Venom Batteries 11.1 V (3S)

Venom 11.1 V (3S) LiPo Batteries

Venom 3S packs offer a practical boost in power over 2S for drivers and pilots who want sharper throttle response and higher top speed while keeping control and handling predictable. They are commonly used in 3S-capable RTR cars and trucks, small to mid-size boats, park flyers, and freestyle FPV quads.

When to Choose 3S

• Use 3S if your model feels underpowered on 2S and your ESC/motor are rated for up to 12.6 V.
• Good match for stadium trucks, short-course trucks, buggies, small hull RC boats, and beginner-to-intermediate FPV quads.
• Avoid 3S if your system is 2S-only, the drivetrain runs hot on 2S, or space/weight limits are strict (micro models).

How to Select the Right Pack

1. Fit and weight: Measure the battery tray (length × width × height) and check your model’s recommended weight. Hard-case packs suit cars/trucks; soft packs save weight for air.
2. Capacity (mAh): Higher mAh increases runtime but adds weight. Typical ranges: cars 4000–6000 mAh; boats 2200–5000 mAh; park flyers 1500–3000 mAh; FPV quads 850–1500 mAh (3–4 inch) or 1300–2200 mAh (light 5 inch).
3. C rating (current capability): Continuous current ≈ Capacity (Ah) × C. Example: 5000 mAh (5 Ah) × 50C ≈ 250 A. Choose higher C for high-draw setups (boats, heavy props, big tires).
4. Connector: Venom’s universal plug system uses swappable tips. Match your ESC connector (e.g., XT60, EC3/EC5, Deans/T‑Plug, Traxxas) and avoid stacking adapters.

Quick Picks and Typical Runtime

Runtime varies with gearing/prop load, surface/conditions, and throttle use. Stop with 20–30% charge remaining to protect the pack.

Setup and Tuning on 3S

• Gearing: When moving from 2S to 3S in cars, reduce pinion by ~10–20% to keep temps in check.
• ESC settings: Enable LiPo mode and set low-voltage cutoff to about 3.3–3.5 V per cell (9.9–10.5 V for 3S). Boats benefit from the higher end (3.5 V/cell).
• Throttle/punch: Add throttle expo or reduce punch to protect drivetrains on low-grip surfaces.
• Temperature targets: Aim to keep the battery under ~120°F (49°C) and the motor/ESC under ~160°F (71°C). If hotter, reduce gearing or prop load.

Charging and Care

• Charge rate: Balance-charge at 1C unless your pack clearly specifies a higher safe rate. A 5000 mAh pack at 1C takes ~60–75 minutes from near empty.
• Storage: Store at 3.75–3.85 V per cell (about 11.3–11.6 V for 3S).
• Handling: Inspect for swelling, damage, or frayed leads. Secure packs with straps/foam to prevent movement and vibration.
• Safety: Charge on a nonflammable surface, in a LiPo-safe bag, and never unattended. Keep packs dry; do not puncture or crush. Recycle damaged or puffed packs per local e‑waste guidelines.

Compatibility and Connectors

• Verify your ESC/motor ratings for 3S (12.6 V max). Many modern brushless RTRs support 3S; many brushed systems do not.
• Use the correct Venom universal plug tip for your ESC to minimize resistance and heat. Choose connector types sized for your current draw (e.g., XT60/EC3 for moderate, EC5/XT90 for higher current).

Alternatives

• 2S: Easier to manage heat and traction; good for beginners, tight tracks, and smaller models.
• 4S: For speed runs and heavy boats; requires drivetrain upgrades and careful gearing/prop selection.
• NiMH: Simpler charging and handling, but heavier with lower power density compared to LiPo.
