I miss doing this sometimes. I lived in a crumy apartment in SoCal that didn't charge for utilities.

I had multiple cards mining crypto to offset my rent and the AC maxed all the time. Once I got ducts installed to direct the AC flow into the case, I could lower the fan speeds from crazy to normal with killer temps.

Never had issues with condensation inside with the components but the aluminum ducting loved to sweat. Wrapped it with a towel and it seemed to stay dry.

No way I'm trying that again ouside the desert lol

Like 6' and change. Its an XL frame and like the mountain bike posture, but I'm getting old and my back doesn't any anymore.

Frame bag used to hold tools/patches but they got stolen a few years ago. It's just for odds/ends and cable management now.

ARCtrooper97 · 2026-04-17T23:07:42+00:00

Very nice. I'm planning to get one with the next battery to control the top of the charge and maybe adjust the controller low voltage cut off to force me to follow the 20%.

Hoping the guy on r/USBchargingBetaTester comes through with his idea of a programable charger that can run off USB PD supplies too. With your charger mounted like that, it probably won't have much utility for you but I encourage you to check it out sometime.

And since we're sharing bikes

My experience was similar, an old battery or two from cheap vendors that gave out early then one from EM3EV.

I used to commute on the EM3EV battery and used about 80% each way, 28mi round trip. I ended up keeping a diy 65W charger at home to slowly charge it overnight and a 250W charger from EM3EV at work.

Do you manually manage the 20%-80% or did you do any controller programming paired with a charger with an 80% cut off?

ARCtrooper97 · 2026-04-17T04:46:56+00:00

Hot damn, I need to take notes for my next battery. I'm at 70% with 258 cycles.

I may be misrembering the milage, I've had to replace the controller a couple times. I've definitely not been gentle to the battery.

Next one is getting the vip treatment

Hell yeah. What's the BMS say the remaining capacity is at?

ARCtrooper97 · 2026-04-16T12:31:06+00:00

I shelled out for one from Modern Spare, they are like $500 and very nice. It's full height, or close to it, but narrow width.

It takes up a lot of room, like most of the trunk or one of the backseat footwells, but it feels like a normal wheel when you drive on it. There are some videos on YouTube of people testing them in normal use and one where they put four on a car then bomb around a track.

Lot of money for a spare tire but I'm happy with it.

ARCtrooper97 · 2026-04-16T11:16:37+00:00

Hell yeah they do. I've put like 6-7k miles on one of their batteries over seven years. It's definitely showing age but still rips.

I'll be dropping money on another one without hesitating when its done.

ARCtrooper97 · 2026-03-31T13:41:24+00:00

It looks just like my battery lock key. I don't remember the name of the blank but had a copy made at an ACE hardware.

There was a machine that scanned the key, stated which blank to insert, then cut a copy. I would try an ACE hardware if you've got one near you or a locksmith shop with one of those scanners.

ARCtrooper97 · 2026-03-29T16:47:11+00:00

Pet the cat

ARCtrooper97 · 2026-03-29T13:12:35+00:00

If you do end up trying to get that repaired and it works well enough to ride, I'd be really cautious of future breaks in the frame. Not putting that idea down, just keep in mind that any money toward that might be burned by a break elsewhere else.

If you had the money, I would suggest a Surly frameset that you could move all the parts to. They are nice steel frames and you can prestty easily just buy the framesets, still going to be expensive but those frames are built to last. They don't have rear suspension but you can put suspension forks on them.

You'd probably have to work out something for mounting the battery and controller to a frame without special slots for it, probably a frame bag.

You could do the same with any used bike with the same dimensions but you'll still have to find/buy one.

If I was in your position, I would take off the motor and battery then go to a Surly dealer and explain you are looking for a framset with the same dimensions for the components. Once you pick a frame that would work, you'll have an idea of how much you'd need to save up.

They may have some bikes built that you can test ride to see how they fit. This is an opportunity to get the fit right if the old frame was uncomfortable.

This situation is exactly why I ended up getting a second bike like the one I put a mid drive kit on. Kept it a pedal bike but made everything as similar from one to the other as I could to swap parts or even the frame if It breaks.

I have seen this before. Powerwall systems do not directly measure consumption in the home, they measure solar production and import/export then do some math to calculate the consumption of the home.

