(R) 40152S headway cells

These LFP 15Ah 3C high capacity cells with m6 screw terminals are popular for their ease of use and assembly. If you plan on reconfiguring your pack every few years, this is your best friend. The cells listed have been thoroughly tested and are of high quality. 

The cells consistently test at 16Ah despite being labeled as 15Ah.

(R) disclaimer: We are aware of the issues that have plagued headway as they sent bad stock to North America in the form of 8% (1/12 to be exact) of each batch shipped being problematic. We ourselves were affected by this shady practice, but we have already sorted and removed affected cells. Althought these cells have only gone through a few test cycles, they are older and so we have marked and priced them as repurposed.
