A BATTERY MOOCH POST: Samsung 25R (6M Variant) 18650 Bench Test Results…25R5 is slightly better

This 25R6M is a true 20A cell that performs well but not quite as well as the 25R5 variant. The “M” indicates that this cell was made in their Malaysia factory.

I don’t know if all of the 25R6M’s are like this but both of the ones I tested performed the same. They have the same capacity as the 25R5 but run at a lower voltage, i.e., they don’t hit quite as hard. Tyhe 25R6M does run a bit cooler than the 25R5 though.

I am rating the 25R6M at 20A and 2500mAh.

My thanks to IMRBatteries for donating the two cells for testing (www.imrbatteries.com)!
