Got some parts with this months modest ebike budget.
$50 as pic'd. I gotta get me a job.
Now I can build the pinching drops. yeah
I should have this bike running on my 16s5p 26650 cellman pack next month with its original controller/throttle.
It ran 50+kph on the 200lbs Scooter. I hope I can get 60kph tucked on the @ least 1/2 weight ScootBike.
More to come.
I have been pondering Lipo use for an age @ this point.
Had this cracked open & went to dreamin.
Each compartment offers 150mm x 100mm x 100mm. + a lil wiggle room.
12 of these would fit with room to spare, in the original battery case.

Running 18s4p 66.6v+ 16ah pack. Just over the coveted 1kwh.
Would give me approx 65-70kph. Comfortably over the coveted 40mph.
I found the 10" scooter hub to run roughly 1.1 kph per volt under load on flat/no wind.
Trusting the original scooters instruments was foolhardy. It indicated 65kph. In reality it was more like 55-50kph as batt. sag.
I have read but not retained the knowledge on how to calculate the kv, maybe one of the master brains can help?
I could also run 24s3p for 88.8v & closer to a 80kph top speed
(accounting for added wind resistance)
Time to do the math.
12 x $45(after wait for screen discount) = $540.
Methods LVC/HVC boards. http://www.methtek.com/2011/11/12/lvchv ... boards-10/
Im a bit of a lazy, but a safety guy as well.(live in a basement apartment)
Plug & play charging/battery medic once in awhile is what I like.
4 x $50 =$200
Charger. http://www.bmsbattery.com/alloy-shell/1 ... arger.html
1 x $170 = $170
$910 + shipping.
Maybe another $200 for connectors/wiring/Batt.medics/misc.
Around $1100 + shipping to roll & charge 1kwh Plug & play,mostly safe pack.
(I understand the dangers inherent with this chemistry)
Next I will do the math on a equivalent a123 26650 pack.
First I eat soup. Lunchtime.
