This is a really helpful video Josh, even two years later. The power aspect is one of the most important parts of SHTF radio gear. Many videos go into ham emergency kits, but fail to really cover the battery solutions that could work, especially when there is no power available at all. Glad that LiFePO4 batteries have come down in price since the video was made. Good job!
For automotive installation of HF 100 watt radios---use 12 gauge or even better 10 gauge wire and run it directly to the battery with fuse or breaker in series. Add an appropriately sized relay and switch the relay from key switch if you want the radio to power down with key.
Great video Josh, this topic had me baffled for a long time and it is so important too. Wrong amperage/voltage etc… can be very costly to us Hams. Just when I think I’d worked it all out you make a great video explaining it, lol. At least you have confirmed I had grasped the subject correctly.

Any all in one power stations - jackery, goal zero, etc, that would work for ham radio? I know they're based off watts and not amps, but looking to build one out of a lifepo battery costs more than an all in one. Bioeno makes a box but doesn't have the solar charge controlled built in.
Wanted to say thank you for this video. It helped me figure out what I needed to power the SAR radio trailer I get to build out. (The team I am on is a small one in WV and I'm doing their tech/radio stuff for them.)
How would you recommend wiring a ham radio powered of off a portable battery to a trickle charger. I want to install a FT-857 in my vehicle that is powered by a LiFePO battery. I want to use a 12v trickle charger to charge the battery while I am using the radio in the vehicle. Is it advisable to connect the charger to the battery terminals at the same time as I am drawing current from the battery, or do I need a something in between the two. I am using a Dakota LiFePo battery and a BPC-1503CAR charger.
I've used so many different external portable batteries and my favorite are definitely Bioenno batteries for the power/dollar. I'd love to hear what charge controllers you think are good - also maybe different solar options. Maybe you already have info on that.... I'll have to look
Some of the upgrade batteries for the Baofeng radios have a DC input jack on the battery themselves (as well as the normal charge pads to use the stock Baofeng charger). There's also the battery packs that take AA batteries, as well as the one that contains no batteries but allow you to plug into the DC port in the car. There's also the far more expensive Battleborn lithium batteries if you're using solar in the shack to power equipment.
Hey Josh, here's a question. What if someone is interested in QRP? 5 watts for a few hours when used. What Ah Li-ion battery rating would be proper for that type of use? Would 3 Ah be enough?
I am looking for such a cheap, readily available and flexible solution. I like that it uses standard components (there will be plenty empty powerbanks available in a grid down situation). Charge them with your solar panel (portable or from the grid connected panels with a emergency off grid solar inverter) and you can hand out full powerbanks and power a lot of radio's.
I lucked up with a switching power supply it is very quiet. I put it on a scope and it has a really clean power output. It was a cheapo so was a gamble.

Makes me feel fortunate that my vehicles cig lighter is straight off the battery using using around 8 gauge wires straight from the battery and has a 30amp fuse. Never had any issues. The most power i run mobile is only 50 watts so my setup serves me well.
hello, I'm looking for a way to store my radio presets on my boat when I cut off power to the helm. Do yo know if I can do this with a similar battery? NOONE has a video out there showing this process. I think it would be very beneficial. I don't think the radio needs much juice to "remember' those presets. Thoughts? thank you so much.
Most all switching power supplys produce noise but the high speed switchers are easier to filter and the higher frequency the smaller the caps needed to filter them.
I recently purchased an STP 1330 it's got really good numbers on it and I love that it's got the cigarette adapter right there for other shop needs. Anyone have any thoughts about this unit? It's only 30 amp but it is a switching power supply it's regulated and it specifically made for communication equipment. And yes the 200 amp hours of batteries got to be a bit heavy.
How do I regulate/control the battery output to the radio to have a constant Voltage? I see small variations in my Voltage while operating with batteries and I don't like it, not sure if it can cause problems in a long term. Tks for the video!
Oh Great Ham One! We thank you for your insight into the power! Just seems the auto focus keeps getting you though... But how crisp and beautiful the image is!
@@HamRadioCrashCourse yes that’s the product showcase feature. In general it relies upon autofocus which doesn’t work well indoors here so I turned it off. It’s not a bad concept but I think it needs improvement. I just set manual focus now.
