My AGM to Lithium conversion

When I first posted on this thread it was all 80/20 or 90/10 talk compared too...I simply mentioned why not use 100% as most manufacturer batteries have a cycle count for..Some people may choose to use it all or very close to it without harm...If a user needs 102ah,it's there for use without worry whether he trips the LVD or not... . . . .

These numbers are loosely based on a lifepo4 cell manufacturer's spec sheet I saw a few weeks ago. More to show cause and effect relationships than anything else.

Cycle life defined as number of xx - xx% SOC cycles a cell/battery can sustain before the ah capacity drops to 80% of its original rated capacity.

30-50% = 10,000 cycle life
20-80% = 5,000 cycle life
10-90% = 4,000 cycle life
0-100% = 3,000 cycle life

Another factor in cycle life is charge and discharge c rate. Go high, cycle life goes down. Go low, cycle life goes up.

Exposing the battery/cells to excessively cold or hot temperatures while operating at higher c rates will also reduce cycle life. Ideal temp is 75-77f.

Using a lifepo4 battery/cell, in any way, reduces its cycle life.

Pick your poison--lol!
