Any of the KT sinewave controllers and displays(lcd) will work, whether 6 or 9 mosfet, all that matters is one makes sure it has the 9 pin julet connection.
For PAS simply stick to an 8 or 10 pole disc.

Hi. Here’s a link for the controller
Here’s the display
Here’s the PAS
Personally, I'd get this pedal sensor because it's £10 cheaper. It'll probably fit and work directly. In the worst case, you'd have to unclip a couple of wires from the connector and slide them back into a new position.

That's brilliant thanks so much for the info, I'm going to order them tomorrow.
It's on Amazon marketplace, not sold by Amazon themselves. I suspect it'll arrive from China. There may be extra charges.

That is a good price for a 17a kt set up.

Just in case your unaware/unprepared, that pas sensor will require the removal of your bottom bracket to fit, an easy enough job with the correct tools but a pita to bodge up without the tools.

The Mk 1 kit had a Hall sensored wheel but after the first controller failed I was advised to use a work-around cable on the replacement controller which bypassed the Hall sensors. The (12A) replacement controller has worked OK for several years now, and gives the modest assistance which I want. P.

It is Yose branded so generally can be excepted as a good option, from the few specs supplied and the price one can assume it is using 50e cells in 10s4p in config.
Thanks for that, I'm going to order that battery, and see how I get on. When the project is complete I'll post the details so other Swytch victims can change their set up.

Hi Just came accross this 36V 20Amp Samsung battery on E bay https://www.ebay.ie/itm/304786418154 anybody got any thoughts on quality ??
That's a Yose battery. I'm sure it'll be fine, but wouldn't it be better to buy one direct from them to avoid duty, or are you not in the UK? It looks a bit expensive to me at that price plus possible duty, when their 17.4ah one ships from the UK at only £201, and the Greenlance 48v20ah batteries with Samsung cells are only £290.

If 'the Swytch' is a folding bike the 17.4Ah is NMC, the one RtJ linked to will be a lot lighter as well as from an established source.

Both batteries are from Yose, so the same "established source", and they both weigh the same. Samsung cells are NMC, so that's the same too. The only differences between the two are the price and capacity.

Direct from Yose the 21700 50e 20ah battery is £260.

Does £260 include delivery? The Yosepower.co.uk site isn't listing a 36V20Ah and the .com site says it can't deliver to my address near yours. Website glitch or favouritism? :)
Ebay shows 3.5kg for 20Ah vs Yose 5kg for 17.4Ah, and for 20Ah 4.2kg, not wildly different if ebay's wrong and it usually is.

You can always calculate the weight of a battery. 18560 cells are 50g each, so a 17.4 ah battery will be 10S6P, which is 3.0kg plus about 0.7kg for the case and BMS. 21700 cells are 70g, so a 20ah one will be 10S4P, which is 2.8kg plus 0.7kg for the case and BMS. The two weights are therefore 3.7kg and 3.5kg. The difference is equivalent to £2.70 in loose change (lightest possibility, not all in 2ps, before some smart &$$ chimes in).

I sell the 48V 20AH downtube battery for £300 delivery included in case anyone is interested. The cells are top notch A grade Panasonic 21700.