OK, I have a question about vehicle power. The typical car/truck, the battery isn't far away from the radio. However, in a semi truck there's a lot more real estate between the battery and ground to the radio. The batteries are usually mounted in one of three locations; step box under the door, battery box under the sleeper (not very common anymore) or in a battery box mounted between the frame rails usually a foot or two behind the back wall of the sleeper. Would the extra distance of power wire effect the radio? Now most trucks do have red/black screw poles (12v) for CB somehere on the dash or overhead CB din and works just fine but I'm not to sure if it will be sufficient for a Amateur radio. Also I am finding a bit of conflicting information on Amateur and CB antenna mounting and spacing. I would like to keep the CB up and running at all times for traffic information but don't want the HAM interfering and bleeding over into the CB. Any ideas?
Thanks Josh. Have you found a good way to charge your Bioenno using the vehicle? It would be handy to charge one LiFePO4 battery while using another, but most chargers want 120VAC. Seems like overkill to use an inverter.
@@Dreamlgider ah, I don't have one in front of me, but it probably works like the FT-2000D it is external, but it ships with the required power supply. The yaesu specs say it requires mains AC voltage.
Yes, LiFePO4 is more expensive up front, but the average lifespan of a lead acid battery is 600-800 cycles (assuming you don't run it down below 50% which will kill it). A lifepo4 battery is good for 3000 to 8000 cycles, so it has 10 times the lifespan. If you baby it and only charge from 20% to 80% it will last for decades. Lifepo4 is cheaper in the long run, and safer.
Hi. Can you please advise for a battery for the anytone 578 for a manpack? I was looking into 12v lithium polymer. Would those work? I'm really new. Thanks
It is all over the Web about converting those ubiquitous computer power supplies over to bench supplies, and it seems that everyone has one sitting in their basement. And it alsoseems that a lot of them have 12VDC @ 40+amps, and if you add a buck boost converter, you have a PS that gives you 5VDC for USB and up to 35VDC of adjustable, plus a fixed 12VDC for your radios.

HIIII I M NEW BEE IN HAM , I HAVE A QUESTION , IN POWER GRID FAILURE , CAN I USE MY HOME INVERTER SQAURE WAVE BATTERY BACKUP TO POWER LINEAR POWER SUPLY (30 AMP 13.8 V ) WHICH GIVING POWER TO IC7300
I've been a ham for quite a while and I wish this info was available when I first started. My reasoning for learning these comm options was SHTF. Now my question to you is, when SHTF is there a counter measure to help prevent or protect against government jamming frequencies? I see it being, NO. There is nothing we can do. And pray this never happens. But we never know when this may be the case.
There are so many precautions to take and think about when it comes to connecting your mobile radio directly to your car battery. So to avoid that I was just thinking........why not just purchase a separate stand-alone battery? With a stand-alone battery you don't have to worry about the radio effecting other components to the car because the separate stand-alone battery will only be dedicated to the mobile radio. It would cost me almost nothing to build my own compartment in the trunk of my car for a stand-alone battery. What do you think of that?
@Ham Radio Crash Course. I Have a 20 Amp 13.8VDC Linear Regulated Power Supply highly stable, high quality. My question is on the unit it says 20 AMPS Constant / 22 Amps Surge. What is the 22 AMP Surge for? And What does it do? Thank You. Love all the info from this channel.
Good that you pointed out HF radios need about 21A to put out 100W. I bought a 12v LiFePO4 battery for portable work. I transmitted with 50w or less, and the battery lasted a very long time, longer after I attached a solar panel and charge controller. I now have a kind of semi-permanent shack (literally, a shack in an olive grove) and power my devices 100% with batteries and PV. I would like to be able to transmit with a full 100w, but the LiFePO4 battery says, " no can do." That has to do with the battery chemistry and construction. So now I have go buy a more suitable battery that will deliver constant 20-25A, which means in general a bigger, more expensive battery. My XYL is not amused. So keep the constant output current in mind when you buy a battery. If you want 100w RF output, you will be dissatified with a battery like mine. 73!
