How do you like the Orion? Do you find 18A max charge is enough for your use?
Super nice job on the install.
Sorry if this is a repeat question, but which cells are those and where'd you get them?
This kind of Fortune 100ah LiFePO4 Battery cell has holders and plastic covers, you can connect each battery cells easily and the gap between each battery cell is well controlled to help the battery heat dissipationView attachment 2717823View attachment 2717824
The fortune cells are nice from what I've seen online, but they're considerably more expensive per cell. I built one on the cheap as an experiment and bought all 4 100ah cells for about the price of a single fortune cell. They weren't grade A, but that wasn't what I needed. I'd love to get some for my next project.
The fortune cells I used from overkill solar were $155 each. Alibaba shows EVE LF105 for about $70 each. Where and how cheap did you get your cells?
I purchased 4 100ah Littokala cells off AliExpress for $170. These were clearly not grade a cells. As I said, these were basically just an experiment for a bigger system in the future. I'll probably get some 280ah cells from a reputable distributor at some point in the future.
Free shipping. Batteries were $166, with tax $180.Shipped? If so that's a great price. I paid about double that for mine, but the seller was local and I was able to test them first.
