In agricultural drone work, even a small improvement in battery endurance can change the pace of the entire day. Anyone who has spent time spraying fields knows how frustrating it gets when the drone needs to land again and again just to swap batteries. We built our 6S 25200mAh Li-ON Agro battery for one simple purpose — to stop that cycle of constant interruption.
And the question every operator asks us first is always the same:
“How many tanks can I finish on one charge?”
Our answer is short, solid, and tested on the field:
Three full tanks. One charge. No drama.
Why Hitting Three Tanks Matters So Much
Farm work moves fast. A good spraying window can be just a few hours long, and every minute you waste landing the drone, pulling out batteries, cooling them, recharging, and fixing connectors… it all adds up. The truth is, spraying isn’t hard — but managing batteries is.
That’s exactly where this battery changes the rhythm of your day.
With the 6S 25200mAh Li-ON Agro, we designed a pack that lets you complete three consecutive spray cycles (for standard 10–12L agricultural drones) without touching the charging station. That single improvement alone reduces ground time more than most people expect. After a few cycles, it’s almost surprising how much smoother the day feels when you’re not constantly preparing backups.
Built With the Field in Mind — Not a Lab Bench
A lot of batteries work fine on paper.
But ag-terrain is the real test — humidity, dust, long missions, sudden manoeuvres, uneven payload discharge, and heat.
So when we developed this battery, we didn’t focus on “big numbers”. We focused on endurance that actually translates into meaningful work.
Here’s what gives this battery the capacity to complete three tanks in one go:
- 25200 mAh capacity that genuinely holds under load
- 6S configuration (around 21.6V nominal) tuned for agro drones
- Excellent discharge stability, allowing the drone to lift spray payloads without voltage sag
- High-quality cylindrical cells designed for endurance rather than flashy specs
- Weight around 2.7 kg, balanced to suit 10–12L spray drones
- Solid build that avoids bulging, even after repeated long-duration cycles
These choices weren’t random. We tested dozens of configurations until we reached a combination that keeps delivering from the first tank to the third.
A Realistic Picture of “Three Tanks”
Let’s walk through how it works in real field conditions:
1. First Tank — Fresh Takeoff
You start the day by filling the spray tank, fastening the battery, and launching. The drone lifts smoothly and covers the entire field section without stressing the battery.
2. Quick Refill — The Battery Stays In
You bring the drone down, swap the spray solution, and launch again.
No battery swap. No time wasted.
3. Second Tank — Still Going Strong
The second mission completes without the usual drop in performance that cheaper batteries show halfway through heavy spraying.
4. Third Refill — The Last Push
You load the third tank, check the voltage, confirm everything is stable, and send the drone out again. The battery comfortably powers the entire third cycle.
5. Only Then You Swap
Most users tell us the same thing: completing three tanks in a row without touching the battery feels almost too convenient at first — then it becomes impossible to go back.
Why It Outperforms Typical Drone Batteries
Operators who switch to our 6S 25200mAh Li-ON Agro usually notice these two changes immediately:
1. Less Downtime, More Actual Work
Since you’re not juggling multiple batteries, the drone spends more time in the sky and less time waiting on the ground.
2. A Lot Fewer Batteries Needed
Instead of buying and maintaining four or five batteries just to keep up with demand, you might only need two or three. Over a year, the savings in both cost and hassle are huge.
3. No More Voltage Sag on Heavy Payloads
Many LiPo batteries drop voltage sharply the moment the drone carries a full spray load. This battery holds steady, giving consistent thrust and runtime from start to finish.
4. Longer Life Cycle Compared to LiPo
Li-ion chemistry generally lasts more cycles than LiPo, but the real benefit comes from how stable the performance remains even after dozens of heavy sessions. It's designed for agricultural stress — not hobby-grade flying.
How to Actually Get the Best Out of This Battery
To hit that “three-tank” performance consistently, a few practices go a long way:
- Use the right drone model that supports 6S Li-ion.
- Avoid overloading the spray tank beyond recommended limits.
- Store the battery properly when not in use — avoid extreme heat.
- Let the battery cool naturally after long flights before recharging.
- Inspect connectors regularly, especially in dusty regions.
These are small habits, but they make a big impact on overall battery health and performance.
Who Benefits the Most from This Battery?
Although anyone using a compatible drone will see the advantage immediately, certain users get the maximum value:
- Professional drone spraying service providers
- Farmers handling large acreage in single sessions
- Rental fleets needing reliable equipment
- Operators who travel long distances to fields
- Anyone wanting fewer batteries, fewer swaps, and fewer headaches
The consistency of this battery is what makes it stand out — it performs the same way day after day without sudden surprises.
The Bottom Line — Three Tanks, One Charge, Real Results
We designed the 6S 25200mAh Li-ON Agro with a very practical goal: keep the drone in the air longer, and keep work moving without interruptions.
Everything else — the capacity, the voltage, the weight, the cycle endurance — all feeds into this single promise.
If you’re tired of juggling too many batteries, or you’re looking for something that can handle heavy spraying without fading halfway, this battery is built exactly for that.
We’re proud of how reliably it hits the “three-tank per charge” benchmark, not just in ideal conditions but in real fields — the dusty, humid, unpredictable environments where drones actually work.