Hello Tim, my batteries from "Eremit" create 100 W on the TRX. With 18 Ah, 50 Ah and more. With built-in BMS. Arthur von Funkwelle's TH-cam channel is also testing this on the FTDX 101. That works with it, 73 Jürgen DK4BU
One of the best upgrades I did for my car battery. Get a automotive AGM battery, I got mine from autozone there Platinum series. Thy take deap discharge better and the on time is longer when the motor is off. The voltage sag is less when starting the motor. The one in my van is going on 7 years and still strong. Just replaced the battery in my other vehicle the one.
2:42 WoW 21 to 30 Amp at 100 volts is 2,100 to 3,000 watts. At just under a dollar a watt (August 2024 U.S.), that battery (Jackery, Bluetti, EcoFlow) just got real expensive for just one hour of use. I was thinking the Jackery 300 I use to power my CPAP machine would be enough, not even close !
This seem to be all quite expensive and complex gear. Do you have simple solution for simple hand held radio's. For example, solar charging a simple usb power bank, and use that at night to charge your recharge the hand held radio's? I do not plan on continuously transmitting with 100's of watts in a grid down situation, just with local living family members / friends. (Even The light saver max is already 400$)
Instead of making these radios where a power supply is needed, why doesnt ICOM, Yaesu and Kenwood make their radios with regular plugs that can be plugged up into a regular wall socket in the home? How hard can it be to make a radio that plugs up into a wall?
You want them to include a ac/dc power transformer in the radio body to make it heavier and more expensive? What about the people that only have 12 volt dc in their shack or off grid setup?
@@HamRadioCrashCourse Paying a little extra for shipping would not be more expensive than going out and buying a power supply. No where near as expensive as getting a power supply. Even the cheapest power supply for your average ham radio is about 4100.00. There is not way that shipping would be $100.00 more if they included an AC/DC power transformer in the radio. No way.
@@HamRadioCrashCourse As far as off the grid setup, they can still make the make radios that have the all all connections in one radio including a plug.
Companies don’t want to make two radio models one with a different case and power supply and one without. It’s not worth the effort and costs. Further, power supplies usually power more than a radio in the shack. So that’s an issue. If the supply fails, a cheap part, do you ship the whole radio back? FYI, this was tried in the ham radio market. The customer base didn’t want it.
Hello everybody, I would like to get my L1 and L2 Ham license. My intention is simple, monitor for what is stirring in the weeds and in the event of an emergency be able to transmit.

@HamRadioCrashCourse, @Josh... Being a noob to Ham radio I caught wind of something the other day that I was hoping you could clear up for myself and others who may hear the same thing at some point...... Can a person use a CB 'Linear Amp' for Ham radio?..... I have tried to look this question up here on the web, but I'm just not having any luck. Personally I kind of feel the person who told me was being a douchebag and hoping I would fry something so they could be entertained at my expense. I am currently studying to get my license and hope to take my test soon. Thanks my friend, love your content!! Keep up the good work and hope to hear back from you!

Yes, a while ago, I had a local two way radio dealer, install a cable from the battery 🔋 to the passenger compartment with the appropriate connector to match my mobile radio, which will not perform well on below the required voltage, such as a portable battery 🔋. 73 de W2CH, Ray
such a hassle to find the power supply from your link, you should have a direct link to item.your loosing out money, jut easier to input name of item on amazon,.just saying
If you are running power from your mobile battery and place a properly sized fuse in line at the battery connection you will never have a burned wire, because, a fuse is there to protect the wire, not your appliance...... radio or equipment!
A suggestion: you sometimes say "amperage" and other times say "current" and that can be confusing to a beginner. "current" is really the correct term.
I **REALLYYYYY** wish someone would make an HT that would charge directly off of USB-A/C... cmon... Everything is made that way. I've used some USB-A to DC adapters but they are all noisy. I want a damn USB jack directly on the radio.
@@HamRadioCrashCourse Good point, but that's what you get when you charge a 7.4v battery over a 5v USB port. Solution: have multiple batteries. Continue operating while charging off USB. Or do what the rest of us do and get an HT with a 12v charger. I was just pointing out that USB charging exists for an HT.
for some reason that is apparently beyond me, those Bioenno bastards charge far more than they need to for their gosh-darn batteries compared to almost any other brand that I've researched............. Apart from overflowing greed, what the HELL is going on with those folks from Bioenno?
