Power up your RC electric toy with this 18350 2000mAh 11.1V 3S Li-ion battery. This battery uses three high-quality 18350 cells (18mm × 35mm each) connected in series to deliver 11.1V power for high-performance RC devices. The slim 110×18mm cylindrical shape fits many compact battery compartments. Features a dual‑plug design: SM-2P for discharge and XH-4P for balance charging. Built with grade A cells and multi-layer safety protection against overcharge, over-discharge, and short circuits. CE and RoHS certified.

18350 Cell Advantage: 18350 cells are shorter than 18650 (35mm vs 65mm), making them ideal for compact 3S configurations. This 3S1P pack delivers 11.1V nominal (12.6V max) for RC devices requiring higher voltage for speed and power.

Dual Plug Design Note: This battery includes both a discharge plug (SM-2P) and a balance charge plug (XH-4P). The SM-2P connector powers your RC device. The XH-4P connector is for balance charging with a compatible 3S Li-ion/Li-Po charger — this ensures all three cells charge evenly for maximum lifespan.

Charging Instructions: Use only a balance charger designed for 3S (11.1V) Li-ion/Li-Po batteries. Set charger to Li-Po mode with 3S selected — full charge voltage is 12.6V. Recommended charge current: 2.0A (1C). Connect both the SM-2P and XH-4P plugs during charging. Never leave the battery unattended while charging. Do not discharge below 9.0V (3.0V per cell).

Battery Care Tips: Avoid over-discharge — stop using your RC toy when you notice reduced power. Always balance charge for maximum battery life. 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 and recycle properly.

Frequently Asked Questions

18350 and 18650 are both Li-ion cylindrical cells. The key difference is length:
- 18350: 18mm diameter × 35mm length (shorter)
- 18650: 18mm diameter × 65mm length (longer)

This battery uses three 18350 cells in series (3S), creating a compact 110×18mm pack perfect for devices with limited space. 18350 cells are ideal for compact RC toys where shorter battery length is required. For reference, similar 3S 18350 batteries on AliExpress sell for $10-16, and Amazon for $15-22. This battery is NOT compatible with 2S (7.4V) or 4S (14.8V) devices.

Use only a balance charger designed for 3S (11.1V) Li-ion/Li-Po batteries. Steps:
1. Set charger to Li-Po mode with 3S selected — full charge voltage is 12.6V
2. Recommended charge current: 2.0A (1C maximum)
3. Connect BOTH plugs to the charger:
- SM-2P (2-pin): Main discharge/power connector
- XH-4P (4-pin): Balance connector
4. Never charge without connecting the balance plug — this may cause cell imbalance
5. Never leave the battery unattended while charging
6. Do not discharge below 9.0V (3.0V per cell)

The XH-4P balance plug is essential for keeping all three cells at equal voltage, maximizing battery lifespan.

For maximum lifespan (300-500 cycles):
1. Always balance charge using both SM-2P and XH-4P plugs
2. Do not discharge below 9.0V (3.0V per cell)
3. Store at 3.8V per cell (11.4V total) at room temperature
4. Allow the battery to cool before recharging after use
5. Never leave the battery unattended while charging
6. Avoid physical damage to the battery wrap
7. If the battery swells, becomes hot, or shows damage, stop use immediately

This 3S 18350 pack delivers 2000mAh capacity — ideal for extended RC toy runtimes. Balance charging every cycle is the single most important factor for battery longevity.
