[Elecraft] Batteries for NPOTA Activation with KX3
Hi, I'm planning an NPOTA activation using my KX3 on SSB and CW, running max output without an amplifier. My antenna will be an inverted V at 30', and I'd like recommendations for a battery technology and brand, assuming I don't use the internal batteries (I think I would rather not). I'm looking for something that will work with a KX3 as well as an IC-706 MKIIG. Ideally, I'd like to get several hours out of it if possible, but I do know that that's hard to say based on number of contacts and SSB/CW. What's the best method of making a connection from said batteries to the KX3? I suppose powerpoles to the standard KX3 connector would be idieal Anyway, thanks so much!

Re: [Elecraft] Batteries and solar power
Hello Jack I can see your experience is good. I haven't so far uncovered what is meant by life for these batteries, perhaps it's when the energy being fed in is more than double what is taken out or something of the kind, or the time it takes to drain to a projected cut-off. I doubt that the internal resistance is measured. As an ex marine operator, standby (emergency) battery life was very important and they were replaced on a strict schedule, however good or bad they might be in use - a bit like alarm batteries and such like.

Re: [Elecraft] Batteries and solar power
My 2.5 centavos worth - I've been running my station (couple years with an IC-756 Pro III, and three+ years a K3/100) on three Sun-Xtender PV-1040T AGM batteries connected in parallel. They are 104 AH each, so I've got about 300+ AH to run my equipment. These three batteries are connected to a ProStar 15M charge controller, which is also hooked to a single 72-watt G.E. solar panel. These three batteries have ample power to run my K3 at full power (along with a KAT500 auto tuner) for hours on end, along with a 12v station desk lamp. The batteries are at least 6-7 years old and appear to be holding their own. I have them connected to an N8XJK boost regulator, which provides me with a full-time supply of 14 volts into a RigRunner 4008 power distribution module. In addition to the K3, I have a home-brew 80 watt, all-mode, 2 meter linear amplifier running from the same supply to give my K3's 2 meter RF a little punch. My K3 has never been connected to the power company mains - 100% solar / battery. Now , my KPA500 amplifier - that's a different story!

[Elecraft] Batteries and solar power
Rather than lithium ion I'd use AGM batteries. I had four of them in my motor home for about 8 years when I was on the road fulltime. They cost about twice as much as a flooded lead acid but are safe enough to ship by air etc. they last a long time, and are perfect for a green solution. I charged mine with 350 watts do solar panels on my RV and could boondocked for several weeks without running my Genset. AGMs make a great addition to a shack. They can live inside your house without worry and you have none of the problems associated with lithium ion. My k3 ran just fine off of my solar panels, AGMs and inverter when I was on the road.

Unlike some of the Chinese NiMH batteries that offer over the top mAh ratings these truely are 2850 mAh. I have no connection with the Ansmann company but check it out for yourself the reviews, the cost is 20.00 for a pack of 4 but from what I have seen they are well worth the $$.

[Elecraft] Batteries and transmitters on aircraft
I may be mistaken but I thought I saw a recent posting (or two) saying that batteries could only be transported in carry-on luggage, and that transmitters were not permitted in carry-on. I’m planning a trip to Little Cayman next month and will be taking my KX-1 (yes, I did get the necessary Radio Apparatus Importation Certificate from the Cayman gov’t). When I travel I take the KX-1 in my carry-on. But I have a large diving light with rechargeable battery (NOT Lithium) that goes in my checked baggage, with the battery connector unplugged so it can’t turn on accidentally – in addition for using the light for night dives, I use the battery for 12V power to the KX-1. I’ve just pored over the restrictions on the TSA website and could find no prohibitions against what I plan to do. The TSA site says check FAA for any other restrictions. If you click on prohibited items on the FAA site, it links you back to the same TSA list. There is, however, a separate PDF on the FAA site on batteries, and this, too, doesn’t seem to prohibit what I’m doing. There are restrictions on Lithium batteries but that’s not what I’m taking.

