Venom 22.2 V (6S) LiPo Batteries

Venom 6S (22.2 V nominal, 25.2 V fully charged) LiPo packs deliver stable, high-voltage power for heavy-duty RC builds. They’re a strong match for 1/7–1/8 scale cars, large offshore boats, EDF jets, and heavy-lift multirotors where lower current draw and consistent output matter.

When to Choose 6S

• Use if you need higher speed, thrust, or torque without pushing extreme current through your ESC and wiring.
• Use for long full-throttle pulls where voltage sag can make or break performance (e.g., speed runs, EDF passes, offshore straightaways).
• Avoid if your ESC, motor, or drivetrain is not rated for 6S voltage, or if the battery bay cannot accommodate the size/weight.

Compatibility Checklist

• ESC rating: Must be 6S capable with an appropriate low-voltage cutoff (LVC) setting.
• Motor kv/prop/gearing: Select kv and gearing or prop pitch/diameter to keep current and temps in range on 6S.
• Connector & wire gauge: High-current plugs (EC5/IC5, XT90, QS8 for extreme loads) and 10–12 AWG leads are common on 6S builds.
• Physical fit: Verify length, width, height, and weight against your tray or battery bay.
• Charger: Use a 6S-capable balance charger; balance lead is typically JST‑XH (7‑pin for 6S).

How to Choose a Venom 6S Pack

1. Capacity (mAh): Higher capacity extends runtime but adds weight. For example, a 5000 mAh pack suits many 1/7 on-road and EDF setups; larger boats and heavy-lift rigs may prefer 6000–8000 mAh.
2. C rating (discharge): Choose a C rating that comfortably exceeds your expected peak and average current. For high-demand setups, prioritize higher C for reduced sag and heat.
3. Dimensions & weight: Ensure the pack fits your compartment and does not upset balance/CG (critical in aircraft).
4. Connector type: Match your ESC plug; upgrade if needed to reduce resistance and heat.
5. Case style: Hardcase helps protect packs in ground vehicles; softcase saves weight in aircraft and drones.

Runtime Planning

Estimate runtime using your average current draw:

• Formula: Runtime (min) ≈ (Capacity mAh ÷ 1000) ÷ Avg Current (A) × 60
• Example: 5000 mAh on a 40 A average ≈ (5 ÷ 40) × 60 = 7.5 minutes
• Expect shorter runtimes for high-throttle driving, large props, or heavy craft.

Setup Tips

• Start with conservative gearing/prop pitch and increase gradually while monitoring temps.
• Secure the pack firmly with straps and foam to prevent movement and lead strain.
• After a shakedown run, check motor/ESC/battery temps; aim to keep the pack under 140°F (60°C).
• Use telemetry or a watt meter to verify current draw and voltage sag under load.

Safety and Care

• Charge: Balance charge at ≤1C unless the pack is specifically rated for higher. Example: 5000 mAh → ≤5 A.
• Voltage: Full 4.20 V/cell (25.2 V pack). Storage 3.75–3.85 V/cell (22.5–23.1 V pack). Avoid resting below ~3.5 V/cell; set ESC LVC around 3.4–3.5 V/cell.
• Temperature: Do not charge hot or cold. Charge around 50–77°F (10–25°C). Stop use if the pack swells or exceeds safe temps.
• Inspection: Check for damage, puffing, or abraded wires before each use. Replace compromised packs.
• Storage/transport: Store at 30–60% charge in a fire-resistant container, away from metal objects and direct sun.

Alternatives

• Two 3S in series: Can form a 6S system; use identical, equally aged packs and charge separately.
• Lower voltage (4S/5S): Consider for lighter platforms or if your electronics are not 6S-rated.

Pros and Cons of 6S

• Pros: Higher voltage with lower current for the same power, reduced heat, stronger acceleration, steadier voltage during long pulls.
• Cons: Heavier packs, tighter fitment, requires 6S‑rated electronics, may need gearing/prop changes.

FAQ

Will a 6S battery damage my RC?

It can if the ESC, motor, and drivetrain are not rated for 6S. Check voltage ratings and adjust gearing/prop to keep current and temperatures in a safe range.

What connector should I use?

High-current plugs such as EC5/IC5, XT90, or QS8 are recommended for 6S applications. Avoid undersized connectors that overheat under load.

How fast can I charge a 6S pack?

Unless the pack specifies a higher rate, charge at 1C (capacity in Ah equals amps). Always balance charge and never leave charging unattended.

What low-voltage cutoff should I set?

Many users set 3.4–3.5 V per cell under load to preserve pack health. For 6S, that’s roughly 20.4–21.0 V pack LVC.

Hardcase or softcase?

Hardcase protects against impacts in cars and trucks. Softcase is lighter and fits better in aircraft and drones where weight and CG are critical.
