Hello,
I have made a few of cables now for IC7000 to Rigexpert either ACC or rtty and data socket. Rigexpert sell these for ?40 plus postage I
sell mine for ?21 posted uk or ?24 posted to us ($40 all in). Good
quality cables. If anyone would like one or would liked sponsored
one for expeditions etc drop me an email.

Re: [IC-7000] Inexpensive lithium-ion batteries.
Btw, 2000 ma rated 18650 cells are the jelly bean category of the family. Later versions are in the 3000 ma range with Panasonic the leader.? Be aware that there are two types of the cells, protected versus unprotected. ?Basic cells are unprotected and OEM. Protected cells have a small circuit board with a solid state "fuse" that disconnects the cell in the event of over current or under voltage discharge. They are usually added by second tier distributors and make the cell slightly longer. Lithium chemistry require the cells to be used with care. Improper charging or discharge can cause them to heat to the point of ignition. Protected cells are worth the extra cost.

I've dealt with BG many times and they are honest merchants.
The batteries / charger seem to work OK.
I'd be grateful if someone could direct me to a source of the nickel interconnection strap material one uses to construct battery packs.

Re: [IC-7000] Inexpensive lithium-ion batteries.
The strap has to be spot welded as it takes too much heat to solder and you could damage the cells. Check to see if you have a "Batteries R us" type store close to you. ?They can build packs for you and there are numerous sources on the Inlet. You can get battery holders for the 18650 cells that would make pack assembly easy. Google is your friend...

Once the battery voltage on load drops too low then there
will be instability showing up as poor audio quality

If really worried about the drop in power, buy one of the
battery boosters that go in line with the radio power feed
to maintain 13.6 volts at the radio. You can then run your
radio at the full 100 Watts out until the battery is
completely flat. It will also compensate for poor battery
wiring and any other small losses.
Seems to me we are all worrying too much about what
doesn’t matter too much really. It would be nice if the
power out was stable over the full battery voltage range but
it isn’t. Maybe if the manufacturers fitted a battery
booster/ stabiliser within the radio and advertised the full
power out right down to maybe 10.8 volts, then they would
increase their sales.
I simply use the solar panel, which makes my overall power budget
positive and keeps the battery voltage reasonably high during Tx
(not as good as an alternator in a car, but good enough).? I ran the
IC-7000, a TM-G707A and a Macbook Pro (with DC-DC converter) on an
all day public service exercise.

Re: [IC-7000] IC-7000 and SOTA
For field day our club runs a 7000 and ft897 both on two deep cycle batteries with battery savers and change the batteries out twice with two spare sets. That is 3 batteries for each radio. By the way, those batteries also power an inverter each to power a laptop for logging.
Setup is battery saver, radio, inverter, and laptop on one battery x two stations.
Granted those batteries are LARGE but if you had 3 of them with a similar station setup, ?you would have 24 hours at least. And if you had a small generator and charger on the side to recharge the batteries while you are using the other battery, you "technically" are not running on gas power correct?

Well, no, not really. I was thinking of a deep cycle marine and a backup battery for when that ran down. Why do it not play well with a battery? Probably will run the least watts I need, but start with 50.

I've used mine off a battery, both with and without a portable solar
charger (100W panel and regulator).? Certainly with the solar system
guarantees full power, but it runs fine without for a while.

My 7K seems to be happy on a standalone battery for portable use. ?You can't run 100 watts -- but 25 watts is only one S-unit down. Mine will reliably deliver 35 watts TX PO at 10.9 VDC (measured at the radio). ?You really don't want to discharge a deep cycle battery much below that, anyway.
?It's no worse than an FT-857 or IC-706, in my experience -- once you remove icom's deficient fuse holders on the power cord that can drop over one volt at full load.
The drop of TX PO with supply voltage is a function of the PA FET specification primarily and is no different from its competition, in my tests. ?It could be designed to supply 100 watts at 11-15 VDC on HF, with extra cost and heat dissipation, but the battery's charge would plummet rapidly.
Of course the battery has to be sized for the task and well maintained over time, also. ?I use retired 80AH AGM batteries that are cycled out of commercial UPS systems every 3 years.
