Product overview
Ultra high energy density designed for endurance-focused applications, reaching up to 450 Wh/kg.
The Skyward 400 is built on AFLMB chemistry in a 11 × 87 × 187 mm format, rated at 50 Ah and 3.81 V with an energy density of 400±10 Wh/kg. Full specifications are listed in the table below.
This series puts energy density first. The 380 keeps an NCM-Si/Gr chemistry, while the 400 and 450 switch to anode-free lithium metal (AFLMB) to reach 400–450Wh/kg. The trade-off is lower discharge rate and cycle life, which suits missions where single-flight endurance matters far more than sortie count.
Evaluate lifetime cost against total planned sorties: the 450 is rated for 50 cycles at 25℃ (0.2C/0.5C) and is not a drop-in replacement for standard production airframes.
