Aeson Power says game changing battery tech gives 4×4 owners another option

Whether it is a Ford Ranger towing a dual-axle van or a Toyota LandCruiser 79 Series heading to the Cape, payload disappears fast once you add a bull bar, canopy, and a fridge full of supplies. Add towing, and owners can quickly breach legal limits.
To stay insured and compliant, a Gross Vehicle Mass (GVM) upgrade is often required.
Under Australian Design Rules and state engineering regulations, upgrades can legally increase GVM by 300-600kg on popular dual cabs. Fully engineered, that typically costs $4,000–$6,500, says Aeson Power.
Typical OEM lead-acid batteries weigh 23-30kg, says Aeson Power, which states that its StratoForse sodium-ion start battery range is 40-60 percent lighter, saving 10-16kg instantly, depending on size.
Crucially, that weight comes off the front axle, which is critical for steering, suspension, and tyre wear.
In practical terms, 15kg equals 15 litres of water, a full recovery kit, or valuable tow ball download margin.
Weight saving is only part of the story though, says Aeson Power, which states its StratoForse delivers equal or higher CCA than comparable lead batteries, with low internal resistance giving faster charge recovery after cranking – making it ideal for accessory-heavy modern vehicles.
Unlike lead or lithium, Aeson Power states sodium-ion chemistry thrives in engine-bay heat, operating from -30°C to +80°C.
Further, it states repeated partial state-of-charge cycling – common in touring vehicles running fridges, lighting and compressors – doesn’t damage the chemistry.
According to Aeson Power, the “incredible” discharge rate of 25C for the StratoForse delivers high performance winching. And paired with a charge rate of 5C, it means the battery is no longer the limiting factor.
In theory, a 100Ah unit could accept 500A and recharge in under 15 minutes, says Aeson Power.
StratoForse is rated for up to 120,000 engine starts and can safely discharge to 80 percent DoD when required.
At 50 percent DoD, the company says it can deliver up to 3,000 cycles, which it states is “far beyond the dreams of a conventional lead start battery.”
Aeson Power says with no thermal runaway, StratoForse is non-toxic, sealed, and acid-free, with no sulphation while being maintenance-free, and able to recover from zero volts without permanent damage to performance or life.
StratoForse models are backed by a three-year warranty, or five-year warranty for the top-of-the-line StratoForse-SS+.
Aeson Power says pricing is comparable to premium AGM and up to 50 percent less than equivalent under-bonnet lithium.
