Looking around I've seen people go back and forth arguing about 13s or 14s, and 13s is ideal for arrangement in my case. I can confidently fit a 13s8p battery in my frame, but 14s8p would be a little tight. Wanted to hear from people with more battery experience than me. I've been using and maintaining E-bikes for a few years now but this is my First battery build.
I have been looking at CYC motors for my e-bike build and they seem very solid, but the price is a bit high for my budget right now. I have seen other mid-drive motors on Alibaba, Amazon, AliExpress, eBay, and similar marketplaces that look somewhat similar to CYC but cost almost half as much.
Has anyone here tried a cheaper motor from these marketplaces before eventually upgrading to CYC? I do not want to waste money on something that will break quickly, but I also cannot afford the best option right now. I am trying to decide whether it is smarter to wait and save up for a CYC kit or try a budget motor first and upgrade later.
I would really appreciate hearing about reliability, power delivery, maintenance, and long-term durability from anyone who has gone the budget route first.
Trying to get my 3dprint cnc milled in aluminum but when I send it through an online stl -> step the manufacturer says they cannot make it due to broken surfaces. they can't "print " aluminum but can print in stainless 319.
it Prints perfectly on my adventure pro 5m, slices fine, tried in freecad to export it to step but they don't accept it. I literally don't see what they're complaining about.
I have files and photos upon request and really want this in aluminum - anyone know a cheap / decent aluminum 3d printing service or can tell me what's broken on my files would be greatly appreciated.
Hello everyone and thanks for the help in advance. I have an OEM ebike 250w 36v 10.3A and i wanted to upgrade to something powerful. In my head, i wanted to try to keep the old battery ( even if really bad and lasts 15 miles already on 250w PAS) and then I considered to buy a 36v 500w. But because i thought was not enough upgrade, i finally ended up buying a 1500w 48v to downgrade to 36v from the controller (even having knowledge about some speed/power limit).
Now, I assembled everything, first 2/3miles on 36v is fine, after that, the screen (SW900) gives me error 06, which probably means low voltage due to the battery. So I decided to move it to 24v instead. The bike is flying, gets the right watt with the right energy, the problem is, even in 36v or 24v the battery never drops down, which doesn't give me the change to understand the capacity left.
With 24v at some point, the bike turned off and the battery start to blink red and blue, no idea what it means (pinnacle e bike) but even from unplugged from the e bike, it keeped blinking, i had to put on charge to see the blink stop after 20 second and start to charge.
Now, starting saying i know neither solution are great for the hub. But is there any issue, on setting the sw900 on 24v using a 36v battery? And what do you think that blinking mean? Overheat? Undervolt? Battery empty?
Would you suggest to buy a 48v battery to resolve straight away the issue, or try to investigate if it could.be some thing else (like faulty motor)? Even if the symptoms are pretty clear.
Thanks guys for your help
I’m thinking of installing a 1000w 48v kit on my bike but I was just wondering if anyone has any experience, are hub motors safe for off-road? Not like big jumps, but just riding on trails and dirt roads. I heard vibrations can cause lots of problems.
