About this file
This Statement of Need outlines NOAA PMEL's Engineering Development Division's requirement for 60 custom lithium battery packs for GPS mooring buoys supporting NASA's SWOT satellite calibration project.
The battery packs must meet specific technical requirements including: maximum dimensions of 5.85" diameter and 5" height, compatibility with PMEL GPS buoys, configuration of 14 cells (12 active + 2 dummy cells), use of Electrochem BCX 85 DD: 3B0076 cells with 30Ah/cell capacity, 4S-3P pack arrangement, and 2-foot external 22 AWG cable with Teflon insulation. The delivery schedule requires completion within 90 days after receipt of order (ARO), with shipping to be handled via Government Bill of Lading (GBL). The document includes detailed technical diagrams showing the battery pack configuration and system integration details.

● Max Height: 5"
● Must fit on PMEL GPS buoys and be compatible with the GPS buoy system (see drawing)
● 14 cells (12 cells + 2 dummy cells)
● Cells are BCX 85 DD: 3B0076 made by Electrochem
● 30Ah/cell
● External 22 AWG cable - 2 ft
● Wires are 22AWG 600V Teflon insulated
● Qty 60: 4S-3P packs
DELIVERY SCHEDULE:
Delivery by 90 days ARO or sooner
Shipping will be using Government Bill of Lading (GBL). Shipping information will be provided by the government.
