Hello, Some months ago I've read somewhere that the Sanyo NCR2070C 20700 3500mAh - 30A is an excellent high power cell with a very good life. Can someone test it to see if it's true? Of course it has lower capacity but it has smaller size also. Maybe it's a good candidate.

What??? You've spent more than 30-40 hours to create the version 1 and also you've built a new battery pack! How could you sell it so easily? If the difference will be only the new motor then you could just change the motor.

Hello, I was in Israel for four days. Three in Jerusalem and one in Tel Aviv. The reason I am writing here is because I was impressed of how many e bikes and electric scooters you have!! I haven't seen so many electric vehicles in my life before. The most of them are low power ebikes from 250...

I can see clearly that at your last two videos you were driving much more carefully. Bravo! By the way why have you installed the extra black-red handlebars ? Are they to carry a child ? To carry your shopping maybe or to rest your feet when they get tired ?

check this guy from Poland, he can rewind your qsmotor with more cooper for maximum performance. https://mobile.facebook.com/CyklonEbike/ or you buy a new one with a working temp sensor this time and you won't have the same issues.

Can you tell me how much money did they ask to see if it worths to send it also for repair? To be honest after what happened I don't trust the controller so much because it happened while I was riding and it was dangerous. You are lucky because yours had a quiet death. Also if you consider...

Good morning! What has happened finally with your MaxE? My midi-e failed last week while I was riding, I was lucky that I wasn't going very fast because it has blocked the motor. I think some of the mosfets are dead because the battery cables have shorted out. Do you have any idea if we can...

Great Job! Now you can race your friends or other bicycles without for them to know!

Very nice job! if you use ebike brakes like tektro dorado the ones with the thicker discs you won't have to replace pads so often. Also regenerative braking helps to reduce the problem.

Wow this ebike looks fantastic! I have some questions. Is this a conversion ? you have matched the rim color and everything so nicely, it looks complete! The thing with the sparks above the motor is it just for design or it does something ? Is the battery pack into the gas tank ? Are you sure...

With so much power at your fingers don't forget to post some videos from your first wheelies!

With simple maths: For 30Qs you have maximum named current 7P x 15A = 105A For 40Ts 7P x 25A (from real tests) = 175A So for exactly the same setup 40T cells will stress less they will run cooler and they are going to live longer.

its a very big mistake for a high power ebike not to have a working motor temp sensor. Maybe the characteristics of the windings have changed because of the high temperatures and you don't know. With the hand you can't really know the inside temperature.

I agree go for 40T cells. I am going to use them for my next battery pack. At the moment I have a 20S-9P made by 30Q cells, still works but it sags a lot and my concern is that it doesn't have lot of cycles. Generally speaking 30Qs cycle life is very poor. let's hope 40T will last longer. So...

Thank you guys, I am happy to help when I can!
