What's the maximum output voltage you've been able to achieve with this setup?
nerdling 6 months ago next
I've seen about 50 volts consistently with this setup. There is definitely potential for more.
bighacker27 6 months ago next
50 volts is a good start. Have you thought about connecting multiple units in series for a higher voltage?

How many cells did you use in total? Did you monitor each cell individually?

Thanks for the tips! I'll make sure to monitor cell temperature closely as I'm building my own DIY battery project.

How long have you been testing the battery so far? Is there any noticeable degradation?
johncarmac 6 months ago next
We've been testing it for about six months now and we've noticed little to no degradation. Very promising results!
hackerdad 6 months ago next
Six months of testing is quite impressive. Have you published any results or papers on this?

Absolutely! I'll be sure to include a cost breakdown in the full article I'm working on. This is just a sneak peek.

Is there a cost breakdown for this project? I'm curious to see how affordable it is compared to commercial lithium-ion batteries.
awaheed 6 months ago next
From my experience, DIY batteries can be as little as half the cost of commercial batteries. This project looks promising!

That's fantastic. I'm working on a budget for my own DIY battery project. Thanks for the info!

Has anyone tried to use this in a home energy storage system?
econstudent 6 months ago next
I'm currently working on a project for school that uses a similar setup for home storage. I will post updates when I have them!

What safety precautions did you take when working with the lithium-ion cells?
the_engineer 6 months ago next
Always use a glove with an insulating layer, work in a well-ventilated area and monitor cell temperature regularly. They can get very hot.

What software/hardware setup did you use to monitor cell temperature?

Even if this project is only covering DIY batteries, cell balancing is crucial. What setup did you use for this?
inquisitive_coder 6 months ago next
I balanced the cells manually when building the battery pack and then set up a passive balancing system during use.
anothernerd 6 months ago next
Passive balancing is an interesting choice. I'm assuming you're aiming for simplicity over performance, correct?
coding_enthusiast 6 months ago next
I've seen a few setups online that use active cell balancing. Have you considered making that upgrade in the future?
techspert 6 months ago next
We haven

What was the inspiration for this project? Are there any specific use cases you had in mind when designing it?
photon_geek 6 months ago next
Our main goal was to create a cost-effective and reliable solution for home power storage. Commercial batteries tend to be expensive.
codemaverick 6 months ago next
Absolutely! Considering the testing and results we've had, our next step is definitely to implement active cell balancing.
