Azalea Aviation is proud to partner with Aerolithium to offer 2nd-generation sodium-ion batteries as a direct replacement for lead-acid batteries in experimental aircraft. After months of research and battery design, Aerolithium has developed a platform that combines exceptional safety, a wide operating temperature range, and long service life — with no fault-monitoring BMS required.

Safety

Sodium has zero propensity for exothermic reaction — no flame, no smoke, no internal cell swelling, and no overheating. It is safer than both LiFePO4 and lead acid, and requires no fault light or BMS fault monitoring. There are no weak-point failure modes like those found in lithium chemistries, which means no unexpected shutdowns and no "battery fault" indicator needed in the cockpit.

Operating Temperature Range

Sodium-ion operates across a far wider temperature range than lithium or lead, and is less sensitive to thermal extremes — making it well suited to aircraft operating in varied climates and altitudes.

Voltage Behavior

For 12V systems the operating range is 6 to 16 volts. The battery can be fully discharged to zero volts with no cell damage — eliminating the risk of a sudden BMS cutoff that could cause loss of all aircraft power. No "smart battery" fault monitoring system is required.

The discharge curve is linear, making state-of-health and state-of-charge straightforward to read from a simple voltage display — no complex monitoring needed.

Because sodium acts as a voltage stabilizer, it accepts wide voltage variations and buffers alternator output exactly like lead acid — but without the weight penalty or the risk of an unexpected BMS-triggered power loss.

Performance Comparison

Here is how sodium-ion stacks up against the leading alternatives:

Pricing & Availability

Pricing is coming soon. Sodium cells cost less to manufacture than comparable lithium batteries — expect approximately 75% of the cost of a comparable LiFePO4 battery. Batteries are available in custom Ah sizes to suit your aircraft's requirements.
