Power up your RC high speed toy car with this 16500 6.4V 750mAh 2S LiFePO₄ battery. Unlike standard 7.4V Li-ion packs, this LiFePO₄ (Lithium Iron Phosphate) battery offers superior safety, longer cycle life (2000+ cycles), and stable voltage output under load. The 15C discharge rate provides reliable power for high-speed runs and responsive handling. Features a dual‑plug design: JST-2P for discharge and SM-3P for balance charging. The compact 52×32×16mm size fits most RC toy battery compartments. Built with grade A cells and multi-layer safety protection against overcharge, over-discharge, and short circuits. CE and RoHS certified.
LiFePO₄ Advantage: LiFePO₄ batteries are safer than traditional Li-ion/Li-Po, resist thermal runaway, and last up to 4x longer (2000+ cycles vs 500 cycles). They maintain stable voltage during discharge, providing consistent power to your RC car’s motor. The lower voltage (6.4V) is specifically designed for devices that require this specification — check your device’s original battery voltage before ordering.
Dual Plug Design Note: This battery includes both a discharge plug (JST-2P) and a balance charge plug (SM-3P). The JST-2P connector powers your RC car. The SM-3P connector is for balance charging with a compatible 2S LiFePO₄ charger — this ensures both cells charge evenly for maximum lifespan.
Charging Instructions: Use ONLY a charger designed for 2S LiFePO₄ batteries (6.4V nominal). Do NOT use a standard Li-Po charger set to 7.4V — this will overcharge and damage the battery. Set charger to LiFePO₄ mode with 2S selected — full charge voltage is 7.3V (3.65V per cell). Recommended charge current: 0.75A (1C). Connect both the JST-2P and SM-3P plugs during charging. Never leave the battery unattended while charging. Do not discharge below 5.0V (2.5V per cell).
Battery Care Tips: Avoid over-discharge — stop running your RC car when you notice reduced speed. LiFePO₄ batteries tolerate more abuse than Li-Po but still benefit from proper care. Allow the battery to cool before recharging. Store at 40-60% charge at room temperature. If the battery swells or becomes hot, stop use immediately.