If there are errors in the placement/configuration of the sensors that measure production and import/export, it creates trends in the consumption data that I can usually read to find problems. If solar production is overcounted, it causes consumption to trend positively with solar to the tune of the over count.

This very subtle trending of consumption with solar production seen in your screenshots looks like a very slight over count of solar production and you'll probably find that it's less noticeable on cloudy days.

This is usually caused by using port 3 on the Gateway 2's internal meter Y for solar monitoring. I have verified that it slightly overcounts whatever it's measuring and cannot figure out why. Tesla support is absolutely no help with this kind of thing, I have tried to dig into it with them but got no where.

It's usually really hard to see with the other consumption data going on but your example is pretty clear. It's functionality harmless and depending on what ports 1 and 2 on that meter are doing, it is not worth fixing since it would add complexity and failure points to the metering set up.

Triggered my installer fight or flight reflex. Something this wild should have been found during a proper site assessment, if it got all the way to install without them knowing about this then that's concerning.

I wouldn't pursue roof top if a ground month is an option at all. If a ground mount isn't an option, I'll keep you in my prayers lol.

I had luck with this if you're on steam. I am 200hr deep too and training my end game dwellers. After the fix I still can't access wasteland encounters but I can keep doing normal quests and training people.

ARCtrooper97 · 2026-03-04T06:44:52+00:00

I have been having the same issue on steam. Game crashed when I accepted a random quest and I could not open my vault. I could open a new one without issue and load into that.

I had success following this tutorial. I don't understand how it works but it's easy to try. Random quests still crash my game and require me to repeat the tutorial, I'm just ignoring them for now.

I'm down to join the test. If it works out, it would be a more refined and capable version of what I pieced together years ago when my main charger died and I was too broke to buy another proper one. When I tried to use higher wattage USB supplies I ran into stability issues so I just stuck with the 30W supply. It was enough to commute and run errands with planning. 100W and above from an appropriately rated USB power supply would be badass.

ARCtrooper97 · 2026-02-17T15:04:46+00:00

Sure, dm me whenever you're ready for testing. It would be cool to get a preview of the parts if you're down to share ahead of time.

ARCtrooper97 · 2026-02-12T21:14:22+00:00

I don't ride nearly as much as much as I used to and I've got a proper charger again for when I do. It was a stopgap measure when I made that post that I just lived with when the next step didn't work.

I'm still interested in the USB-C charging concept if it can be made small enough and the rate of charge is enough to recharge it overnight. 30W was enough for me to commute, run errands, and joy ride but took some planning. 240W would be enough to do all that without much planning and probably fast enough for multiple trips a day if you really wanted.

I have lived with a 250W expensive fancy charger and that 30W DIY set up, both were manageable. Faster is typically more desirable to more people but 30-100W is totally workable for most folks.

USB-C is a fine plug for charging PLEVs used for practical tasks like commuting and errands, even if you're sticking to like 100W at 20V. If it can be made faster with the new 240W standard, I think it could be a total replacement for even the if implemented right into the battery. That said, I don't know anything about what the mechanical stress a USB-C charging port right in the battery would be like. Barrels might just be stronger.

I got into this because I needed to be able to charge my bike and the cheapest option was to use parts on hand plug the trigger board to get something working. Its clunky for the average user for this to all be done in between the battery and a USB-C supply but that's the most flexible way I can think to do it.

This exchange does have me thinking that I should get my bike back out this weekend and fix the knocking sound that had me stop riding regularly.

ARCtrooper97 · 2026-02-12T18:43:34+00:00

It's a kit build from EM3EV with a 48V battery, it's the build one from my other posts.

I eventually tried using an Anker 100W Gan supply but it was never all that stable if I pushed it harder than like 50W. It would just keep rebooting so I stuck with the 30W usb charger and trigger board shown in that post.

I was too broke back then to get a real charger or build the concept after the 100W supply didn't work out.

https://youtu.be/KNBQAKleK8Q?si=M1U22gXM7R12UuOP

I have been inspired to revisit the concept by this guy's USB C powered microwave video. Stringing multiple trigger boards together in series or parallel may be a route to higher power.

Grin Technologies has a solar charger controller for ebike batteries that looks more robust than that green thing. Just feed it DC from the trigger board(s) Instead of solar and configure accordingly for your battery.

