Re: battery percentage indication not right.

because it is based on voltages of cells.
real SOC uses Columb count , meaning charge going out and going into pack.
circuit for this can be complicated with dedicated chip.
Stromer ebike or Bosh ebike or Yamaha EBIKES would not use such cheap ways to measure SOC.

Re: How much power is too much power? (hub motor)

riding Townie bike at 75km/h with stock V-brakes is insane and suicidal I must say.
there is simply not enough braking power to stop this thing
at this speed you need motorcycle type of brakes.

Re: Dash cam

Re: Cruise control switch

NOT on my ebike drive.
while in CRUSE mode I can use throttle as many times as I like and it still stays in CRUSE,
of course pulling brake lever engages regen and CRUSE turns off.
I ride on EPLUS ebike drive.

Re: Why no V-brakes on Fat Bikes?

I am amazed that very often in discussion about v-brake versus disc brakes wearing out of rims is not mention.
with V-brakes you would have to replace worn out rims sooner or later
imagine cost of quality rim plus labour on lacing wheel?

Re: ni-cd to lipo

I understand you are limited in space inside this RC car.
I am sure you can run this on 8V , 2S 18650 cells /charged to 4V/cell
if there is enough room use 2S2P combination of 18650 cells.
