I've been mostly tidying up my shop...I'm one messy pup when I get working on things. It was something to do while keeping an eye on charging batteries and staying in out of the cold...

I cooked the 24v SLA charger I was using, somehow. It survived charging the ebike batteries (though it required adding a bunch of resistance to slow it down and not overload it), and then went out on something else in spite of all the resistance I had in to slow it down. Go figure?

Took it apart this morn. Not the first charger like this I've "cooked". Found what I was looking for pretty quick...





That was a 1 ohm resistor. Seeing as I had bought two when I fixed the other charger, I still had one hanging around. Easy fix.

Adjusted the output voltage as well. It was too low for my liking...



Might help keep the batteries healthier. Probably wishful thinking. But hey, while I was in there, why not?

I shouldn't be frying any more, seeing as I rediscovered my programmable power supply. It can give me exactly the voltage and current I want to output to a battery of just about any voltage.