Re: [Elecraft] Batteries and transmitters on aircraft
I just flew from Detroit to Austin last night with my HT in my carry-on laptop bag, batteries and all. I also had a spare in my checked luggage. Not a peep from anyone at the airport(s). Not a definitive answer, just a sample of one...

I’m planning a trip to Little Cayman next month and will be taking my KX-1 (yes, I did get the necessary Radio Apparatus Importation Certificate from the Cayman gov’t). When I travel I take the KX-1 in my carry-on. But I have a large diving light with rechargeable battery (NOT Lithium) that goes in my checked baggage, with the battery connector unplugged so it can’t turn on accidentally – in addition for using the light for night dives, I use the battery for 12V power to the KX-1. I’ve just pored over the restrictions on the TSA website and could find no prohibitions against what I plan to do. The TSA site says check FAA for any other restrictions. If you click on prohibited items on the FAA site, it links you back to the same TSA list. There is, however, a separate PDF on the FAA site on batteries, and this, too, doesn’t seem to prohibit what I’m doing. There are restrictions on Lithium batteries but that’s not what I’m taking.

[Elecraft] Batteries for K1.
Hello all, I have a lovely K1 and I am about to start my SOTA activitions, maybe next saturday. My K1 has a KBT1 an Internal battery Adapter and I have 4 rechargeable batteries at my own. What could be better, buy more rechargeable batteries or a small battery, however bigger than AA batteries, to operate with ? Any answer will be welcome here. Best 73 to all.

Re: [Elecraft] Batteries
I suspect that no matter what type of batteries that you have, they would die as soon as you press the transmit button. Pen cell batteries are not designed for the current required to transmit. As for your cells, they are probably either NiCad or NiMH cells. They can be charged with the same smart charger. Trickle charging them is not a good idea. You need the charger to turn off when the cells are fully charged. You certainly can connect the cells in series to get a higher voltage. Connecting this type cells in parallel without diodes to protect one set from discharging into the other is not generally recommended. I put batteries radio control into garden railroad trains and I never connect 2 battery packs in parallel without diodes. If you really want to run your radio from batteries, either get some gell-cells batteries or a set of good, high current NiCad, NiMH or litium batteries. I have bought NiMH D cells with a rating of 10A/H. They will deliver over 30 amps. Your pen cells are probably 2A/H and will only do that at low currents since their internal resistance is relatively high. __ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html
[Elecraft] Batteries, batteries, batteries
My brother-in-law just gave me a large box containing literally hundreds of what he says are recharageable batteries. That is all he knows about them. They are in sets of three in series, AAA size, with solderable tabs. I suspect they are nicads, but don't know. NOTHING is written on them. They are green, for all that means. Can anyone guess what they might be or suggest a way to find out? Could I put them in series/parallel to make a battery pack for my K2? Does anyone want some? Or should I be looking for a way to dispose of them (I'm sure they count as hazardous waste)? -- Vic, K2VCO Fresno CA http://www.qsl.net/k2vco/ __ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html

Re: [Elecraft] Batteries, batteries, batteries
If they have solderable tabs they are most likely indeed rechargeable. I can't think of very many applications for single-use alkalines with solderable tabs. To check them out, the best bet would be to try to charge them with a small DC supply and a current limiting resistor to hold the current to maybe 50 ma, and then see how they hold up under a similar load like a flashlight bulb. Nicads can degrade even with lack of use so don't be surprised if the results are disappointing unless the batteries are relatively new. Dave AB7E On 4/5/2011 12:58 PM, R.

Oh go ahead and get the flooded cells. The weight is spread over six individual cells and the weight is under a hundred pounds per cell. That way you can have quite a few cloudy days without concern. I have six stacked on the floor against the wall under my operating table. Solar backup would be a great way to go. Unfortunately the K3 draws a LOT of power just on receive.
