2-Pack OVONIC 15.2V 6000mAh 140C 4S LiHV Hardcase LiPo Battery Pack with 5mm Bullet to EC5 Plug for 1/5 Scale RC Cars, Drag Racing & 8S Rigs

Overview

High-voltage drag racing builds, speed-run cars, and heavy-duty 1/5 scale bashers demand explosive punch, minimal internal resistance, and maximum voltage maintenance under load. Standard 14.8V LiPo packs can experience voltage depression during extreme acceleration, limiting top-end speed and launch power.

OVONIC 15.2V 6000mAh 140C 4S1P LiHV Hardcase Battery Pack utilizes High Voltage (LiHV) cell chemistry to deliver a higher nominal voltage of 15.2V (4.35V per cell fully charged), providing sharper throttle response, higher motor RPM, and increased burst power over standard 4S packs. Built in a robust 4S1P hardcase configuration, featuring a massive 140C continuous discharge rate (280C burst), and low-resistance 5mm bullet-to-EC5 connectors, this 2-pack combo is ideal for dedicated 4S drag racing setups, 1/5 and 1/6 scale platforms, or running two packs in series for extreme 8S (30.4V nominal) speed builds.

Primary Applications & Compatibility

Requires a 4S (15.2V LiHV) setup or a dual-pack 8S (30.4V LiHV in series) power system with EC5 connectors and a battery tray accommodating 138 × 48 × 47 mm:

• 1/5 & 1/6 Scale Monster Trucks & Bashers (Configured in Series for 8S): Ideal for running two packs in series to power 8S platforms including the ARRMA Kraton 8S BLX, ARRMA Outcast 8S BLX, and LOSI Super Baja Rey.

• No-Prep RC Drag Racing & Speed Runs: Delivers maximum instant amperage and higher peak voltage for 4S drag racing setups and speed-run cars where instant launch velocity is critical.

• Large-Scale 4S Surface Vehicles: Fits 1/8 to 1/5 scale buggies, trucks, and truggies requiring a high-current, impact-resistant 4S hardcase battery.

Key Features

• High-Voltage LiHV Chemistry (15.2V Nominal): Delivers higher energy density and a higher peak charge voltage (up to 4.35V/cell) for higher top speed and reduced voltage sag compared to standard 14.8V LiPos.

• 140C Continuous / 280C Burst Discharge: Engineered for instant power delivery during hard launches, drag racing starts, and high-torque maneuvers.

• Impact-Resistant Hardcase Shell: Rugged plastic hardcase protects cells against chassis impacts, roll-overs, and off-road debris in large-scale vehicles.

• 5mm Bullet to EC5 Connector System: Direct 5mm internal bullet sockets with an included heavy-duty EC5 adapter lead minimize connection resistance for maximum current flow.

• 6000mAh 4S1P Capacity Reserve: Provides extended runtimes and consistent voltage output throughout long race mains and bashing sessions.

Safety & Operating Guidelines

• ESC & Voltage Verification: Ensure your ESC supports High-Voltage LiHV chemistry and input voltages up to 17.4V fully charged per pack (or 34.8V when two packs are used in series for 8S).

• LiHV Charging Mode: Charge using a LiHV-compatible balance charger set specifically to LiHV mode (4.35V per cell maximum cutoff). Standard LiPo charge mode will undercharge the battery to 4.20V per cell.

• Bullet Plug Maintenance: Ensure 5mm bullet connectors fit snugly into the battery ports. Clean ports regularly to prevent dirt buildup and resistance spikes.

• Low-Voltage Cutoff: Set ESC Low-Voltage Cutoff (LVC) to at least 3.4V to 3.5V per cell to prevent over-discharging.

• Storage Charge: Store batteries at 3.80V to 3.85V per cell in a cool, dry place inside a fire-retardant LiPo bag when not in use for more than 48 hours.
