Yose kit on road bikes

My advice is always to use a separate controller and never use the waterproof connectors. they're great when they work, but impossible to test or diagnose if you get problems. There's no net disadvantage in having that type of controller.

I have a separate controller (Lishui, came with the kit), it is poor and non configurable! 5 Levels of PAS, only 3-5 are of any use.
My question which model of KT controller to buy, with a LCD3 display? There are quite a lot to choose from on the chinky sites!

Topbikekit sell the 22a S09s in Julet W/P form on page two of the controllers or one can buy from various sellers on AilExp. One can also use the SO6s in 17 or 20a versions though heat may be an issue depending on the riding/terrain, I use a S06s on my town/errand bike with no issues, it is flat free flowing riding.

Thanks Nealh, that was the answer / confirmation I wanted!

The only question is how much power you want. i have 14 amps, which I find enough for even exceptionally steep hills at 48v. At 36v, you'd need 20 amps unless you're fit. The 6 fet ones are nice and small, so they can fit in a water bottle container or any standard controller compartment. The 9 fet ones are bigger, and the 12 fet ones are very big. You have to think about how and where you'll install them.

If you buy a 6 fet and find that it doesn't have enough power, a 9 fet is less than £30 and takes about 3 minutes to install (if you have space) because it has all the same connectors.

Thanks VFR, I have a frame controller bag, so will probably go for this http://www.topbikekit.com/t09s-36v48v500w-torque-simulation-sine-wave-controller-with-julei-waterproof-connector-p-760.html as suggested by Nealh. I currently live in Kent and my routes are pretty hilly, in the next couple of weeks moving to the West Country. That location is even hillier!
The Lishui controller is pretty dumb, the KT have good configuration, and I like play about with settings. With the addition of a LCD3 display it should satisfy my needs!

In a bag, the non-waterproof connectors are better - cheaper too.

With the waterproof connectors controller its just "plug n pray".
Change controller. Change display, plug together job done.

Unless something is wrong, then you've got no chance to find out what the something is!

Cut off a bit of sheathing and get probing with the multimeter..... been doing that for years in comms / electrical industry. Dont get me wrong I can see your preference for solder n sleeve connections, reliability if done properly and one less thing to eliminate if not using plug/socket when fault finding.

But.... for the sheer speed of swapping stuff about (which I'm always doing), I like plugs and sockets
