This pack serves three 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
• 1/14 – 1/16 scale RC cars: trucks and buggies on a 3S power system (H16GT, H16DR, H16BM, H14BM, 14301, 14302 class)

At 88 × 35 × 28mm and 170g, it fits the battery bays of all three. The Deans T plug is a locking connector that resists accidental disconnection under vibration — a real advantage on 350 helis doing aggressive aerobatics and on RC cars hitting jumps and hard corners.

Before ordering, verify:

• Battery bay clearance: at least 88 × 35 × 28mm (including Deans T plug clearance)
• ESC rated for 3S 12.6V max input
• Charger outputs 12.6V (3S mode)
• ESC accepts a Deans T plug (or use an adapter)

This pack is not designed for 2S or 4S systems, 450+ class helis, or 5" FPV quads.

• 35C continuous: sustained 77A (2.2Ah × 35C) — the current this pack can deliver indefinitely without overheating
• 70C peak: burst 154A (2.2Ah × 70C) — short-duration spikes (under 5 seconds)

For a 350-class heli in aggressive aerobatics (hover, loops, inverted): typical sustained draw is 30–55A, with momentary peaks of 80–100A.

For a 1.2m sport trainer at full throttle: typical sustained draw is 20–45A.

For a 1/14 scale truck on a 3S system: typical sustained draw is 25–60A, with launch spikes of 80–120A.

77A continuous sits above the sustained draw of all three platforms. The 154A peak covers launch and punch-out spikes. You will not hit the battery’s limit in normal operation on any of these platforms.

Both are valid 3S connectors, but they serve different use cases:

• XT60: open connector, most common in 3S fixed-wing and general RC aircraft. Easy to plug/unplug, but no locking mechanism.
• Deans T: locking connector with a spring-loaded latch. Once plugged in, it stays in unless you deliberately press the release tab. This matters when:Your 350 heli is doing aggressive aerobatics and vibration could loosen an open connectorYour RC car is hitting jumps, hard corners, and rough terrain where an XT60 could work loose

If your ESC uses XT60 or another plug, a Deans T-to-X adapter solves it. But if your ESC already has a Deans T socket (common on 350 heli ESCs and 1/14 car ESCs), this is the native connection.

Practical tip: if you fly both a 350 heli and a 1.2m airplane, you’ll want one Deans T pack for the heli and one XT60 pack for the airplane — or just run adapters on the airplane side.

• 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 350 heli and fixed-wing sessions, 1C is the correct choice. For RC car sessions where you’re doing repeated high-current launches, 1C is also preferred to keep the cells healthy between runs.

With 24.4Wh of energy per pack, typical endurance:

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

1.0m–1.5m fixed-wing (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.

1/14 – 1/16 RC car (3S power system): 5–12 minutes per run depending on track type. Asphalt buggies at full throttle trend toward 5–7 min; off-road trucks at moderate throttle trend toward 8–12 min.

The 2-Pack in this listing gives you continuous operation: fly one, charge the other. At 1C, the charge cycle (50–60 min) overlaps with your flight time, so you’re never waiting more than a few minutes for the next pack.

For regular use, yes:

• 350 heli: 5–10 minutes of flight per pack, then 50–60 minutes of charging. With one pack, you fly 5 min, wait 55 min, fly 5 min, wait 55 min. With two packs, the wait drops to roughly the flight time itself.
• Fixed-wing: 12–20 minutes per pack. A 2-pack means you’re never on the ground waiting for a charge during a good field day.
• RC car: 5–10 minutes per run in a race or time-trial session. 2-pack keeps you on the track.
• Sharing: one pilot flies, the other charges. No queue.

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

• 2× PCEONAMP 11.1V 2200mAh 3S 35C LiPo battery, Deans T plug pre-soldered to 16AWG silicone leads
• 1× carton
• 1× user manual

The Deans T plug is factory-soldered. The 16AWG silicone leads are rated for 77A sustained (matching the 35C rating). The soft PVC wrap holds the 3 cells together and resists vibration from hard landings (heli), rough terrain (RC car), and repeated handling.

If your ESC uses a different connector (XT60, XT30, IC5, Deans non-T, etc.):

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

For most 350 heli ESCs and 1/14 RC car ESCs, Deans T is the native connector — no adapter needed.
