5. 120A Fuse Information:
* Electric Features:
Spec: 60Ax2 (can be extended to 180A) , 100V
Connector: Amass XT90PW female and male connector
* How long time will it blow?
It’s placed on positive power line
For 120A fuse, the blow current is 240A in a minute; continuous time under 120A is more than 4 hours.
Fuse data sheet:
% of Ampere Rating(In) Blowing Time
100% * In 4Hours Min
200% * In 60 Sec Max

* How longer can it last if my battery spikes over 120A?
Here is a curve to show how long time it will last in certian current.

* Is 120A enough ?
1.Most of electric skateboard are not working at 120A battery current continuously, usually they are low curent, and burst current in a short time. And in the PCB it is easy to add one more fuse to extend the current to 180A.
2. This fuse current spec is for battery current, NOT for motor phase current. The current of the VESC is anchored to the running current of the motor. The supply current of the battery will not exceed the running current of the motor, and in general, the current of the battery will be much smaller than the current of the motor, especially when the motor speed is relatively low. Of course, if your motor is running at high speed and under high load, the current of the battery may be close to the current of the motor. At this time, you may consider to estimate how much fuse current you need under this situation, and the fuse can be extended to 180A at max.
* How to use it ?
Connect it between your VESC and Battery


6. And why do you need an adapter in applying a VESC in ADC mode?
* The ADC input of ESC(based on VESC) is in float mode, and there is no filtering measurement. If this input port is left floating, it is easy to be interfered by electronic interference, and ESC will be misjudged by the signal voltage that requires the motor to run.
The symptom is: the throttle is unstable and easily interfered; if the throttle ADC input is unplugged or the throttle cable is disconnected, the ESC(based on vesc) is very easy to continue working to control the motor and can’s stop it.
* Most of the ebike and scooters thorttle on the market are 5v, and such throttle control signal is accordingly above 0-4v, while the working voltage of ESC(based on VESC) is 3.3V,so the throttle signal voltage exceeds the upper limit of ESC (based on VESC), it will affect the normal operation of ESC, and even cause ESC failure
* Due to wiring complexcity, it’s easy to wiring wrongly and damage the ESC.
FAQ:
1. Will other VESC be compatible with Ewheel ADC adapter V3?
Yes, it works with other VESC and normal ESC(Non-VESC), but still have some difference on the power supply for the lights/horn function.
Ubox(single /dual) : there is 12v power supply port(fan port), which can supply power to the ewheel ADC adapter’s output parts(horn and lights etc.)
Other VESC: mostly only have 5v output, you need to source 5v horn/lights to work with ewheel adc adapter V3
12. E-wheel ADC Adapter V3 Product Details
All in one function adapter for diy Electric skateboar Escooter with VESC :
* Horn, Head light, Turn Signal light, Brake and rear light, and reverse light support.
* High, middle, low, 3 level throttle support.
* Motor reverse and cruise support.
* Buzzer to remind turn and settings.
* Support both hall brake and mechanical brake input.
* Support bidirectional throttle(two-way throttle)
* Two / one motor drive support.
* Each output port (for horn/front lights/turn signal lights/brak lights) max current is 3A,12V
* Size: 63 x 53 x 12.5 mm (same size with V2 adapter)
* V3 come with: Cables (2pc* 8pin UART cable, 1pc* 12v 3pin cable, 5pcs*3pin cables,12pcs *2pin cables )
* What ‘s upgraded from Adapter V2?

* Function Port:


Notes:
① Only connect one this UART cable in Ubox, it means two motors run in same step.
② Connect both two UART cables in Ubox, if you want to run two motors independently, then need to turn off Ubox internal can bus
③ Cruise function works by a swtich
④ Reverse funftion works by a switch
⑤ This kind of brake lever has internal swtich, it can trigger on the brake light
