DIY your own Batteries!!!
I made my own DIY battery and it saved me over $500 compared to the big brands. I wanted a 12 volt, LFP (lithium Iron Phosphate, LiFePO4) battery. There are several brands to choose from such as Battle Born, KiloVault, Victron, Renogy, and more. They are built solid and if you have the money to buy one, they are worth it. Seriously. Battle Born Battery: This is a high-quality manufacturer. If you don’t have the time, tools, or desire to build a battery yourself, then check out Battle Born.
