Thank you all. There is so much information about lithium batteries on the internet that it can be overwhelming sometimes. I am always looking for papers from official or reliable sources. One question... After my commute, I take my battery with me either to the office or home so it can stay...

I understand, thanks. I guess there isn't a negative effect linked to charge it a bit every time you ride. If so I don't mind plugging my battery for a while every night (20% of full capacity is used every day). Thanks for your help.

What I don't fully understand is why the battery or ebike sellers don't give that same advice to the buyers. I am sure that plenty of them recharge their packs when is close to the min. Even today at work, one colleague was proudly speaking about his long range battery saying that he only...

Maybe this is the one you are referring to... https://www.google.com/url?sa=t&source=web&rct=j&url=https://ntrs.nasa.gov/archive/nasa/casi.ntrs.nasa.gov/20090023862.pdf&ved=2ahUKEwj3p-DSqKDfAhVTt3EKHaLnBmQQFjAAegQIBRAB&usg=AOvVaw1lJieF0Nq3JpcRp3DTzTjV From NASA in 2009. It reads as follows...

Hello all, I just got a Stromer e-bike and after reading all the advice on how to keep a healthy battery, I have one question. The bike comes with its charger (also branded Stromer) and during the charging process, you can see a progressing bar from X% until 100%. I have read that in order to...

Thank you daffy99 for your message. It made me re-think the whole situation. I contacted the traffic office in Zurich ("Strassenverkehrsamt") to know what is the process I would have to go through to homologate an e-bike built by myself with a powerful motor like the Mxus 1500W. Their answer...

If I understand well, the sweet spot is at the top of the efficiency curve and the ideal situation is when the speed I am planning to cycle falls right into that spot. Am I right? I learn more with one of your replies than with 1h reading by myself :shock: Thanks.

Hello, I've been playing with the simulator for a long time today. Am I doing the right thing to compare two motors? - I set the motor, battery and controller type. - Vehicle parameters: 700C, MTB and 100kg. - Human power set to 125w - Grade: 2% All these specs above are equal for both...

Thank you guys. Because I am not even sure of that :? It will be my first e-bike, I know I would like to go fast but not sure how safe I will feel going at 40 km/h in a bike on flat terrain. I would say that my goal is to average 35-40 km/h but after reading the forum I believe that after...

Still trying to assimilate all the info in the last 55 pages. Thanks for the detailed review Neptronix :thumb: Do you know if all the benefits from this Leaf 1500W are applicable to the 1000W version as well? The vendor claims that the less powered version efficiency is 90.5% but I would like...

That's a very useful lesson there Amberwolf. Appreciated! I thought PAS, torque sensor and regen were some features available depending on the motor you choose. I see they are not. I am going through Neptronix's post regarding the LEAF 1500W motor. It is a ton of information to digest and...

Thank you for all your replies! I learnt quite a lot reading you. Finally I decided to go for the DIY option so I can learn even more and fix anything that may fail in the future. I opened a new post to ask you all the doubts which arise in the building process...

Hello guys, After overthinking the whole issue a bit too much, I decided to start building my own project using an old bike. I am a bit lost with numbers, Amps, volts and the like so I will be updating this post with more doubts in the future. Let me give you a picture of the initial...

Thanks Neptronix, I did not intend to go for a low power design. I want to go fast for commuting, being able to keep around 30-32 mph for around 40-50min. and avoid the risk of frying the motor. Do you believe that the Bafang G310 could handle that? I found the LEAF which seems like a good...

Thank you for the debate guys. Honestly, never paid too much attention to this "buy locally to limit the risks" and never had problems. But recently, my expensive mobile phone bought from a huge Chinese supplier broke down and I am going through a nightmare trying to communicate with them...
