Yeah fechter is right its too much dead zone, you need to adjust the input voltages which almost no-one does Even cheap throttles work really well when the input voltages are adjusted properly You can do it with resistor on the ground line of the throttle (beginning dead zone) and resistor on the po...

Do you guys have test report for your 35h 1500w hub?

I have questions also since i couldn't find much information when it came to building a pack with multiple layers either

Do you need to have a ground from each seperate layer going to the bms or just the ground that is from under the +1?

100a at 52v is just awful, you only use that amount of amps once you already maxed the voltage around 20-22s

Use the grin simulator and plug in some different voltages and kv's and find where you will reach peak efficiency at the speed you prefer

Test results: LG HG2: charge-discharge rate at 100% DoD (4.2V charge with 100mA cut-off, discharge to 2.5V, rest time 10min) 0.5C-1C test: 94% after 50cycles, 92% after 100 cycles, 80% of initial capacity after 1000 cycles, 0.5C-3C test: 90% after 50cycles, 88% after 100 cycles, 79% of initial capa...

My battery is only 18s5p 30q so id probably run out of battery before I could overheat it anyway

I bet you could do it in under a minute if you put 7 kW to it, but you'd probably destroy the battery too.

I bet it would last longer than a minute

FWIW I've got a motor similar to the leaf 1000w and it's taking 2.6-3kw and I can barely even heat it up. It's got every mod though, 24" wheel, ferrofluid, inside side covers painted black etc

Looking for a good condition used CA2 or CA3 in Australia or overseas and will ship, let me know what u have

Do you guys know if the KT-LCD8 display's will work on non KT controllers? Obviously i won't have any programming features but i should still be able to get voltage and speed readout assuming one of the wires from the display is for hall's

I made the same thread a while ago. I ended up adding a 150 ohm resistor on the ground of my throttle and it moved the idle point from 0.83v to 1.17v (wheel moves at 1.23v)

Removed almost all the dead zone and there's just a tiny bit left for safety

It's got an offroad mode? Or is it stuck on 50kmh?

It's happening alot now, my late 2017 1000w conhismotor hub surprisingly came in 30mm and 0.35mm lams

The website only offers US shipping, is there international shipping?

Because the edge of the nickel strip can be very sharp and easily pierce through the wrap and existing insulator, that's why you add that extra layer of protection

Sick build, how does the rear suspension on that compare to the mongoose?

Use Anderson's, they're basically the only choice if you don't want to solder

Your phase wires are 1.5m long and you have all these spade terminals connecting it together? Wtf is going on

Type machinist into Google maps and start calling?

I think like you said you might struggle to find someone who will do small jobs but you might get lucky

I had someone machine my dropout, brake mount, and torque arm for 50 bucks which was a pretty sick deal now that I think about it

I'd recommend against it. Use stainless cable ties or 3d print brackets, do whatever you can to avoid it

If you do drill make sure you drill the smallest holes possible and deburr them to relieve stress

Yeah im happy with it, the 1500w leaf would be a way better choice motor wise but im gonna use this one until it melts :lol: Nice! Correct me if I'm wrong, but what I understand you to be saying is basically the battery is too small, and the motor and controller are overkill. Basically I just need ...

Cheapo ebay 1000w DD, 12 fet em3ev infineon, 18s5p samsung 30q

Sounds like the 30Q are good cells. Are you happy with that setup ?

You're looking at >12v of sag trying to pull 150a out of 5p vtc6, it's not gonna happen, you're massively over-estimating that tiny pack There's chargers all over aliexpress for 50 bucks that can do 20s Thanks. I'll have a look for the chargers. What motor/controller/pack do you run ? Cheapo ebay 1...

It's gonna be barely any faster though, the leaf and that 3k mxus will both be able to handle the burst current from that 5p battery you're planning Those cells are rated to 30A. I figured 150A would be enough. What would you recommend ? They're not rated to 30a? And why are you splitting such a sm...

Weird build, everything is way heavy and overkill and expensive for 60kmh Look at getting leaf 1500w, 24" bicycle rims and 18 fet infineon I can see where you're coming from. And I totally agree with you, if the only criteria was to reach 60km/h. Originally I was thinking more along the lines of th...
