    New bike build hill climbing

    Yes I regret a little I didnt buy 20ah. Maybe Ill try to expand parallell. And yes better unload and go twice. Even the rims or something else could brake. I also have yet to install ampere/volt instrument. Its almost Connected after 4 years haha.

    2x 1000 watt hub on lead acid

    How is my current setup compared to if I would buy another battery, 26 amp hour. Bms rated 35 amps 1500 watt. Could I connect my 13.5 in parallell each with same bms 35 amps 1500 watts. This would mean two bms on one motor and one bms on the other. Anyone elaborate on this? I usually ride...

    Bike suddenly wont start

    Got new display. It said 36v on the bottom. I tried anyway. Led was on for one second. Now dead. There are cables between the display and controller. Took some photos and attached. Guess the cables could be faulty somehow. The controller and motor still works if I change.

    2x 1000 watt hub on lead acid

    Ok thanks! Reason why I need torque at lower speed is that I travel short but have very steep hills. Its a cargo bike with hub in each front wheel. I prefer climbing the hills slow. I normally use little throttle. More throttle doesnt help. I have to assist a little on the pedal when unloaded...

    2x 1000 watt hub on lead acid

    I guess I cant change the amps without new controller and then there is risk of broken motor? Im considering batteries like Two 48v10ah litium. One for each motor. Or One 48v litium for both. Not sure on how much ah I need and if I should look for anything more in the specification. Or Four...

    12v lead battery suddenly drained.

    Im trying to find somewhere to buy a dc dc 48volt -> 12v. I guess that would solve my problem? Im about to add even more stuff. A led ramp with 126watt so I guess I need a dc dc which can provide enought current? Is this dc dc overkill...

    12v lead battery suddenly drained.

    Hmm I charged so the drained battery is 12.9 and The other 3 are at 13.1 and 13.2, 13.2. I moved the lamp to the 13.1 battery and now when I charge I have two batteries at 13.2 and two batteries at 15.7... I hoped I couldav had the lamp still on one battery and just use the individual charge...

    Hello :) I have a bike with 4× 12v batteries. 48v total. I installed a low watt led lamp on one battery because it is 12 v. After a few charges I noticed the battery with lamp didnt charge much / at all. It was 12v and the other 3 batteries were 13.7 each. What the frock?

    New bike build hill climbing

    Thanks for reply. Yes the bike is fast and strong. But I have a very steep hill at home and when I load the cargo box up with alot weight the motor is at the limit. Almost at a halt so I need to assist alot with pedal. Can it be the lead batteries that arent enough? Here is URL to batteries...
