I currently have a 48V by 210Ah battery bank (2 banks @ 105Ah each) - Lead Calcium Deep Cycle batteries which I can only safely draw down to 50% DOD. Can I therefore assume that the available current that I effectively have is 105Ah usable power i.e 50% of 210Ah? If my assumption is correct, would the Li-ion equivalent be 5040 KW or due to the DOD of Li-Ion can I go for a lesser battery to achieve the same availability? Your advise would be appreciated.
