Design something that will unlock a bms. Many models lock with good crlls but hit zero. I have 10 brand new Powersonic lifep04 lithium 12v batteries. Over 5k, sat never used and bms locked due to cells being zero.

🚀 Introducing COMET Air Mouse 🖱️ I’ve been working on a compact wireless air mouse built around the ESP32-C3 + MPU6050. Instead of moving a traditional mouse across a desk, COMET converts hand movements into real-time Bluetooth HID mouse controls. 🔹 ESP32-C3 🔹 MPU6050 gyroscope 🔹 BLE HID 🔹 Motion-controlled cursor 🔹 Left / right click 🔹 Gesture-based scrolling 🔹 Adjustable sensitivity & smoothing 🔹 Battery-powered design The firmware is now packaged as a ready-to-flash .bin release, making it possible to deploy the device without setting up the Arduino IDE or installing the required libraries. This project has been a great hands-on experience in embedded systems, Bluetooth HID, sensor processing, firmware development, and power management. And this is just V1.0. 🚀 🔥 Top 6 ESP32 eBooks #COMET #AirMouse #ESP32 #ESP32C3 #MPU6050 #Bluetooth #BLE #EmbeddedSystems #IoT #Electronics #Hardware #Arduino #Engineering #Maker

I’m planning a long article about the baghdad battery. But first things first: let me see it working! I don’t care “expert opinion”, facts are facts. So I set up this “baghdad battery” in a rush, as a proof of concept, and TÁDÁMMM! it works. Even this rudimentary setup can produce 0.44 Volts. Copper + iron + orange 🍊 juice. (Which is not really surprising if someone knows the physics behind… it should have 0.78 Volts instead khm.) This is just one battery cell. You can connect them serially to have higher voltage or parallel to reach higher current. This is it for today. I have a lot of 🗿s to cast instead of this stupid battery 🔋

We're working on a brand new Xiaomi SU7 Ultra at EV Clinic in Belgrade that was damaged during transport from China. The low-voltage battery was completely depleted and damaged during recovery attempts. We've connected directly to the CAN bus to diagnose the issue and discovered that the BMS high-voltage interlock software system is latched, preventing us from re-enabling the vehicle. We've repaired the 12V lithium battery, but we need the original diagnostic tool to reset the BMS and resolve this software interlock that's protecting the high-voltage battery. Stay tuned…

🔋 Can a 7 mm Dent Really Cost You Your EV Battery Warranty? A customer reportedly lost the battery warranty on a Tata Tiago EV because the dent/scratch on the battery pack measured 7 millimetres (mm), while the warranty reportedly covered damage only up to 5 millimetres (mm). What kind of warranty is this? How many EV owners are actually aware of such conditions, and is this policy the same across all EV brands? #EV #India #TataTiagoEV #BatteryWarranty #ElectricCars

On June 26, an all-hands fire broke out inside a basement apartment in a private dwelling in Queens. FDNY Fire Marshals determined the cause of the fire to be a lithium-ion battery that was charging in the kitchen of the fire apartment. The fire trapped a 48-year-old man inside the home, who had to escape through a bedroom window. The victim later died at a hospital. This is the first death in 2026 connected to a lithium-ion battery fire that happened this year. Where possible, charge and store lithium-ion batteries or micromobility devices OUTSIDE. Do not charge them overnight, and do not block any exits. It can mean the difference between life and death.

A Hybrid is the Worst of all Worlds 11,000 Euros extra costs after 100k km driven. "Again, the "worst of both worlds" applies to the 2018 BMW G30 eDrive Hybrid, whose complete battery pack is so worn out that repair isn't feasible without replacing all modules. This vehicle has only covered 150,000 km, yet it requires a new 9 kWh battery pack costing €11,000. Despite active thermal control, the cells have degraded and inflated under high current rates, where a small battery supports a large powertrain. Each kilometer driven in EV mode damages the battery pack four times faster than the larger battery packs found in full EVs. Hybrids are truly unsustainable and cannot be a part of any eMobility narratives. So, in addition to the pollution from the fossil engine, oil changes, and other maintenance, you also have waste production from poorly designed weak battery systems." Credit: EV Clinic

THE 100-YEAR BATTERY THEY WON’T SELL YOU Edison invented the nickel iron battery. It can last a century. Too durable to profit from, so instead you get batteries that die in five years. Lead acid is cheap and fine for cars. Lithium ion is light and great for electronics. Lithium phosphate is tough but pricey. Nickel iron beats them all in lifespan, but it’s heavy and bulky. Perfect for powering a house, terrible for a car. Source: nathandickeson

