no, they do not sell the cable to connect flight battery to your goggles. They however do sell a XT60 to barrel adapter, where you can use any LiPo battery (as long as the voltage remains within specified range) to power the goggle. I am not sure but I presume that the goggle will auto detect the cell count and will warn you about battery being empty before it is too late. The normal LiPo's do not have BMS of any sort so you will deischarge them to too low voltage if you don't know what you're doing. The so called intelligent flight battery however will most likely shot down way before the goggle can warn you, leaving you with black screen. You think you have the time to flip the switches but I can think of many cases where you do not and you will crash and will be crying here on the forum how bad DJI is and how unfair the life is. So don't be stubborn, unless you know what you're doing (which in this case I doubt) and leave this option alone. If you don't have the normal LiPo's just buy another goggle battery and enjoy safe flying.
"The so called intelligent flight battery however will most likely shot down way before the goggle can warn you, leaving you with black screen."
How is the Intelligent Battery is different from third-party 6S packs in this respect?
A guess is that the Intelligent Battery will shut itself off before it's depleted, and its shutoff point is at a higher voltage than will cause the goggles to warn?
Given that DJI says the Goggles can be powered with the XT-60 connector cable and either a 4S or 6S battery. They specifically sell the cable for this purpose, so it's clear -- when coupled with the fact that the Goggles also successfully power from the Goggles Battery at only 7.4v (lower near depletion) -- that the voltage regulation is pretty robust. It works from 7.4 to 25.2 volts!
What is not clear, is whether the warning system will adequately protect your flight, and your battery, when you use anything other than the Goggles Battery. It is not hard to imagine an algorithm that detects the incoming voltage, then classifies the battery type. This sort of thing is done all the time in other battery chargers that can auto-detect and charge, for example, a AAA or a 18450. Since the 6S, 4S and Goggle Battery voltage ranges are disjoint, it seems quite possible for the goggles to warn as each battery type approaches depletion. Do you know whether this is the case? And do you have specific knowledge that it won't work with the Intelligent Battery once I solve the physical connection issue?
You also cautioned that I could experience a sudden unexpected blackout while flying with the Intelligent Battery powering my goggles, and that there are situations where that could cause a crash. That's great advice! If I cobble this solution together before I can get another Goggle Battery or two, I will certainly test the solution in stress-free flight to the point of failure until I understand how it behaves. |
