Re: Kelly Controllers Configuration Program - a Definitive Translation

Thinking about this more, I don't think it's regen I'm after. I'm wanting to dull the throttle response so when the level is all the way out 100% throttle is 100% throttle but with the level in a little I want full physical throttle to be 50% throttle.

Re: Kelly Controllers Configuration Program - a Definitive Translation

Thanks for the response. Not got round to giving this a go yet, I did start trying to design and 3D print a housing for a pot but I might just save time and buy the linked part. The idea is on my ETrails conversion to have a lever where the clutch lever was to control the regen not sure how it'll wo...

Re: Kelly Controllers Configuration Program - a Definitive Translation

Anyone used BRK_AN? I'm looking to have a traditional brake lever operate a pot to control motor braking.

Re: Gas Gas Trials bike conversion

Please do. I'd be interested in what motor, controller and cells you're using. Along with reduction ratio.

Re: Gas Gas Trials bike conversion

It's running well and I'm pleased with it. I want to lower the motor a little, tidy up the wiring and I've yet to sort out anything in regards to bulk charging.

Re: Gas Gas Trials bike conversion

Motors running again now, with an external 5v. Hopeful get it all back together tomorrow. Eastgem are apparently sending a new magnet, but I think it might be wise to try source some myself. At least now it's not such a black box any more and I've learned a bit about linear and bipolar hall sensors....

Re: Gas Gas Trials bike conversion

Good news, I put new halls in the for the motor and applied an external 5v and the motor spins. Bad news is it's at a fixed speed so either I've also blown the halls in the throttle or I've buggered up some settings.

Re: Gas Gas Trials bike conversion

They had me pop the back off the motor while talking to them on Facebook. If they we're a UK company I'd be expecting more help, but my expectations are low dealing with them. I'm just itching to get out on with my lad on his Oset now it's the holidays.

Re: Gas Gas Trials bike conversion

I've no idea about the magnet nor what's dead inside. Properly gutted as I was thinking I'd be riding it now, I only had a few little bits to tidy up. Still not sorted with bulk charging, but I was itching to get it out and could live with splitting the pack for now. I've read the Kelly controllers ...

Re: Gas Gas Trials bike conversion

I've found what's killed my halls. https://s33.postimg.cc/7lvmqysy3/IMG_20180723_171334.jpg the loose bit of magnet. Bad news is I don't get 5v on any 5v lines of the controller and one of the RTN connections isn't connected to the rest like the manual states. Struggling with communication with East...

Re: Gas Gas Trials bike conversion

Looks like I might have a hall sensor issue. I wasn't getting 5v on any of the outputs when rotated. I popped the back off the motor and one of the sensors was too hot to touch. Not sure why I didn't get a reading from the other 2. Hopefully when my replacements arrive and I've soldered them in plac...

Re: Gas Gas Trials bike conversion

Not a clue at the moment. Not changed anything since it worked, it's a shame really. I've finished my battery box and a proper motor mount, just went to test it before tidying up the wiring and the controller is throwing throttle error and hall sensor error. I'm going to test both this weekend.

Re: Gas Gas Trials bike conversion

I'm not getting much time to work on it, but I've just about finished the battery box. My temporary motor mount needs replacing with something a little more sturdy as it moves a little. I've turned off throttle smoothing and its move lively. Short test video: https://www.facebook.com/groups/electric...

Re: Programming Kelly KBS Controller

Anyone able to offer any hints? I'm not able to get the software to connect to the controller, the software that downloads from their website on the link for the KBS-E links to KBS-X. My controller is Kelly KBS 7218EW and I've used https://www.ebay.co.uk/itm/PL2303TA-USB-to-TTL-RS232-Upgrade-Serial-...

Re: Gas Gas Trials bike conversion

I've not had chance yet. I think I might be able to go down 1 more on the front with off the shelf parts. I'll get a larger rear CNC'd if I need one, just need to learn how to do sprockets in fusion 360. I've got to finish mounting the battery packs before I can give it a good test.

Re: Gas Gas Trials bike conversion

Can't get a larger rear. The 70t is the largest black sprocket available in 428 apparently. I'd maybe have to get something cnc'd or change chain pitch. Motors got a really strong pull, I'd like a bit faster initial ramp up if I can.

Re: Gas Gas Trials bike conversion

What ever was already programmed in to the controller, I've not yet played around with it. My motor alignment is still a little out so it's still a bit noisy. Hoping to get it hooked up to the laptop at the weekend and play with the settings a little. I might want to increase the gear ratio, but for...

Re: Gas Gas Trials bike conversion

It's a bit of a stab, but it says the max rpm is 4500 so I've used that to try and gear it under 30mph. The reality is that I cannot get a bigger rear 428 than 70t and I've got a 10t front, so I've gone with that to see how it feels. If it's not puncy enough I'll have to look at yearling the control...

Re: Gas Gas Trials bike conversion

I couldn't get an answer as to its KV but I went with it any way. It's almost 9kg so hopefully that means it's got some grunt.

The throttle is http://www.eastgem.net/throttle-adapter.html my rear sprocket should be here in next few days and I'll have a turning wheel and a little test.
