Molten nickel is 1400°C. Hydrofluoric acid gas is invisible. A 48V short circuit is blinding. In this safety masterclass, we detail the mandatory Personal Protective Equipment (PPE) for battery work, explaining why standard leather gloves fail against high voltage and why you need polycarbonate eye protection to survive a blowout.
Tools & Equipment
Processing recycled cells isn't just about charging them; it's a data management challenge. In this engineering guide, we compare the hobbyist Opus BT-C3100 against the industrial MegaCellMonitor, establish a rigorous "Binning Protocol" for capacity matching, and explain why the "Self-Discharge Wait Period" is the most critical step in building a safe Powerwall.
Tools & Equipment
A loose crimp is a fire starter. In this mechanical engineering guide, we explain why hammer crimpers fail, why you need a 10-ton hydraulic tool for 4/0 cable, and the metallurgy of "Cold Welding" copper lugs to create a connection that is immune to oxidation and vibration.
Tools & Equipment
A standard charger is a one-trick pony. To build custom packs, revive dead cells, and perform top balancing, you need a variable power supply. In this engineering review, we explore the Riden RD6006/RD6018 series, explain how to build a 1000W charging station from old server parts, and detail the critical safety diodes required to prevent your battery from blowing up your bench equipment.
Tools & Equipment
A $10 hardware store multimeter is a danger to your pack and your health. In this engineering guide, we explain the difference between accuracy and precision, why LiFePO4 chemistry requires 4.5-digit resolution, and why CAT ratings are the only thing standing between you and an arc-flash explosion.
Tools & Equipment
A high-resistance connection is invisible to the eye but glows like a star to a thermal camera. In this diagnostic masterclass, we explain the physics of IR imaging, how to perform a dynamic load test to spot weak spot welds, and why a $200 thermal module is the best safety investment for any battery workshop.
Tools & Equipment
Soldering onto a battery pack is a race against time. If you take longer than 2 seconds, you risk melting safety seals. In this guide, we evaluate the thermal recovery of T12, Hakko, and JBC systems, explain why 100W is the minimum for BMS work, and provide the definitive technique for soldering 10AWG wire without cooking your cells.
Tools & Equipment
A multimeter measures voltage, but it cannot see the health of the chemistry. In this engineering deep dive, we explain the physics of 1kHz AC internal resistance measurement, why the YR1035+ is mandatory for cell binning, and how to interpret milliohm readings to catch failing cells before they enter a pack.
Tools & Equipment
The label on a lithium cell is often a work of fiction. To build a balanced pack, you must measure the actual energy output. In this technical guide, we review the DL24P, EBC-A20, and EBC-A40L electronic loads, explain the physics of 4-wire Kelvin measurement, and show you how to identify "fake" high-capacity cells before they enter your system.
Tools & Equipment
A weak spot weld is a hidden fuse waiting to fail. In this engineering evaluation, we compare the joule-counting kWeld against the Arduino-based Malectrics and the capacitor-driven Glitter 801 series, explaining the physics of resistance welding and why timing-based welders are obsolete for high-performance lithium packs.
