🛡️ 3. Safety Features & Protections

⚠️

Smart Thermal Protection

Linear derating above 85°C MOSFET temperature; full shutdown cut-off over 100°C.

⚠️

Hardware Overcurrent & Short-circuit

Closed-loop response under high current (<10ms), microsecond-level gate shutdown protection.

⚠️

Over/Under-Voltage Lockout

Prevents over-discharge/charge of battery packs; includes regenerative braking overvoltage lockout.

⚠️

Failsafe Loss-of-Signal

Safe deceleration and braking within 100ms upon loss of RC or CAN bus control signals.
