This paper is aimed to develop a voltage equalization circuit for lithium iron phosphate batteries
LFP (Lithium Ferrophosphate or Lithium Iron Phosphate) is currently our favorite battery for several reasons. They are many times lighter than lead acid batteries and last much longer with an expected life of over 3000 cycles (8+ years). Initial cost has dropped to the point that most of our LFP battery banks break even with lead acid cost after only 4 years. In some
