Hmmm my ding ding dong!

Daring today, aren’t we?

Indeed.

The idea of the battery pack is to provide energy for a household. The reason I’m considering such a large amount in series is that it would make an inverter much more efficient and easy to make. An EGS002 based circuit for example relies on a 400V DC, which I find very difficult to make out of lower voltages. Especially when high wattages are involved. There are no DC-DC converters commercially available with around 55V input (16s li-ion) and 400V output at 4KW. There are however commercial inverters available such as the Victron Multiplus II 48V that can deliver about 4000W of AC. This would suit my needs however I want to DIY as much as possible. I also have plans for a self made solar charge controller and possibly even a wind controller as extra modules next to the battery charging circuit and inverter.

Solving the issue of converting high power 55V to 400V DC would remove the need for a high-series battery pack as well.

Indeed blindly dumping the charge into a battery is not the intention. There will be additional circuitry to prevent cells from overheating and to limit the inrush current that they receive but the general idea is a capacitor that floats between 4.2V and Vcell.

Not only that, if I’m that crucial to a company my salary should get another zero.

A French person? Protesting? No way!

It’s a Mass Relay from the Mass Effect games.They’re really good games and often sell for cheap on steam.

Quack.

How do you make a Welsh man fall asleep?

Ask him to count how many bedpartners he had.

Have you considered lasercutting or CNC milling as well? And what about lithophanes?

3D printers are highly accessible to people, even people with no technical knowledge can just buy one, download models and have it print successfully. Selling 3D printed parts pretty much only works if you do design as well and not many people request something like that. I don’t think you can make a feasible business out of 3D printing alone.

And there is mechanical design and aesthetic design, which both are completely different practices. I mean things like making a TV mount or a tube holder vs making a detailed Warhammer 40K model. You need different software and skills for both of them and it consumes a lot of time to do well.

CNC milling and lasercutting is not as wide spread as 3D printing is so you could still end up finding people interested in objects made this way.

Howtobasic intensifies.

Kept ya waiting huh?

Because I have a metric shitload of them available. Indeed if i was going to order fresh cells 21700 is better especially for a home battery system.

The plan is to have it function as a home battery, connected to either a solar panel or a small balcony wind turbine. I also want to charge it when the electricity cost is low and discharge when the electricity cost is high on average.

Another part of the project is to build a grid-tied inverter.

Ooh, a deshittified version of imgur? Or did you invent time travel?

Thanks! There’s about 3mm space in between the batteries so air would easily flow through. I’m not sure if that is preferable though, ideally the cells do not get warm at all.

Yeah. I see what you mean. I find it acceptable for certain use cases like a quick showcase for stuff I want to share freely anyway.

It’s a bad habit.

I think a dual nozzle system is already good enough for most users. Especially when your print area is large enough to make it feasible.

WAF had me laugh out loud.
