The Xiaomi Viomi S9, Lydsto R1, and Roidmi Eve Plus 14.4V lithium batteries use EVE’s advanced 2P4S configurations to deliver unmatched runtime (5,200–12,800mAh) and safety. These batteries optimize energy density and thermal stability, making them ideal for robotic vacuums. Their compatibility with multiple models and adaptive charging cycles ensure longevity and eco-friendly performance.
How Do EVE Lithium Batteries Enhance Cleaning Efficiency?
EVE’s 2P4S lithium batteries balance voltage stability (14.4V) and capacity, enabling robotic vacuums to clean larger areas without frequent recharging. For example, the 12,800mAh variant powers devices for up to 300 minutes, while adaptive discharge curves prevent voltage drops during high-load tasks like carpet cleaning. This ensures consistent suction power and reduces interruptions.
The batteries employ dynamic power allocation technology, which intelligently distributes energy based on surface type. When transitioning from hard floors to carpets, the system increases current delivery by 15-20% within milliseconds. This real-time adjustment prevents motor strain while maintaining optimal suction at 2,500Pa. Additionally, the low self-discharge rate (3% per month) ensures ready-to-use performance even after prolonged storage.

Which Devices Are Compatible with These Batteries?
These batteries are designed for Xiaomi Viomi S9, Lydsto R1, Roidmi Eve Plus, and similar 14.4V robotic vacuums. Key compatibility factors include:
- Connector type (JST-XH or Molex)
- Dimensions (e.g., 120mm x 70mm x 35mm)
- BMS communication protocols
| Model | Connector Type | Dimensions |
|---|---|---|
| Viomi S9 | JST-XH 4-pin | 122mm x 68mm x 34mm |
| Lydsto R1 | Molex 2.5mm | 118mm x 72mm x 36mm |
What Safety Features Are Integrated into These Batteries?
EVE batteries include multi-layered safeguards:
- Overcharge/over-discharge protection
- Short-circuit prevention
- Temperature sensors that halt charging at 45°C+
- Pressure relief valves to prevent swelling
These features meet UL 2054 and IEC 62133 certifications, ensuring compliance with global safety standards.
The battery management system (BMS) continuously monitors cell balancing, maintaining voltage differences below 0.05V across all cells. This precision prevents hot spots and extends cycle life. In thermal runaway scenarios, ceramic separators expand to create firewalls between cells, containing potential failures to individual units. Third-party testing shows these batteries withstand nail penetration tests at 25°C ambient temperature without ignition.
How Does Battery Capacity Affect Runtime?
Higher mAh ratings directly extend operational time. For instance:
- 5,200mAh: 120–150 minutes
- 9,800mAh: 220–260 minutes
- 12,800mAh: 280–300 minutes
Note: Actual runtime depends on suction mode and floor type. Turbo modes can reduce duration by 30%.
Why Choose Lithium-Ion Over Other Battery Types?
Lithium-ion batteries offer 40% higher energy density than NiMH alternatives, resulting in lighter weight and faster charging (0–100% in 3.5 hours). They also lack memory effect, allowing partial charging without capacity loss. EVE’s cells retain 80% capacity after 800 cycles, doubling the lifespan of traditional batteries.
How to Properly Maintain These Batteries?
Maximize battery life with these tips:
- Avoid full discharges—recharge at 20%+
- Store at 50% charge in cool, dry environments
- Clean terminals monthly with isopropyl alcohol
- Use only approved chargers (e.g., 16.8V/1.5A)
What Sustainability Practices Are Associated with EVE Batteries?
EVE employs closed-loop recycling, recovering 95% of lithium, cobalt, and nickel. Their factories use 60% renewable energy, reducing CO₂ emissions by 8.2 tons per 10,000 batteries produced. Users can return spent batteries via EVE’s take-back program for eco-friendly disposal or refurbishment.
What Future Innovations Are Expected in Robotic Vacuum Batteries?
Emerging trends include:
- Solid-state designs (2026–2027) for 30% higher capacity
- AI-driven BMS for predictive health monitoring
- Wireless charging compatibility
How to Install a Replacement Battery Correctly?
Follow these steps:
- Power off the device and remove the old pack
- Align connectors—do not force
- Secure with screws (torque: 0.6–0.8 Nm)
- Calibrate by charging to 100% before first use

FAQs
- Can I Use a 9,800mAh Battery in a Xiaomi Viomi S9?
- Yes, if the physical dimensions and connector type match. Confirm compatibility using the model number (e.g., EVE-14.4V-9800).
- How Long Does a Full Charge Take?
- Approximately 3.5–4 hours for a 12,800mAh battery using a 1.5A charger. Fast chargers (2.5A) reduce this to 2.5 hours but may shorten cycle life.
- Are These Batteries Covered by Warranty?
- EVE provides an 18-month warranty, covering defects and premature capacity loss (below 70% within 500 cycles). Damage from misuse is excluded.
