The Fox ESS CQ16 Battery Base is the floor-mounting base plate required beneath every
stack of Fox ESS CQ16 high-voltage battery modules. It provides a stable, level foundation for stacking
up to four CQ16 modules, keeping the battery bank securely supported and correctly aligned for safe cable and
communication connections.

One Base Required per Stack
Each stack of up to 4 CQ16 battery modules requires its own Battery Base. For multi-stack systems, order one Battery Base for every stack in the installation.
Part of the Complete CQ16 System
The Battery Base is one of the required accessories ā alongside the BMS Control Box and a Cable Pack per stack ā needed to build a complete, working Fox ESS CQ16 battery installation.
Stable Stack Foundation
Provides a level, purpose-fitted base for stacking CQ16 battery modules, keeping the weight of a fully loaded stack evenly distributed and securely positioned.
Matched to CQ16 Module Footprint
Designed to the same 390 Ć 235mm footprint as the CQ16 battery modules, ensuring a precise, purpose-built fit rather than a generic mounting solution.
Simplifies Multi-Stack Installations
For systems built from several parallel stacks, using one Battery Base per stack keeps each column of modules independently supported and correctly spaced for servicing access.
