Vehicle1997 Sundown PGO Super Fifty
This Scooter had an 60cc gasoline engine, today
is 100% electric, with one 72v 150A BLDC engine.

Motor 72200WP2016 Brushless DC
72v 150A peak (11kW)BLDC motor with 12kg, and a
lot of torque, made in Brazil by Pizzino
Engineering, 2500 RPM on load, isolation class H
(180 degrees C) , neodymium magnets.
Drivetrainsprockets and chain

ControllerKelly KBL96251 Kelly Controls
fully programmable BLDC controller 96v 250A -
with regen.

I have two controllers, I did a test with
Sabvoton 72150 using "flux weakening" and
loved it.

BatteriesA123 Systems AMP20M1HD-A, 76.80 Volt, Lithium Iron Phosphate
24S lifepo4 A123 nano phosphate(3,2v 20A), 76v
nominal, 86v 100% charged.
System Voltage76 Volts
Charger Veibao Power LIFEPO4 Charger
2x Lifepo4 charger 87,6v 5A chinese, works well.

DC/DC Converter
DC/DC 12v 10A converter
InstrumentationPannel with volt meter, Current meter, RPM
meter, odometer, speed meter, digital
temperature meter on stator windings,
emergency switch.

Top Speed60 MPH (96 KPH)
Top speed not defined yet, testing various
configurations of sprockets.

Top speed using Sabvoton 72150 controller is
more than 100 km/h with "flux weakening"
Accelerationfaster than with the gasoline engine, and faster
than cars.
Range25 Miles (40 Kilometers)
the objective of this project is not "big
range", the focus is the development of the BLDC
motor, to get more range is easy, just buy more
batteries :)
Watt Hours/Mile60 Wh/Mile
40 w/km
EV Miles
Start:6,843 Miles (11,010 Kilometers)
Current:8,470 Miles (13,628 Kilometers)
Total:1,627 Miles (2,617 Kilometers)
    As of 8/14/2019
Seating Capacity1 adult
Curb Weight211 Pounds (95 Kilograms)
more or less 100kg.
Additional FeaturesAccelerator made with linear hall sensor and magnets(Pizzino
Engineering), much more durable than potentiometers accelerators.

BMS - Battery Management System for LIFEPO4 Cells, 200A continuous-
400A peak, over current discharge protection, under voltage
protection, over voltage protection and balance function.

The Scooter accelerate very well, is very fun to drive it.

The motor is 72v 150A peak (11kW)BLDC motor with 12kg, and a lot
of torque, made in Brazil by Pizzino Engineering, 3500 RPM on
load, isolation class H, neodymium magnets.

The project is not 100% complete, is always in constant
I'm currently using the controller "Sabvoton 72150" and using the
function "flux weakening" the scooter reaches 100 km/h on flat
ground .
