Overview
The Ovonic 3500mAh 2S1P 25C LiPo battery 2-pack is a lightweight 7.4V power solution for RC cars where balance, handling, and suspension response matter. Each pack uses an XT60 main connector and includes XT60 to TRA adapters for Traxxas-style compatibility.
Designed with internal aluminum plates for added structural integrity, these packs are built for reliable power delivery and quick battery swaps during RC sessions.
Key Features
- Lightweight 2S1P design: supports better vehicle balance and handling for 1/10 and 1/12 scale platforms.
- 25C discharge rate: stable output for hobby driving.
- Connector setup: XT60 plug on the battery; includes XT60 to TRA adapters.
- Balance lead type shown: JST-XHR-3P.
- Wiring: solid copper wire (as labeled).
- Cycle-life / cell characteristics (as labeled): cycle life 350+ times; high energy density 128 Wh/L; micro internal resistance < 5 mΩ.
