Product Description:
Upgrade your off-road performance with the 6.4V 800mAh 15C LiFePO4 RC Battery Pack with SM-4P Connector. Designed specifically for high-drain RC applications, this premium battery pack combines two 16500 cells in a 2S series configuration, utilizing advanced LiFePO4 (Lithium Iron Phosphate) chemistry to deliver a stable 6.4V output, massive 15C discharge rate, and exceptional safety.
Whether you are tearing through rugged terrain or racing at top speeds, this battery provides the instantaneous burst power your WLtoys 6-wheel off-road RC truck needs. It comes with a factory-installed SM-4P connector and pre-soldered wires, making it a perfect, ready-to-use drop-in replacement.
CRITICAL SIZE & POLARITY WARNINGS:
-
Size Alert: The physical dimensions of this battery pack are 54mm (Length) x 33mm (Width) x 18mm (Thickness). Please measure your RC car's battery compartment carefully before purchasing to ensure a proper fit.
-
Connector Polarity Warning: This battery pack is equipped with a specific SM-4P connector and polarity layout designed for WLtoys 6-wheel series. Please verify the plug shape and the polarity (+ and -) of your original battery before ordering. Connecting a battery with incorrect polarity will instantly burn out the ESC (Electronic Speed Controller) of your RC car, which is irreversible damage.

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.
