My LADDA cells arrived today and you're right about them being oversize. I'm not happy trying to force them into the tray so I will use them to make an external pack and charge it with an airsoft

I took a good tooth pick with a very small amount of "Crazy Glue" on the end. I stuck in and after about 1/2 a minute or so, pulled out the tip. 73, Joe, K8JP/K5

I purchased a 817ND recently and it had the same problem. It was stubborn but I was able to pull it with a very fine "dental pick" type of tool. No harm no foul on the sale, but the rig wouldn't power

Thank you Ronan, I had forgotten that the whole cell case apart from the circular bottom plate is positive and I have the LADDAs in there right now. That was a forced option because the '818's battery

The LADDA cells are a tight fit in that plastic tray, right enough, but I've not had any issues with them not making connection. They are pressed quite firmly to the cells in the adjacent rows though

I also have had the experience that many NiMH cells, especially the slow self discharge/pre-charged cells are larger in diameter than their alkaline counterparts and will not fit in some

I'm aware that I wasn't anything like the first, but I flagged up the IKEA Ladda cells some time ago, probably on the groups.io Elecraft KX group and was indirectly rebutted by some foreign

You're right! I found it at the bottom of the box (unused). OK one more question. Is the installed battery pack only charged from an external supply when CHG is selected? Thanks, -- Mike G8GYW

It’s standard issue with the radio. 73….Eric VK2VE. Sent: Tuesday, 1 November 2022 18:34 To: [email protected] Subject: Re: [ft817] Question about replacing the battery Pack

I have done both. The charging circuit in the radio takes an age as it's designed for smaller capacity packs. I have a couple of external 4-cell chargers which do the job much faster. To be honest, I

There was an 8xAA battery tray included with the ft-817 when I bought it second-hand. Not sure where it came from originally.

I've built exactly the same Li Ion battery pack and it works well. I take the cells out to charge them, though. My old FT-817 (not ND) runs full power. That particular BMS board needs to be

Ronan They do indeed look like a good idea especially for the rare /p service I envisage..... Do you charge them with the ft817 or take them out & use an dedicated, branded IKEA charger? 73

I'm Interested in the LADDA cells. How did you connect them together? -- Mike G8GYW

Jacks are 5.5mm x 2.1mm, not 2.5mm, sorry.? But is good pack for QRP rig. 73, ron, n9ee/r Ron Wright, N9EE/RHernando Co ARES EC Spring Hill, Florida also n9ee55@...

I bought 3 of these packs that house 3 x 18650 batteries.? Has two 5.5mm x 2.5mm jacks, one for input for charging and one for output.? Also has a on/off switch and LED indicator.? Has PCB with ICs

Have a look at the LADDA branded 2450 mAh NiMH rechargeable batteries that are sold in IKEA. They're produced in Japan and are excellent quality cells. I bought 8 for the internal battery tray in my

It is sliced already and under 3D printing on my Mk3 Prusa printer…. I will let you know the results. Petr

This shows how to make the internal charger terminate on lithiums. /g/ft817/files/ZL1THH/FT817-BatteryCircuits.pdf Read all the notes on the schematic. Note also that there is a lot

You can manually select full power at any voltage. On HF you can get 5W output at 9V. (At UHF the gain falls off at low voltages) So you can get full power off the NiMH? battery pack. The radio
