It’s all aliexpress. Liitokala batteries and the BMS just looked nice

Yes, it is quite heavy. Not for light trekking.

Yes a 32Ah 4s lifepo4. Fantastic battery. I can run full power for hours

I have a master switch on the power cable before the fuses even. I lost a couple of expensive lipo batteries when I forgot to disconnect them and put the radios away for a few months.

I was looking into that. Good idea.

I looked at the spec sheet and it seems that just taping the cells together like that should provide necessary support for all but the outer sides.

A clamp wouldn’t hurt, but probably give me negligible benefits in the projected lifetime of this pack. I’m not using this very often so the pack will age out before charge wear will be an issue. Say I get 300 charge cycles over 10 years, that would be heavy use for my radio pack.

See that black lid? I think it can just about hold 6 cans.

Thanks. Got to make a clamp for the batteries then.

Didn’t have N connectors. They’re so fiddly to solder. And rg58 is what I have so that is what I use.

It’s an IC7000, so it can do 100w on HF. I will use various antennas. But all of them built from bits and pieces in the garage. Mostly eflw, dipols or verticals I think.

13.8v is the charging voltage of lead acid batteries. So it stuck.

That’s a ic-7000 and it does 100w out on hf.
