Charging & Safety
Water does not stop a lithium metal fire, and standard ABC extinguishers fail to cool a runaway reaction. In this critical safety masterclass, we explain the difference between cooling and smothering, why Aqueous Vermiculite Dispersion (AVD) is the modern gold standard, and how to set up your workshop for rapid fire suppression.
Charging & Safety
Shipping lithium batteries is not like mailing a book; it is the legal transport of "Class 9 Dangerous Goods." In this regulatory deep dive, we unpack the eight rigorous tests of the UN38.3 standard, explain the 100Wh limit for air travel, and provide a professional protocol for packing and labeling high-energy DIY battery packs.
Charging & Safety
In the world of lead-acid batteries, a "Float" charge is life-saving. In the world of Lithium, it is a death sentence. In this electrochemistry deep dive, we explain why holding a lithium cell at peak voltage causes electrolyte oxidation and SEI growth, and how to program your solar controller or UPS to allow your batteries to "rest" for a 10-year lifespan.
Charging & Safety
Not all power supplies are chargers, and using the wrong one is a fast track to cell degradation or worse. In this engineering evaluation, we compare high-precision smart chargers like ISDT and iCharger against the bulletproof reliability of Meanwell industrial supplies, explaining when to prioritize active balancing and when to favor bulk charging.
Charging & Safety
That loud "POP" when you plug in your battery is not just a nuisance; it is a violent electrical event that pits your connectors and stresses your inverter's capacitors. In this engineering deep dive, we explain the physics of inrush current, how to calculate the perfect resistor value for your system voltage, and how to implement a pre-charge circuit to save your hardware.
Charging & Safety
If you are charging massive DIY battery packs, a standard Lipo bag is not enough to protect your home. In this comprehensive safety guide, we walk you through the engineering requirements for a lithium containment bunker, the physics of smoke filtration, and how to build a cinder block or steel station with automated emergency shutoffs.
Charging & Safety
When a pouch cell swells, it is a clear warning sign from the internal chemistry. In this forensic analysis, we explain the chemical breakdown of electrolytes that leads to gas generation, why you should never "pin-prick" a puffed cell, and the definitive safety protocol for the resistive discharge and disposal of damaged lithium batteries.
Charging & Safety
Leaving your batteries at 100% or 0% for months is the fastest way to kill them. In this masterclass, we explore the electrochemistry of "Dormant Stress," the 3.80V storage rule, and how to build a safe, temperature-controlled environment for long-term cell preservation.
Charging & Safety
We all want our batteries to charge instantly. But pushing current faster than the ions can move leads to the dreaded "Lithium Plating." In this materials science deep dive, we explain the concept of C-Rates, the impact of temperature on ion mobility, and why charging at 0.5C is the secret to a battery that lasts 10 years.
Charging & Safety
Charging a lithium battery is not like filling a gas tank; it is a delicate electrochemical dance. In this engineering guide, we demystify the Constant Current / Constant Voltage (CC/CV) algorithm, explain why the "Absorption" phase is critical for cell balancing, and show you how to program a lab power supply to charge any battery safely without causing an explosion.
