    Advice for powerwall

    Yeah, I actually got 5 of the ANT bms's running in different vehicles around here, 4 of the "old" types and one of the "new" 21 version. All from same seller, ICgogo or something. Oldest one are 3 years now. All of them are keeping the packs perfectly balanced (even though the 2 that is running...

    Advice for powerwall

    Thanks. I agree, just needed to know Im not crazy for using a handful chinese BMS'es instead of one fancy :lol: That means I can use a Victron battery monitor to track Amps, SOC, and so on, so one less thing to integrate. It will be a 14s, so ~52V. Harstad, I think they have a few minutes...

    My attempt at a lightweight EMTB with torque based PAS

    Sorry, didnt notice the replies to the thread, I havent had too much time for ES lately. On my setup (dont know if any of the colors have changed lately): RPM from Torque sensor is green, connected to Cycle analyst yellow Torque signal from torque sensor is white, connected to Cycle Analyst...

    Advice for powerwall

    Yes, I think I understand and agree. Thanks for your feedback! So what would you do? 6 chinese bms'es or one centralized batrium?

    Advice for powerwall

    I will be hooking up a victron multiplus (possibly 2 in next stage). So I can charge the batteries with the multiplus on nights (in winter) and the solar array (in summer) in combination with the battery will keep the consumption during the day low. The prices differ widely throughout the day...

    Advice for powerwall

    Yes, I agree about the balance leads are often overlooked. I have tried to protect them as good as possible o my small battery packs, but without fuses, it is a pretty big risk anyway. I think i will take the time to use some fuses on the balance wires on this pack. I saw some pack builders on...

    Advice for powerwall

    Appreciate the input! 1. What kind of current do you think such a tab could carry? I am not worried about the balance current, but the current through parallel wires if a battery would have some kind of internal fault. 2. I was thinking about using something like this for each parallel group...

    Advice for powerwall

    Hi guys! I know this is maybe not the main subject of this forum, but there's a lot of knowledge here, so I thought I should give it a go. Long story short, I am building a powerwall, and scored a great deal on a 24kwh e-golf pack. I had limited time to do research, and after disassembling the...

    Votol EM-100 & EM-150 controllers

    I had the same problems and used a lot if time trying to figure out what was going on. Solution? Turned off "low beake" on page 3. I have no idea why, but it is repeatable on my vehicle. Regen on low break signal works without the box ticked, so I have no idea what this box does. Except make my...

    My attempt at a lightweight EMTB with torque based PAS

    Thanks! They are holding up quite good. I've replaced the freewheel on the fatty 2 times, but apart from that, only normal bike-stuff that needs fixing. They are only used for tecnical single trail, so maintenance is quite high and mileage low compared to road-use, but they have reached around...

    Hubmotor hydro generator

    There's a 10ft wide concrete dam at the "top" of the head, so I guess the velocity will be the result of how I build the sluice. I will probably build it in concrete in the middle of summer, the creek is usually close to dry a couple of weeks. The wheel will probably be steel. A breast shot or...

    Hubmotor hydro generator

    I have this creek running through my property. It is only a 60cm (23") head, but it usually flows more than 3000lpm (790 gpm) throughout the year. I know it is not enough to generate a whole lot of power, and its definately not cost effective, but I want to build a water wheel. Mostly because it...

    Electric Quad ATV

    The battery is a 20s1p, and I pull 220A from it. I think the LEV40 is rated for 300A continious, but dont remember exactly. The pack is sagging like 2-3V on full throttle, so they have a lot more in them than I am using.

    Recommend me a controller

    Thanks! I see it is a version on aliexpress called ND72850 which is supposedly 450A battery and 850A phase. I will try to search around a little, but a Fardriver is starting to get really tempting...

    Recommend me a controller

    Guys, I could need some recommendations for a controller. It is about a vehicle that is already converted, and it is almost doing what it should do.... Here's the short version: Old Polaris 6x6 converted with a QS 138 3kW mid motor. I have kept the original driveline and gearbox, so in the "Low"...

    Nanjing far driver controllers

    Are anyone running this controller successfully on a qs138? Im currently running a votol 72150, but am honestly tired of figuring out of all the bugs and different versions of software and firmware. Currently it is running OK, but looses sync above 4500rpm, and lacks some low end grunt... Is...

    My attempt at a lightweight EMTB with torque based PAS

    Only play I have is the freewheel itself, so there are some slight play in the chainrings. Like the tsdz2, but way less. No play in the crankset. Im logging in to your thread in the italian forum once in a while to check for progress 😁

    How about a 3D printer section?

    I like this thread 😁 I bought a 3d printer to print battery and controller box, but ended up wishing I would have bought it before! Such a useful machine. Learnt enough Fusion 360 through youtube that I can print most of what I need. It is free for personal use, you just need to find the...

    My attempt at a lightweight EMTB with torque based PAS

    Ah, I see now. Thanks for explaining! I am curious to see how long it will last. Interesting project, I hope you figure out the controller. The overrun might be better when you put load on the motor. It looks like some of it is just the motor winding down, which takes some time when you have no...

    My attempt at a lightweight EMTB with torque based PAS

    No, the CA cant do that, its a function in the controller. Justin explained it in details, I think it was because you need a constant phase current for it to work properly. The CA can only adjust battery current. You need to make it past 2 poles in the torque before it will start assist. You...

    My attempt at a lightweight EMTB with torque based PAS

    BTW, fatty is up and running again with DT Swiss rear wheel and some new rubber for the winter that is coming. I also printed a thing from nylon for the derailleur. The SRAM derailleur has always had an insane appetite for absolute every kind if bushes that gets close, and I grew tired of...

    My attempt at a lightweight EMTB with torque based PAS

    Ouch, 3-4 seconds overrund doesnt sound that good. Any way to program it? And how is the motor you converted running? Its a very interesting thread, but google translate makes it a bit hard to get all the details :p

    My attempt at a lightweight EMTB with torque based PAS

    Thanks! The PAS is working a lot better than I was hoping for, actually. I have it setup so the response is very fast (fast throttle ramps and only one or 2 poles averaging if I remember correctly, and zero ramp in the controller). This works great up to around 2.5x human input. Anything above...

    Cycle Analyst V3 preview and first beta release

    My 2 bikes with torque sensor + ca is running fine without any problems, one with version 3.14, the other with 3.15b. So it should be possible to address? Do you mind posting all your settings (just print screen from PC), maybe someone is able to help? Also, running the torque signal from the...

    My attempt at a lightweight EMTB with torque based PAS

    Nice! Looks like some interesting builds on that forum as well. Trying to make a user there to be able to search, but its not so easy with translator 😂Think I just need to wait for admin to let me in, now. On another note, I was out with the fatbike the other day when the rear hub started...
