    Ferrofluid/Statorade maintenance or not??

    I've been using it for 2 or 3 years, yes you have to inject another 10 ml or so every year or so. I suppose it depends on how often you use your bike. I use mine almost everyday 10 miles per day. I think eventually it dries up/spreads around in the motor after a year or two.

    Statorade effects

    Yes and after a year or two you need to add more, I am at that point. What sucks is it costs 25 dollars with another 20 or 30 dollars just shipping from canada to USA. Hopefully they will get it back on Amazon to purchase. I saw a note in 4-6 weeks they will get it back up on Amazon hopefully...

    LTC6811 Implementation Thread

    Look at Altium Circuit Studio, a slightly less fancy version than Designer, but almost the same user interface. It does everything you need, autorouting,3D, same as Designer, it probably uses the same underlying engine. You don't need a $10K layout/schematic system, that is for laying out...

    Fuse-wire for individual cells, DIY Tesla style

    The wire looks fragile. I don't know if it would ever make it on a home-grown bike. He's doing packs that stay indoors and dont move or bounce or shake.

Turns out they pulled the phase wires down so tight with zip ties to go out the axel one rubbed on the edge of the motor inside circular frame. it eventually (2 year old motor) rubbed and shorted to the metal of the motor. I can see the vaporized deposits...

    Adaptto Mini-E/Max-E Owner's Thread

    Update On Vibration Problem with Adaptto: After working with Oleg, it was not an Adaptto problem, but a burned/shorted? phase wire inside my motor. It was odd because it started severe vibration 4 days after I installed my new adaptto, so I assumed it was the controller. I am really happy with...