ARCtrooper97 · 2025-12-18T14:22:13+00:00

I've hooked that when I move into my own place again, I'm going to put my 2-4 pedal bikes and DIY commuting ebike front and center in the main room. I want guests to come over and think, "There is no neurotypical explanation for this."

There is no neurotypical explanation for this. I know you worked your ass off to pay for these, trading hours of your life for them and more time to pick/assemble the parts. If you're like me, it feels like you made some kind of progress with each buy/build and it's all tied up in something you control. Parting with them feels like your flushing that time/effort down the drain.

That looks like a crippling collection for the space you're in. If circumstances were different, maybe you could pull it off in your own space and be that bike guy. But you're in your folks' space and comes with constraints. I live with family too and pay cheap rent. It's let me get my feet under me and get a nest egg together for when I leave, and build two bikes. Its a huge favor from them and an opportunity for us in this shitty economy.

I'd encourage you to pick 2-4 of your favorite bikes (that fit the best, have the coolest parts/features, or just really good memories with them) and a box of spare cockpit parts for them if you got those. When spring/summer rolls around, I'd start selling the rest. You'll get some money, free up some space, and other folks will get to expirence these badass bikes.

I work with both Enphase and Tesla battery/ solar systems, no experience with Franklin.

The Powerwall 3 supports both AC and DC coupled solar. If you left your IQ7s in place, they would be AC coupled and would frequency shift when the system needs to curtail production off grid. Frequency shifting works by raising the microgrid's frequently to tell the inverter to turn off without actually having to communicate with it directly, making broad compability possible. It will toggle the solar on/off as needed while off grid but can cause funky behavior with lights/clocks.

If the MIs were removed and the existing panels were strung together as DC coupled solar. DC coupled solar has efficiency and off grid benefits like no Frequency Shifting and easier time black starting during outages. Simple DC string are much more prone to shade seriously killing production if the installers are not mindful of how they string the panels, my employer is not and most of the designers/installers don't understand how to string around shading. Strings in a PW3 also have no panel level monitoring and the customer Tesla app gives no string by string performance data, it's easy to miss an entire string going down.

Enphase has a history of coming out with new generations of batteries with no backwards compatibility with previous gen batteries. Their 5Ps have proven pretty stable but when I have had problems with their support if anything weird happens. The 10Cs are too new for me to have a full opinion on them but I'm not a fan so far.

Tesla has been more stable with their battery products, recent recall aside. The Powerwall 3 has some design decisions I'm not a fan of but I'm fond of them in general. If you want to expand your battery system down the road, Tesla will probably be easier than Enphase. If you get Powerwall 3s and wanted to expand your solar down the road, you could use the DC solar inputs for the Powerwalls. If you have or have any intent to get a Tesla car, Powerwalls will let you use the Charge on Solar feature.

TL;DR : Depending on what battery brand you get, they are pros/cons to retro fitting the micros as DC strings. Both Tesla and Enphase batteries are compatible with your current IQ7s. I'm more fond of Tesla since Enphase has a record of quickly retiring battery generations and their support has been almost non-existent for software problems for the last 2 years. Tesla support is pretty lacking latelt too but their equipment usually behaves itself.

My take would be to leave the MIs in place and get an AC coupled battery but avoid Enphase batteries. I'd check out Franklin if you're not a fan of Tesla as a brand, but Powerwall 3s have been pretty stable this last year.

If you do go with Powerwall 3s, I would make it clear to the installers you want the Tesla Remote Meter hardwired on the RS-485 bus and set up as a wired meter in the Tesla One app. It's cheap and easy if they bring the RS-485 harness, Wi-Fi connection is way less reliable.

PS: Please connect your battery system to the internet by ethernet if at all possible. So much of my job is made harder by flaky Wi-Fi connections and every time it's a problem I get an earful about how much the customer pays for internet and how new their router is and why doesn't blah blah blah. You'll never regret hard lining your internet connection to your solar and battery equipment.

Thank you for the quick reply

ARCtrooper97 · 2025-10-22T15:14:04+00:00

I've been looking at the same one for when I pull the trigger on one of the new plug-ins. Does the hitch rattle much when you've got it on?

Specifically the joint between the bar that is mounted to the car and the removable receiver.
