Quick question - embarrassed to even ask. If a battery pack has a 5A charge BMS, can I use a basic 2A charger? I don't like the idea of using a bigger charger you see as I read that fast charging can be dangerous. Thanks

Senquan, have you made any progress with this?

@Bikes4two how do you find the gearing on the Pendleton? I converted one to electric and I find that I'm out pedalling the gears very quickly. That is, I seem to pedal faster than the bike expects and so above a certain speed (say 12 mph approx) I'm pedalling but no torque, no gain. I get that...

Sure, SEQURE SQ-SW2 welder. Just worked fine.

I've been testing the battery on my commute. Range and reliability are my two main needs. Running through the miles so far with over 30 miles and half battery remaining. This is on 4 as standard and 5 on hills. I'm one who doesn't see the point in using pedal power if you've got a battery. So I...

These are LG M50LT 21700 with 5Ah and max discharge 10A I've attempted the copper/ nickel plated sandwich and will need a more expensive welder. Also, have read through the forum thread (thanks) and it seems that, even with a KWeld, many are having hit and miss with the strength of the weld...

Thanks. Had a read. A lot to get my head around there. In your 21700 build - are you completing a single weld of both copper and NP combined? Or a weld of copper plus a weld of NP? - you've cut copper squares rather than strips/H? All fine? Thank you again

This is great feedback. Thank you. I'm going to look more into the copper and nickel thing. Any reason not to use pure nickel (rather than coated), other than price? Many thanks

Hi, I have completed a 10 Ah battery and, as well as my own learning, would appreciate thoughts and improvement suggestions relating to safety, performance and electrical maths. Key points: 10S2P using branded 5mAh cells Daly 20A BMS Waterproof Common Port 30A Internal Fuse 0.15mm nickel...

How? Lol You replace the bullet connectors, I'd assume?

How are you connecting to KT controller using the XT60?

Ah, yes I see now. Final question if I may. On/off switch. Do you rely on the lcd for power on/off? What would safety protocol say? Thank you for your patient insight.

So I sourced a Daly as I wanted the waterproofing and now realise it is common port. Regarding the charge, what connection are you using to go from XT60 to a common charger? I am using XT90 but can only find this with a male charging connector. I would have thought that it would need to be a...

Great instructables. Where is the charging cable? Would you not have a charging cable from the BMS? Thanks

How might this be secured within a frame? I can see where it may sit but how to stop it rattling? Presume an exit hole would be needed to be engineered?

This may depend on the motor used in the Swytch wheel. Does anyone know the motor and controllers used?

Hi pedelecs, Anyone with experience of hub motor noise? It sounds like a consistent but relatively quiet rattle. I've removed the motor out and the gear cogs could be more flush. There is a 2-3mm gap near the circlip which allows the gearing to give across the axle a little. See image...

Thanks. It is covered in coating but, with your advice, I'm thinking of pulling the wires out and injecting silicone to double protect any chance of a short. What do you think?

I'm looking at this internal controller at bmsbattery Rather than have to manage wiring that is not needed (throttle, brake), how can I reduce the cables involved? Can I cut close to the board and just heat tube the ends? Any ideas welcome please. Thanks

http://www.szktdz.com/en/news_show.php?article_id=485 Is this not exactly what I'm looking for? KT Bluetooth dongle? Assuming it works with any KT controller? Seems difficult to find. Can anyone add any background or insight, please? Best wishes
