Battery Basics
Batteries are like humans: they hate being freezing cold, and they hate being boiling hot. We explore the chemistry of cold-weather voltage sag, the permanent damage caused by charging below freezing, and the Arrhenius equation that explains why heat kills cycle life.
Battery Basics
Batteries are chemical devices, and chemistry is strictly a one-way street. We explain the fundamental difference between the Direct Current (DC) stored in your cells and the Alternating Current (AC) in your wall, and the "Conversion Tax" you pay every time you switch between them.
Battery Basics
Why can a Tesla travel 300 miles while an electric plane struggles to fly for an hour? The answer lies in the brutal physics of Energy Density. In this deep dive, we unpack the critical difference between Specific Energy (Weight) and Energy Density (Volume), and why choosing the wrong metric can ground your drone or stall your EV build.
Battery Basics
Batteries do not die from old age; they die from chemical murder. We explore the mechanisms of cyclic and calendar aging, the impact of Depth of Discharge (DoD), and why charging your phone to 100% every night is destroying it.
Battery Basics
If you are buying batteries based on "Ah" alone, you are likely calculating your range wrong. In this deep dive, we explain why Watt-Hours is the only universal metric for energy, debunk the "Powerbank" marketing scams, and explain Peukert's Law comparisons between Lead Acid and Lithium.
Battery Basics
Operating a lithium cell outside its specific voltage window is a recipe for chemical disaster. In this comprehensive guide, we examine the electrochemistry behind the 4.2V limit, why discharging to 0V kills a cell instantly, and why "Nominal Voltage" is the only number that matters for energy calculations.
Battery Basics
Why does your battery voltage drop when you accelerate? Why do old batteries get hot? The answer lies in Internal Resistance. In this guide, we explore the physics of IR, how to measure it correctly using AC vs DC methods, and why matching IR is critical for parallel group balancing.
Battery Basics
The most misunderstood number on a battery datasheet is the C-Rating. In this engineering deep dive, we debunk marketing myths, explain the math behind discharge rates, and show you how to calculate the true safe amperage limit of your pack to prevent thermal runaway and voltage sag.
Battery Basics
10S4P? 13S5P? Decoding the shorthand of battery pack architecture. This deep dive explains how Series (S) and Parallel (P) connections work, how they impact current sharing, and the physics of building a balanced, safe battery pack.
Battery Basics
Before you spot weld a single cell, you must master the Holy Trinity of electricity. This comprehensive guide moves beyond textbook definitions to explain how Voltage (Pressure), Amps (Flow), and Watts (Work) dictate every decision you make in battery pack design, from wire gauge selection to range calculation.
