OVONIC 3S 11.1V 5000mAh 120C LiPo Battery 2-Pack w/ XT60-to-TRA Adapter & Voltage Checker

Overview

This OVONIC LiPo battery combo includes 2 x 3S (11.1V) 5000mAh packs rated at 120C, plus XT60-to-TRA adapters and a LiPo voltage checker buzzer alarm. The 3S1P 11.1V (55.5Wh) configuration is designed for RC models that need strong discharge capability and stable power delivery, including many RC cars, trucks, boats, airplanes, and helicopters.

Key Features

• High discharge rate: 120C for responsive acceleration and throttle feel in high-draw RC setups.
• Capacity for longer runtime: 5000mAh per pack.
• Connectors and wiring: XT60 main connector, JST-XHR-4P balance lead, and 12 AWG wire.
• Included voltage checker: LiPo voltage tester buzzer alarm helps monitor pack voltage and avoid over-discharge.
• Manufacturer-stated cell construction comparison: Stacking technology is presented as +6% higher energy density, +12% longer running time, -8% lower battery swelling, and -4% lower internal resistance (compared against “winding technology/others”).
