For example. I have a 48v powerwall home system. From there, I use a 48vdc to 12vdc step-down converter. There are lots of different...

Triple check polarity. This can happen when the battery is connected to the controller incorrectly

Couldn't pass up a deal on a roller posted to my local classifieds. It was an old Ninja, rough shape cosmetically, but structurally...

You'll want to check the back of a solar panel for the label that lists all the power specs. 12V nominal is just that, "nominal," in...

Love this.

Recently discussed in a previous thread...

IMO, capacity, then self discharge, then IR.

I wholeheartedly agree, but OP is choosing not to do capacity testing, so there won't be any way of knowing which are the weakest cells...

Ok, but my recommendation is to continue the full charge to 4.2v (they are Li-Ion, right?) at that continued lower amperage. Not just up...

I don't, sorry. I make squares.

Phew. It would be exactly my kind of mistake to order squared holders and offset busbars.

This doesn't answer your question, but it looks like you have squared cell holders, but offset busbars. Is that correct?

Balance them before you assemble. Then they'll be identical voltage and it won't matter what order they're in. I'm not the first to...

Hopefully I speak for others as well as myself when I say that Amberwolf's contributions to the forum are priceless. However, I have...

It's not. Do me a favor. Pick one of your cells. Doesn't matter which one. Record it's voltage. Charge it for an hour at a safe...
