KX2 - external power

The first thing I did to all my batteries was chop off the connector and fit an inline fuse and a pair of powerpoles… instantly invalidated any guarantee, but thankfukly never had any problems.

I was initially sceptical about the value of powerpoles, but they’ve served me well over the years. As I’m mean, I prefer to solder mine so they can be reused. The key thing is to have a non- reversible connection system to avoid accidents on the hills..The XT60 certainly fits the bill… but don’t forget the fuse!

Cheers. I have fuses inline for the FT-857. Just ordered some for the KX2 as I have no spares.

John - I have been using 10 X AA 2500mA NiMH rechargeable packs for 15+ years.

I charge them as a ‘single pack’ using a current of around CAPACITY/10 mA. My simple homebrew charging circuit is shown below.

YMMV

Thanks Dave

Would you like to elaborate on the fuse Gerald? What fuse in particular did you use, do you use an enclosure/fuse-holder or do you just solder it directly on the wire?

I have used an inline glass fuse holder like

I use these type:

They use the same fuses as my car. I bought a box of 100 assorted blade fuses some of which are used in radio cables and the rest were split into 2 groups and placed in my car and my wife’s car as spares.

It’s well known electrics fact that if you have spare fuses with you, you will never have a fuse fail. They only fail when you have no spare!

Don’t forget to fuse both positive and negative leads.

Standard 30mm glass fuses in inline holders.

Nothing complex. I removed the connector from the original wires from the battery and soldered on extensions terminated in powerpoles with an inline fuse holder in the positive lead.

I changed to using “Poly” (aka PTC) fuses (self-resetting fuses) after hitting exactly the problem of not having a replacement fuse to fit kind of holder I had used, while on a summit.
