sweet that's just what I wanted to hear. Thanks.

I know the BBS02 is rated for 25 amps, but is that the absolute max? It won't ever trip the overcurrent protection on a Daly 30amp BMS right? Also I really don't want to go to a bigger bms, because the battery I am attaching it to is a 15ah Panasonic 3350mah build. Those cells are rated for...

Try testing the motor with no load on it. While riding my bike I can't tell any difference between medium and high, but when I flip the bike upside down and run the motor, the motor definitely speeds up going from medium to high. May be a torque issue.

There is a controller on aliexpress that has 2 sets of phase wires/hall connectors coming out of it. Unfortunately it is very underpowered, only 13 amps per motor, or 26 amps total.

The regen brake on my ebike was more then capable of bringing me to a stop if I applied it early enough. I had a programmabIe controller so I set the regen current up to 50 amps, which is higher then most setups. I also gave it its own button so I could regen brake without using mechanical...

I built a battery pack using the liitokala lii 50E's recently. Russia youtuber tested them, this is his result: https://youtu.be/mXOg3mCTYcc?t=1132 They won't explode at 3c discharge, but instead of getting 4.8ah you only get 3.5ah. I got around this by building a enormous 13s10p battery so...

Ok thanks :) I'm liking it so far, I have it hooked to a 48v 38 amp Xunlida sine wave controller and it really goes now. It gets almost hot on the outer shell, which I suppose means the oil is working. It's not leaking anywhere either, other then where the wires come out of the axel.

Sooo...I thought this all sounded pretty cool but I'm not wading through 25 pages to get all the relevant info I need. I had a spare swx02 motor and some silicon glue and decided what the heck. I used a unmarked dispenser bottle to inject oil through the disc brake hole. On the swx02 at least...

If the motor is running poorly try using the self learning feature. It is 2 green wires. Connect them and turn on the controller. It will slowly spin the wheel till it has figured out the correct settings. When it starts spinning good, turn off the controller and unplug the green wires. Also I...

Build Pictures! https://i.imgur.com/ffQ5VvV.jpg https://i.imgur.com/5PyMvy3.jpg and on the bike: https://i.imgur.com/XX6n8i0.jpg I forgot to take a picture of the cladding I put on it. But it was 2 layers of cardboard and 1 sheet of aluminum all cut to shape on every side. That bulked it up a...

So I tried out using brass and it didn't work either but it has a different issue. The brass strip welds to nickel and ni-plate easy but the strip easily tears away from the welds, leaving 2 little brass buttons where the welds are lol. I assume the brass is simply being melted straight through...

Nevermind LOL out or curiosity I tested to see how strongly the copper was welding to the batteries and was able to pull the copper off with little effort. It did form some bond but I was able to break it with the strength of my fingers. Oh well, I'm just using a modified sunkko 737g anyway...

So I'm building my first battery and was curious if my way of paralleling the batteries was sufficient. https://i.imgur.com/6gtSsdI.jpg I originally wanted to make cutouts of my copper sheet that would cover the whole area but I found that it took a lot of pressure to get the copper down into...

Ok thanks for the information guys!

Lets say you have 2 identical 5p packs laying around. They each have one low quality 30 amp BMS. You could wire the discharge cables together to create a "10p" pack with a effective 60a rating. But you will bypass one or the other bms when charging, which is bad. Among other things; the cons of...
