(e-pok) gas Pocketbike upgrade to C80-100

[zEEz]

The custom axe for the motor is almost done ....

At the moment I'm upgrading mosfets in the controller and providing an external programming connector.
This way I can tweak the settings even when everything is mounted on the bike.
Controller will have 60V and 50A initially ... 3kW .... lvc to 50V to be ultrasafe ....
Future programming test with ready bike will go up to 72V and 70-80A ... 5-6kW

have fun!

The 12 mosfet ecrazyman controller got his IRFB3077 mosfets and
the current limit maxed to 80 A, plus some additional 120°C caps.
Also I added an external mini-Din connector to reprogram it on the fly.
Not it will operate between 48V-40A and 72V-80A

have fun!

Looking forward to this one, very nice work.

Unfortunately it is going slower than expected, but it should see some early test
during the summer. Thanks for the support
schedule is:
1-controller + motor test
2-transmission completion
3-early runs
4-bodywork and final painting
5-final runs

have fun!

...is really suggesting a top performer battery for this bike...
one single 7s3p module for around 300$ would provide a very cool 18s battery
with around 9Kg and 20Ah and 68V ... total badass e-pok would be the result ....
for a projected usage time of 1h fun each charge .... and a top speed in the range of 70Kmh

have fun!

this stuff is very slowly progressing at the moment ...
but initial battery pack is now fixed:
will be 48V - 6.7Ah ... obtained by 2x series 6s HK Lipo packs 24v - 2.2Ah in parallel
with 4x series connected hi-current SLA with 12v - 4.5Ah ...
2x LiPO Balancer permanently connected and charging via 2x 24V - 2A chargers

Total weight of the pack will be 0.9+5.6 Kg= 6.5 Kg quite fine ...
Controller will be set at 48V - 60A giving around 3kW ...
Speed up to 50Kmh will be possible with good acceleration and sufficient run-time.

have fun!

great news!
I discovered that a friend managed to convert part of an internal parking lot
of a nearby supermarket in a full-spec racetrack for electric car models.
So the next goal is to finish the bike in order to go there to practice at
FULL SPEED !!!!

have fun!
