Sorry, the configuration is one 3-long string of 2 cells in parallel (not 2 parallel strings).
I dug deeper into the reviews. People say there is indeed a built-in charge balancing in the Aili powerbank.
The pairs of cells still must be closely matched, but this is true for all other powerbanks where cells are connected in parallel. I am using cells from old 3S2P laptop batteries, where cell pairs are already welded together.

Re: Iambic mode - A or B?
I use a palm radio pico paddle attached to the underside of the FT817 when doing on the air cw. But i go on VBAND website to practice a lot, and for that i detach the key from the radio connect it to the phone with a circuit and just hold it with the left hand while sending with the right hand. Bottom line being i think anything is possible as long as you get used to it. The paddle in hand thing works for me with the pico paddle because its small and light. with a regular sized paddle other will probably not be practical.
?
I like paddles for the practicality and because you can’t send badly spaced/timed characters, that helps to build good “mental timing”. And i got used to “squeezing” sending some letters using both sides of the paddle simultaneously.?
But I haven't been doing CW for as long as you.

Thanks every one. Think Ebay will do the
job.
Appreciate it.

Just looked on Ebay. Mostly the battery-plate-charger kits. Or same kit with the plastic stand. I've had good luck with the Windcamps (have 2 FT-817ND's) 73, Rich W1GBB

Kevin for the reply. I am trying to find someone that just sells
the battery alone. Not the charger or battery plate. I already

Re: Iambic mode - A or B?
Thank you for the quick reply, Bruno. I've used a Vibroplex semi-automatic key and a Lionel (I still have that) so I'm used to dits with the thumb and dahs with the index finger. In this case, though, I'm using the left hand and still have dits?with the thumb, dahs with the finger but of course they are on the opposite sides. I was told by my mentor (50+ years ago) that using a fully automatic key would ruin my fist, so I'm using the other hand.?
Rightly or wrongly, I've mounted my tiny stainless twin-paddle key on a box with knee straps. The box contains a PIC, a lithium cell and a 2.4GHz transmitter to make it cordless. I wonder whether this makes iambic keying more difficult because the key can twist slightly on the straps. I've tried turning the box around so the paddles are pointing away from me and my hand rests on the box to steady it, but the box has a sharp edge which needs to be padded.?
I might try a single paddle and forgo the iambic mode, or make? a sideswiper. I've never used one of those.
Thanks again and 73,
John G4EDX
Hi John
It’s a matter of preference, i would risk saying that Iambic B is the only mode on the FT817 and also risk saying that it is the most common mode to be using a paddle. The main difference is how it handles “squeeze” that is maintaining the dash paddle held down and insert a dit on the right timing.?
?
Also if you are new to paddle use, i would also recommend dash on the right dit on the left. You can learn either way and there is no right way but it’s what most people use.
?
hope that helped.

A hint about the battery you have would go a long way in getting feedback comparing the physical size of your battery to that of the windcamp battery...

I recently ordered a Wind Camp Battery plate. Seems the battery I have is too large for the plate.?? Dumb question, is the Wind Camp Battery that much small than the battery I? have? I assume so?

As a long-term straight key operator trying to get to grips with iambic keying I would like to know whether the 817's internal keyer is mode A or mode B. Whichever it is, there isn't a choice, and I'm convinced that I would find the other mode easier!?
Any advice, please?

Good morning to the group, take a look at the following site ,? has an excellent tutorial on aprs using direwolf on raspberry Pi using the digirig.

That sounds like a really bad design. The cells do not stay matched and how do you match capacity? Any proper charger for multiple series LiIon cells needs a controller than measures each cell.

Or search for "aili 18650 powerbank".
This is the kind that satisfies the requirements. I haven't tested it for EMI with my FT-817 yet. Using it as an extra power for laptops.
It can charge from a 19V laptop power adapter with 5.5x2.1mm barrel tip and can output 5/6/9/12/15/19V selectable by mechanical switches on its 5.5x2.1mm socket. Has a USB-A output for the phone as well.
The best part for field operation is that you can replace 18650 cells with ones pre-charged at home, so essentially "unlimited" capacity.
