Thanks Gill for the great introduction to battery types and their charging units =) YES .... Julian's battery pack is GREAT DESIGN .... with many ways to charge the batteries he uses =)

I have that same Gel cell. Though, now I switched to Bioenno just 2 days ago, with Solar powered.

Nice. I am constantly looking for better, smaller, and easier to charge with a small solar panel. Thanks for sharing.

[AusProbiz]

Hilarious! Got dizzy as you went around the roundabout. Thanks for another great and entertaining video.

[survivalcomms]

Excellent video. I have focused on the 18650 as well for a platform. Thanks for sharing !

Big fan of the 18650 lithium batteries. A great tool to have is the Chinese boost or buck converters or even a boost buck converter that can go either up or down in voltage. Typically 80 to 90 percent efficient. Add a small digital voltmeter and you can do anything from charging batteries from solar cells (cheap and ultralight charge controller) to charging batteries from other batteries et cetera... just adjust the output voltage to the terminal voltage you want and size a solar panel that won't exceed the charge rate of the battery and you're good to go. It's a very flexible solution. If you need 10 volts to charge your Baofeng radio then adjust the voltage converter to 10 volts.

For bugging in I have a 20 watt solar panel mounted to the side of my small antenna mast and a Chinese charge controller charges a 12 volt 10 amp hour lithium battery with a built-in charge balancer and charge controller. These are sold on Amazon and eBay as replacements for sealed lead acid batteries and of course they weigh about a quarter as much. US $80 for 12V at 10AHr LiFePO4 with integral battery management system to balance the cells and disconnect the battery to prevent under voltage (discharging) or over voltage (charging).

Many thanks for that Gil enjoyed the views of your town. My go to power for portable use is the QRP Ranger by Hardened Power Systems. Particularly like the built in charge controller enabling a solar panel to be connected direct. For lightweight stuff I have been using a Tracer Lithium Polymer Power Pack which also works well. Thanks again Larry.

Thank You. Better to have more than you need than less.

Great video. What about a regular high-capacity 5V power bank with a step-up DC-DC transformer to reach 12V? Sure the output current isn't terribly high, but it should suffice for most QRP transceivers. It's less hassle to charge, they're cheap and easy to find.

18650 cells give a good amperage for there size but check cells under voltage when in use as first they get hot then should the voltage get below, , they do go with a good explosion be warned

So I’ll take a look at 1860 type batteries for my KX3. I have a 5 Ah sealed lead acid and that’s too heavy for SOTA. Rechargeable AA type batteries I just don’t seem to get on that well with when operating. Thanks for all the tips. 73 M0AZE Mike

I use Yuasa 12v standby batteries with a 1500, (peak 3000 watt) Inverter with three USB sockets & two mains power sockets.
A 30amp solar panel & control box is on the way for recharging

**This is all for home use, of course!

[konradritter]

Our DV-Repeater (to be build) and our APRS-Digipeater(In Operation) are both 100% solar powered and buffered by huge lead batteries. It's something :)
Thanks for the Video.

[davequick]

Not too long.... lots of good info.... thanks!

[prestonshute]

Very good points about batteries. How much weight are you willing to carry. The AA cell you showed are similar to the pack in the KX2 and you can DIY your own.
My IC-703+ will draw 300ma at 9.6v while squelched, 450ma at max audio and 1.2 amps at 13.8. So what you take to the field will to dictate what power system will work for you.

Enjoyed the first part of your video, always love to see new places.

Hope to meet you on the air some day.

My main QRP field radio is the 817ND and as funds are tight I don't see an upgrade coming along any time soon. I usually carry x3 lipo's at the moment (4500mah) and never discharge below 3v per cell, and was thinking about the 18650 route. I also carry a 45w folding solar panel with a solar controller which allows me to charge while operating. In your video you suggest using x6 18650 for an 817, how would this be configured? Many Thanks

[darrinpearce]

Great informative video. Loved the steering wheel camera!!. By the way, that wasn't a big spider, come down here to VK to see big spiders ;) 73's

[whittierwatts]

Is that somewhere around South Georgia at 8:30?

[tygriffin]

Another great video. I really enjoy your LNR mountain topper CW vids. Thinking of batteries, I've been wondering about using an external phone charging battery by splicing a couple usb out into a standard barrel plug. I'm not sure this would work but would be handy if it did.

[joeframo]

Hey radio prepper turn your mic gain up you're already a little bit so we can hear you better anyway thank you for sharing great great video
