These ones were pulled from new server racks, they were 120V, 6 per unit (3s2p). But brand new never used. Very heavy, if wanted a whole one.
A123 26650 LFP 40v 96 cell (Rack Style) W/ BMS. Pack Dimensions are 30" x 6.5" x 2.75. They are testing at 90-95% and above, 43.4V was the first 2. I'll guarantee 90% and above now.
43.8V is the max capacity. Price is for ONE pack ONLY.A123 40v battery pack ANR 26650 Rechargeable battery Lithium Ion Po LiFePO4. Max Voltage = 43.8v 876wh. Run as 36v battery pack or Cut into 3 12v pack, not that easy but its doable.
BMS works perfect, series to 72v or 108v or more; could be parallel as well. Very good pack, 95-99% capacity.
