为什么做这么个电池呢，主要是考虑电池能在野架、爬山时方便携带、或者高铁出行当充电宝。具体想实现的参数/效果如下： 1、能带的动FT891使用100W输出（SSB模式）； 2、一般的发射频率大概可以玩2.5小时左右（5Ah）； 3、初步计划做一个5Ah的437克，10Ah的估计750克。采用三元锂电池，铁锂太重了，不符合便携性的要求； 4、设计一款二极管动态降压功能电路，电芯满电时传入二极管降压，电压下降时自动切换到不串二极管，可使电池输出电压在14到15.8V左右(无干扰高效率的调整方式，解决使用三元锂的高容量密度和电压过高矛盾) 5、具有typeC快充电和放电接口，可以给手机、笔记本充电 6、采用牢固的外壳，比如铝合金外壳加喷漆、激光丝印

用的软包电池还是硬壳电池？一直觉得软包三元锂的安全性还是比较差的…

目前电路板已打样回来测试，具体充放电情况如下： 1、typeC口对iPhone13充电，20W[upl-image-preview url=https://storage.hamcq.cn/2024-09-01/1725173799-860248-111.webp] 2、typeC口对老款荣耀手机（型号未知）充电，20W [upl-image-preview url=https://storage.hamcq.cn/2024-09-01/1725173800-104868-222.webp] 3、typeC口对笔记本电脑（ThinkPad T480）充电，40W（20V/2A） [upl-image-preview url=https://storage.hamcq.cn/2024-09-01/1725173800-225114-333.webp] 4、荣耀手机66W快充充电器通过typeC口对口香糖电池充电47瓦（电流显示-3A表示是对口香糖充电，而不是口香糖对外放电） [upl-image-preview url=https://storage.hamcq.cn/2024-09-01/1725173800-351354-444.webp] 5、总结充放电测试总共花费了2个多小时，板子发热较大，尤其是电感，在预估范围内。总体来说基本功能无大碍，XT60相关电路都是和一代一致，只是换成XT60母座，转接线还未到，所以未测试。应没啥问题。接下来是整机安装外壳做进一步的测试以及软件方面的优化，还有就是想办法找支持100W快充的手机或者电脑来测试口香糖的typeC口大功率放电功能以及稳定性未完待续……

只要换母座，我就相信楼主的电池【爆哭.jpg】

DIY portable power bank for use with radio (specifically designed for radios).

BH7FFB

The outer casing has been completed; the remaining work involves the circuit board.

BG2VWO

Are there any more groups?

BD8ENX

Did I arrive late?

BH7FFB

They are all sold out. The current batch of 150 sets has already been shipped, so if you're still interested, please follow my video channel "Old Eagle Hobby Radio" and leave a message or add me on WeChat to join the group.

UmenShiro

BH7FFB That one? Douyin/TikTok?

BI1TRT

What do you estimate it will sell for? I really need this portable power source, especially since I'll be traveling by high-speed train. I definitely need to check the product specifications.

BG2EWI

BI1TRT Just create a compliant label yourself and attach it.

UmenShiro Regarding carrying power banks on high-speed trains and airplanes, please refer to the labels on the devices themselves; those without proper markings are not allowed.

Hangying

The chewing gum was both thin and long.

BH7FFB

The back of the packaging states the actual capacity, and it has been used by multiple people on high-speed trains and airplanes without any issues reported. It may appear to be of a higher quality than typical consumer products. Someone has also reported using it on an airplane.
Delivered to Canada and Indonesia.

BI1TRT

BH7FFB I've been searching for "Old Eagle Amateur Radio"! I've already left a message, please add me to the group.

BH9BZB

A long-time "chewing gum" user, for the dumplings wrapped in vinegar.😂. It's generally fine to go out for about two and a half hours.

BA7MAT

I'll also mark this.
One generation, 5Ah&Second generation 10Ah battery users are enjoying it!

BD6OC

BA7MAT Surprisingly, we made the same choice.😀

Apple recently released the latest Mac mini, which includes a built-in power adapter. The total power consumption of the entire device is around 50 watts, plus an additional 155 watts from the Thunderbolt port for external power supply.
I estimate that within a short time, there will be a modification to use 12DCIN, and I also estimate that the gum batteries will work. So, I'm marking this down for later.👍

BA7MAT

fang You could try using a 12V lure line.

BH3XZT

Dear friends, please pay attention when purchasing the lure lines. The radio's voltage is 13.8V, and the 12V lure line has a relatively low voltage, which cannot support full-power transmission of the radio. You need to purchase a 15V lure line.

BH7FFB

These are 150 boards produced in small batches.

BH7FFB 大哥，微信群拉一下，谢谢

Where to buy? When searching for "Old Eagle Hobby Radio" on Taobao, you will only find Old Eagle antennas.
