Zenaji

Zenaji's defining choice is chemistry. Where most home batteries use lithium iron phosphate (LFP) or NMC cells, the Zenaji Aeon uses lithium titanate oxide (LTO) — a chemistry valued for cycle life, safety and tolerance of extreme temperatures. Each Aeon module holds 1.93 kWh, can be discharged to 100%, and is rated for operation from -40°C to 60°C; systems scale by adding modules, so storage can be sized in small steps rather than fixed blocks.

LTO's trade-off is well understood — it is less energy-dense and costs more per kWh than LFP, so a Zenaji system carries a higher upfront price for a given capacity. In return, Zenaji backs the Aeon with a 20-year or 22,000-cycle warranty (whichever comes first) to at least 80% retained capacity, around double the 10-year cover most rivals offer.

For Perth homeowners, the Aeon suits those who value longevity and daily deep cycling over the lowest upfront cost — for example, heavy users who cycle storage more than once a day. Confirm current pricing, module count and installer familiarity before purchasing.