It is VERY IMPORTANT to place the fuse as close as possible to the power source, especially in mobile installations. One of it's primary purposes, except to protect the radio, is to prevent a short circuit of the power lead from causing a FIRE, especially where the wiring comes through the firewall into the vehicle, which brings up another topic, the wires should be protected where they pass through the firewall with a rubber grommet or protection sleeve.

I transmitted with 50w or less, and the battery lasted a very long time, longer after I attached a solar panel and charge controller. I now have a kind of semi-permanent shack (literally, a shack in an olive grove) and power my devices 100% with batteries and PV. I would like to be able to transmit with a full 100w, but the LiFePO4 battery says, " no can do." That has to do with the battery chemistry and construction. So now I have go buy a more suitable battery that will deliver constant 20-25A, which means in general a bigger, more expensive battery. My XYL is not amused. So keep the constant output current in mind when you buy a battery. If you want 100w RF output, you will be dissatified with a battery like mine. 73!
Hello Tim, my batteries from "Eremit" create 100 W on the TRX. With 18 Ah, 50 Ah and more. With built-in BMS. Arthur von Funkwelle's TH-cam channel is also testing this on the FTDX 101. That works with it, 73 Jürgen DK4BU

Great video thank you
One of the best upgrades I did for my car battery. Get a automotive AGM battery, I got mine from autozone there Platinum series. Thy take deap discharge better and the on time is longer when the motor is off. The voltage sag is less when starting the motor. The one in my van is going on 7 years and still strong. Just replaced the battery in my other vehicle the one.
Nicely done Josh! 73 de K1JHS
Best noise free power supply, 200 amp hours of battery that is not charging while you're using your radio. Good luck hauling that around with you.
Thank you
Sure thing!
2:42 WoW 21 to 30 Amp at 100 volts is 2,100 to 3,000 watts. At just under a dollar a watt (August 2024 U.S.), that battery (Jackery, Bluetti, EcoFlow) just got real expensive for just one hour of use. I was thinking the Jackery 300 I use to power my CPAP machine would be enough, not even close !
Team Replay for the win!♡♡♡ appreciate your work hamFam :)
This seem to be all quite expensive and complex gear. Do you have simple solution for simple hand held radio's. For example, solar charging a simple usb power bank, and use that at night to charge your recharge the hand held radio's? I do not plan on continuously transmitting with 100's of watts in a grid down situation, just with local living family members / friends. (Even The light saver max is already 400$)
Sure the usb dc cables I mentioned will do that. Just find the for your radio.
@@HamRadioCrashCourse I somehow missed that part - I found the right cable for my plan, thanks!
thanks Mike fantastic video 73 from kb2uew
I’m Josh. 😵
I run my equipment off of the energy produced by my 15 month old. Tough to convert and sometimes has spotty output. 2/10 would not recommend.
Wow, thank you for the nice gut chuckle, I needed that!
Most of the energy produced by 15 month olds is wasted coming out the top and bottom.
In the movie the matrix they have it all figured out, maybe watch that for inspiration.
How is that DMX-40 working out for you?
A video is coming soon!
What is a QRP radio?
QRP is lower power transmitter usually under 5-10 watts.
For remote work, I like Bioenno and Jackery.
Me too!
Instead of making these radios where a power supply is needed, why doesnt ICOM, Yaesu and Kenwood make their radios with regular plugs that can be plugged up into a regular wall socket in the home? How hard can it be to make a radio that plugs up into a wall?
You want them to include a ac/dc power transformer in the radio body to make it heavier and more expensive? What about the people that only have 12 volt dc in their shack or off grid setup?
@@HamRadioCrashCourse Paying a little extra for shipping would not be more expensive than going out and buying a power supply. No where near as expensive as getting a power supply. Even the cheapest power supply for your average ham radio is about 4100.00. There is not way that shipping would be $100.00 more if they included an AC/DC power transformer in the radio. No way.
@@HamRadioCrashCourse As far as off the grid setup, they can still make the make radios that have the all all connections in one radio including a plug.
Companies don’t want to make two radio models one with a different case and power supply and one without. It’s not worth the effort and costs.
Further, power supplies usually power more than a radio in the shack. So that’s an issue.
If the supply fails, a cheap part, do you ship the whole radio back?
FYI, this was tried in the ham radio market. The customer base didn’t want it.
