Specifying a Security System pack without the usual template paragraph

Security system backup power. The useful question is hours and ambient, not a synonym for lithium. ChargeX builds LiFePO4 packs (CAGE 93CZ2, UN38.3) and will quote the voltage your equipment already uses.

CAGE 93CZ2

UN38.3 transport docs on request. DUNS 109774429. We do not publish a star rating we cannot source.

This rail: Trolling motors, mid-size solar, light commercial

Typical size: Typical 100–400Ah

What actually fails

  • Cameras and gates fail at 2 a.m. when the wet cell is at 11.8V and it is 20 F.

How we quote it

  • Size for the longest winter night plus the strobe or motor inrush, not average draw.

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 Security System constraints above should still make sense. That is the point.

Security System: the constraints that survive a find-and-replace test

Security system 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.

Spec note

Questions we actually get

How do I size a Security System 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.
