24V on this URL
Halves current versus 12V for the same watts. Confirm the motor or inverter is actually 24V before you order.
If you delete the voltage, the Access Control constraints above should still make sense. That is the point.
What to spec for Access Control
Access control backup power Remote sites need a BMS alarm, not a truck roll every quarter to water cells. Voltage overlay on this URL is only there because the equipment rail is real — delete the voltage and the duty-cycle advice should still read as a sentence. Halves current versus 12V for the same watts. Confirm the motor or inverter is actually 24V before you order.

Questions we actually get
How do I size a Access Control lithium bank?
Watts × hours, then divide by voltage and by 0.8 if you want 80% depth of discharge. Add the worst ambient. That beats any calculator widget.
Can I keep my existing charger?
If it can hold a lithium charge curve (higher absorb, little or no float), maybe. Send the charger model. A lead-acid-only charger is how people cook packs.
What paperwork can you send?
UN38.3 is the usual transport packet. CAGE 93CZ2 and DUNS 109774429 for government bids. Other marks depend on the SKU — we send PDFs we actually have.
