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.

✅ Why Our Warranty Stands Out

Unlike marketplace sellers with short buyer protection windows, we handle claims directly — no automated disputes, no endless back-and-forth.

Compare ✅ Qingsm Tech ⚠️ eBay / AliExpress
Warranty Period 90 days from delivery 15-30 days from order confirmation
When It Starts 📦 Upon delivery ⚠️ Upon order confirmation (even before you receive it)
Claims Handling We do it directly — email us Automated dispute system, seller dependent
After Window Expires Still can contact us for support No recourse, seller can ignore you

🔋 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

LiFePO₄ (Lithium Iron Phosphate) is a safer, longer-lasting lithium battery chemistry. Key differences:
- Voltage: 3.2V per cell (vs 3.7V for Li-ion)
- Full charge: 3.65V per cell (7.3V for 2S)
- Cycle life: 2000+ cycles (vs 500 cycles for Li-ion)
- Safety: Much lower risk of thermal runaway

This 2S LiFePO₄ battery is rated 6.4V (nominal) — NOT 7.4V. Using a 7.4V Li-ion battery in a device designed for 6.4V LiFePO₄ can damage your electronics. Always check your original battery voltage before ordering. For reference, similar 2S LiFePO₄ batteries on AliExpress sell for $8-14, Amazon for $12-20.

Use ONLY a charger designed for 2S LiFePO₄ batteries (6.4V nominal). DO NOT use a standard Li-Po charger set to 7.4V. Steps:
1. Set charger to LiFePO₄ mode with 2S selected
2. Full charge voltage: 7.3V (3.65V per cell)
3. Recommended charge current: 0.75A (1C)
4. Connect BOTH plugs: JST-2P (discharge) and SM-3P (balance)
5. Never leave the battery unattended while charging
6. Do not discharge below 5.0V (2.5V per cell)

The SM-3P balance plug ensures both cells charge evenly. Never charge without connecting the balance plug, as this may cause cell imbalance.

For maximum lifespan (up to 2000+ cycles):
1. Use ONLY a LiFePO₄ charger — never use a standard Li-Po charger
2. Always balance charge using both JST-2P and SM-3P plugs
3. Do not discharge below 5.0V (2.5V per cell)
4. Store at 40-60% charge at room temperature
5. Allow the battery to cool before recharging
6. Never leave the battery unattended while charging
7. Avoid physical damage to the battery pack
8. If the battery swells or becomes hot, stop use immediately

LiFePO₄ is more forgiving than Li-Po but still requires proper care. Balance charging every cycle is the key to long battery life.
