Why Fishing Drones Require High Capacity Batteries
Fishing drones are designed to carry payloads such as bait release mechanisms, waterproof housings, and high-power motors. Compared to standard camera drones, they operate under heavier load and often travel several hundred meters offshore. For this reason, batteries below 5000mAh are rarely used in this category.
A typical fishing drone battery setup prioritizes flight time, voltage stability under load, and connector durability. XT60 and XT90 connectors are commonly used due to higher current demand.
4S Fishing Drone Batteries (Most Common Configuration)
The majority of fishing drones operate on 4S systems (14.8V standard LiPo or 15.2V LiHV). The most common capacity range is 6000–6500mAh, although 5000mAh to 8000mAh options are also seen depending on payload and flight distance requirements.
| Specification | Typical Range |
|---|---|
| Voltage | 4S (14.8V LiPo / 15.2V LiHV) |
| Capacity | 5000–8000mAh |
| Connector | XT60 / XT90 |
Common 4S fishing drone platforms include SplashDrone 3 / 3+ and Poseidon II Pro Black. Always verify battery compartment dimensions before purchase.
6S Fishing Drone Batteries (Heavy-Lift Platforms Only)
Certain high-lift fishing drones such as Cuta Copter Trident 5000 operate on 6S systems (22.2V). These batteries are not compatible with 4S drones and must only be used with 6S-rated electronic speed controllers and flight systems.
| Specification | Typical Range |
|---|---|
| Voltage | 6S (22.2V LiPo) |
| Capacity | 5000–6000mAh |
| Connector | XT90 |
If your drone is a 6S platform, do not install a 4S battery. Using incorrect voltage can damage your drone electronics.
Battery Size & Fitment Guidelines
Fishing drone battery compartments vary by model. Typical 4S 6500mAh batteries measure approximately 110–140mm in length, 60–70mm in width, and 35–45mm in thickness. Larger 8000mAh packs may approach the upper limit of these dimensions.
Before purchasing, confirm:
- Voltage requirement (4S or 6S)
- Maximum battery compartment dimensions
- Connector type (XT60 or XT90)
What Is Not Compatible
Smart slide-in battery systems (such as proprietary integrated battery packs) are not compatible with standard LiPo batteries. This collection includes only conventional RC LiPo batteries with external connectors.
Always verify your drone's voltage and battery structure before purchase.
Fishing Drone Battery FAQ
What battery does a fishing drone use?
Most fishing drones use 4S LiPo batteries above 5000mAh. Heavy-lift platforms may use 6S batteries.
Is 4S enough for a fishing drone?
Yes, 4S is the most common configuration in the market. However, always confirm your drone’s required voltage.
Can I use a higher mAh battery?
You may use higher capacity if it fits the battery compartment and matches the required voltage.
Are 4S and 6S batteries interchangeable?
No. 4S and 6S batteries are not interchangeable. Using incorrect voltage can damage your drone.
