I have another one with one cell group blown but I have lots of salvaged cells to fix that as well .

3 light up top one flashes . Hold the button down 30 seconds or more all light come on . I just tested the Suntours controller there is voltage the battery is working but it will not charge .

Ripped not propped lol

Dave I have these Two batteries attached. They are for the Carrera after your model but before the latest ones. They are both balanced the far one in the picture is outputting 40V at the discharge port and will run a motor using a KT controller but the BMS will not allow it to charge from...

I think the older Carreras are better I was planning to rebuild this , not going to now 20 inch frame , oil brakes . 700C wheels better for the road . I will try pop down after the weekend with motors and BMS boards too.

I have been talking to an engineer at topbike kit about this he also agrees to abandon the Suntours BMS and suggest Hailong ones because of realistic budget for the the Carrera batteries, but then we have to change Controller, LCD, PAS because of the Comms system . For DIY this works but for...

Oops

This is overall length 150mm it’s on a pre 2021 Cross fire if you look how out it protrudes from the frame I think the shorter one may fit

I will have a look over the week end I got quite a few of them

You probably have a pre 2019 Vulcan

I would think it’s will not Not can not . The very high failure rate of Carrera Battery BSM’s at 500 and 550 a pop you would think they would support some small independent battery companies being able to offer repair out side of the Warranty. I have spoken to many angry customers who can not...

Here are Dave eBay item number:236309336979

The Suntours is from early Carrera bikes the other one is from later bikes I think they both fit . I am having to put lots of cheap parts on e bay at the moment as they have sanctioned her business account because customers kept buying used used Carrera batteries after I asked them not to . So...

Yes the amount of people I try to steer away from Suntours and put on kits is a lot . But you can not fault Halfruds for there marketing and Sales campaigns. I had a customer send me a Suntour Carrera battery this week 2 year old bike used 10miles the on and off button on the BMS is faulty so...

Hi Dave I might have One Do you have a photo of what you need I have a few Suntours BB and lots of the later silver ones putting them on e bay today .

All the posts and photos are good but what I am sort of getting at is say in London speed is around 20mPH on average but some roads are 30 , 40 or 50 MPH speed limits. With the modern technology of electric only bikes the size and weight of some of the better built fat tyre or snow bikes the...

So a realistic power to speed ratio for say one of these fat tyre bikes ie some decent range from battery’s and say a 750W motor could be limited to 40mph to make a viable electric moped that could still be peddled to your destination if you ran out of battery . I know of people using these...

Who’s who I would think never checked , We only have grey squirrel’s on Hampstead Heath , I call them foreigners when I explain to my foreign wife that they pushed out all the native squirrel’s . When we go to Vietnam I am the foreigner more and more of us now over there too . But if I...

Yes the one on the chain wheel bolted to the side is problematic if the bike owner does not keep the crank clean and serviced , they tend to seize then the sensor moves and breaks . Also they have rubber seals that fail adding to the seizing problem. The Suntours BB combined PAS sensor is much...

Ok so just had a thought the latest Carrera Suntours Crank and Pas works on light and is a Torque sensor. Does that mean a Suntours BB PAS sensor would be a Candence sensor ? And does this mean it does not use light inside the BB ?
