Frequently Asked Questions

What is the main benefit of 800V over 400V for eVTOL?
+

At the same power, 800V uses half the current of 400V. This reduces resistive heat loss (I²R) by 75%, allows lighter cabling, and enables faster charging (5C vs 2–3C). For long‑range missions (>150 km), 800V is significantly more efficient.
Can I charge this battery with existing ground chargers?
+

Most high‑power EV chargers support 800V (e.g., CCS2, GB/T, CHAdeMO 3.0). We also provide custom aviation‑grade chargers that communicate with our BMS via CAN bus. Please specify your charging infrastructure when ordering.
Is immersion cooling necessary? Is it safe?
+

Liquid cooling is optional but highly recommended for sustained high‑C rate operation (climb + cruise above 4C). It also acts as a thermal runaway suppressant – a critical safety feature for manned eVTOL.
How does this high‑voltage battery compare to your mid‑voltage series?
+

Mid‑voltage (200‑600V) is ideal for full‑scale eVTOL with flight times under 60 minutes and ranges under 150 km. High‑voltage (600‑800V) is designed for regional air mobility (200‑400 km range), carries more energy (50‑120 kWh vs 15‑35 kWh), and supports 5C fast charging. Choose high‑voltage if you need extended endurance and rapid turnaround.
Can you customize the voltage to exactly 700V or 750V?
+

Yes. By adjusting the number of cells in series, we can match any voltage between 600V and 800V. Please provide your motor controller's nominal and maximum voltage specifications.
