Ideally you have enough battery capacity that you never push your batteries beyond the manufactures recommendation.
Some types of battery might go a little deeper than others depending on the chemistry.
But the less deeply discharged the better for making your batteries last
For many years we got along pretty good by trying to keep the batteries always charged as possible.
Example of you know you are going to need a lot of DC.
And if you have a delco plant start it before you draw your batteries down.
If you do draw your batteries down charge them asap to reduce large crystal hard sulphate formations that are the killer of batteries.
Some people will want to avoid gasoline powered lighting plants.
I get is you want something that’s wood fueled.
By all means built that! But have a gasoline back up lighting plant too
On hold but not a still born project this will one day be an automatic battery charger.
See the automatic choke?
That’s my special doing, made from Kohler lawnmower parts ( XT-6 series engine )
Stick with a good Chinese Copy of a Honda and you never go wrong.
There will be parts and pieces of these around forever.
Cost of this build to day is about 60 bucks in scrap parts including an old Ford alternator not shown.
The alternator is an old FORD G1 with external regulator.
It can charge or it can also weld as long as you stick with small rods and light duty jobs.
You might even get creative and re power an old flux core with one
Out yard saling with the wife?
This little fellow is an APU off military vehicle from the 40s.
Its a Johnson chore horse generator rated at 300 watts.
But its electric start and frugal in gas.
if your batteries are low and you just need lights for an evening these little lighting plants are still out there to provide you with some AC late at night.
So, off on a ramble there, but you get the message don’t abuse your batteries by deep discharging.
Have a back up ready to provide supplemental power and lighting and your batteries will thank you for it.
You guys may have noticed always a paper bag from the liquor store seems to appear in my photos…
One might think I have a problem ha ha.
No I keep all paper bags and these are all filled with charcoal.
Adding great vid of a DC chorehorse ( mine is AC 120v for a radio )
Not a great welder, but you can stick things…
