    wonderful battery purchase with Excellent packaging!!

    order enough eve 280Ah cells for another 24v pack from @Amy Zheng and the packaging was fantastic!!!

These are duracell deep cycle 6v 215Ah golf cart batteries, I have four in series. I have been working on getting a lifepo4 battery bank to replace them but the wait/delays...

    daly smart BMS balancing is a mystery novel, has anyone solved this?

    I have the daly smart bms 8s, 100amp plugged into the computer and the program is showing me what is going on(or so I thought). I was charging the 8S pack at 18amps, cell high voltage set to 3.6, low set to 3.0, balance set to start at 3.5v...all seems well. So I leave it for an hour, come back...

    diy 32650 battery bank pure nickel weld strips

    finally after months of searching I found "real" pure nickel 32650/32700 (4P)spot weld strips. I purchased many 2P and 3P strips from stores on ebay, and aliexpress, everyone that said pure nickel turned out to be, you guessed it, plated steel. (some stores offered refunds when I showed their...
