Thanks, so there is only 7.5A between each cell, that load is uniform all the way through the pack (sorry for noob question)? I was thinking about sandwiching copper between the cells and the nickel-plated-steel for all the series connections, I've read some fascinating stuff on this forum...

Cheers thanks for that, so (same snaking layout) like this with the balance leads? and this layout presumably means I'd need to be careful of shorts here: What would be the best way to insulate against that?

Hi all I'm planning a battery build that requires the cells to be laid out linearly. Like so: I know this layout is a pain and not ideal, but its the only way they'll fit in the cavity... NB: I'm not planning on building this myself, hopefully getting it build professionally, so just...

cheers dude

Cheers The motor is UART, so I can set 'Low Battery Protection [V]' parameters to something appropriate for 52v (say 42v) and I've got a C500 display which toggles between different voltages, so all good in that regard - essentially it's the same setup as I have on my BBSHD. I strongly...

Hi all! I’ve pretty much finished my M620 build, the only thing I need is the battery.. The motor has a 48v sticker on it, it’s the UART version, so I can easily change the low voltage parameters. I’ve read here that a 48v M620 can easily handle voltage from a 52v battery. I’ve also read...

Hi Can anybody recommend a reliable and really compact 14S BMS? Or have any ideas? I’m designing a new battery case for my bike to replace the stock solution, and space is really tight as I’m trying to squeeze 56 21700 cells into the down-tube. The bike has Bafang M620, limited to 30A max...

Ha! Don't know what happened there, have pasted a picture in instead.

Hi I was wondering if anybody has any experience with these hydraulic e-brakes (or anything similar)? https://tinyurl.com/4nsdvjze <- link broken so pasting a picture I retrofitted brake sensors to my BBSHD, but starting a new M620 build and wondered if this was the way to go. Cheers

Thanks My question on voltage was more because I don't want a 52v motor nannying performance if its reading from a 48v battery, but conversely don't want to brick the motor by giving it too many volts. I've read here that a 48v M620 can easily handle voltage from a 52v battery, but a 52v M620...

Hi all! I’m about to pull the trigger on a Bafang M620 build and wanted to check some of my assumptions with you guys: I’m ordering a 48v motor, I’ve read here that this is the best option as I could run that with a 52v battery if I wanted. That’s a better idea than ordering a 52v motor and...

No worries, we’ll if you do find a Scott frame and you figure out a decent approach to the TAs let me know! :D

My Scale 950? Looks like its got a 39t on there at the moment, with little or no room for anything bigger

Thanks, that’s good to know. One have a TA on the one side?

Thanks for all the replies. So you guys think something custom-cut like this wouldn't do the job, then running a bolt through the same hole as the derailleur hanger? I can see it'd stop the wheel falling out at least, and probably stop the dropout from spaying, but as you can see there isn't...
