Overview
This OVONIC combo includes 2 x 5200mAh 2S (7.4V) 50C hardcase LiPo battery packs with EC3 plug, plus a LiPo voltage checker (voltage tester buzzer alarm). Designed for RC cars, trucks, boats, and some airplanes, it provides extended runtime while keeping a compact, hardcase format suitable for demanding RC use.
Key Features
- 2S 7.4V LiPo power with 50C discharge: Suitable for high-current RC applications using a 2S setup.
- Hardcase protection: Helps protect the cells during RC use on rough terrain.
- EC3 main connector + JST-XHR-3P balance lead: Common connection types for 2S LiPo charging and installation.
- 12 AWG leads: Built with 12 AWG wire.
- Voltage checker included: Monitors cell voltage and provides a low-voltage alarm; stated compatibility for 2S to 8S LiPo batteries.
- OVONIC stacking technology claims: Higher energy density (+6%), longer running time (+12%), lower battery swelling (-8%), lower internal resistance (-4%) versus winding technology.

- ARRMA Granite 4x4 Mega (may need an EC3 to IC3 adapter)
- ARRMA Senton 4x4 Mega
- Losi Tenacity SCT
- Losi Baja Rey 1/10 Desert Truck
- ECX Ruckus 1/10 Monster Truck
- ECX Torment 1/10 SCT
- ECX Circuit 1/10 Stadium Truck
- Redcat Racing Blackout XTE
- Redcat Racing Volcano EPX
- Pro Boat Recoil 17
- Pro Boat Shockwave 26
- Pro Boat Blackjack 24
- Pro Boat Stealthwake 23
- E-flite Apprentice S 15e
- HobbyZone Carbon Cub S+ 1.3m
- E-flite Timber X 1.2m
Note: Some TRA models use TRA ID connectors, so an EC3-to-TRA adapter is required.

Voltage Checker Notes
- Low-voltage alarm: alerts when voltage drops below 3.2V per cell (stated).
- Storage guidance: helps check for 3.8V per cell storage voltage (stated).
- Stated compatibility: 2S to 8S LiPo batteries.
Charging & Safety Notices
- Only use the battery if the voltage and plug match the RC model.
- Stop charging immediately when a cell reaches 4.2V (normal cell voltage: 3.7V to 4.2V).
- Inspect the battery condition and confirm voltage is normal before use.
- If a new battery will not hold a full charge or loses charge quickly, use a balance charger to charge and recycle several times.
Details
Hardcase 2S LiPo power for 1/10–1/8 RC setups, with EC3 connector, 12AWG wire, and a compact 139×47.4×25.4mm footprint.
The bundle includes two 5200mAh packs plus a LiPo voltage checker buzzer to help monitor cell voltage before and after runs.
Match voltage, dimensions, and connector type to your model to confirm fit—ideal for many RC cars, trucks, boats, and select airplanes using 2S power.
