eTronix Series Battery Harness for 2 Packs – ET0706

The eTronix ET0706 series battery adaptor harness links two matching battery packs in series, delivering a higher voltage from your existing packs. This is ideal when you need to step up from, for example, a 2S to a 4S-equivalent system using two identical 2S packs, while keeping overall capacity (mAh) the same as a single pack.

Why Use a Series Adaptor

• Combine two matching packs in series to increase voltage for more speed and power potential.
• Maintains the capacity of a single pack while doubling nominal voltage.
• Useful where the ESC and motor are rated for higher cell counts.

Suggested Compatibility

Suitable for RC cars, trucks, boats, and aircraft that accept series battery configurations. Suggested compatibility depends on your connector type and available space; confirm your power system and connectors match before use.

Safety & Usage Notes

• Only use two packs of the same chemistry, capacity, C rating, age, and state of charge.
• Ensure your ESC, motor, and electronics are rated for the increased voltage.
• Do not charge packs while connected in series unless your charger specifically supports it.
• Verify polarity and secure all connections before powering the model.
