Pros
- Large 8.0Ah capacity for extended runtime
- Multiple safety protections built in

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.

- 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.

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 Replacement Battery
Capacity and Voltage Match
The battery must match your pool cleaner’s original voltage and connector type. An incorrect voltage can damage the robot. Capacity (mAh) determines runtime; higher capacity provides longer cleaning cycles, such as the 8000mAh options from GOXX and YCFSERMYO for the Aiper Scuba S1.
Check your current battery’s voltage rating and connector design. Many replacement batteries, like the KEEPBATT 10.8V 2600mAh, fit specific models with unique connectors such as VH396-3P. For other replacement parts, explore our Replacement Parts category.
Safety Certifications
Look for batteries that include built-in safety protections: overcharge, overdischarge, overvoltage, overcurrent, and overheating. These features prevent hazards and extend battery life. All reviewed products comply with RoHS certification and standards.
Safety is crucial for lithium-ion batteries used in wet environments. The FYIOGXG battery for Seauto Shark uses a fully decoded chip for secure operation, just like the original.
Installation Simplicity
Most replacement batteries offer plug-and-play installation with no soldering. You typically need only a screwdriver. Options like the LMYDZER 6.0Ah for the WYBOT C1 feature a perfect 1:1 fit and drop-in replacement.
Easy installation saves time and avoids service fees. The YCFSERMYO 4000mAh for Aiper Seagull SE matches original size and mounting, making the swap straightforward. For guides on specific models, refer to our ACCESSORIES page.
Brand Reputation and Support
Reputable brands like KEEPBATT and Cameron Sino offer reliable support and quality assurance. They provide warranties or responsive customer service. Cameron Sino includes a 30-day refund and 24-hour response policy, which adds peace of mind.
Choosing a recognized brand reduces the risk of poor performance or compatibility issues. The FYIOGXG battery is ISO9001 certified, highlighting its quality manufacturing.
Final Thoughts
Choosing the right robotic pool cleaner battery replacement ensures long cleaning cycles and consistent performance. For Aiper Scuba S1 owners seeking maximum runtime, the GOXX 8.0Ah Replacement Battery for Aiper Scuba S1 delivers premium capacity and safety certifications. For budget-minded Aiper SE users, the KEEPBATT 10.8V 2600mAh High-Performance offers reliable power at an affordable price with easy installation. Both options restore your robot’s cleaning efficiency without requiring a full cleaner replacement.
