We have the Winston 1000Ah cell LFP1000AHC in our showroom for presentation. This high capacity cell was purchased in 3/2013. We checked the health of this cell now and what is the result?
Absolutely great! The capacity is 1240Ah at 100A charging/discharging current and temperature 20°C . It means the cell has 124% of the nominal capacity after 4 years.
