Re: Dogati Electric Superleggera

They look like Maxxis Hookworms. They remind me of Aussie Jester. He loved those tyres. Sadly not available in 24" anymore afaik.

Re: Potting Batteries, Thoughts and Experiments

most of the couriers (like Fedex, UPS) have an internal policy that they will not accept any lithium battery only shipment without it going as Class 9 Dangerous Goods cargo. Yeah, that's what happened, despite our best efforts... However, there is another category of batteries packed with equipment...

Re: Potting Batteries, Thoughts and Experiments

Probably not much use to you now, but I would argue they are not "batteries not inside a product" as the LiGO is a finished commercial product/domestic device: A product that contains a battery (it's a casing with a battery inside, a BMS, lights etc) no different to a USB power bank for charging up...

Re: Potting Batteries, Thoughts and Experiments

I finally have my Ligo in hand Ligogo.jpg For a battery that Cathay Pacific allows 26 of in hand luggage it sure was hard to get into Western Australia. Apparently we are Ligo phobic over here. Not the first time we are a little backward in moving forward. This is a direct quote from my friend who r...

Re: Weight Sensing Longboard with Inline Wheel Motors

It's big news. Best skateboard in the world with that equipment. The man hours that have gone into developing that my mind boggles. This is the next era for ridables right here. Throttle, controller, batteries and motors are all executed so well. What a package.

Justin you are a fkng legend. This is an outstanding product and a big leap forward for lithium batteries. Not just for ebikes but for so many aplications.

Re: Custom RV120 for ebike use: group order Rv120-ES edition

Well, as you know you get what you pay for. And that is the point. If the 160 Pro does do 12kW for the $600 price tag, that is a damn cheap 12kW outrunner. That is what T2 would discover for us, and then we would all know. This is what he is offering and as a bonus the person who purchases the motor...

Re: Custom RV120 for ebike use: group order Rv120-ES edition

Is anyone taking up Toolman2 on his offer a page back, to build a dialled in RV160 + controller combo? Timing is not right for me but if it were, I would jump at this. It is a generous offer and we know T2 is good for it. To receive back a race tuned set up with a lot of hours put into it, and all y...

Re: Idiots guide to rewinding Revolt 120 pro

Nice job on the pliers. Love it. I hope that the timing board will make it easy to find the perfect hall position, if it can be improved in the first test then i will open motor and readjust the positions - i don't plan to use the motor on my bike with the timing board connected. Do you have an osci...

Looking good larsb. It's fun to watch your progress. I noticed you were chasing down a timing board. I commend you on your ambitions to acheive good horsepower from this motor.

Re: Adding hall sensors to outrunners

Sensor set up is the same no matter how you have it terminated, you should be fine there.

The rest I am not the man to answer you, but how much current it will pull is going to be a function of your load ultimately. This is where you gearing/reduction is important...

Re: Adding hall sensors to outrunners

Do you have the data sheet for the hall sensor? You just parallel the + and - to the 3 sensors and then run out your signal wire. That will give you your 5 wires for the controller. 5v + and - and your 3 signal wires :)

Re: Adding hall sensors to outrunners

As long as they are 120 deg apart it will work, that is just place them at 3rds around the stator like AW mentioned. I did this on a few 80/100 outrunners ans it worked well. Where it is on the winding will affect the timing, as in if it is advanced, neutral or retarded. I remember Thud saying advan...

Re: build your very own Lebowski controller !

There's not really anything to change when moving to lower voltages. Of course you can use lower voltage caps and FETs (which may need a change in gate resistance based on different gate charge) but other than that it should be OK. I do not know the efficiency of the controller, I do not have a mot...
