This morning I wanted to see how my hydro crimper works on 1/0 lugs. I was playing the 1/0 wire and it was more stubborn than my youngest. so I opted to cut 8 strands of 10 awg wires and use a 1/0 lug [all ancor marine grade] and crimped it. I had to tape them tight to keep them even prior to...

Good Morning from Sunny Balmy West Michigan! In a previous thread someone mentioned HP server PS as being a cheap source of mega amps/watts. I will list a few I found that worked with minimal work. The PS alone is not the complete solution, I need a BUCK/BOOST CC CV converter to make use of...

Morning from Sunny Balmy West Michigan, I test my EVE 280ah cells and I got 272ah out of them 4s1p config before I was too sleepy and stopped. I charged them and added back 100ah, I am guessing I am at 110 ah give or take a few amp hours. Is this SOC 110/280 = 40% approx good for storage...

I wanted to send 4 lifepo4 topband cells to my buddy in AZ. Any suggestions on carrier I should use? How should it be packaged?
