Any ideas guys on a shop I can find me a 200a breaker for my build please? Already have a 125a but my battery build should be good for 200a burst so want all I can get from it. Any help would be good help😁 Try out the 125a breaker first. You will probably find it will be ok. If you were drawing a c...

The specialized turbo levo is the must have emtb at the moment for sure. The new 2019 model has had a big overhaul and redesign from previous versions, so it maybe worth paying a little extra and getting this model rather than the 2018. Just buy the cheapest version and upgrade later if ever needed ...

I have already contacted the support but no news!

It reminds me of the ignition wire you get on Lyen/infineon controllers.

is that a circuit breaker and a shunt? in my shunt i use the negative not the positive and than connect the positive iginition ( 7 in case is kelly) also to the shunt

Maybe it is? I thought it was a circuit breaker with a pre-charge resistor built in.

Hello to you, I wanted to follow this pattern but unfortunately the result is not conclusive. Can you help me using my schema? I would be very grateful to you! http://image.noelshack.com/fichiers/2018/52/4/1545937128-wiring.png Have you tried measuring voltage across the various parts of your circu...

Well done guys. The lower the noise - the more the customer.., simples! Less noise on chain drive systems is the holy grail in RnD.

Thanks for the updates

Qulbix Q76R looks much better than Sur-Ron :D :D Looks like it costs nearly twice as much as a Sur-Ron (177%), has a smaller capacity battery, and a hub motor. Not to mention the Sur-Ron's forged frame looks infinitely more professional. I doubt that. It was self built. Quilbix frames are excellent...

The cells need to be warm to get the best out of them. I am pretty sure that internal resistance will be a lot higher in cold temp. I found that my samsung 30Q cells give much less capacity when cold.

Also if the cells are new, i would cycle rhem a few rimes before testing

You have chosen well. Great bike. Solid parts. Excellent set-up.

Glad to hear the Q76 frame has held up well! I looked at the Vortex too, but it just looks too much like a motocross bike to be able to ride it without any hassle here I think. Performance should be similar though, and I'm hoping the Q140MD will feel natural to pedal on rather than relying 100% on ...

Its very weird why the video footage is edited at 3.14. You see a charging cable at 3.13 and then there's a little blip and it's gone. Why would they want to edit out the fact it was charging?

The lower the turn count the higher the rpm. The motor will spin more times per volt

Give the guy a chance, Haah! The solder has barely had time to cool on the very first board. Ha! TAKE MY MONEY NOW!!! OK...no not really...this controller needs some vetting yet. But I am quite interested!!! My hope is it can do 150 volts. I'm willing to sacrifice some of those crazy 500 phase amps...

Some lovely torque. How much sag you getting on your pack. Just wondering what it takes to get to 60kph

no one? .... considering people always looking for cheap batteries and deals on here i thought there would be a little more action... these don't look bad https://www.aliexpress.com/item/100-Original-LiitoKala-Lii-35A-3-7V-3500mAh-NCR18650GA-10A-Discharging-Rechargeable-Batteries-For-Sanyo/32823361...

I have few new cells from nkon here. Some after few cycles. Samsug 25R shows 11,5 miliohms AC and 18 miliohms DC at 4,08 V. Sanyo GA shows 20,4 (24 new) miliohms AC and 35 miliohms DC at 4,08 V. Temperature during measurement cca 25 C Sanyo GA cells in my one year old battery 10s5p are about 38 mil...

If I remember correctly, it takes a few cycles for a brand new cell to achieve it's best IR (and capacity), so that might be why you could see a used cell with lower IR than a new cell. Have to agree. I was first dissapointed when building a 20s 27ah samsung 30Q pack. First 3 cycles gave higher sag...

#219 chain should be plenty strong enough

Adam has ordered in some 14t sprockets for the lmx motor. I will be trying this soon with a 100t rear sprocket from eBay. This will give a slightly lower gearing ratio of approx 7.2:1 instead of the original 7.8:1 With the idea of reducing some noise from the original 12t front sprocket. The lmx161...

Hi all, while I was replacing the hall effect sensors I damaged few magnets inside the stator. couldn't find an alternative! I believe they about 2.2 mm thick * 13.9mm wide *28mm long. Got N50 30mm x 10mm x 2mm from aliexpress that didn't work it's very weak compared with original one. any suggesti...

Are you sure your replacement magnets have their fields aligned the same as your old magnets?

This is possible but unlikely as they tend to repel each other when Sliding into place.

Hi Doit,
I have some spare magnets (out of an scrap hub)
size approx 27 x 13.9 x 2.8mm
Have a re measure and I'll send you some if it helps.

Jonno

Just make sure they're in a large enough box not to get magnetized to the inside of a post office truck

I have no international shipping experience whatsoever. How much do you think it would cost to have one sent from the middle of the US to you?
I'm in zip code 63116

Not much, If sent by normal airmail in a padded jiffy envelope. Probably only 10 or 15usd
