At 205 × 98 × 66mm and 2898g, this pack is built for large hexacopter (6-rotor) and octocopter (8-rotor) industrial drones with 12"–16" propellers — the type of platform used in long-endurance agricultural spraying, large-area mapping, border patrol, and extended surveillance missions.

The 32000mAh capacity and 10C (320A) rating position this as a long-endurance pack — it’s designed for platforms that fly for extended periods at moderate throttle rather than short bursts of maximum thrust. A 14" hexa at 60–75% cruise throttle is the ideal match.

Before ordering, verify:

• Battery bay clearance: at least 205 × 98 × 66mm
• Connector: AS150U on your ESC (or adapter)
• Voltage: ESC rated for 6S Ultra-HV 23.1V (27.3V max input)
• Charger supports 6S Ultra-HV mode (4.55V/cell)

10C continuous means a sustained 320A (32Ah × 10C).

For a large hexa with 12"–16" props and 100–350KV motors at 60–80% cruise throttle, typical sustained draw is 200–350A depending on AUW. This pack covers that range comfortably.

This is where this pack differs from a 25C pack: if your hexa needs to pull 400A+ at full throttle (e.g., a 16" octo with high-KV motors and a 10kg+ payload at max thrust), a 25C pack is the better match. If your mission profile is steady cruise for 40–60+ minutes rather than repeated full-throttle punches, this 10C / 32000mAh pack gives you significantly more flight time per charge.

Rule of thumb: check your logbook or flight controller telemetry. If your average sustained current draw across a typical mission stays below 300A, this pack is well-matched.

This is a 6S Ultra-HV pack — 3.85V per cell, 23.1V nominal, 27.3V full charge (4.55V/cell). It sits one tier above the standard HV platform:

• Standard 6S: 3.7V/cell, 25.2V full charge
• HV 6S: 3.8V/cell, 26.1V full charge
• Ultra-HV 6S (this pack): 3.85V/cell, 27.3V full charge

Charger requirement: You need a charger with a 6S Ultra-HV or 4.55V/cell profile. Most modern smart chargers (iCharger 208/306, SkyRC MA608, HOTA 1200) have this mode. If your charger only goes up to 4.35V/cell (6S HV), it will undercharge this pack by 0.2V per cell — roughly 5% capacity loss per charge cycle.

ESC requirement: Your ESC must be rated for at least 27.3V max input. Most 6S industrial ESCs (T-Motor 120A, EMAX 120A, Holybro 120A+) are rated 25.2V–30V and will handle it. If your ESC is strictly “25.2V max,” do not connect this pack.

Do not use this pack in a standard 6S (25.2V), HV 6S (26.1V), 4S, or 8S system.

• Charger mode: 6S Ultra-HV (4.55V/cell max, 27.3V total)
• Charge rate: 1C (32A) for daily field use; 2C (64A) maximum for mission turnaround
• Balance voltage: 4.55V/cell
• Discharge cutoff: 3.50V/cell minimum (21.0V total) — do not fly below this
• Storage voltage: 3.85V/cell (23.1V) if not flying for more than 48 hours

At 1C (32A), a full charge from empty takes approximately 60–70 minutes. At 2C (64A), approximately 35–40 minutes.

Avoid sustained 3C+ (96A+) charging. At 32Ah, the charge current is already high, and pushing beyond 2C significantly increases internal heat buildup and accelerates cell degradation. For a long-endurance mission profile where you’re not doing rapid battery swaps, 1C is the correct setting.

With 758.4Wh of energy and 320A continuous capability, here’s what to expect on a 12"–16" hexa:

• Agricultural spraying (10L–20L tank, 6–10kg AUW): 50–80 minutes at 60–75% cruise
• Large-area mapping / photogrammetry (4–7kg AUW): 60–90 minutes at steady throttle
• Border patrol / surveillance (5–8kg AUW): 50–75 minutes
• Heavy cargo (8–12kg AUW): 35–55 minutes

These are planning estimates based on 12"–16" props at 60–75% cruise throttle in calm conditions. Headwind, high altitude, and aggressive throttle usage will reduce endurance. A 16" prop on a 120KV motor at 70% throttle is the most efficient configuration and will trend toward the upper end of each range.

Practical planning rule: use 70% of the estimated endurance as your mission planning limit, leaving a 20–30% safety margin for the return leg and loiter time.

One plug is for discharge (connecting to your ESC), and the other is for charge (connecting to your charger). They are electrically isolated.

This design prevents a common field problem: accidentally discharging the battery while it’s connected to the charger, or plugging the wrong cable into the wrong port. With a single-plug design, you have to unplug the discharge cable before charging and remember to reconnect it after. With dual plugs, the discharge cable stays connected to the ESC at all times — you simply plug in the charge cable when needed and unplug it when done.

For a spraying operation where you’re swapping batteries every 50–70 minutes in the field, this saves time and eliminates the risk of forgetting to reconnect the discharge plug.

Both plugs are Amass AS150U gold-plated, anti-spark, with signal pin keying (physically prevents reverse-polarity connection). Rated for 400A+ sustained.

If your ESC uses a different connector (XT90S, Anderson, etc.):

1. Use an AS150U-to-X adapter on the discharge plug (no soldering)
2. The charge plug connects to your charger — most industrial chargers use an AS150U or Anderson input, so no adapter needed

Both packs fit the same class of large hexa, but they’re built for different mission profiles.

This pack (23.1V / 10C / 32000mAh / 758.4Wh) is the endurance pack. 32Ah at 10C gives you 758.4Wh of energy and 320A of continuous current. That’s enough for a 12"–16" hexa cruising at 60–75% throttle for 60–90 minutes. It’s the right choice for missions where flight time is the critical factor: long-range mapping, border patrol, extended surveillance, light-to-medium spraying where you’re not pulling maximum throttle.

The 22.8V / 25C / 23000mAh pack (524.4Wh, 575A continuous) is the power pack. 23Ah at 25C gives you 575A of continuous current. That’s the right choice when your hexa is loaded to 10kg+ and pulling 350–500A at full throttle: heavy spraying at max rate, cargo delivery with 8kg+ payload, or any mission where sustained high-thrust is the priority over flight time.

One practical difference to plan around: this pack charges to 27.3V (4.55V/cell), while the 25C pack charges to 26.1V (4.35V/cell). If you run both on the same hexa, set your charger profile correctly for each — a 26.1V charger will undercharge this pack, and a 27.3V charger will overcharge the 25C pack.

Simple rule: need to fly longer → this 32000mAh 10C pack. Need to push harder → the 23000mAh 25C pack.
