Please Notice

Use a 12S‑compatible LiPo charger and set cut‑off at 3.0V/cell (low) / 4.2V/cell (high).

Never discharge below 3.2V/cell under load – reduces cycle life.

Charge in a fire‑proof bag on non‑flammable surface; never leave unattended.

Inspect leads/plug before each use; replace if damaged.

Storage voltage: 3.8~3.85V/cell (45.6~46.2V total) for >7 days.

FAQ

Q1: Is this battery directly compatible with my ESC that uses AS150U?
A1: Yes. If your ESC uses a different connector, you’ll need an adapter rated for at least 150A continuous.

Q2: How does semi‑solid electrolyte improve safety?
A2: It reduces internal short‑circuit risk and suppresses thermal runaway. Even if punctured, it leaks less flammable solvent and burns less violently, giving you more reaction time.
