Quick FAQ

Q1: Can I use this battery on my drone/car/plane?
A1: Please check your device's voltage, connector type, and size. Match them with our product specifications.
Q2: What charger should I use?
A2: We recommend a smart balance charger that supports LiPo/Li-ion charging modes such as B6, ISDT, or ToolkitRC.
Q3: How long does it take to fully charge?
A3: Charging time depends on battery capacity and charger output. As a rule of thumb: Charging Time ≈ Capacity (Ah) ÷ Charging Current (A).
Q4: Do the batteries come pre-charged?
A4: Batteries are shipped at 30–50% storage voltage for safety. Please fully charge before use.
Q5: Is it normal for batteries to get warm?
A5: Slight warmth is normal during use or charging, but overheating may indicate a problem. Always monitor during use.

✅ Final Tips Before You Fly

  • Always charge in a fireproof bag and never leave unattended.
  • Do not over-discharge (below 3.0V/cell) or overcharge (above 4.2V/cell).
  • Balance charge regularly to prolong battery life.
  • Inspect battery and connectors before each use.
  • Store at room temperature (recommended 3.7–3.9V/cell if unused for long periods).
  • Match your battery’s C-rating and capacity to your RC model’s power demands.
