🔋 90-day warranty is the industry standard for replacement batteries. Batteries naturally lose capacity over time — this normal wear is not covered. Warranty applies to manufacturing defects only.

Frequently Asked Questions

This 14500-2S 6.4V 500mAh LiFePO4 battery with SM-4P connector is designed for WLtoys 6WD RC crawlers (1:18 scale 6WD off-road climbing vehicles). The battery pack is pre-assembled with two 14500 cells in series. Please verify your vehicle uses SM-4P connector and battery compartment size approx. 53×28×14mm before purchasing. This is a 2S Li-ion battery — not compatible with 1S or 3S systems.

This is a 2S (2-cell series) LiFePO4 battery pack. Each 14500 cell has a nominal voltage of 3.2V, so the pack delivers 6.4V nominal. Full charge voltage is approximately 7.2V-7.4V (3.6V-3.7V per cell). Discharge cut-off is 5.0V-5.6V (2.5V-2.8V per cell). Always use a compatible 2S Li-ion balance charger (6.4V-7.4V range). Never use a 1S charger or higher voltage charger.

Actual runtime depends on your vehicle's power draw — motor size, weight, terrain, and throttle usage. For a typical WLtoys 6WD 1:18 scale crawler, you can expect approximately 15-25 minutes of runtime on a full charge on mixed terrain, or 30-40 minutes on flat surfaces with light throttle. For extended climbing sessions, we recommend carrying a spare battery. Always allow the battery to cool down before recharging.
