As soon as I pressed the 'publish' button, I realised that I'd made a mistake. When I said "75A output" I meant "75V panel voltage". Sorry for the confusion.
I was offered some second-hand LiitoKala Lii-50A 26650 5000mAh cells and some of them didn't have the best start in life. I salvaged 120 of them to make a 2.5kWh solar battery bank. I designed and 3D printed the holders and it's all working perfectly!
