Frequently Asked Questions

Q: Can I use this battery if my ESC has a different connector?
A: Yes, but you need an EC5‑to‑your‑plug adapter or solder an EC5 onto your ESC. We recommend soldering for best performance.

Q: Why is the hard case necessary?
A: It protects cells from impact and puncture during crashes, and ensures a snug fit in the battery tray to prevent shifting.

Q: How long will it run on a full charge?
A: Typically 20‑35 minutes of aggressive driving, depending on motor, gearing, and terrain. Use a low‑voltage alarm for accurate monitoring.

Q: Is 7.5A charging safe?
A: Yes, 1C (7.5A) is safe. For longer cycle life, charge at 0.5C (3.75A) when time allows.
