The grey wires are brake sensors. Leave them disconnected for now. Make sure everything else is working before connecting the brake sensors

Post some pictures.

??? if you knowinging buy a 500W or more then yes, but Tongsheng make 250W TSDZ2B too. They have EN15914 certificate for them. I know you don't have the TSDZ2B, but you should check the label and their website, they make 3 versions, 250W, 350W and 500W. Some sellers make slightly untruthful...

seriously though, there is a real need for sub £20 EVs.

When you switch on the lcd on the tsdz, the software goes through a calibration routine using the stored torque calibration value in the LCD. That is why it is recommended that you switch on the lcd when not pressing on the pedals for 2 seconds afterwards for the calibration to complete. The...

My TSDZ2B has the standard 48V controller which is the same in all those advertised as 500W and 750W TSDZ2B. The difference is it is restricted to 10A continuous, 15A max. Those advertised as 500W and 750W have been programmed with higher max current. My TSDZ2B comes with a full throttle but you...

No. Your kit and mine have the same small antitorque washer.

Price of LFP per kwh is about £120, so 50kwh don't amount to much. There is good margin in power wall storage batteries.

BTW, is anyone watching the covid enquiry? Most of the stories are already known but they still give me a chill. How can a country like ours can be at the mercy of that useless bunch of public school boys is beyond me.

Tesla is going to make a £20k ev, tesla model 2 in Germany next year or 2025. I reckon they'll sell like hot cakes.

it may be still worth considering for infrequent use compared to the cost of a full kit.

the risk of damaging the tool battery when used to power ebikes is much less than the other way round, using your bike battery to power a lawnmower for example. The LVC is set in the controller, usually 31.5V. The overcurrent is usually non existent, controllers are usually set for 15A max. The...

it's still worth considering using a tool battery for e-bikes. You can build a good and cheap e-bike using my BBTS kit (£100), a motorwheel and a tool battery.

I watched a yt video last night about tool batteries. The main theme is there are 2 signals, one to start the battery and one to stop it. Those batteries can supply insane currents, much higher than those we see on E-bikes. The guy pumps 75A from his tool battery. So if you want to use your...

Interesting read and useful experience of a bike that is now 2-3 years old. Thank you lenny.

The 48V TSDZ2B that I sell has a full throttle. Head over to https://wooshbikes.co.uk/?tsdz2 for details. If you want to climb hills without pedalling then use the throttle.

have you thought of torque sensing with a hub drive? it offers the same natural ride feel of a torque sensing kit plus the lower cost of a hub drive. My BBTS kit without wheel and without motor is on sale for £100 at the moment. You need to add to that a wheel with 9-pin connector and a battery...

I am a risk averse person. Also, I can't knowingly create a potential trouble spot for Andy here who has to sort out problems later.

I wouldn't do that. Your mower needs to know that the battery is working in its safe zone. If you gives it false information, something bad may happen. Yesterday on BBC Breakfast, there was a call for mandatory third party testing of batteries and making compulsory that the battery talks to the...

it's difficult to say if the M100 from Ananda will cope with 20A. I believe in not pushing things until they break, leave alone the question of how to sort out whose liability it is for the broken kits. Also, I think 48V 15A, that's 720W input, is equivalent to the Boasch Performance and more...
