Zeee Batteries 14.8 V (4S)

Overview

Zeee 14.8 V (4S) LiPo packs provide a meaningful step up in acceleration and top speed when your ESC and motor are rated for 4S. They hold voltage well under load, helping 1/8 buggies/truggies, speed-run builds, boats, EDF jets, and performance quads maintain pace late in a run.

When to Choose 4S

• Use if you want higher top speed and stronger mid‑throttle authority without jumping to heavier, hotter 6S setups.
• Use for 1/8 off-road racing, speed runs under 120 mph, offshore hulls on moderate props, and 4S freestyle/long‑range quads.
• Avoid if your electronics are not 4S‑rated, or if class rules mandate lower voltage. Consider 3S for tighter tracks or light aircraft where weight is critical; consider 6S only if your platform and electronics are built for it.

Picking the Right Zeee 4S Pack

1. Confirm compatibility: ESC, motor, and drivetrain must be 4S‑capable.
2. Capacity vs. weight: Choose the smallest capacity that completes your run with a buffer. Extra mAh adds weight and can slow handling.
3. C rating: High‑draw boats, EDFs, and speed runs benefit from higher C headroom to reduce sag and heat.
4. Case type: Hardcase for RC cars (impact and abrasion resistance); softcase for aircraft and quads (lower weight, easier fitment).
5. Connector: Match your ESC to avoid adapters. XT90/EC5 for high current; XT60 for moderate current. Minimize adapter chains to reduce resistance and heat.

Setup Tips for Speed and Safe Temps

• Gearing: Start conservative (1–2 teeth smaller pinion than your 3S baseline). Add speed gradually after checking temps across a full run.
• Thermal targets: Aim for motor ≤ 170°F (77°C), ESC ≤ 150°F (65°C), pack ≤ 130°F (54°C). If hotter, gear down, reduce timing/punch, or add cooling.
• Timing & punch: Reduce motor timing when moving to 4S; use ESC punch control to prevent current spikes and wheelspin.
• Cooling: Add fans/heat sinks for cars; ensure clear airflow in boats/EDFs; avoid enclosing packs in airtight compartments.

Charging and Care

• Balance charge every time at the pack’s rated charge rate (1C is a safe default unless Zeee specifies otherwise).
• Storage: Store at 3.75–3.85 V per cell in a cool, dry place. Do not store fully charged or fully depleted.
• Cutoff: Set LVC around 3.4–3.5 V per cell under load; avoid resting below ~3.7 V per cell for longevity.
• Safety: Charge on a non‑flammable surface, in a LiPo bag or fire‑safe container. Never charge unattended. Discontinue use if the pack is puffed, damaged, or hot after rest.

Quick Runtime Estimates

Runtime (minutes) ≈ (Capacity mAh ÷ 1000) ÷ Average Current (A) × 60.

• 1/8 buggy example: 5000 mAh at 40 A average ≈ 7.5 minutes.
• 5" quad example: 1500 mAh at 20 A average ≈ 4.5 minutes.

Common Mistakes to Avoid

• Over‑gearing: Causes heat soak and early cutoffs. If temps rise quickly, gear down.
• Adapter chains: Extra connectors add resistance and heat. Use the correct plug on the pack/ESC.
• Oversized capacity: Heavier packs hurt handling and can run hotter. Pick the smallest pack that meets your target time.
• Poor mounting: Prevent movement and chafing; avoid sharp edges and squeeze points that can damage softcase packs.

Alternatives and Compatibility Notes

• 3S: Lighter and easier on drivetrains; less top‑end. Good for tight tracks and smaller aircraft.
• 6S: More performance but heavier and harder on components; only if your platform is designed for it.
• 2×2S in series: Works if both packs are identical, well‑matched, and balanced. Mix‑matching ages/capacities can cause imbalance.

FAQ

Will 4S damage my system?

No, provided your ESC and motor are rated for 4S and you manage gearing, timing, and cooling. Always verify manufacturer specs.

Hardcase or softcase for my use?

Hardcase for ground vehicles to resist impacts and abrasion. Softcase for aircraft and quads to save weight and improve fitment.

What connector should I choose?

Match your ESC. Use XT90/EC5 for high‑current car/boat setups; XT60 for moderate‑draw and quads. Avoid multiple adapters.

How do I know if my gearing is safe?

Run a full‑length session, then measure temps immediately. If any component exceeds the targets above, reduce pinion size or prop load and retest.

How should I store the pack between race days?

Balance to 3.75–3.85 V per cell and store cool and dry. Check voltage monthly and re‑storage‑charge if needed.
