Ovonic Batteries 22.2 V (6S)

Overview

Ovonic 22.2 V (6S) LiPo batteries provide high-voltage power for demanding RC platforms. Six series cells deliver 22.2 V nominal and 25.2 V when fully charged, helping you achieve target speed and thrust with lower current than 4S for the same power. This can reduce heat and voltage sag when your setup is properly matched.

Choose 6S if

• Your ESC, motor, and servos are explicitly rated for 6S (or higher).
• You need strong punch and sustained output for 1/7 RC cars, large offshore boats, EDF jets, or heavy-lift multirotors.
• You want to reduce current draw and wiring stress compared with lower-voltage setups at similar power.

Consider alternatives if

• Weight is critical (small aircraft may fly better on 4S).
• Your electronics are not 6S-capable.
• You are targeting extreme power levels beyond what one pack can safely supply—consider 8S with appropriate gear instead.

How to Select the Right Ovonic 6S Pack

• Compatibility: Verify 6S ratings for ESC, motor KV, and BEC/receiver. Check battery tray dimensions and strap spacing.
• Capacity (mAh): Higher capacity increases runtime but adds weight. Common 6S capacities range from 3300–8000 mAh.
• C Rating: Estimate your current draw and target a continuous rating with headroom. A conservative rule is to use no more than ~50–70% of the printed continuous rating during sustained use.
• Connectors & Wire: Use high-current plugs (XT90, EC5/IC5, QS8 for very high current) and appropriate wire gauge (10–12 AWG for most 6S car/boat/EDF setups).
• Form Factor: Hardcase packs suit surface RC; softcase packs save weight for air. Match your platform’s mounting method.
• Series/Parallel: Two matched 3S packs in series can substitute for one 6S; keep brand, capacity, age, and cycle count the same.

Example current targets (guidelines)

Platform	Typical avg/burst current	Suggested capacity	Target continuous rating
1/7 RC car	40–80 A avg / 150–250 A burst	5000–8000 mAh	≥ 200 A cont (e.g., 5000 mAh × 40C)
Offshore boat	60–120 A avg / 180–300 A burst	5000–8000 mAh	≥ 240–300 A cont (e.g., 6000 mAh × 40–50C)
EDF jet	60–100 A avg / 120–180 A burst	3300–6000 mAh	≥ 180–240 A cont (e.g., 4000 mAh × 45–60C)

Note: Printed C ratings vary by model and can be optimistic. Build in headroom and monitor temps on initial runs.

Runtime Estimates

Runtime (minutes) ≈ (Capacity in Ah × 60 × 0.8) ÷ Average Amps. The 0.8 factor reserves about 20% to protect the pack.

• 5000 mAh (5 Ah) at 40 A avg → ~6 minutes (5 × 60 × 0.8 ÷ 40)
• 6000 mAh (6 Ah) at 60 A avg → ~4.8 minutes
• 8000 mAh (8 Ah) at 45 A avg → ~8–9 minutes

Setup Tips by Platform

RC Cars (1/7 and heavy 1/8)

• Start with conservative gearing; increase gradually while keeping motor under ~180°F (82°C) and ESC under ~160°F (71°C).
• Use high-current connectors (XT90/EC5) and short leads to reduce voltage drop.
• Set LVC around 3.3–3.5 V/cell under load to prevent over-discharge.
• Secure the pack firmly; add foam to prevent vibration and case wear.

Offshore Boats

• Prop for current, not just speed; make small pitch/diameter changes and recheck temps.
• Ensure cooling lines are clear; keep ESC and motor at safe temps after full-throttle passes.
• Use corrosion protection on connectors; keep packs dry and well-secured.

EDF Jets & Heavy-Lift Multirotors

• Balance thrust and weight: a lighter 3300–5000 mAh pack can improve handling versus a heavier 6000–8000 mAh pack.
• Match motor KV and fan/prop load to 6S; recalibrate ESC throttle range.
• Confirm CG with the chosen pack; use straps and non-slip pads.

Charging, Storage, and Safety

• Balance charge at 1C unless the specific pack supports higher rates.
• Never leave charging unattended; use a LiPo-safe bag or fire-resistant surface.
• Allow packs to cool to ambient before charging; avoid charging hot packs.
• Storage: 3.75–3.85 V per cell (~22.5–23.1 V total) in a cool, dry place.
• Do not puncture, crush, or continue to use swollen or damaged packs.
• Inspect leads and balance plugs regularly; replace worn connectors.

Compatibility Notes

• Voltage: 6S is 22.2 V nominal, 25.2 V full. Confirm ESC and motor ratings; many car setups pair 6S with ~1600–1900 KV motors.
• Connectors: XT90/EC5 are common on 6S. Consider QS8 for sustained currents above ~150 A. Avoid undersized plugs (e.g., Deans) for high-current use.
• Wiring: 10–12 AWG silicone wire is typical for high-current 6S applications.
• Series use: If running 2×3S in series, packs must match brand, capacity, age, and state-of-charge.

FAQ

Is 6S overkill for my setup?

It depends on ratings and goals. If your electronics support 6S and you need high power with reduced current, 6S is appropriate. If weight or component limits are concerns, consider 4S.

Can I use two 3S packs instead of one 6S?

Yes. Wire two identical 3S packs in series (same brand, capacity, age, and cycle count). Always balance charge them separately and keep them paired.

What connectors work best on 6S?

XT90 and EC5/IC5 are suitable for most 6S use. For very high current, QS8 or similar large anti-spark connectors reduce arcing and heat.

How should I set low-voltage cutoff?

For 6S, an LVC of about 3.3–3.5 V per cell under load helps protect the pack. Stop use if you notice power sag before LVC.

What is the correct storage procedure?

Balance charge/discharge to 3.75–3.85 V per cell, store in a fire-resistant container, and check monthly. Avoid heat and full-charge storage.

Summary

Ovonic 22.2 V (6S) LiPo batteries offer strong, consistent power for high-demand RC applications when matched with 6S-capable electronics. Size your pack for current and runtime, use robust connectors, and follow LiPo safety to get reliable performance run after run.
