If you still don't know this new VESC, now introduce 75V200A dual ESC Ubox from Spintend!

Hi, Friends I’m John Lee. I launched my new product Ubox(based on 75V/300A VESC) for some time, but still some builders don’t know it. One of my customer said “you come out from no where, but gladly you’re here in market” . Yes, I’m not here before. Now I’m here to do simple introduction of it . (if you already see this post in other forum, you can skip it ) Firstly I’m an electronic software engineer , I just integrated some features in VESC that many people may need in riding. Here is the product picture. 75v200A Ubox based on VESC and its perfect partner remote Uni1 The unique features are:

  1. Integrated 2.4ghz receiver and bluetooth in it. In this way, it will save more space and no much wirings.
  2. Be compatible with 75V/300A VESC firmware.
  3. Electronic on board CAN BUS Switch. You can turn on off it by button or by remote Uni1 control.
  4. Dedicate 12V output socket for horn and light and other extended function as user may need
  5. Reserve BMS port, support BMS data detection and monitor of each battery cell
  6. It has all other VESC features: FOC /BLDC mode, regenerative function…will not list here.
  7. It supports to be used in authentic vesc tool.

In order to be better fulfill Ubox designed function, I had to redesign a remote that can make all function available. Here is Uni1 remote picture. (Considering the supply of the remote case, I will consider to make my own)
