I used super glue as well and it's fine so far, id recommend using a decent brand like scotch or gorilla glue though since it might hold upto high temps better than generic stuff

Why can't you just put a box under the downtube? You could probably do around 120-130 cells that way without it being too unwieldy It will look low profile and still look like a regular bike, hardly any welded frames look good except for that guy fpvlee who did the mondraker summum and he's already ...

SN-01BM crimper, ive done probably close to 100 jst-sm's and haven't had a failure

How long does the bluetooth module last on these things? Mine seems to have killed itself after about 6 months

That board isn't neccessary either, can just run 3 power wires and 3 ground wires and the signal wires as normal from each hall

Here is another of my unwanted remarks 8) This level of capacity loss at 5C discharge rate should be clasiffied as excellent result. But the major problem is, that Samsung 30Q shows almost identical capacity loss under 3C and even under 1C continuous discharge rate. So at 3C continuous discharge ra...

How does that happen? Doesn't the enamel on the windings prevent that? It will, if there is no damage to it. But if the metal of the laminations is in direct contact with the windings, at the sharp edge of the outer lamination, and the windings are tensioned against that edge, vibration will cut th...

Another problem that at least their "3k" (450x) motors have is some of them end up with shorts of one (or more) phase windings to the stator laminations, at the outer lamination of the stack where the wire changes to/from the end turns. (I have one like this that I was able to fix by lifting up the...

Good thread so far, been said many times though can you test 30q? Not everyone wants to build a 30kg battery out of 29e's

There is multiple shorts in that arrangement

To be honest I would just add a bluetooth bms and use that for balancing and logging, and i would wire it in based on this diagram like so

Well that sucks. I got a similar response from them too

Dear Sir,

Unfortunately we don't ship to Australia anymore because of the changes in regulations concerning shipping of lithium batteries.
We apologize for the inconvenience!

Kind regards / Met vriendelijke groeten,

You want a sub 2.25kg hub motor that is capable of 45a continuous? Id like one also

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?
