These PXI battery simulators are designed to simulate the power supplies of portable battery powered equipment and the single cell (model 41-753) is particularly suitable for cell phone testing. These modules can source current to simulate a battery supply or sink current to simulate a battery under charge. 

The 6-cell battery simulator (model 41-752) is ideal for emulating the battery stacks used for electric vehicles. It's high density and high isolation voltage barrier permits it to be used with many cells in series, making it possible to emulate a battery stack of up to 108 cells in a single PXI or LXI chassis.
