The seller sent me another controller, and I tested it today. No change. The seller is wanting me to verify that I have the parameters set correctly, so I am going to verify that with what they sent me. I do have doubts that it is a parameter issue though.

Ok, another question. Assuming the controller is the only thing that went bad here, and the new one fixes it, how accurate are the watt meters on these displays? I'm thinking if he is going up any questionable hills, he could toggle that on to monitor when he was pulling too much current.

FYI, this is the kit I used, and I purchased a 13ah 48v battery to go with it: https://www.amazon.com/gp/product/B08KDRXKPZ/ref=ppx_yo_dt_b_asin_title_o04_s00?ie=UTF8&psc=1

Yeah, I think getting it out of the bag is a good idea, although I'll have to figure out a mounting plan. Not sure on the motor temps, but I do know he was pedaling and not just using throttle.

This is the controller specs, sorry that it isn't more clear, but that is taken from the Amazon listing. Looks like the voltage is 36/48v, rated current is 11a, max is 22a. I don't think he was running the motor too hard, of course I wasn't there, so I can't be sure. He just said he was in...

Hello all! Just did my third ebike build for my brother, and decided to do a 500w 48v geared hub motor kit for his fat tire bike. The install was easy, and after adjusting some settings, the bike was running great. He came over today to check it out, and we went riding around the...

Battery is a Wallen Power from eBay. https://www.ebay.com/itm/283905457800 Just heard back from them, and this is their reply: Yeah, BMS is usually installed on the left or right side of the battery. And a metal heat sink is sandwiched between the BMS and the battery case. So when the...

Just got back from a week long camping trip, and noticed that one of my 48v 13ah batteries gets quite warm while charging. Seems to be right around where the BMS is, and stay warm around the first hour or so of charging, then starts cooling down somewhat. This is using the stick 2amp charger...

My instructions were very weak to say the least, and did not cover any P or C settings. I did download a full set of instructions, and watched some videos, but some things still aren't very clear. Cables should be here Thursday, so yeah, thanks for suggesting those, as I had no idea they existed.

I was designing this before I found out about the magnetic cables, and think they might work better in my situation. However, someone may find this useful, so I uploaded it to Thingiverse. https://www.thingiverse.com/thing:4609780

Ah, ok that makes sense. That's what I thought, and that's how it works on my geared bike, course it has the S830 display, which I wouldn't think would make any difference. I know I do have something off in my settings. On the S830, using throttle will match what PAS setting you have. Like...

No, what I mean is that the PAS doesn't give as much boost as the throttle does. On my geared hub bike, they are equal. Like, if I am going up a hill using PAS, and start slowing down, I can hit the throttle, and it will give me a little boost. On the geared hub bike in this scenario, the...

I just tried this (P3=1), and I do like it better. I'm still wondering about my PAS strength, but knowing that I can give throttle while peddling does help, almost like a little turbo boost! Still, it would be nice to not have to do that. I'm wondering if it has anything to do with my PAS...

Yes, I think so. I think the geared hub motor on the Townie is just a different animal. Using the PAS on it, I get the same speed/torque as if I am just using throttle, and the DD motor just doesn't feel this way.

Yes, sorry, I meant laced on a 29" wheel.

Thanks, I did check there, but they don't have anything 48v geared. Still looking though.

Found them on Amazon, Prime shipping!

So, me and my infinite wisdom, put a 500w geared hub motor on my Townie for street use, and a 1000w direct drive hub motor on my mountain bike for trail use. I was hoping that the extra wattage would make up for the lack of torque in the DD motor, but alas, that is not to be. Went on a 7 mile...

On both of my ebike builds, the shifters are integrated into the brake handles, so I cannot swap them out. Thought about printing some type of holder just for the switch itself, and hacking it on my existing levers, but I'm wondering if these are really needed? My thinking is, if something...
