About this file
This document outlines the requirements for a competitive procurement of Conformal Wearable Batteries. The Government estimates procuring 945,987 batteries over a potential nine-year contract consisting of a three-year base period and six one-year options. Offerors must submit four hardware samples along with a written technical proposal for evaluation, with one unsealed sample containing actual internal components and three samples to be tested against requirements. The testing will evaluate dimensions, weight, communication protocol, discharge and charge performance at various temperatures and voltages, flexibility, and other criteria as defined in the attached test plan. The opportunity provides advance notice of forthcoming requirements but is not itself a solicitation, as no proposals or responses will be reimbursed at this time.

PROPOSED AMENDMENT:
1. The Government is projecting the procurement of 945,987 Conformable Wearable
Batteries (CWB) over the course of a three year base period and six, one-year options for a potential contract duration of nine years. These are estimates and are subject to change.
The official solicitation that will be posted will trump any conflicting information.
2. The Government will employ a source selection process that will require total of four (4) hardware samples in conjunction with a written technical proposal. One (1) hardware sample must be unsealed, but contains the actual layout of all the internal components.
Inert (dummy cells) must be used for this sample. Three (3) Hardware samples will be tested to validate the design and performance characteristics as described in the written proposal. The testing will evaluate the following Criteria, and the protocol will be defined in the Bid Sample Test Plan attached to the solicitation.
