Finding Out Input Voltage Requirements

Different FPV Goggles may need differing battery voltages. Here are a few of the most popular FPV Goggles and their input voltage varieties:

  • DJI Goggles V1: 7.4 V– 17.6 V
  • DJI Goggles V2: 11.1 V– 25.2 V
  • DJI Goggles 2: Not defined (TWO)
  • HDZero Goggles: 7V– 25.2 V
  • Walksnail Goggles X: 7V– 26V
  • Skyzone SKY04X: 6.5 V– 25.2 V
  • Fatshark HDO2: 7V– 13V

How to Estimate Battery Life

To approximate battery life, you require to understand 2 things:

  1. The capability of the battery.
  2. The existing draw of the FPV Goggles.

Battery life can be approximated by dividing the capability of the battery by the existing draw of your FPV Goggles. The Walksnail Goggles X draws about 0.35 A at 25V. This suggests a six 1000mAh LiPo would last approximately 2 and a half hours.

Dedicated Two LiPo Battery

Many FPV Goggles, consisting of older designs from Fatshark, Eachine, Skyzone, and Aomway, assistance two input. This Tattu Two 2500mAh may be the most safe alternative. This battery is particularly developed for FPV safety glasses and features a 5.5 mm barrel adapter (DC3.5). It includes an LED battery sign that reveals the battery level.

Personally, I choose utilizing Li-ion battery loads for powering FPV safety glasses since they have a greater energy density than LiPos. This suggests that for the very same weight, Li-ion batteries last longer than LiPos. This is particularly useful as FPV safety glasses do not draw a great deal of existing, so the low discharge rate of Li-ion batteries is completely appropriate.

The Auline Four 2600mAh is a great alternative. The majority of contemporary safety glasses support a four input, and 4 18650 cells aren’t too heavy to bring in your pocket while flying, yet they still use exceptional battery life.
