B02Battery packs

Store energy for eclipses and peak demand.

Manufacturers & products

Satellite batteries can be purchased as qualified cells, screened cell lots, protected packs, or complete thermal/electrical battery systems. Cell performance cannot be carried unchanged into a flight pack; protection electronics, balancing, containment and heaters alter the usable energy and mass.

These are sourcing candidates, not a confirmed Starlink supply chain.

What remains unverified

Public battery life claims often omit at least one operating condition. They have not been converted into guaranteed mission years.
The actual V2 Mini cell, pack and battery-management suppliers were not established.
Several vendors expose batteries primarily within a complete EPS; standalone procurement is noted as unconfirmed where applicable.

Where it comes from

A company address is shown separately from a published factory location. Request the manufacturing site and lot traceability for the exact part when sourcing.

What to compare

Usable eclipse energy · Wh
Size using permitted depth of discharge, EOL capacity, temperature and converter losses rather than nameplate Wh.
Chemistry and cell provenance
Record chemistry, cell manufacturer/lot screening and whether the supplier builds cells or assembles purchased cells.
Voltage window · V
Match series count, charge termination and depleted voltage to the EPS and loads.
Charge and discharge limits · A, s
Separate sustained and pulse current and include the duration and temperature of each rating.
Cycle and calendar life
Compare cycles only at the same depth of discharge, temperature, rates and retained-capacity endpoint.
Thermal control · °C, W
Check permitted charge temperature, heater power, thermal interfaces and sensor redundancy.
Fault protection and balancing
Review cell isolation, over/undervoltage protection, short-circuit response and balancing strategy.
Mass, envelope and acceptance · kg, mm
Distinguish cell-only from complete-pack mass and identify testing/containment included in the deliverable.

Selection & integration notes

A battery pack supplier may source cells from a different company; these are two supply-chain nodes and should remain distinct in the website.
Rechargeable eclipse storage is the relevant baseline. Primary and thermal batteries belong to different spacecraft functions and are not substitutes.
Use the EPS charge algorithm and thermal plan as part of battery selection, not after procurement.