We were first in world for 1 cells swap…but… Is it possible to repair any high-voltage battery (HVB)? In reality—no, not always. The end-of-life for an HVB depends heavily on mileage, aging, cell type, C-rate, and the overall design and lifespan expectations. Repairability varies significantly depending on whether the pack uses pouch, prismatic, blade, or cylindrical cells—and whether the failure occurs early or late in its life. If the battery fails early in its lifecycle, repairs are usually feasible. However, if it fails after reaching its intended lifespan, any repair tends to be more of a temporary “patch” until a replacement pack is sourced. From experience for cellswap: •Blade and some pouch cells are nearly impossible to repair. •Prismatic cells are difficult. •Cylindrical cells are the easiest to repair—depending on the pack design. (* module change not a topic) This is why it’s encouraging that BMW, Hyundai, Mercedes, and Porsche have finally begun adopting cylindrical cell designs, moving away from less reliable pouch cells—albeit a decade too late. For example, a Tesla Model S 100D battery can last up to 600,000km in Model S and 450,000km in Model X. The older 85 kWh pack in the S85 can even reach 600,000 km. However, the same pack in the high-performance P85D tends to degrade around 400,000 km, requiring full replacement due to total deterioration. In summary: Yes, battery repair is possible—but only if the pack is still within its designed service life.

$NXXT gets the tech from MIT Labs to bring it to the Grid Battery innovation doesn’t start on social media — it starts in research labs. The Massachusetts Institute of Technology (MIT) has been responsible for major breakthroughs in battery materials and energy storage science. That research was licensed and commercialized by A123 Systems, a company built to turn advanced lithium-ion chemistry into industrial-grade systems. Now NextNRG ($NXXT) is entering a relationship with A123 to advance U.S.-manufactured battery energy storage projects. This is a clear lab-to-grid pathway: MIT science, A123 manufacturing, and NXXT deployment into real infrastructure.

Guys, you won’t believe what happened to my brother yesterday. 😭 He got home around 11 p.m., parked his car outside and went to sleep. The next morning, he came out to use the car and noticed the bonnet was open. He opened it and… his battery was gone! 😭💔 He called his mechanic and told him he was scared to buy another battery because the thieves might come back. Later that evening, they went to a battery shop to get a replacement. The first shop was closed, so they entered another one. Guys… guess what my brother saw on the floor? HIS OWN BATTERY! 😭😭 He had written his name on the battery because it was brand new, so there was no mistake. They asked the person who brought it, and he claimed he bought it from someone else. They called that person… And it was the actual thief! The most shocking part? The thief was just a 13–14-year-old boy. 😭 He even demonstrated exactly how he opened the bonnet and removed the battery. That’s the video you’re seeing here. And guess how much he sold a ₦120,000 battery for? ₦15,000! 😭💔 Imagine waking up to discover your battery is gone, then finding your own battery in a shop the next evening. 😂😭 This country sha… you really have to watch everything. Car owners, please secure your cars properly. And parents, we really need to pay attention to what these young boys are getting involved in. Have you ever experienced something like this before?

So far this year, 18 people have been killed by fires caused by lithium-ion batteries. These fires are dangerous and fast-moving. Just last month, the Fire Safety Research Institute produced a powerful video demonstrating why it is so difficult to escape from a fire started by a lithium-ion battery.

What can GrokPod do that Meta Muse Charm can’t? Play my LIVE video from X! Sure it’s a tiny screen, but you can switch off the video and save battery and listen to the radio feed! All done by voice via the amazing Grok Grok Bot! In fact I have full X access via GrokPod and posted this from it. We build better in a garage!

People always love to ask, "What are you going to do when the battery goes on your Tesla?" This 2019 Model 3 RWD owned by Eric @ Drive Protected ™ still had the ORIGINAL battery and rear motor after 381,000 miles (613,000 km). Even after all those miles, the battery retained 70% capacity. He decided to bring new life to the car by swapping the original NCA pack for a modern LFP pack from a newer Model 3. The original pack was still perfectly functional, the swap was just for performance. Swapping a battery in a Tesla is much quicker than people think. In just a few hours, the orginal battery was removed then replaced with a LFP pack. Once configured via the computer, the car is perfectly functional. There’s no huge mess, not a lot of wires, it’s actually very simple once you are experienced with it. His Model 3 now functions and charges like a newer car. Tesla vehicles are designed from the ground up to be very serviceable.
