November 4, 20232 yr This is the battery https://www.aliexpress.com/item/1005004209965815.html as you can see I'm not great on computers.. Silver fish seems to me to be a starnge choice. You need a special frame to fit it. It'll look terrible if you strap in on somehow. Why not get a downtube or rack battery?
November 5, 20232 yr There is no info or specs at all that I could see, worth looking on ebay as well. Typically as mentioned they are for special frames with the battery vertical behind the seat tube , typically freego bikes and some folders.
November 5, 20232 yr Author This battery looks to be best suited to the bike https://www.amazon.co.uk/Battery-Lithium-Downtube-Charger-Electric/dp/B09WR41CHZ/ref=sr_1_3?crid=3TGMPPXS9QW37&keywords
August 24, 20241 yr I have designed a solution to allow an external 36V battery to be fitted in place of a failed (or poor capacity) Swytch battery. It's a 3D printed housing for the controller and UI pad, which fits onto the handlebar connector. I sell it on eBay... https://www.ebay.co.uk/itm/166874946938 It replaces the bulky 'handbag' with a more compact solution, that securely presents the controls to the rider. Other than running wires to a new battery and the battery itself, all necessary parts are included...
December 15, 20241 yr Just got a kt controller with an lcd9 display to replace my Swytch Brompton kit. Using the Swytch motor. What's everyone using for the P1 setting on the controller? It is based on the number of magnets multiplied by the gear reduction ratio, and I have no idea of these parameters for the Swytch Brompton motor. Please help? .

It is based on the number of magnets multiplied by the gear reduction ratio, and I have no idea of these parameters for the Swytch Brompton motor. Please help? . Probably too late to answer. I asked Gemini. Suggestion is to use a value of 96 for the P1 setting. https://g.co/gemini/share/39b55dbaf5c1 I have a SwytchBike Brompton kit for my Decathlon 20in bike. I'm considering replacing the failed controller to a KT controller with a KT PAS sensor. Can you recommend any specific variant and how was your experience with the replacement? Thanks!

My advice is not to get one with waterproof connectors. Apart from that, they're all more or less the same, except the low power ones can be 24v/36v or 36v/48v. Obviously, go for 36v/48v unless you have reason for needing 24v.
