    1989 Kawasaki EX500 (Ninja) - EV conversion, finished but still refining

    Preferred is subjective. I prefer a hub motor: quieter, more efficient, easier for me to install, no custom chainline to sort. But I also do 100% street riding and commuting and I don't need crazy low end torque, and I don't mind the extra unsprung mass of a hub motor. What is the preferred...

    1989 Kawasaki EX500 (Ninja) - EV conversion, finished but still refining

    This is correct, I know it's hard to see, but yeah, it's the rear end of the swingarm, which itself typically has to be cut to allow the hub motor to slide in

    Generic aliexpress parts, nothing fancy. I have good regen settings, so I only use the rear disc brake in emergency stopping, and it still works fine...

    Apparently ChatGPT can help you write code / programs?

    Because I do little to no coding/programming, I see very little that an AI can do for me, personally. However, I'm very into self-hosting and just hobby homelabbing for fun, so i would still love to set something up local on low power just to play with. As I said before on this thread and...

    Please keep thread discussions to topic; you're more than welcome to start a different thread regarding legality of different powered controllers and hacking them. We'd rather not have to lock this thread to cool it off.

    Apparently ChatGPT can help you write code / programs?

    NetworkChuck is really good at dumbing down concepts and projects, so much so that they're too simplistic. I actually don't like his content for more than the first 5 minutes that gives me enough knowledge to search for more detailed information. But its good enough as an overview, thanks for...

    Are you using ollama for the local hosting? Do you have equipment to measure power draw during longer requests?

    Grounded modem and DC-powered server; causing internet connectivity issues

    I upgraded my 15-year-old modem, and i also installed a ground loop isolater on the coax cable going into the modem. Couple days now, and no connectivity issues. Now I can actually run my DC-powered home server as planned!

    Grounded modem and DC-powered server; causing internet connectivity issues

    You mean, the 120vac-to-12vdc power adapter? You're saying there's a chance i could give it 48vdc instead of 120vac, and still get 12vdc out? I have a dozen 12v adapters laying around. This might be interesting.

    Grounded modem and DC-powered server; causing internet connectivity issues

    I would typically agree with you, except in this case, my server is a mini 1L pc that would be ordinarilly run off a standard 20v wall-wart-style power brick. I don't have an oscilloscope, but I would guess that a 48v-to-20v converter is no worse quality than a 20v PSU. But in any case, I agree...

    Grounded modem and DC-powered server; causing internet connectivity issues

    As I'm thinking more about it this morning, I thought of some new search terms that I hadn't before. If I install a ground loop isolator between the modem and the coax cable going into it, would that help?

    Grounded modem and DC-powered server; causing internet connectivity issues

    Posting here on the offchance that someone might know what's going on. I have a number of devices in my house powered directly off my 48VDC battery bank solar system, via converters. This is a good setup because I only have a 2000w inverter currently for those devices that can only be powered...

    Converting Home's - RV's to DC

    Agreed. I have a quarter of my house running directly off the 48v nominal DC, via various converters and such. Which is great. But take a dryer for example, it averages about 4000w. If I ran that off 48v, it would need 83 amps on the cable, just for that one load.

    Using rooftop grid-tie solar during a power outage.

    This is the way, I've done the same with 5000w of solar at my house.

    Using rooftop grid-tie solar during a power outage.

    This all sounds good and correct. If you end up going this route, please do share how you decided to switch the panels, I'd be interested to see it.

    Using rooftop grid-tie solar during a power outage.

    I believe OP is suggesting putting some sort of splitter between the panel and the inverter, before it goes to the grid. Thus, he's after the panel's DC voltage, anywhere between 30-60 volts depending on the panel.

    Using rooftop grid-tie solar during a power outage.

    In addition to a splitter between the panel and inverter, you would also need some sort of a switch; you will want current to go to the inverter or your off-grid setup, but not both. Your problem, should you choose to take it on, is that what you're planning is almost certainly not going to be...

    2008 Polaris outlaw 525s ev build

    Use the 3d printer as a stencil for cutting metal, like I did. I also don't weld, and I cut my motor mount just by hand with an angle grinder out of 10mm aluminum. https://endless-sphere.com/sphere/threads/1986-daelim-trac-hawk-moped-conversion.122092/#post-1784283 3d printers are great...

    Is there a decent 24v conversion kit ?

    You need to put some shrouds or something over the back of those two batteries so that they look even more like jet engines than they already do.

    I had an issue like that last week with ANT BMS: loose wire that the computer interpreted as one cell being 2v and the next being 5v, and shut down.

    This was me, and I apologize. It threw up a lot of red flags for me, and it was so far off from your normal posting style and content that I was sure it was a hack. Very sorry about that, you did nothing wrong, you posted in 'general discussion.' If you repost I promise I won't delete it this...

    Dozens of pallets of new LFP cells from ESS bankruptcy - SOLD

    You'll notice the ends are big beefy copper tabs, able to diffuse a bunch of heat. And LFP in generally is good at handling short bursts of heat, more so than li-ion. Therefore, you can solder these. Could get some pretty beefy connections this way. For example: You'll still want to exercise...
