最近大疆不是发布了新的户外电源么，我想买一个1度电版本的，广州和浙江国补完才2100左右，但是我查了一圈资料，发现AC接口最高支持10A，sdc接口官方转xt60线只支持12v10A也就是最高120w，官方的配件除了通过AC口接可调电源，好像没有别的办法能输出ft710需要的13.8v25A，所以想请教各位大佬，能不能通过sdc的改装或者加装dc-dc稳压来实现sdc接口的13.8v25A的输出？

不行，别想了，私有协议这个东西蛮鸡肋的，你开AC之后电台会有干扰，用DC没有直通出来的方法。我用的是这种方案，AC逆变220V插求精，ac一开底噪瞬间S8S9 [upl-image-preview uuid=31e0055c-964e-4495-9720-a9fd2f229438 url=https://storage.hamcq.cn/2025-05-27/1748314945-608322-img-20250527-110121-compressed-1748314936511.jpg alt={TEXT?}]

710在12v应该都能满功率输出。然后大疆有一个1kw的车载双向模块，那个可以调到13.8v 70A最大。如果高功率可以用那个模块。

喜欢直出的买九号电源，那个点烟器直出13.6V

这个接口有最大电流保护，最高10A电流。

@"BI7KGD"#p67105 这个车充好像不能直接输出的，需要检测到有电瓶接入才会进行功率输出。

@"Moonlight"#p67103 直接再带一个电源的话，大疆AC口限制10A电流

@"BI7KGD"#p67105 这个我研究了一下，好像是不能给感性负载用

@"BG5BQB"#p67123 这个参数感觉没有大疆的好啊～

@"BG7MVN"#p67171 是好像是这样的，好像是只可以给阻性负载用

Can a new DJI portable power station be directly connected to a 13.8V 25A output via an SDC interface?

BH2VKX

Recently, DJI released a new portable power supply, and I'm interested in buying one that can provide 1 degree of battery capacity. The price in Guangzhou and Zhejiang is around 2100 yuan, but after researching, I found that the AC interface only supports up to 10A, and the official SD card to XT60 cable only supports 12V 10A, which means a maximum output of 120W. Besides connecting an adjustable power supply through the AC port, there doesn't seem to be any other way for the official accessories to output the required 13.8V 25A for the FT710. Therefore, I would like to ask experienced users if it is possible to achieve a 13.8V 25A output from the SD card interface through modification or adding a DC-DC voltage regulator.

Moonlight

Should I just add another power supply?

BH2VKX

Moonlight If you add an additional power supply, the DJI AC port has a current limit of 10A.

BI7KGD

The 710 should be able to output its full power at 12V.
Then DJI has a 1kW in-vehicle dual-way module that can be adjusted to a maximum of 13.8V and 70A. If high power is required, this module can be used.

BG7MVN

BI7KGD It seems this car charger cannot directly output power; it requires a battery to be connected before it can start delivering power.

BH2VKX

BI7KGD I've looked into this a bit, and it seems like it might not be suitable for capacitive loads.

BG5BQB

I like the direct-output power supply, specifically the one that provides 13.6V for vaping devices.

BH2VKX

BG5BQB This parameter doesn't seem to be as good as DJI's.

BG7MVN

This interface has a maximum current protection of up to 10A.

BH2VKX

BG7MVN It seems like it's only suitable for use with resistive loads.

BH2VKX What's the point of taking it down? I never take my shortwave antenna out during thunderstorms; it's all about luck.😄

BG5DUT I admire you for being a true cultivator.

BH2VKX

Yuluoxk I finally have an answer, thanks to C for helping me understand. After watching all the disassembly videos, it seems that this inverter has a major problem, as all the shielding methods are ineffective. Now I know that using a private protocol bypass is no longer possible.
There's a blogger on B站 who has managed to crack the 12V protocol, but simply specifying the current isn't enough. I have contacted DJI technical support multiple times, and it seems that achieving the required 42V sdc current is only possible when charging directly from the battery pack using mains power. Therefore, cracking the current appears unlikely.

BH2VKX I always use two power supplies.
What's the use of a 0.7° temperature difference for things like computers? My brand is Platinum D. I tried it without interference.

BG6RCW

That's amazing! I built a DIY power supply using salvaged parts from an electric car: a 50Ah phosphate iron lithium battery in a 4-series configuration, without any protective plates, connected to a drone balancing head and charged with a B6neo charger. Using a gallium nitride (GaN) phone charger is very convenient for charging the battery itself.

BH2VKX

BG6RCW 总是对锂电池感觉怕怕的，所以合计是不是大疆的稳妥一点～

BH2VKX

BG2EFX 这样也不错

I replied to you in the group. The power supply cannot be directly connected. The only way is to use an AC 220V power supply for a radio, and then the radio power supply outputs 13.8V to the 710, and both the DJI power supply and the radio power supply must be kept separate, and you shouldn't connect them directly on top of each other by running a cable between them. Also, both the radio power supply and the radio should be grounded separately.

BH2VKX

BI1IZF 嗯呢，谢谢大佬～才看到群里消息～
