准备做一批12V15A户外野架便捷电源材料采用磷酸铁锂电池 40A保护板包含电流表电压表接线端子基础方案是这样后期可按需求定制XT60接口等大小大概八重洲FT891大小自己在用实测ssb通联 100w功率大概3-5小时高频通联半天没有问题开车价格大概200以内不知道是否有市场希望各位友台提出宝贵意见 [upl-image-preview url=https://storage.hamcq.cn/2024-12-18/1734523124-222240-mmexport1734523110828.jpg]

@"BA7NNC-JOE"#p46375 综合考虑体积还有成本 15A的磷酸铁锂很合适

建议13.8V 动力电芯，我自制了两个12V，一个13.8V便携电源，感觉电台用还是13.8V方便

@"BG5CJI"#p46572 抄收了可能我没有表述明确用的33140磷酸铁锂电芯满电理论14.8v 实测13.6-13.8v

某宝上12.8V 12Ah，放电电流15A，XT60口放电，DC口充电，卖近200元，销量还可以。加电流表电压表，能定制XT60口的话，200左右应该有市场。

体积、指标、价格都合适，可以接受，开干，订一个！

Preparing to build a set of 12V 15A portable outdoor power supply with battery box.

I agree! It's amazing to see such skillful craftsmanship. The price is also very reasonable, keep up the great work!
The battery I use when going out is a fully charged one, consisting of a 240Wh battery and a 200W solar panel. The cigarette lighter has a maximum output of 12V 10A. The frame with a 25W motor provides unlimited power from the sun, while the pure battery lasts for 40 hours of communication and more than 16 hours of listening. If the new B model uses short-wave in the next year, an estimated output of 15W should be around 5A, which is still sufficient.

BI1TSS Wow? So portable solar panels can now achieve such high conversion rates?

BD8DFK

BI1TSS This will increase the noise level.

BI1TSS This is also very good.

BI1TSS

Liridice This size solar panel has a conversion efficiency of 23% to 26%, providing actual power output of 30W to 70W depending on sunlight conditions. The 500DR receiver consumes 6W, and the 25W transmitter consumes approximately 70W. Taking into account the fill factor, the average actual power consumption is less than 20W, effectively providing near-unlimited runtime.

BH3NZN I look forward to seeing a finished product that meets expectations, and I would be happy to support it.

BI1TSS

BD8DFK I connected the radio directly to the car's charging port, and I didn't notice any impact from the UV. I also use this at home, so I don't need a separate power source anymore.

I'm driving around, kicking some cans. I'm also looking for a battery.

BI9ANL I've roughly calculated the cost of building this myself, and it's around 170-180 yuan. This includes: battery (40A protection board), charger, case, connectors (XT60 base), DC base, switch, current/voltage meter. This doesn't include various copper wire materials. I'm not sure which courier service to use, and I don't know how much the shipping will cost. I also haven't figured out the best way to order parts. There may be both a basic and a high-end version available. I'm posting this because I want to gauge interest. I'm just an amateur radio enthusiast. After getting into shortwave, I built this 13.8V 15AH battery myself. For building batteries, I'm basically a beginner. Perhaps there are better solutions or more cost-effective options that experienced users might suggest. When I build something, I want to do it right the first time and have all the necessary parts. I hope everyone can provide valuable feedback.

Shipping batteries definitely presents a challenge. It's difficult for retailers to ship them, but individuals find it very hard. Would it be possible to create a kit that doesn't require soldering?

BH3NZN

fang Soldering is not required, but a soldering iron is needed.

BG5BJM

Logistics is a major issue; I can't ship items with batteries, especially homemade ones.

The appearance should be attractive and simple.
Approximately how much does it weigh? I estimate it's around 1.5 kilograms.

It can support one, which perfectly matches my need for an external power supply.

BH3NZN

BG5BJM The weight is actually not heavy, which I also like. However, it has all the necessary functions. The small portable radio can be powered by batteries, and the larger radio can be powered by a power supply. This design is seamless and doesn't look out of place.

BG4IIT

I support starting production. The feedback we've received has been comprehensive, but I think we need to make sure the outer shell is more durable and provides better protection when used outdoors.
