2014 / 1991 Sears Craftman 825 Track Drive
|Location||Quebec, Quebec Canada map|
|Vehicle||2008 Mongoose Blackcomb |
Frame type: 4-bar vertical spring aluminum dual suspension frame
Frame material: Aluminum for light weight and durability
Suspension fork: RST Capa-T6; coil/MCU spring, non-adjustable 75mm
Rear suspension: Adjustable coil
|Motor||Crystalyte model 5305 Brute 5000 serie Brushless DC|
This motor can take 9KW and deliver a torque of 200N.m at dead stop and 120N.m at 40kph.
It's a brushless using hall effect.
|Controller||Crystalyte 100V 90A for brushless motor|
this is a original 72V 35A Start immediate that i moded with 12 IRFB4110 Mosfet. I also replaced the large capacitor inside with lower ESR and larger capacity
|Batteries||432 Sony 18650V (known as Konion).used in Makita, Bionx an, 3.75 Volt, Lithium-Ion|
2.21 Kilowatt-hour LiMnO2
I built this pack myself with engineering knowledge for thermal management and safety protections.
I used many used 18V 3Ah LXT power tools battery pack of Makita.
These cells are 1600mAh each and are mounted in 24s 18p groups.
The total pack give 100.8V fully charged and 24Ah.
can take 10C discharge
no need equalizing!!
|System Voltage||101 Volts|
|Charger|| Doctorbass DIY 1.0kW charger/Balancer|
I take 2h10 for full charge!
I built the 20A rate multi charger.
it is made of 12 DC-DC Artesyn converter that are adjusted to 4.2V and 20A current limit.. all DC-DC are powered by a Meanwell 48V 32A PFC power supply.
|DC/DC Converter||Vicor |
I used some DC-DC to lower the voltage to 12V to supply accessory like headlight, rear light and navigation computer and GPS.
|Instrumentation||-Cycle analyst V2.0 ebike computer|
-4 Voltage meter
-Motor temp meter
-Accelerometer (beltronic racing instrument)
|Top Speed||47 MPH (75 KPH)|
I measured that on flat no wind with my GPS and the battery was fully charged to 100.9V.
|Acceleration||0-20kph 0.53sec!! |
tested with 40 pounds of battery and 6.6kW max
|Range||153 Miles (246 Kilometers)|
At 40kph on normal road I get 200km with one full charge and
|Watt Hours/Mile||21 Wh/Mile |
at 40kph it draw 21Wh/mile
|Seating Capacity||1 adult|
|Curb Weight||129 Pounds (58 Kilograms)|
Fully loaded this bike is heavy but the frame can take it easily.
The acceleration is still amazing!
|Tires||normal 2.1 x 26 and 24inches|
|Conversion Time||I stopped counting|
|Additional Features||This project is the next one after my first trek 960 ebike.|
The goal was to get a lower center of gravity and more room for the battery.
And also having great suspension!!
