Frequently Asked Questions

This 903462 2S Li-Po battery is specifically designed for the K70 RC drone and K70 RC helicopter. It features a 4mm Banana Plug (bullet connector) and measures 69×35×17.5mm. Please verify your drone's battery compartment size and connector type before ordering. This battery is NOT compatible with devices using JST, SM, EC2, EC3, XT30, or XT60 connectors unless adapted (adapter not included). For reference, similar 2S 2000mAh batteries on AliExpress sell for $8-14, and Amazon for $12-18.

The Banana Plug (also called bullet connector) is a 4mm diameter cylindrical connector commonly used in RC models for high-current applications. It provides a secure push-in connection with low resistance. To use:
- Positive (red wire) plugs into the positive socket on your drone/charger
- Negative (black wire) plugs into the negative socket

This battery has two separate Banana Plugs (one red, one black). When charging, connect both plugs to a compatible 2S Li-Po charger with banana plug ports. Always connect positive to positive, negative to negative. This connector type is known for its reliability and high current handling (up to 50A continuous).

Use only a balance charger designed for 2S (7.4V) Li-Po batteries with banana plug ports or appropriate adapter cables. Set charger to Li-Po mode with 2S selected — full charge voltage is 8.4V (4.2V per cell). Key guidelines:
- Recommended charge current: 2.0A (1C maximum)
- Balance charging is recommended for cell health
- Never leave the battery unattended while charging
- Do not discharge below 6.0V (3.0V per cell)
- For storage (over 7 days), charge/discharge to 3.8V per cell (7.6V total)
- Store at room temperature away from direct sunlight

If the battery swells or becomes hot during charging or use, stop immediately and recycle properly.
