Some datasheet that I have seen says that after reaching its max cycle that it will have 80% of its original capacity. And then some articles I have read says that they replace their batteries when the total capacity of the battery is down at 80%.
My question is if it still has 80% of capacity then why do you need to replace it? It still has 80% capacity right? Can't you just parallel a new set of battery bank with its own BMS to offset the lost 20% capacity. So if your original battery bank is 100AH and you add another 100AH then now you have 180AH.
Is the internal resistance too high at that point that you can no longer discharge it at a decent rate?
I would think that you would only discard the batteries once it can no longer hold any charge.
