Anyone having trouble with the current measurements in the app? My shunt was labeled 1.16 mohm, but I'm reading peak battery current of 146A. When I'm at 55% charge or less and I hit the throttle, the battery bms low voltage cutoff triggers. I do have a 16s7p 30q pack, but I don't think those numbe...

Yep, I ran into the same problem. I've gone with a 40t chain ring and I would say it is probably the largest that will fit in the frame.

Combine that with a (14-17-20T) 3 Speed Freewheel and it's ok to pedal up to 40kph.

A front chain guide will probably make your commute a lot more enjoyable.

This is mine.

Thanks for the info. Any update on your build?

Is there an update on this build?

Vector's website claim the seatpost is 30.6mm, but you have a 31.6mm. Did you have trouble fitting it?

A different pc program can also be downloaded from the above link. Please let me know if it works for you as your programs don't work for me.

Just an update on my problem with bt not connecting. The seller finally got in contact with me sent sent me a link to download the android app which is different to the xiaoxiang app. http://smart-bms.com/M/Support/Download/ This app does read the bms details and cell voltages however it continually...

"Minew"! Sounds like your hitting on a different device, my app lists a few local Bluetooth devices when I start it up. It's definitely the BMS. It disappears when I disconnect the power. Thanks for the suggestions, . I'll keep you updated when the seller finally gets back to me. I hate C...

I was thinking about your BT connectivity situation... 1. In android settings is a place to check for available BT connections. In there the BMS should be listed as "xiaoxiang BMS" or something like that. You can't connect to is from here, just see that it is advertising it's existence. 2...

Regarding the Bluetooth- On initial powering up of my BMS, the Bluetooth module had a solid blue light, neither my phone or tablet would pick up the device. After much messing around the solution was to unplug the balance cable, disconnect the Bluetooth module, reconnect the balance cable and THEN ...

Just replace the little BT board on the back plane. If it costs you $10, I'll be surprised. I don't need to, they just plug in on my board. I only mentioned it since someone mentioned not being able to connect via Bluetooth. I was offering the possibility of a faulty BT module as a possible explana...

Thanks ElectricGod. That is the same version of the app that I am using. I will try turning GPS off and on. Otherwise I'll have to wait for the seller to come back online.

I did try my old phone which is on lollipop. Same result

Also, can someone upload a recent version of the android app and pc program please?

I finally received and wired up my 16s 60a Bluetooth BMS from here: https://m.alibaba.com/product/60619821174/Wholesale-bluetooth-bms-RS485-60v-60a.html Unfortunately I am unable to connect it to my phone. I can see it's Bluetooth name as 'minew' but it refuses to connect to it. My phone is Oreo, bu...

Thanks guys. I've edited the original post to amend the incorrect term.

The laminations are not damaged, it's the coating on the copper wire that is damaged. I'll put a small dab of super glue over it like major suggested.

I opened my MXUS v3 and noticed a small scrape on the varnish of the copper wire. I tested the continuity with my multimeter and it shows a short to my phase wires. I'm not sure how it happened, it doesn't seem raised enough to be touching the side plate. Is this a major problem or will this cause a...

shorza: how heavy is the swingarm? It's too expensive, when I was 2 years ago in Australia I sent a 25kg package for 250 AUD - Brisbane to Slovakia... It took 3 days

I can find for you the shipping provider

9kgs all up. It would be great if you could. Thanks.

If you cover shipping yes. I can not cover return shipping from au and offer one more free shipping to you. So If I cover shipping the frame back you you, you will send me a black Storm frame with 135mm swingarm at no cost to me? I think this is my only option. It is going to cost me over $150AUD t...

I will cover price of shipping this frame from you to Australia address and will return you money. Deal? We don't have 150mm atm. I can't send you 135mm as you have custom color swingarm. I can just refund as I said in previous message. Artur, I am happy to take a black 135mm swingarm but it appear...

I've got the same frame and motor. My frame should be arriving next week. Hey Shorza, if you switch the pinching plates to the inside is there any threads sticking out? This is a real bummer I was really looking forward to this frame. As it is at the moment, the is a few mm's of thread sticking out...

Shorza just so you know the 135mm version barely fits the 28-30mm stamped steel DD hub motors they make in it with 1 small washer on each inner side, it is steel so some people would just bend it for 150mm, but I wouldn't be up for the task What motor are you using? I agree that fat bike swingarm i...

motor with 150mm axel means motor with 150mm axel. motor for 150mm dropouts means motor for 150mm dropouts. bending the swingarm means the dropout plates will have a V-shape or are no more parallel. Now think what happens if you tight the nut's of the motor axle.. true, but if you bend it 5mm from ...

mxus v3 motor with 150mm axle how did you plan to use 150mm dropouts swingarm with motor that has 150mm axel? i hope you understand 150mm dropouts is a size between dropouts from inner side. Our standart swingarm is 135 that you can easly pull to 145.. The one you have is 164mm, and can pe pulled t...
