ENGINEERING HIGHLIGHTS
- Precision Automated Grading: Every pouch cell is matched within <5mV voltage delta and <0.2mΩ resistance tolerance prior to ultrasonic busbar welding.
- Impact & Puncture Resistance: Flame-retardant ABS hardcase guards against gravel intrusion, chassis bottoming out, and high-G crash impacts.
- Consistent High Current Delivery: Heavy-gauge silicone leads and gold-plated terminals minimize contact resistance and prevent thermal softening during full-throttle bursts.
