For sale. 11.1v Lithium battery pack. It appears to be 9 (18650?) cells it total. So 3 cells in parallel, 3 times, to get the voltage? This is from a Subzero MP8 battery PA rated at "100w" I don't think these have had much use. The PA units seem to be DOA or customer returns. It is 2 wire, and charged to 12v.Two available
