#li-ion — Public Fediverse posts

For when I'm working on something containing an energetic battery.

(Inspired by Big Clive, obviously)

Oh, also, the old spicy pillows.

I'll have some fun passivating them outside when I have a chance.

I replaced the battery pack in a Mac laptop a few days ago. The replacement I ordered came with a tiny little booklet labelled "Instructions", but it consisted of nothing but warnings.

One of them literally says "Do not hammer a nail through the battery."

Aw, that was my first impulse...

#warning #ObviousWarning #obvious #LiIon #exciting

Heard about #DonutLab yet? Me neither.

However, they released an amazing new #DonutMotor 2025 in multiple products and now they're releasing a new kind of #solidstatebattery #DonutBattery that may disrupt the whole market according to their promo video: https://www.youtube.com/watch?v=Y-aPS2AwMbc

- cheaper than #LiIon
- 50% weight or +100% capacity for same weight
- full charge in 5min
- no loss due to temperature
- more cycles than you will ever need
- no degradation over time due to fast #charging
- no problematic materials
- ...

You "donut believe"? Well, they want to prove their point soon: https://www.youtube.com/watch?v=uiOma6v_EZY

Now, they have my attention. 🍿

I've been designing PCBs for a while, but this is my first time ever designing one with any sort of battery charging or antenna connection. I hope I managed to do a decent job, but if anyone has more experience with either and feels like taking a look at my PCB/schematic, it would be greatly appreciated!

Защищенные li-ion аккумуляторы 18650 своими руками — добавляем плату защиты

Как из незащищенного li-ion аккумулятора сделать 18650 protected. Добавляем плату защиты сами. Небольшой гайд по этому процессу. А также разберем, как влияет плата защиты на характеристики аккумулятора.

Защищенные и незащищенные LI-ION аккумуляторы

Что такое защищенные (protected) li-ion аккумуляторы? От чего они защищают, как они устроены, и когда их нужно использовать? И так ли беззащитны обычные незащищенные аккумуляторы? В общем, подробно о li-ion 18650 и 21700 PROTECTED .

"Lithium-Ion Batteries: WHY They Demand Respect" by @hackaday - Conference badges switching up from AA to 18650 cell batteries creates too many chances for people to disregard instructions, like "playing with fire at someone else's house". https://hackaday.com/2025/11/04/lithium-ion-batteries-why-they-demand-respect/ #LiIon #batteries #safety #energy #electronics #Maker #tech

@GamesMissed

People recommending you manually use a CC/CV power supply are not helping you 😉

Good chargers will let you set what *type* of battery it is, and will correctly charge all major types. I've got a four-cell (four independent charging circuits) that will happily charge NiCad, Nickel Metal Hydride, LiFePO4, Lithium-ion polymer, and a few others. It mostly autodetects the correct type.

They're not stupidly expensive. The model I have is currently $37 Canadian from Amazon:

Can anyone please give me advice on finding a reputable seller of Li-ion batteries in the UK?

I want to replace the battery in a solar floodlight. It uses 4 ICR18650 cells at 7.4Vdc, and I'd rather buy a pre-balanced battery pack because I haven't worked with Li-ion before.

Непросто было найти крону аккумулятор не на литии.

Не, я понимаю, что ёмкость больше. Я даже понимаю, что кому-то зарядка батареек через type-C может казаться удобной.

Но в гитару такие батарейки ставить банально нельзя - их преобразователи шумят.

#hardware #log #batteries #rechargable #LiIon #NiMH #guitar #sound #audio #tech

Thought I'd try some of these. If you're not familiar, they're a Li-Ion battery dressed up as AA with an internal PCB that regulates charging and bucks them to 1.5V. Good for devices that aren't happy with the 1.2V of a NiMH AA rechargeable.

The capacity is bullshit, as usual when you buy from China, real one is maybe half that, but that would've been ok.

Not okay: Overheating to the point where the battery compartment is deformed and the device fried*. At least they didn't catch fire. 👎

Can't recommend at all.

* Probably. Can't test it with other batteries because they no longer fit in the deformed housing.

A really important piece by our friends @theverge.

Battery Quality really does depend on who makes the cells - and how.

Как продлить жизнь литий-ионному аккумулятору: актуальные правила на 2025 год

За последние 15 лет литий-ионные аккумуляторы заметно эволюционировали. Появились новые химические составы (LFP, NMC), а классические на основе LiCoO₂ отошли на второй план. Системы управления (BMS/Battery Management System) стали сложнее, удельная энергоемкость элементов постепенно выросла... Однако фундаментальные законы их старения никуда не делись, а наши привычки лишь адаптировались под новые реалии. Давайте разберемся, как продлить жизнь аккумулятору вашего смартфона, ноутбука или электромобиля сегодня, опираясь на современные данные.

My #BMS #PCBs arrived from @aislerhq and they look nice. I designed it because I couldn't find 3S BMS for #LiFePO4 cells and didn't like the voltage thresholds of the cheap #LiIon ones.
It uses the #BQ77915 chip from #TexasInstruments. Size is 63x50mm.
While fetching all components according to the BOM, I noticed the #diode had the #footprint SOT-323 assigned. I only have SOT-23 ones :blobcatgoogly:
I'm glad that I can still make it fit, and the third leg isn't used at all (it's a single diode).
Can't wait to find some time to finish soldering a few and try them out.
It supports 3S up to 5S, and I added #silkscreen part to mark how it's configured.
The back has detailed instructions, so I don't forget them.

A #rnode build for #reticulum using a #raspberrypi5 and #geekwormx1206 #ups for a #carnode or #solarnode
https://www.loramesh.org/subpages/upsrnode/upsrnode.html
Running #meshchat , four #liion #21700 5000 mAh batteries seem to run the #rak4631 and Pi for at least 24 hours. The device can be re-charged using #usbc or 9 to 18 V DC at up to 3 A via a jack or other connector. The rnode shuts down cleanly when batteries run out & re-starts when power is back, whereupon the batteries charge at the same time in #passthroughcharging

@erebion I will. I'm carrying it right now. During the test, the screen is fixed with some tape.

Thanks for asking regarding the battery connector 😄 I was very careful and used kapton tape to isolate all contacts I wasn't working on. I think that working on the old (swollen) battery is less critical than working on the the new battery. I wasn't able to measure a voltage on the old battery. Both batteries are equipped with a protection circuit.

Китайские ученые предложили метод восстановления Li-Ion батарей. Спасение от электронного мусора уже близко?

Исследователи из Фуданьского университета в Китае разработали метод восстановления литиевых батарей. Возможно, эта технология позволит сократить количество электронных отходов и одновременно снизить расходы на закупку аккумуляторов для бизнеса. Основы нового метода изложены статье на Nature — об этом сегодня и поговорим.
