Overview
The OVONIC 4S LiPo Battery (2-pack) is a 14.8V 9000mAh LiPo battery set with a 130C continuous discharge rate for high-power RC use. Each pack uses an EC5 discharge plug and a JST-XHR-5P balance/charge plug, and is sized for many RC cars, trucks, boats, and other RC models where 4S voltage and EC5 fitment are required.
Key Features
- High output: 130C continuous discharge rate; 260C max burst discharge rate.
- High capacity: 9000mAh for longer runtimes between charges.
- 4S configuration: 4S1P, 14.8V.
- Connectors and wiring: EC5 discharge plug, JST-XHR-5P balance/charge plug, 12AWG wire gauge.
- Stacking technology (as described): higher energy density (+6%), longer running time (+12%), lower battery swelling (-8%), lower internal resistance (-4%).
- Cycle life claim: stacking process stated to extend life up to 350 times.

Applications
- RC cars and trucks (including 1/5, 1/7, 1/8, 1/10 scale models where size and connectors fit)
- RC boats
- Other RC models that accept a 4S (14.8V) LiPo with EC5 connector and suitable battery bay dimensions
Fitment note: Match voltage, dimensions, and plug type with the RC model’s battery compartment and power system before purchase.
Charging & Safety Notes
- Use a compatible balance charger for 4S LiPo batteries (JST-XHR-5P).
- Stop charging when any cell reaches 4.2V per cell (normal range: 3.7V–4.2V per cell).
- Inspect the battery condition before each use and compare dimensions with the original battery for proper fit.
- If a new battery does not hold a full charge or loses charge rapidly, use a balance charger and cycle it several times.

Details

Sized at 175 × 49 × 39mm, each 4S 14.8V pack uses an EC5 discharge connector plus a JST-XHR-5P balance plug with 12AWG leads.

Stacking-process construction is highlighted for higher energy density and longer runtime with reduced swelling and lower internal resistance versus standard winding designs.


Match voltage, battery bay dimensions, and the EC5 connector to your RC setup for proper fit in cars, trucks, boats, and other 4S models.

Includes two 4S 9000mAh packs plus the packaging box, user manual, and Ovonic brand stickers.
