    Vesc Tool help!!

    So I just received my Flipsky 75100 and I'm trying to set it up to run my sensorless Heinzmann PMS080 middrive. I downloaded Vesc_Tool3.1 and connected via USB cable. It wanted a firmware update before it would do anything else so now it's running 5.3 and calling itself 75_300_R2. I configured...

    Flipsky communication

    So I ordered a Flipsky 75100 Sunday. PayPal processed payment but I have gotten no email from Flipsky themselves. No order number, no estimated shipping date, no nothing. Sent them an email requesting such information. No response. Is this normal for them?

    Flipsky 75100 or L10 Baserunner

    I'm needing a controller with regen for a small kart with a 36v 1500w sensorless motor. I'm considering either the Flipsky 75100 or an L10 Baserunner. Which should I go with? Or am I way off base?

    Powervelocity 12F controller problem.

    I'm trying to use a Powervelocity 12F controller to run a sensorless Ryobi 40v electric mower motor. It'll run up fine to 3600rpm unloaded, but when I put it under load, it starts glitching and jerking at about 2500 rpm and 500watts. Thoughts?

    Lead acid anyone?

    So I know lithium ion is the current hot stuff right now, but is anyone still running on lead-acid batteries? There have been several reported advancements that are supposed to be coming to market in the next two years. Lead/graphene-acid and bipolar lead-acid to name two. Both of these...

    Controller suggestions??

    I recently acquired a new brushless motor that I am considering using for a future Electrathon car build. The vehicle in question would be 3 wheeled and lightweight. Probably about 300lbs with driver. This motor is only rated at 1400 watts max and is currently sensorless. It is a two stator...

    Air gap, magnet shape, and voltage questions

    So I'll apologize in advance for the long post with lots of questions... Sorry. I'm running a Heinzmann PMS126 axial flux motor in my Electrathon car. It operates on 36v due to my battery weight restrictions although the controller (an ACD 4805) can supposedly handle up to 60v and according to...
