Product Description

Product Overview

The Mid-Voltage (200-600V) eVTOL Battery Series is engineered for full-scale testbeds and commercial eVTOL propulsion systems, supporting both vertical takeoff power bursts and high-efficiency cruise discharge.It delivers the power and thermal stability required for climb, cruise, and certification flight tests.

Key Advantages

High power output for lift and hover phases
Stable discharge for cruise performance
Aviation-grade high-speed BMS with fault-tolerant control
Modular engineering for easy scaling and maintenance
High environmental adaptability for high-altitude flight loads

Why Choose Mid‑Voltage (200–600V) Over Low or High Voltage?

Balanced efficiency – lower current than 200V systems (reducing wiring weight), but without the high‑voltage isolation complexity of 800V.
Compatible with common motor controllers – most eVTOL prototypes and production aircraft use 400V–600V bus architecture.
Safer for ground handling – compared to 800V, mid‑voltage reduces arc‑flash risk while still offering high power density.

Engineering Strength- Built for Airworthiness

Supports repetitive high-current lift demand
Efficient cooling for long-duration flight tests
High-precision state estimation for propulsion safety
The pack has been successfully flight‑tested in multiple eVTOL programs

Frequently Asked Questions

What is the difference between mid‑voltage (200‑600V) and low‑voltage (0‑200V) for eVTOL?
+

A: Low‑voltage (0‑200V) is mainly used for prototypes, subsystem verification, and auxiliary power. Mid‑voltage (200‑600V) is designed for full‑scale eVTOL propulsion – it delivers much higher continuous power and supports liquid cooling, which is necessary for climb and cruise in a manned aircraft.
Can I use ordinary EV batteries in my eVTOL?
+

Not recommended. Ordinary EV batteries (e.g., from cars) are designed for lower continuous C‑rates and lack aviation‑grade vibration resistance, thermal runaway containment, and redundant BMS. Our mid‑voltage battery is Qualified by Professional Industry tested and uses aerospace‑grade materials to prevent cell‑to‑cell propagation.
Is liquid cooling mandatory for mid‑voltage eVTOL batteries?
+

For short flights (under 15 minutes) with low average C‑rate, passive cooling may suffice. However, for typical eVTOL missions (climb + cruise + descent) requiring sustained 3‑4C discharge, liquid cooling is strongly recommended to maintain cycle life and safety.
Can you customize the voltage exactly to my motor controller (e.g., 450V)?
+

Yes. We can adjust the series cell count to match any voltage between 200V and 600V. Please provide your controller’s nominal and max voltage specifications.
