 105mm sometimes.
• Linear throttle.

Other specs:

• Split angle BN270 (45/15)
• Adjustable BN baseplates
• LY Switchblade 40
• eBoosted box
• LLT BMS
• Mini remote

Stats:

• Top speed: 61.4km/h
• Max uphill amps: 54A
• Max launch amps: 71A
• 0-60km/h in under 6 seconds (approx, haven’t clocked it yet)

Ugh… Range:
I’ve got a reliable 40km out of it so far. If I wasn’t shit at building a battery I could probably get over 50km out of it.

Self-Review:

• Torque 5/10. I’ve put stupid numbers in before and it felt so much better. I now realize I want 100 batt amps per side.
• Speed 8/10 I could stand it to be a bit lighter and quicker.
• Ride Feel 9/10 it would be perfect but I have a bolt that hits a motor and prevents the deepest of heelside carves.

4 motors

190kv

3.75 gearing ratio

6" wheels

12s5p P42a

25 batt amps per motor

50? Motor amps per motor

I figure 6/10 for acceleration and torque. Not slow by any means but not crazy either. Settings are conservative so I can put more power through it but I am happy where it’s at. Can power up hills no problem

I cruise around 20-25 with bursts Around 30mph. Not higher than that. Gets scary

4 TBESC’s. Belt drive. Flux deck. Tkp

[erroct]

My jalopy

• 2 motors
• 190kv motor kv
• 66:14 gear ratio
• 205mm wheel diameter
• 12s4p p42a battery config
  Per motor:
• 50a battery current max
• 60a motor current max

Torque: low, 3-4

• average cruising speed: 16mph, 25kmh
• torqueboards 6374 190kv
• Trampa 20mm open belt drive
• 8 in pnummies
• Earthwing NLS with the crush weld. its only 4 plys thick
• 2x torqueboards bldc esc
• Bad build do not replicate. It rides just fine from 0-25mph. On 12s with 190kv I seem to hit a wall where escs reach duty cycle around 27mph. Lame af, I want to go faster. Next set of upgrades will be new, lower kv motors (~170) and vescs that can handle higher erpm. My enclosure is a 3dp box that is tied onto the board with some dyneema - no additional hole drilled into the deck

@Cyanoacrylate

How would your rate the SRB v5’s (or similar setup’s) torque 1-10?

9.8 out of 10.

I’d say 10 out of 10. but…

@Andy87

There is never enough torque

actually i wouldn’t have said it when i first got on the board. it was basically more than i could handle. I think… think i could go a little harder now having had practice.

[Flyboy]

Out of curiosity, does the SRB setup ever have the torque drop off, like when you hit a battery current limit in VESC? Or is it full torque all the way to redline?

The mamba can only report battery current AFAIK, so it’s harder to figure out the low end torque as a benchmark
