From landrover Discovery SPORT iEWD 2021. 7 x 48V modules each 12S1P Samsung SDI. Connected in series. for a 400V system. I want to use them for an off grid solar storage system. There appears to be a BMS per module. But I don't know if these work without the central control sytem. Now...

UPDATE: Grin is sending a new motor in warranty. It has apparently happened before with 9C motors, but some years ago.

Yeah, not going to fix this. I can weld aluminium. but even then. I would need to clean up the threads too. And the risidual welding stress is not great either. Bulllits drive very well, they are some of the nicest 2 wheel cargo bikes around. You can make tight turns with them and lean in like...

So I managed to kill a RH212 motor from grin. I recently build an electric bullit. (My second e cargo, first one on 2 wheels) And as I have some more disposable income I did not skip on parts. Bullit frame, Alex rims. Magura mt5 hydraulic disc brakes 72V 34Ah battery, with samsung cells...

More looking for premade batteries with type approval. I could build them. But not sure how class approval would like that. And it would take more then 200A these are 800hp 16l 6 cil diesel engines. Theoretically it need 250A at 24V but I think at least double that to be safe given the...

Lithium starting battery recommendation? What is the go to brand for lithium starting batteries? Looking for starting batteries for a 13l 800hp marine diesel. Engine has a 7kw starter so at 24V pulls about 300A for 30 seconds. But recommended lead acid batttery would be 800-1000CCA. Note: this...

Anyone here ever use this: https://www.amadamiyachi.eu/products/micro-tig-welding ????? Is this something I could do with my AC/DC tig welder. Setting the startupcurrent high but short and the welding current to 0. I can modify a torch to have the conductive base as on this image. I can try...

OK Update for anyone having a similar problem. In reply to you questions. Yes unloaded speed measured with an extra speedometer was only 19 km/h. I replaced the controller by this one http://www.pswpower.com/ven.php?cargo.2016-3f-33c0 My speed is now 30km/h on throttle only, 34km/h on pedal...

I have a list of the controller functions. The only connectors not used at the moment are ebrake and pas. The only setting I'm unfamiliar with is P07 "magnetic poles ratio" It tried changin it anywhere from 10-80 but it didn't have any effect. I didn't find a max rpm. Only a max speed which I...

Thank you for the reply. I tried adjusting the wheel size to as low as 10 ". But my supicion it is just a shit controller is thus confirmed. So with a 25usd sinewave controler I should be good? http://www.pswpower.com/ven.php?cargo.2016-3f-33c0

I have an older sparta emotion C4 ebike. Which I keep as a spare to my main commuter ebike. The bike has a sanyo CMU9 geared front hub motor and runs on 36V Recently I somehow managed to fry the original ananda controller. :cry: Pictures: https://photos.app.goo.gl/THCSQSFndmZjPD5R9 I...

I've used air powered tools under water before. But this would need more torque at a slow speed and more portability. An airpowered motor of 500W would take a serious compressor I don't want to haul around. Ik konw the center is stationary, that is the whole idea. Ideally the motor would be...

Aditonal idea, If anyone knows a slow rpm geared hubmotor with the cables coming out the end of the axle. Then I could just machine sleeves that screw over the threaded ends of the original shaft leaving the original shaft intact. Less work for the same result.

I would like to build a handheld rotating brush to clean the hull of my boat. Something like this: http://www.maxdepaz.es/clonar/wp-content/uploads/2017/08/2-e1528796902220.jpg On a much smaller scale. I could drive it with a belt from above the water. But having a geared hubmotor in the brush...

Hey guys, I'm in the same situation. I want to replce the controller and display of a sparta E3. (Presently 3611DLC controller) What controller did you end up using? Matching plugs?
