I heat copper pipes in the woodstove, flatten/shape them with a hammer and then drill. They soften/anneal quite a bit even before...

Worked with copper in my blacksmith shop to make ornamental items and even after a short period of hammering on copper would go back to...

Copper will go soft to bend if you heat it to near red color and quinch in water, it will work harden if bent cold.

What is the best way to connect the battery positive and battery negative terminals (BC0 and BC8) on the cells to the BMS and the + bus...

I think your thoughts are theoretically correct, and in a high-C use, maybe significant. In my case, my load on 3P 300A cells will be...

Solid busbars have worked fine for me on an RV build, but I'd be hesitant to use them on a boat build. Much more three axis movement...

I used 1/2 inch copper L pipe which worked wonderful for me. It is very easy to cut with a pipe cutter. It works well at currents of 100...

I read through this thread: https://diysolarforum.com/threads/custom-bus-bars-from-copper-flat-bar.33832/ But my situation is a little...

Fwiw I just squeezed a 58V wire, hard with a dry hand to verify that I couldn't feel any kind of shock, so just as easy to work on as 24V.

I love my 24V system too…chose it for several reasons… wouldn’t change a thing except I’m adding more panels now ..all else does will do...

Going over 33 volts means your system falls under a different set of regulations in some places ( maybe not in some or all of the USA )...

+1 My 12v is also flawless and works perfectly. 24/48 would just add complications I don't want and don't need.

Considering the cost, warranty and features on most packs available now, it's hard to resist plug n play packs. I just gave away my...

192lbs just cells, bus bars and BMS.

I’m more comfortable with the reliability and safety of my DIY batteries. I recently commented in another post that commercially made...

Right! That is a lot of power for cheap. I dont understand why this is even a question. An hour of my time is certainly work $400...

16s 280 ah is 13 kWh a Tesla power wall, or almost 3 of my 5.1 kWh fortress power flex 5.1 kWh

How can imbalance kill cells? If a cell isnt going past its HVC and LVC what difference could it make to the rest of the cells? Or are...

My guess is the imbalance allowed a few cells to sit at hvd, and stragglers didnt get charged, then eventually they took on less and...

The last set of purchased batteries i bought came poorly balanced. They reached 100Ah, so i went with them, but the balance must be set...
