Internal resistance difference of lithium iron phosphate batteries in parallel

First of all, we should know that when two or more lithium iron phosphate batteries are connected in parallel, the current flowing through each battery cannot be exactly equal. For example, suppose you are using two 12V 100Ah batteries in parallel. When the battery system is connected to a 50A load, the load on each cell. . Current imbalance between cells is caused by field installation variables. For example, differences in cell and battery manufacturing processes, differences in cell connection resistance, and temperature differences. . Before connecting batteries in parallel, you may need to pay attention to the following matters. 1. Do not mix different brands and capacities of batteries Make sure the parallel-connected batteries match strictly internal resistance:. . When connecting two or more batteries in parallel that are new and have the same capacity and voltage brand, the power pushed between the. [pdf]
