Why Does a Drone Battery Voltage Sag Under Payload? Causes, Risks and Battery Selection
Why does drone battery voltage drop under payload? This guide explains drone battery voltage sag causes, how to distinguish normal behavior from faults, how to check ESC and flight-controller readings, and how to choose a suitable UAV battery pack.
Does Higher Wh/kg Always Mean Longer UAV Flight Time? 400 vs 450 vs 500 Wh/kg Explained
A higher Wh/kg rating stores more nominal energy per kilogram, but it does not guarantee proportionally longer UAV flight time. This guide compares 400, 450 and 500 Wh/kg batteries and explains how pack weight, discharge capability, voltage sag and usable energy determine real endurance.
Li-Ion Battery Cell vs Module vs Pack: What Should You Specify?
A battery cell, module and pack are not interchangeable purchasing terms. This guide explains how series-parallel configuration, BMS, enclosure, connectors and thermal design differ at each level, and what to specify in a battery RFQ.
High Discharge Rate LiPo Battery: Does a Higher C-Rating Matter?
A high discharge rate LiPo battery supplies the current an FPV drone needs without excessive voltage sag or heat. This guide explains what C-rating really means, why a bigger number is not automatically better, and how to size a pack from measured current.
Does a Drone Battery Pack Need a BMS?
Find out whether a drone battery pack needs a BMS. Learn how FPV, industrial, and custom Li-ion UAV packs differ, when a smart battery adds value, and which protection strategy to choose.
What Is a LiHV Battery and How Is It Different from LiPo?
Learn what a LiHV battery is, how it differs from LiPo in voltage, performance, flight time and cycle life, and whether you can charge LiHV with a normal LiPo charger.
How Long Do Drone Batteries Last? What Affects Battery Life
Learn how long drone batteries last per charge and over their service life, what affects flight time, and how to improve battery performance and care.
