新人小白求指导，各位玩短波的时候野外架台有什么便宜又好用的蓄电池供电方案

最近论坛刚好有人卖[炸飞老铁牌锂电池](https://forum.hamcq.cn/d/6623)，要不要看看？我自己买的M哥17Ah电池，玩FT8足够用了，但是有点贵动手能力强的也可以考虑自制，论坛里可以搜到相关帖子

@"BG4IJK"#p79773 要的就是便宜又好用，至于炸飞老铁嘛，价格便宜我先飞再说😁

淘宝有99块15ah的磷酸铁锂电池，买12.8v的刚刚好

@"BG4IJK"#p79773 名字听起来就晦气

不嫌重就去修车铺捡一个铅酸。如果手头没工具自组炸飞老铁成本也不低

@"BA7NID"#p79799 NID老师这个DIY的移动电源有图纸吗？我也想组装一块。

@"BG5CXA"#p79812 哪里需要图纸啊 4串电池串起来加保护板就行了

@"BA7NID"#p79825 大抵是想问问BOM，用的什么型号电池什么尺寸箱子

自用移动电池包😋 [upl-image-preview uuid=bdc99e00-c090-4741-a70e-44892319d60a url=https://storage.hamcq.cn/2025-09-22/1758547923-412406-gv-ilhnw4aamlsl.jpg alt={TEXT?}]

What are the solutions to problems with outdoor rack batteries?

New ham radio operator, Xiao Bai, seeking guidance. What are some affordable and effective battery-powered setups for operating a shortwave radio in the field?

BG4IJK

Recently, someone on the forum was selling.Zhe Fei Lao Tie brand lithium batteriesWould you like to take a look?

The 17Ah battery I bought myself from M, which is suitable for FT8, but it's a bit expensive.

Those with strong practical skills can also consider making it themselves. You can find relevant posts on the forum.

BI5UNC

BG4IJK I want something that's both cheap and effective. As for flying away, if it's affordable, I'll go first.😁

BI7ALG

BG4IJK The name sounds ominous.

BD8DIN

On Taobao, I found a 15Ah phosphate iron lithium battery for 99 yuan, which is exactly what I need at 12.8V.

BA7NID

If you want to save money, the only option is to assemble it yourself. The battery capacity is about 1 yuan per amp-hour. You can buy cylindrical batteries like 32140 if you have the tools, or ask a vendor to convert them to nickel-based batteries. Alternatively, you could use screw-type batteries and then connect them in series with a protective board. Iron lithium batteries are still quite safe. I've been using this battery pack for over a year now, and I usually keep it on the bottom of my desk.

BG5CXA

BA7NID Does NID teacher have a diagram for this DIY portable charger? I also want to assemble one.

Yur1

If you don't mind it being heavy, go to a repair shop and get a lead-acid battery. If you don't have the tools or experience to assemble one yourself, it will also be expensive.

BA7NID

BG5CXA Where do I need to get the diagrams? Just connect the 4 batteries in series and add a protective board.

BD3ROR

BA7NID I was likely trying to ask BOM about what type and size of battery they use.

BG5VCU-VK2VCU-AK6CU

Portable battery pack for personal use😋

BD8DIN

BG5VCU-VK2VCU-AK6CU Wow, do you have any diagrams or links? I'm looking for some guidance.

BG5VQE

You can refer to the exterior for reference.https://forum.hamcq.cn/d/3427

BG5VCU-VK2VCU-AK6CU

BD8DIN Internally, it uses 4 x 32700 cylindrical batteries, a protective plate (with passive balancing), and an external capacity meter (measures voltage, not ampere-hours). Various interfaces are included. The active balancing module has been converted into a plug-in component to reduce internal wiring complexity. The outer shell is made of aluminum alloy, model K79. The front and rear panels are printed circuit boards (PCBs).

Compatible with the IP2366 bidirectional charging and discharging module for USB-C 140W charging and discharging, using PD3.1 protocol. The case model is not remembered, haha.

BG6QFO

The battery for the wine bottle, although manufactured in 2017 with a 4S-16.8V configuration and 148Wh capacity, will have some degradation over time. However, at under 100 yuan, it's still quite capable.

BH2VYJ

A 12V 50Ah phosphate iron lithium battery from Taobao, which is enough to power a device for one day.

BH1XWE

Four-cell phosphate iron lithium batteries are just right. I'm buying a large, used battery directly from BYD, adding a protective plate – it's very affordable. Since we're already using radios, assembling the battery ourselves isn't too difficult.
