Core Technical Guides

• Battery Management System (BMS) Protection Explained
  Understand how the BMS protects the battery from unsafe conditions such as overcharge, over-discharge and excessive current.
• Depth of Discharge (DoD)
  Learn how usable capacity and discharge depth affect battery lifespan and long-term performance.
• Continuous vs Peak Current
  Understand the difference between sustained current and short surge loads when selecting a battery for your application.
• Internal Resistance
  See how internal resistance affects voltage drop, efficiency and battery performance under load.
• Calendar Life vs Cycle Life
  Learn the difference between ageing over time and wear caused by repeated charge and discharge cycles.
• Voltage Drop and Cable Sizing
  Understand why cable selection matters, especially in 12V and 24V battery systems.
• Lithium Battery Charging Stages Explained
  Learn how correct charging supports safe operation, battery life and system performance.
