Sunking Battery Rule # 84

PN thought I would share with a useful battery rule you might find useful. To accurately compare a FLA to LFP we need to find a common denominator between the two types to be equal in application. For RE application the standard is 5 day autonomy using FLA with 50% usable. Let's say a 100 AH FLA battery would have 50 AH usable. So what size LFP is equal to that under the same criteria of maximum cycle life. Well the Answer is:

Sunking's Battery Rule #84

That rule states for every 100 AH of FLA battery takes a 84 AH LFP to be equal or 84%.

If you operate a 84 AH LFP between 80 and 20% DOD or SOC whichever way you want to look at it will equal a 100 AH FLA operated from 100 to 50% SOC. Both have an equal usable 50 AH.
