Uk based battery builder?

I'm in the process of selecting parts for a winter project, and I'm going to be needing a 72v 40ah battery capable of around 100Amps. I will probably be sourcing the cells (molicel or Samsung) and the relevant bms, I'm still doing my homework before I decide. So it will be just building the pack and...

Re: Bafang 750w rear hub motor max Power?

When I had more of a think about it, I'm thinking that 3000w max would be a better fit, so max 50a. The bike is very similar to a super 73 only longer and more cafe racer inspired. And as far as components I've got plenty from downhill and enduro builds in the past and a new unopened set of magura q...

Re: Bafang GO62 60v controller

The latest update for the sabvoton controller is they have started to use the tf4 cable with waterproof higo connectors that Bafang also use. I'm not sure if the pin configuration is the same but at a quess I'd say yes they are because the tf4 cable is as close to a standard the diy community has.. ...

For parts only 5 brushless controllers

I've got 5 brushless controllers non working for parts only. They range from 48-72v with 60v and 90v caps, that are all sound, also the fets are all good too. They've all come of various builds that I've done for people and we're replaced with new. From memory 3 of them had a 5v error, 1 overheated ...

Re: Red rocket the uk's answer to the super 73

Max speed: motor provides assistance up to 15.5 mph. Deal breaker. Get the frame. Or one with full suspension. If you read the info about the models the info. On the 750x doesn't mention that it's even 750w, I'm guessing that it's because of the 15.5mph UK law. It's actually capable of just over 30...

From the one YouTube review the stand over height is 31" I'm only 5, 8 so it's just about perfect. I've ridden a different bike with the same seat/ suspension set up, and they're better than expected, it's going to be my commuter anyhow so with the 4" tires and the sus seat, it will be eno...

As it comes for about a year, then probably a full electrical swap. I've got a 60v 23ah battery here so maybe a controller upgrade first? I'm waiting for a reply from them regarding what motor they're using to see if pushing it would even be possible. It would be easier and cheaper if they would sel...

Re: Red rocket the uk's answer to the super 73

That's totally my plan to, either a qs205, or 273, at 72v. The more that I look at the Red rocket I'm actually preferring it over the super 73. I've heard that a few people have managed to just buy the frame, if that's the case it makes it ideal, I'm going to drop them a line to find out more. I've ...

I had exactly the same experience here in the UK, when I asked why he could only answer with your mot in a car, then as he said that a motorbike pulled up to the girl in the next window and he was served without an issue. By that time my patience was a bit thin, so I asked the guy again, whilst poin...

Red rocket the uk's answer to the super 73

I'm looking into something like the super 73, my original thought was Alibaba but after running the numbers it's not worth the hassle, and super 73 to me are the iPhone of ebikes, and are way to overpriced, so after some Google time I found the Red rocket 750x a 20" fat bike perfect for my need...

Re: Alibaba to the UK added charges?

Thanks guys, but I've looked at the numbers and with Vat, customs duty, insurance plus the cost of shipping it over triples the price of the actual item. With ordering the actual bike and then the motor kit, it would work out way to much plus with the amount of time it takes to arrive, I've decided ...

Thank you all, very good info.

With regards to soldering directly onto the cells kind of. The pack I'm converting is a 16s, 9p and are already spot welded, I'm just going to carefully remove 2 from each series row, and when rebuilding just solder the parallel connections. If that makes sense...?

On my original bike I was running a 60v 23amh.battery but the bms blew and I've just had it lying around doing nothing so I'm going to reuse the cells for my next build a 52v not sure on the amh as of yet, I've not got that far in the figuring out of things with the frame.
