Is this battery compatible with the FJ400?
No, the Westcott FJ ProMax Battery for FJ800 and FJ400 II Strobes is not compatible for use with the original Westcott FJ400 400Ws Strobe with AC/DC Battery (US/No. America Plug). The new Westcott FJ ProMax Battery for FJ800 and FJ400 II Strobes is currently only compatible for use with the Westcott FJ800 800Ws Touchscreen Strobe and the Westcott FJ400 II 400Ws Touchscreen Strobe. If you need a replacement battery for the original Westcott FJ400 400Ws Strobe, then the Westcott Lithium-Ion Polymer Battery for FJ400 AC/DC Strobe, B&H # WEFJ400ACDC, would be the correct option compatible for your usage needs. https://bhpho.to/3Yi9nP4
