Okay, how about that Cycle Analyst internal battery resistance function, does that tell anything if it shows same values like it always do about 0.050-0.065 ohms depending on battery stress and temperature? It takes longer time to charge from 60v to 84v than normally but otherwice charging...

The battery was charged via the normal charging port just like I normally do and first when I plugged the charger wire into the port charger started and stopped immediately so I unplugged the wire and put it back in, I have to repeat this a couple of times until the charger stayed on. According...

Yes, thats how I normally do, charging before riding and longer breaks are somewhere about 50%. Battery is not self made so all I know is that bms is only for balancing when charging. Time will tell is there any problems in the future... :) Thank you guys at this point :thumb:

It seems that battery keep its voltages, now after 24h there was exatly same voltage than yesterday. There is bms only for charging so nothing is limiting discharging all out. Have I understood right that fire risk is only when using battery like charging or driving but if it sitting in the...

Yesterday I noticed that my bike battery seems to be drained almost empty when I switch it on, there was little light in ca screen but no numbers. Bike was sitting about three months and all that time tranformer of the headlight was on. My mistake. Battery pack is 20s9p 72v li ion with LG hg2...

Luckily you are here to tell that :bigthumb: Things can get pretty bad with motorcycle if there is bad luck. So you continue with MAC, is this new one also 5t?

Thats good to know that it does not heat up a lot from the outside surface even if there is a statorade inside. Once I had Crystalyte front hub motor without statorade and what I remember it get quite hot from between the spokes after high speed run when I stopped and heat began to come to the...

Bullfrog, have you already purchased an motor?

Yes I know that video but I haven't watched it yet, just little. Thats why I haven't bought the motor and controller yet because making it working good is not simply thing necessarily. I wish that I could drive daily/normal driving with rear motor only and front join in only when needed. Like...

Hello, I haven't been here lately and it seems that there has been new discussion here so I apologize for the late reply. My situation is that I have now QS205 4t with 24" fat rim. My earlier motor was Mxus 4t with 26" fat rim and acceleration from 0 to 70km/h was 7s and now 5s with QS205! So...

Has anyone experienced this: https://nexun.pl/pl/p/QS-205-v3-3000W-30x4-Ferrofluid-Tyl/382 Kv about 10 and ferrofluided from factory, I have never heard that and also Google does not regocnize that?

That is powerfull and good looking build! Torque must be insane with 16" rim and those current levels. Usually that current is used with Qs273 I think but it is good to see that smaller 205 will survive also. At this point it seems that 4t is best option for me. Big weight of motor is little...

Yes Mxus is 45mm and QS 50mm so there is little torque benefit with QS wider stator. I also believe that Mxus 4t will saturate with current I use. I say "believe" because there is no test results to see what is the real limits of the motor. QS might also saturate but later than smaller Mxus so I...

How about this: If I using QS205 v3 with kv 11.39 and little smaller rim I can get more acceleration from start to stop even if low rpm torque is smaller? I cant get 3.5T version like Jonno recommend because of my small battery so this might be compromise. How accurate is that simulator vs...

So it seems that you have lot of experiences with ebikes :thumb: What I have understand if I put lot of current for fast speed winding motor it is getting stronger in lower speed yes but best improvement happen in best efficiency area which is higher speed area in 3t motor. So in my mind if I...
