LiFePo4 12V 100Ah Lithium Iron Phosphate Deep Cycle Battery. CALB Cells

  
I also have extensive experience qualifying and testing lithium batteries. This listing is for a 4 pack of CALB cells. Copper buss bars and bolts included. The spec below is the result of 4 cells connected in series. Nominal Voltage = 12.8V. Cycle Life > 5000 times. Max Charge Current = 50A.

Max Charge Voltage = 14.6V (3.65V per cell). Max Continuous Discharge Current = 100A.

End of discharge voltage = 10V. Weight of 4 cells is 29lbs.
