A client from the Bahamas ordered 64 pieces of CALB L173F230 3.2V 230Ah Lithium iron phosphate lifepo4 battery prismatic cells for the solar system, and he has used CALB CA180 lifepo4 prismatic battery cells for many years, and it was time to change the new battery cells. He is a loyal customer of CALB batteries, so we recommended the new CALB L173F230 230Ah lifepo4 battery cell, which has an aluminum case, and a bigger capacity because the model of CA180 lifepo4 battery cells had suspended production. We provided him the studed version, and free busbars, bolts for the easy connection, and he will build four 16S 48V lifepo4 battery banks for his solar systems use these 64 230Ah lifepo4 battery cells.
Before the shipment, we tested every single 230ah lifepo4 battery cell with the item of appearance, open circuit voltage, internal resistance and capacity, package and mark, and issued a test report, it show the voltage is around 3.245~3.285v, the internal resistance is around 0.1~0.5m¦¸, and the capacity is around 242.5~250.5ah, is 8% higher than the nominal capacity; the battery cells we provided were all brand new grade A LiFePO4 cells.
