:arrow: From what I found, AGM batteries are waterproof, but they also have a valve that they use safely. Apparently when the pressure of the H2 released in the battery becomes too high, the valve activates. So when I reload them I will have to tilt the mounta...

So, I posted on EValbum, but it's not online yet. And here is my only image from which I will draw inspiration for the chassis and the other "home" parts: https://www.econologie.com/fichiers/partager/1220634870EOWlLf.JPG After the chassis I will tackle the wiring. .. It will take me...

for the batteries they are two waterproof 12volt 18Ah agm battery, on the manufacturer's site, he specifies that they can be put down.
Which would allow me to house them under the board and save space.

I get into chassis construction this weekend, I will put you pictures.

For the controller I made a photo comment: The 3 wires out for the control by potentiometer 5Kohms. https://www.econologie.com/fichiers/partager/12201854824NpmLb.JPG here is for the controller, this is the command I will study to curb a little, given the 5Kohm potentiometer, I need a...

It is made by Chinese, the mountain board in 800w. For my battery it will be 2x12volt in parallel, so a total of 12volt 36Ah for 432watts. 600/432=1,38 times the adviser discharge. With the controller clamped to the command, it will be nickel. Also, I want to stay on 12volt to put...

800w in 36volt (3x12v 12Ah)!

Now I have everything, I even find a bike computer in my archive

And for the battery, lead-acid 12v 18Ah in series, so in total 12v 36Ah.

All I have to do is assemble and adapt everything, it will take some time, see you soon for the proto photos ...

I also said that I would put a two-position switch, one for autonomy (not fast) and another for 50km / h, we will see what it will give

I will be vigilant during the tests, no worries

not bad, but 100w is too fair. and my drive wheel is not 26", it's a 6,5" pocket bike wheel, I need at least 50km/h and torque, I've already settled this issue with the pinion-crown transmission. Then, the controller limits the consumption of the motor with the potenti...

There must be a reducer inside (2600T/Min), and I will connect the motor output pinion to the crown of the rear wheel, by chain. Otherwise to come back to the battery, I looked in their report in pdf, https://www.econologie.com/fichiers/partager/1219576143xSI05f.JPG with the c...
