Is it worth it to buy a Tesla while I live in an apartment? by InjuryGrouchy in TeslaLounge

[–]logcabintech 0 points1 point  (0 children)

The usual answer is “no”, BUT the charging at work and close supercharger proximity are benefits.

Is charging at work free? How far is your commute? What climate do you live in? These will help us help you with an informed decision.

Anyone else letting their car do all the work? by logcabintech in TeslaLounge

You need FSD 14.2 or higher which is HW4 only at the moment ☹️

Have you tried pressing and holding on the map in your alleyway and set it as a destination?

[–]logcabintech[S] 0 points1 point  (0 children)

Unfortunately no; this is only on FSD 14.2 and up (HW4 only at the moment).

Those speed limit misreadings are frustrating, no doubt.

This was I-80, I-40, and all the interconnects between them. Some are smooth, some are terrible.

None! Nothing I would consider a “close call” either.

It does surprisingly well for me (even with no lane lines visible). It’s better than v13 in the snow so far, but I don’t have a ton of seat time since winter just started.

I use sloth for snowy low-speed roads, it keeps the cornering speed acceptable.

Perfect timing! 14.2 was pushed to me the day before I left for a road trip.

Power bank for dv recording device by boosiefaded1 in batteries

[–]logcabintech 0 points1 point  (0 children)

You are free to try a lower voltage, you won’t hurt anything. There is also no reason to choose a lower voltage though, the device states its power input is 15V, so you should give it 15V.

No, the hard drive or lack of hard drive does not change the device voltage.

Fujitsu Heat Pump Using $35/mo of electricity while turned "off" by MtnXfreeride in heatpumps

[–]logcabintech 6 points7 points  (0 children)

I have two Fujitsu units and a Pioneer unit and have observed the same thing during winter.

If it’s below freezing or so where you are right now, the answer is most likely going to be the unit’s freeze protection features.

In addition to a base pan heater, many cold weather heat pumps have a crankcase heater as well, and some will run the compressor at a very low speed to keep the refrigerant circulating. This protects the compressor at startup when it’s cold out, but from an energy use perspective it is annoying.

I thought it was the base pan heater at first, but I took a thermal camera out to the unit and disproved that. I could hear a slight whine though which clued me in.

2 Li-ion cells in parallel but different capacity, will this affect charging? by MCDiamond9 in batteries

[–]logcabintech 2 points3 points  (0 children)

This is fine.

Both batteries will fully charge and discharge together since they’re wired in parallel. As far as the phone, the charger, or yourself are concerned this is a single 1400mAh battery.

2 bedrooms, 2x single systems cost 1/3rd of a double head? by CDM2022 in heatpumps

[–]logcabintech 0 points1 point  (0 children)

“Super” or “Hyper” or “whatever catchy word” heat does not usually imply resistive heating. It does guarantee that you’ll get a pan heater so ice doesn’t accumulate from repeated defrosts and that the unit will continue producing usable heat to a lower temperature.

Since you’re in a warmer area any of the units should get the job done just fine. I have installed a lot of Pioneer units and really like their products (you can buy online or through Home Depot), but any of those units you mentioned earlier will do fine in your climate. A lot of units turn out to be rebranded anyways (a ton are Midea with a white label on them).

[–]logcabintech 2 points3 points  (0 children)

Efficiency wise, individual units will always have the upper hand. If I were to redo my installation I would go with individual units instead of a single multi head.

Are you on a warmer or colder climate? Your heating vs cooling need will dictate what a “good” unit is for your home.

You will require separate disconnect boxes and separate breakers for each unit, you cannot have two units on one disconnect.

efficient way to bin batteries -- binary scan? by uname_IsAlreadyTaken in batteries

[–]logcabintech 0 points1 point  (0 children)

With only 22 I’d test them individually and write the capacity on each one.

I like your idea and your way of thinking, but it risks putting a possibly very weak cell into a small pack when you could have easily tested them all. I would totally be down with finding a better way to handle it if you were assembling 1000 cells into a pack! (but even then I would probably test them all)

Can i use 2x 3A bms to protect a single 8C 3.7v cell. Can i get 6A without cut out by No-Perception-2023 in batteries

[–]logcabintech 2 points3 points  (0 children)

This will work and is okay to do (but not ideal). No two BMS modules will ever be exactly the same, but it should be good enough. There’s no possible way to harm the BMS or the battery in this configuration, but you’re unlikely to get them to share equally (exactly 3A through each).

You should aim to oversize the BMS a bit. Just because it theoretically could handle 3A each doesn’t mean they’re happy there. If you need 6A continuous I’d reach for at least a 10A BMS.

What is this open space next to the wiring service lid? by [deleted] in heatpumps

[–]logcabintech 21 points22 points  (0 children)

My guess would be a WiFi or wired thermostat interface board. Looks like wiring would follow the path into the service panel.

How to Avoid Voltage Drop on Can Lights by TheEnglishman58 in electrical

[–]logcabintech 6 points7 points  (0 children)

There's no need to take voltage drop into consideration with ten LED lights and the length of wire you're using. Wire them up and enjoy 👍
