It's funny how complex things seem as a beginner. I hope I can look back at this post 1 or 2 years from now and laugh at how clueless I was when writing.
I was over-eager. I couldn't see past the $0.13/kWh pricetag.... and now I have 16.5 kW of LiFePO4 power. You'd think I'd be happy, right? Wrong!
Each pack has 56 cells at 3.7V and 10AH. I checked the voltage prior to purchase and 6 were 12.28V, one was 16.09V and the last consisted of 56 cells and no busbar to check.
However, this is the least of my problems it seems. I'm in the market for a Sol-Ark 12k and need these batteries to flow at 48V...
I'm of the understanding that I can charge these batteries up and reach their rated 16V which means it'll take 3 to reach 48V... which means I'm looking at 168 cells to strap to a BMS and top balance... Am I right? If not, I'm looking at 4 packs and a 224 cell BMS... I just hope I'm wrong.
Questions:
1) I took for granted that the Voltage should increase once the battery is recharged... is this true?
2) I don't think even an Orion BMS can manage 168 cells right? Even if it could, they're going for $400 plus. Not really a reasonable option from my point of view. So... is it possible to purchase multiple cheap BMSs to accomplish this goal?
I'm just a tad over my head, I'd be grateful if one of ya'll can lend me your brain for a few to sort this out.
Thanks!
