Overview
This OVONIC 3S LiPo battery bundle includes 2 x 11.1V 5200mAh 120C packs with an EC5 plug, plus a LiPo voltage checker/buzzer alarm for monitoring cell voltage. It is designed for RC cars and trucks (including 1/8 and 1/10 scale applications) that require a 3S (11.1V) LiPo pack and matching connector/fitment.
Key Features
- 3S (11.1V) / 5200mAh / 120C rated pack for high-load RC power systems.
- EC5 main connector and JST-XHR-4P balance connector.
- 12 AWG lead wire.
- Cell-voltage monitoring: the included voltage checker can be used to monitor each cell and provide a low-voltage alarm (stated alert threshold: 3.2V per cell).
- Charging/storage guidance (stated): stop charging when a cell reaches 4.2V; typical cell voltage range is 3.7Vâ4.2V; suggested storage voltage is 3.8V per cell.
- Manufacturer technology comparison (stated): âStacking Technologyâ is presented with +6% higher energy density, +12% longer running time, -8% lower battery swelling, and -4% lower internal resistance versus âWinding Technologyâ.

For help confirming connector type, battery dimensions, or basic LiPo use guidance before ordering, contact https://rcdrone.top/ or email [email protected].
Usage Notes
- Fitment depends on matching voltage, plug type, and available battery tray space.
- Stop charging immediately when any cell reaches 4.2V (stated normal cell voltage range: 3.7Vâ4.2V).
- Inspect the battery and verify voltage is normal before first use.
- If a new battery will not hold a full charge or loses charge quickly, use a balance charger and cycle it several times (stated).
Details

Built for high-load RC power systems, each 3S 5200mAh pack uses an EC5 connector, JST-XHR balance lead, and 12AWG wires for solid current handling.

OVONICâs listed âstacking technologyâ claims gains in energy density and runtime with reduced swelling and internal resistance versus winding designs.

A quick visual comparison outlines the brandâs stated performance targets across discharge capability, cycle life, safety, and internal resistance.


The bundle includes two 3S 11.1V 5200mAh 120C packs plus a cell-voltage checker/buzzer alarm for easy voltage monitoring between runs.
