Can Sentinel Mini be reviewed for LiFePO4 batteries?
Yes. AEL can review LiFePO4 and other lithium-ion battery formats. Final suitability depends on battery dimensions, quantity, condition, spacing, intended activity, and installation requirements.
What is included with the standard cabinet?
The standard starting configuration includes the selected cabinet, three perforated-steel shelves (three levels of wraparound shelving on the Mini 100), locking doors with perimeter seals, side louvers, and a fabricated handling base.
Is active ventilation included?
No universal active-ventilation package is included. Optional exhaust, CP2000 advanced ventilation, monitoring, alarms, and controls are selected by application.
Does AEL publish one universal energy limit?
No. AEL does not assign one universal energy limit to every cabinet. Battery energy, geometry, quantity, condition, intended activity, and project requirements must be considered together.
Can I ask questions before buying?
Yes. Use Request Information for product guidance or engineered options beyond the standard configuration.