Great video Josh. PS luv the shirt 👍
Hello everybody, I would like to get my L1 and L2 Ham license. My intention is simple, monitor for what is stirring in the weeds and in the event of an emergency be able to transmit. I have a limited budget, so I don't qualify for an enthusiast or hobbyist. What ham at home radio can I buy, so I can use the L1 and L2 online courses to get my license?
-Regards,
-G
Which country are you in? I am not familiar with L1 & L2 here in the states.
@@HamRadioCrashCourse Bastrop TX USA :) HamRadioPrep is how they label the Technician and Technician + General license classes. Do you know of HamRadioPrep?
@@HamRadioCrashCourse I currently own a very entry level ham (BAOFENG GT-5R Dual Band Two Way Radio 144-148/420-450MHz) will this be enough to take the classes and pass the exams?
Good video Josh👍❗️ 73. KV5P
Thank you!!
My goodness man! How many radios do you have? What is your electric bill every month?!
Electric bill = yes
@HamRadioCrashCourse, @Josh... Being a noob to Ham radio I caught wind of something the other day that I was hoping you could clear up for myself and others who may hear the same thing at some point...... Can a person use a CB 'Linear Amp' for Ham radio?..... I have tried to look this question up here on the web, but I'm just not having any luck. Personally I kind of feel the person who told me was being a douchebag and hoping I would fry something so they could be entertained at my expense. I am currently studying to get my license and hope to take my test soon. Thanks my friend, love your content!! Keep up the good work and hope to hear back from you!
You might be able to use a CB amp in 12 or the 10 meter band. You might need to adjust the amp.
You can figure out how much your cigar lighter delivers is to simply find the fuse and check its value.
The connector is rated at 10 A max anyway. Fine for that 2M mobile.
Ohhhh, i need a power Suply or batterie for my radio? First time here about it..........
It depends on the radio. What are you running?
I am a 27 year old women am i the only young women my age that is licensed and loves ham radio ham radio is basically my life i really live for this hobby
Glad you’re out there on the air!
Yes, a while ago, I had a local two way radio
dealer, install a cable from the battery 🔋 to
the passenger compartment with the appropriate connector to match my mobile
radio, which will not perform well on below
the required voltage, such as a portable
battery 🔋. 73 de W2CH, Ray
That IC705 is pretty cute. I'm just not leaving the house due to pandemic, so can't really rationalize it.
Fuses do not protect the radio at all.. What they do protect is the cable itself. The fuse burns out before the cable catches fire.
… which protects the radio too?
such a hassle to find the power supply from your link, you should have a direct link to item.your loosing out money, jut easier to input name of item on amazon,.just saying
If you are running power from your mobile battery and place a properly sized fuse in line at the battery connection you will never have a burned wire, because, a fuse is there to protect the wire, not your appliance...... radio or equipment!
A suggestion: you sometimes say "amperage" and other times say "current" and
that can be confusing to a beginner. "current" is really the correct term.
This is a good point and I’ll try to remember the correct terms. 👍
Also, sometimes people say "wattage" instead of power.
I use old socks... the stinkier the better! I used to use my old lady's worn knickers, but the voltage was too high. Nasty!
I **REALLYYYYY** wish someone would make an HT that would charge directly off of USB-A/C... cmon... Everything is made that way. I've used some USB-A to DC adapters but they are all noisy. I want a damn USB jack directly on the radio.
Radioddity GS-5B has a charging port on the back of the battery that connects to USB.
Yes there are batteries like this, but they don’t recommended charging it while the radio is running.
@@HamRadioCrashCourse Good point, but that's what you get when you charge a 7.4v battery over a 5v USB port.
Solution: have multiple batteries. Continue operating while charging off USB.
Or do what the rest of us do and get an HT with a 12v charger. I was just pointing out that USB charging exists for an HT.
for some reason that is apparently beyond me, those Bioenno bastards charge far more than they need to for their gosh-darn batteries compared to almost any other brand that I've researched............. Apart from overflowing greed, what the HELL is going on with those folks from Bioenno?
Different cells, different BMS, etc.
👍👍👍
I thought for sure this was going to be a jackery ad, it seems they send portable power units to every TH-camr these days.
They might do that. But I bought mine and the panel. 😬💸
Meh, you don’t buy a refrigerator that needs a power supply, ham radio companies are just cheating out
Not really. It’s all 12 volt systems.
