01 / Modular energy storage
Select a cell
Use a cell while it is inside its operating limits.
Each position needs voltage and temperature sensing, a defined series path and independent protection. Mixed capacities do not remove current limits.
Modular energy storage
A battery with more than one way through.
Explore a serviceable LFP pack where individual cells can join or leave the series chain, with a protected output for habitats and remote instruments.

How it works
Follow the system.
One part at a time.
Select a part to see its role, the decisions behind it, and what still needs evidence.
02 / Modular energy storage
Pause the current
Stop the load or charger before changing paths.
The proposed sequence confirms current has fallen before operating a selector. This architecture does not establish seamless hot swapping.
03 / Modular energy storage
Route around
Bypass a cell that has reached a limit.
Removing cells reduces string voltage. Every remaining series path and bypass path must still carry load current; the converter input range limits how far bypass can go.
04 / Modular energy storage
Protect the output
Give the habitat a predictable power interface.
Conversion, current limiting, isolation and thermal protection belong inside the module. Logging may need a separate supply to survive switching interruptions.
Design principles
What guides the work.
Service a position
Study replaceable cell positions and accessible electrical assemblies.
Account for the whole pack
Compare switches, conversion, protection and enclosure with conventional protected LFP storage.
Keep a reference
A conventional fixed-series pack remains the comparison for usable delivered energy and total cost.
Project status
Know where
the work stands.
Research architecture. Cell switching, protection and the complete pack remain unbuilt and unrated. Switching is proposed at zero current and interrupts output.
