Battery Knowledge & Engineering Guides
Practical, engineer-written guides on lithium battery chemistry, selection and custom pack design.
Battery KnowledgeLiFePO4 vs NMC Lithium Batteries: A Practical Engineering Comparison (2026)
Cycle life, safety, energy density, cold-weather behaviour and total cost — an engineer's side-by-side of LiFePO4 (LFP) and NMC chemistries, with a decision framework you can actually use.
Buyer's GuideHow to Choose a 12V 100Ah LiFePO4 Battery: A Buyer's Guide That Goes Beyond Capacity
Two 12V 100Ah batteries can perform completely differently. Here's how to size one correctly and read the spec sheet — C-rate, BMS, cycle life and the details that actually matter.
ManufacturingCustom Lithium Battery Pack Design: An OEM/ODM Guide from Requirements to Mass Production
What actually happens between “we need a custom battery” and a certified pack rolling off the line — cell selection, BMS, certification, timeline and the decisions that make or break a project.
Battery Knowledge18650 vs 21700 vs 26650: Choosing the Right Cylindrical Lithium Cell
The numbers are just dimensions — but they decide energy, current and pack size. A clear comparison of the three workhorse cylindrical formats and how to pick one for your product.
Energy StorageHow to Size a Home LiFePO4 Battery Bank: A Step-by-Step Sizing Guide
Undersize and you run out at night; oversize and you overpay. Here's the engineer's formula for sizing an off-grid or backup LiFePO4 battery bank — with a worked example.
ComplianceLithium Battery Certifications Explained: UN38.3, IEC62133, UL, CE and More
Which certificates does your battery actually need to ship and sell? A plain-English map of transport, product-safety and regional certifications — and how to plan them.
Battery KnowledgeLithium Polymer (LiPo) Batteries: The Complete Guide for Compact & Wearable Devices
Why the soft pouch cell powers everything from ECG patches to earbuds — the advantages, trade-offs and design rules of lithium-polymer batteries, and when to choose one over a cylindrical cell.
Battery CareHow to Charge Lithium Batteries the Right Way (and Make Them Last Years Longer)
A few simple habits — the 20–80 rule, the right temperature, and how to store a battery you're not using — can double the useful life of any lithium battery. Here's the engineering behind them.
Battery KnowledgeHigh-Rate Lithium Battery Packs: Powering Tools, E-Mobility and Drones
When a load needs huge current in short bursts, ordinary cells fall over. Here's how high-rate packs are engineered — continuous vs peak current, the role of the cell and BMS, and where the heat goes.
