The GOXX 8.0Ah Replacement Battery is designed specifically for the Aiper Scuba S1 cordless robotic pool cleaner. It offers a high 8000mAh capacity, which can significantly extend the cleaning time compared to the standard battery. This makes it an excellent choice for owners with larger pools or those who prefer fewer recharge cycles.
One of the standout features is the comprehensive safety system. The battery includes built-in protection against overcharge, overdischarge, overvoltage, overcurrent, and overheating. These safeguards help ensure safe operation and prolong the battery's lifespan, giving you peace of mind while your cleaner works.
Installation is straightforward and user-friendly. The battery is designed as a direct replacement, requiring only a screwdriver to swap out the old unit. There is no complicated wiring or technical expertise needed, so you can have your pool cleaner back in action within minutes.
In terms of build quality, the GOXX battery feels solid and well-constructed. It is RoHS certified, which indicates compliance with environmental and safety standards. However, since there are no user reviews yet, long-term reliability is unproven. Additionally, the higher capacity may add a slight weight increase, though this is unlikely to affect the cleaner's performance.
Overall, the GOXX 8.0Ah Replacement Battery is a compelling upgrade for Aiper Scuba S1 owners. It offers enhanced runtime, robust safety features, and easy installation at a competitive price. If you need more cleaning power and don't mind a third-party part, this battery is a smart investment.
Pros
- High 4000mAh capacity matches or exceeds original battery runtime.
- Easy installation with just a screwdriver, no technical skills required.
- Multiple safety protections built in for reliable, safe charging and use.
- Direct compatibility with Aiper Seagull SE, no modifications needed.
- Low self-discharge keeps the battery ready even after periods of non-use.
Cons
- Only compatible with the Aiper Seagull SE model, not other pool cleaners.

The YCFSERMYO 4000mAh replacement battery is a dedicated power solution for the Aiper Seagull SE cordless pool vacuum. It is designed for homeowners who want to revive their pool cleaner's original performance without buying a new unit. This battery is a direct drop-in replacement, making it a convenient and cost-effective option.
Standout features include a high 4000mAh capacity that allows the Seagull SE to clean larger pool areas in a single charge, reducing downtime. The battery uses high-density lithium cells that provide a steady 10.8V output, avoiding the power drops that can leave debris behind. In real-world use, this translates to consistent suction and thorough cleaning from start to finish.
The build quality is solid, with a blue casing that matches the original battery's dimensions and connector. Installation is truly plug-and-play: remove the old battery, slide in the new one, and tighten a couple of screws. No cutting, soldering, or adapters are needed. The battery also includes multiple safety protections (overcharge, over-discharge, etc.) for added peace of mind.
One potential drawback is that this battery is strictly compatible with the Aiper Seagull SE only, so it won't work with other models or brands. Additionally, there are no customer reviews yet, which means long-term durability is not confirmed. However, the specifications and certifications suggest a well-made product.
Overall, if you own an Aiper Seagull SE and need a replacement battery that restores full cleaning time and is easy to install, the YCFSERMYO 4000mAh is a strong choice. It offers a good balance of capacity, safety, and value for the price.
Buying Guide: What to Look for in a Robotic Pool Cleaner Replacement Battery
1. Voltage and Capacity Compatibility
Every robotic pool cleaner is designed to operate at a specific voltage and capacity range. Using a battery with the wrong voltage can damage the internal electronics or cause the cleaner to perform poorly. Always check the original battery label for voltage (e.g., 10.8V, 14.4V, or 21.9V). Capacity, measured in mAh, directly affects runtime. Higher capacities, like the 8000mAh options from GOXX and YCFSERMYO, allow longer cleaning sessions without recharging. Stick to the exact voltage required by your model—deviations can lead to overheating or a short lifespan.
2. Build Quality and Safety Certifications
A reliable replacement battery should have built-in protection circuits against overcharge, overdischarge, overvoltage, overcurrent, and overheating. Look for RoHS certification or similar standards. Brands like GOXX, KEEPBATT, and Cameron Sino specifically highlight these safety features. High-density lithium cells also reduce self-discharge and prolong cycle life. Avoid generic no‑name batteries that lack clear safety ratings—they can pose a fire hazard or fail prematurely. Verified protection circuits give you peace of mind when the battery is installed near water.
3. Ease of Installation and Form Factor
Most robotic pool cleaner batteries are designed to be plug‑and‑play, but some require a screwdriver. Before buying, confirm that the replacement battery matches the original dimensions, connector type, and mounting bracket. Products like the GOXX 8000mAh and YCFSERMYO 4000mAh emphasize minimal tool requirements. A perfect 1:1 fit avoids the need for trimming or adapter wires. If you are not handy with tools, choose a battery that offers hassle‑free installation. Always consult the product description or installation videos—many brands provide online guides.

Frequently Asked Questions
How do I know which replacement battery fits my robotic pool cleaner?
Check the original battery voltage, capacity, and part number printed on the battery label. Then compare with the product description. Most third‑party batteries list compatible models explicitly (e.g., Aiper Scuba S1, Aiper SE, Seauto Shark). If unsure, measure the dimensions and connector type. Many sellers provide fitment charts—use them or contact customer support.
Can I use a higher capacity battery for longer run time?
Yes, as long as the voltage is identical. A higher mAh capacity (like 8000mAh vs. 2600mAh) will run longer on a single charge. However, make sure the battery physically fits inside the compartment. Some cleaners have limited space. Also, a larger capacity may increase charging time. Always verify that the connector is the same.
Are replacement batteries safe to use near water?
Reputable replacement batteries are built with waterproof or water‑resistant housings and have protection circuits that prevent short circuits and overcurrent. However, the battery itself is not designed to be submerged; it sits inside a sealed compartment. Ensure the compartment gasket is intact and properly closed after installation. For more details on pool cleaner parts, visit our Replacement Parts category.
How long does a third‑party replacement battery last?
With proper care, a quality lithium‑ion replacement battery can last 1 to 3 years depending on usage cycles and storage conditions. High‑capacity cells like those in the FYIOGXG (10400mAh) or GOXX (8000mAh) often have hundreds of charge cycles. Avoid deep discharging and store the battery in a cool, dry place when not in use to maximize lifespan.
