Includes links to Pack Builder and C-Rate tools to help plan safe, efficient systems. Lithium Battery Basics — why this matters Whether you’re sizing a solar battery bank, estimating inverter runtime,…
Depth of Discharge (DoD) Explained: Life vs Usable Energy Depth of Discharge (DoD) is the key metric that defines how much usable battery energy you can safely draw from a lithium pack while balancing cycle life and system cost. This guide explains DoD basics, battery life trade-offs, cycle curves, and cost per kWh — with…
BMS 101: Protections, Balancing & Why It Matters Learn how a Battery Management System (BMS) protects your pack with over/under-voltage cutoffs, over-current protection, temperature limits, and cell balancing — plus practical guidance for picking the right BMS and avoiding common pitfalls. Try the Pack Builder to design compatible series/parallel layouts. What is BMS 101…
Choosing System Voltage: 12V vs 24V vs 48V Choosing system voltage (12V vs 24V vs 48V) affects cable size, efficiency, inverter selection and safety. This guide explains when to step up from 12V to 24V or 48V, how voltage changes current and conductor sizing, and practical rules for system design. Why choosing system voltage…
Cycle Life, Calendar Life & Storage SOC Learn the difference between cycle life and calendar life in lithium batteries, and how storage state of charge (SOC) affects long-term performance and safety. Use this guide to extend battery lifespan in solar, backup and EV applications. Why battery lifetime is more than just cycles When you…
Charging Profiles: CC/CV Basics for Lithium Lithium batteries charge in two stages: constant-current (CC) and constant-voltage (CV). Understanding this charging profile is key to safe and efficient use. What is a charging profile? A charging profile describes how current and voltage are applied to a battery during charging. For lithium chemistries like LiFePO4 and…
Fusing & Protection Basics for Low‑Voltage DC Proper fusing protection for low-voltage DC systems is essential for preventing electrical fires, protecting expensive equipment, and ensuring the safety of battery installations. Many DIY builders and even experienced installers misunderstand the primary purpose of fuses—they protect the wiring first, not the load[web:22][web:25]. Understanding where and how to…
