Update on my cabinet of LiFePO4 batteries, how they have been working and when you can buy some yourself.
I bought these batteries from Signature Solar and they are awesome! I've been running my house off grid with them for 2 months 24/7. There have been zero issues. They just work perfect.
Update: There is no longer a discount code available.
In this video I test how well the load is balanced between the batteries. I check the amps going into each from the bus bars. I find they are sharing the load within 1.5% of each other, which is great.
Previous videos about the battery:

Cabinet stacking: youtu.be/89MyA7zPdYI
This is all part of my overall goal to be energy independent. I'm trying to power my whole house and garage off the grid. And this is with an all electric home. That includes cooking and heating. Join me for learning with me along the way. Right now I'm confident I can survive a power outage, or black out. But I'm still shy of being completely off grid.
