FAQ:
Q: What are the advantages of LiFePO4 over standard Li-ion batteries?
A: LiFePO4 (Lithium Iron Phosphate) batteries offer significantly better safety (they are non-combustible), excellent thermal stability in hot conditions, and a much longer cycle life. This makes them a superior choice for high-drain RC vehicles that run hard.
Q: What does "15C" mean?
A: 15C is the discharge rate. For an 800mAh battery, 15C equals a maximum continuous discharge of 12A (800mA x 15). This means the battery can instantly deliver a massive burst of power to your RC car for higher top speeds and stronger climbing ability.
Q: Is this battery plug-and-play with my WLtoys car?
A: Yes, provided your WLtoys model operates on a 6.4V system and uses the same SM-4P connector type. Please check your original battery's plug shape and voltage before ordering.
Q: What happens if I connect the polarity incorrectly?
A: If you connect the battery with reversed polarity, it will instantly short-circuit and burn out your RC car's ESC (Electronic Speed Controller). This is permanent damage and is not covered by warranty. Always ensure the red and black wires match your vehicle's original wiring before connecting.
Q: How long does it take to charge this battery?
A: Charging time depends on your charger. We recommend using a dedicated 6.4V / 7.4V Li-ion RC battery balance charger. With a 1A charging current, it will take approximately 50 to 60 minutes.
