Re: Max range 40 km, after 5 charges only 15 ???

Nope, no front brake.
and hope that your brake lever won't have miles of dead travel.
What do you mean? (65 km were made that way, but the break lever worked fine)

Also, do you know what's the other nut for? (The gold one). Probably just for mounting/dismounting...

Thanks

Re: Max range 40 km, after 5 charges only 15 ???

just give the cable lots of slack Rotated a few turns the withe nut and...voila! We were right, now running freely with the wheel up the ground, it gives me 26 km/h. The marker never passed above 22 before! Still don't know how to adjust/tune it right. This is not like in a bike, and also it's all ...

Re: Test The Brake Lever Switch help

Unless maybe I missed something? I think you did. Found out that The motor runs only at 29.2 V. So the best solution from what I have seen so far is pending between the 2 options that I mentioned before (investment on a good & costumised charger, or, the small & cheap charging circuit). This one, s...

Re: Test The Brake Lever Switch help

Interesting. Using your charger as a power source and shutting off at your determined set-point. Would not be my choice.(I don't think it allows cc/cv) But if your determined to charge below 29.4 (or have too), perhaps. Beats diodes... As a newbie feel more confortable in a cheaper solution, to lea...

Re: Max range 40 km, after 5 charges only 15 ???

Ok, one more thing. Do you know your battery pack is charged and balanced? When you charge it do you leave it on the charger over night? Yes it is full charged always (LCD shows 29.7 v). Another strange thing is that the total distance meter on the LCD differs a lot from the partial one, better mea...

Re: Test The Brake Lever Switch help

As a battery is often charged without the controller even being attached.
So if I understood you, it is not the controller itself who is stopping the charger when the battery reaches 29.7 V.

Re: Test The Brake Lever Switch help

Been talking to a colleague (electronic engineer) that scared me a bit about trying to change the charger. He says it's all about the controller, that should be stopping the charge at a lower voltage point but isn't. He says that trying to modify the voltage on the charger might result on the 2 A cu...

ets see....24v X 10.4 Ah = (about) 249.6 Watt hours. 246.6 / 25 watt hours per mile ( 25 watt hours per mile is sort of a standard around ES) = 9.9 miles or about 15.93 Kilometers Full charged are 29.2 V, so Isn't that 29.2x10.4 ? Anyway it's only 20 km very far from what the manual says (35 to 40)...

Hi

Can it be a badly adjusted brakes from origin? speed never reached maximum (25 km/h) either, only 20...

But don't want you to break it as you can always just pull the plug when the yellow light comes on. :roll: No I can´t, that would implicate surveillance on all charges, and it is to avoid that we are working on a more practical solution.

Re: Test The Brake Lever Switch help

But with a yellow light and 4 pins? Perhaps it does have an extra charging monitoring system circuit..? Be interesting to see.
Ok will try to open it. Any advice on the zone where I might start to hit with the screwdriver ?

Re: Test The Brake Lever Switch help

Mistery found. The controller let the motor work at 29.2 V. More than that won't start.

Also the charger's light at 29.4 turned yellow (that's when I hanged up). If I would let it continue it would reach 29.7 and stop the charge by itself (turning to green).

Re: Test The Brake Lever Switch help

I think it's the best way. I did found an adjustable charger (yes in eBay too!) like you recommended, but I believe the investment ($70) does not compensate in terms of the equipment quality. Would not be my choice.(I don't think it allows cc/cv) This one does, seems perfect to me: https://www.ebay....

Re: Test The Brake Lever Switch help

Ok, stopped the charge 29.4 V , as expected the charger still had the red light when disconnected. However after LCD reset it displayed 29,2 V. (Had no idea that could happen)

Motor started at this voltage, so one can presume that at 29.4 it will start as well?

If your charger has little rubber feet.. The screws are often under those when you peel them off.
It does not, they exist, but are made of the same plastic of the case.
