The LiFe² pairs Active Battery Management with LiFePO4 Prismatic Cells, built for tough Australian conditions. Expand it with Plug‑and‑Play Cabinets, and keep running with Automatic Fallback to Self‑Management if comms are lost (when used with supported inverters).

Easy to connect

Managed or Self‑Managed operating modes.

Scalable

Up to 64 battery modules in parallel.

Hot swappable

Easily swapped without system interruption.

Reliability

Automatic fallback to Self‑Managed if comms are lost. (when used with supported inverters)

LiFePO4

LiFePO4 chemistry housed in a robust prismatic cell construction.

Easy installation

Quick plug‑and‑play connections save time on site.

Pre‑wired cabinets

Choose from 4, 6 or 10 battery module pre‑wired cabinets.

Remote monitoring

Performance and system management through AERL Cloud.

Warranty

5 years, or a 10‑year 70% product and performance warranty when registered within 60 days of installation. (Conditions apply)
