This pack is built for two main platforms:

• 350-class RC helicopters: single-rotor and coaxial (Align 350, Robinson 350, T-Rex 350 class)
• 1.0m–1.5m electric fixed-wing: sport trainers, aerobatic planes, scale models, electric gliders

At 90 × 35 × 27mm and 177g, it fits the battery bays of both platform types. The XT60 plug connects directly to standard 3S ESCs on both heli and airplane power systems.

Before ordering, verify:

• Battery bay clearance: at least 90 × 35 × 27mm (including XT60 plug clearance)
• ESC rated for 3S 12.6V max input
• Charger outputs 12.6V (3S mode)

This pack is not designed for 2S or 4S systems, 450+ class helis (insufficient capacity), or 5" FPV quads (wrong voltage class).

35C continuous means a sustained 77A (2.2Ah × 35C).

For a 350-class heli in aggressive aerobatics (hover, loops, inverted): typical sustained draw is 30–55A. For a 1.2m sport trainer at full throttle: typical sustained draw is 20–45A.

77A sits well above both, meaning the cells run cool and voltage stays flat throughout your flight. You will not feel sag or power loss during sustained high-throttle maneuvers.

If you’re running a 450-class heli or a 1.8m+ airplane that draws 60A+ sustained, a higher-capacity or higher-C pack would be a better match.

• Charger mode: 3S LiPo (4.20V/cell max, 12.6V total)
• Charge rate: 1C (2.2A) for daily use; 2C (4.4A) maximum for quick turnaround
• Balance voltage: 4.20V/cell
• Discharge cutoff: 3.50V/cell minimum (10.5V total) — do not fly below this
• Storage voltage: 3.80V/cell (11.4V) if not flying for more than 48 hours

At 1C (2.2A), a full charge from empty takes approximately 50–60 minutes. At 2C (4.4A), approximately 28–32 minutes.

Avoid sustained 3C+ (6.6A+) charging — it accelerates cell aging and reduces total cycle life. For most 350 heli and fixed-wing sessions, 1C is the correct choice since you’re not doing rapid pit swaps like in 5" FPV racing.

With 24.4Wh of energy per pack, typical endurance:

350-class heli (aggressive aerobatics, 800g–1.2kg AUW): 8–15 minutes per pack. Hover-heavy sessions will trend toward the upper end; sustained full-throttle aerobatics will trend toward the lower end.

1.0m–1.5m fixed-wing (sport trainer, 1.0–1.8kg AUW): 12–20 minutes per pack. Steady cruise at 60–70% throttle favors the upper end; aggressive aerobatic sequences favor the lower end.

These are planning estimates based on typical 3S motor and prop combinations. Actual flight time varies with your specific motor, prop, AUW, and throttle profile.

The 2-Pack in this listing gives you roughly 20–35 minutes of total flight time per charge cycle (one pack flying, one charging).

Yes, for practical field use:

• You fly one, charge the other. At 1C, a full charge takes 50–60 minutes. If you’re doing 10-minute flights, the 2-pack keeps you in the air continuously.
• 350 heli pilots do 5–8 flights per session. With a single pack, you’d be waiting 55 minutes between each flight. With two, the wait drops to roughly the flight time itself.
• If one pack is being charged or has a balance lead connected, the other is always ready.

For occasional flying (1–2 flights per session), one pack is sufficient. For regular field days or shared use, the 2-pack is the correct choice.

• 2× PCEONAMP 11.1V 2200mAh 3S 35C LiPo battery, XT60 plug pre-soldered
• 1× carton
• 1× user manual

The XT60 plug is factory-soldered to 16AWG silicone power leads. XT60 is the most common connector in the 3S RC aircraft and heli world — your ESC almost certainly accepts it directly.

If your setup uses a different plug (Deans, XT30, IC5, etc.):

1. Use an XT60-to-X adapter (no soldering, 10-second install)
2. Cut the XT60 and re-solder your preferred connector

For most 350 heli and 1.0m–1.5m fixed-wing builds, XT60 is the standard — no adapter needed.

They are electrically identical — same cells, same capacity (2200mAh), same voltage (11.1V 3S), same C-rate (35C), same dimensions (90 × 35 × 27mm), same weight (177g).

The only difference is the plug:

• This pack: XT60 (open connector, most common in 3S RC aircraft and heli)
• Deans T version: Deans T (locking connector, more common in RC cars and some heli ESCs)

Choose based on what your ESC accepts:

• If your ESC has an XT60 input → buy this pack
• If your ESC has a Deans T input → buy the Deans T version
• If you’re unsure → check your ESC manual or measure the socket

You can also buy either pack and use an adapter (XT60-to-Deans T or vice versa), but a matching plug is cleaner and eliminates one failure point.
