Which Robot Vacuum Models Support the SU SU Battery?
This battery is engineered for Xiaomi Lydsto R1, Roidmi Eve Plus, Viomi S9, and Eve Plus models. It also works with clones like Roborock S5/S6 due to shared voltage (14.4V) and connector designs. Always verify your vacuum’s model number against SU SU’s compatibility list to avoid mismatched dimensions or firmware conflicts.
| Model | Voltage Compatibility | Battery Dimensions |
|---|---|---|
| Xiaomi Lydsto R1 | 14.4V | 120x70x25mm |
| Roidmi Eve Plus | 14.4V | 120x70x25mm |
| Viomi S9 | 14.4V | 120x70x25mm |
Recent firmware updates (Q2 2024) have expanded compatibility to newer Viomi V3 Pro models through adaptive voltage regulation. Users should note that third-party vacuum variants may require manual firmware patching via manufacturer apps. SU SU provides monthly compatibility updates through its website, with automatic detection tools for verifying fitment. The battery’s modular design allows for minor dimensional adjustments using included spacer kits for older Xiaomi Mijia series units.
What Safety Features Does the SU SU Replacement Battery Offer?
Built with multi-layered safeguards: short-circuit prevention, temperature control chips, and voltage stabilizers. The battery management system (BMS) automatically cuts power during extreme temperatures (>45°C) or abnormal current surges. UL-certified cells and flame-retardant casing meet international safety standards, reducing fire risks during charging or extended use.
How to Install the SU SU Battery in Your Robot Vacuum?
- Power off the vacuum and flip it upside down
- Remove screws from the battery compartment (Phillips #1)
- Disconnect the old battery’s 4-pin connector
- Insert SU SU battery, aligning grooves with vacuum’s chassis
- Secure with screws and calibrate via vacuum’s settings menu
Allow a full charge cycle before first use for optimal calibration.
Why Choose SU SU Over OEM Xiaomi Robot Vacuum Batteries?
SU SU batteries provide 20% higher capacity (12800mAh vs. 10,400mAh OEM) at 40% lower cost. Independent testing shows 15% faster charging via QC3.0 compatibility. Unlike Xiaomi’s 6-month warranty, SU SU offers 18-month coverage with free replacement for capacity drops below 80% within 500 cycles. Includes a pry tool and T6 screwdriver for DIY installation.
Can the SU SU Battery Improve Cleaning Coverage Per Charge?
Yes. In lab tests, vacuums using SU SU batteries cleaned 1,800 sq.ft. on a single charge vs. 1,300 sq.ft. with OEM packs. The stable 14.4V output maintains suction power consistency, while adaptive discharge curves prevent voltage sag during high-load mopping cycles. Result: fewer interruptions for recharging in large homes.
What Maintenance Extends the SU SU Battery’s Lifespan?
- Avoid full discharges – recharge at 20% remaining
- Store at 40-60% charge if unused for >1 month
- Clean battery contacts quarterly with isopropyl alcohol
- Keep firmware updated via Xiaomi/Roidmi apps
These practices can extend cycle count to 1,200+ before capacity drops to 70%.
| Maintenance Practice | Impact on Lifespan |
|---|---|
| Partial charging (20-80%) | +300 cycles |
| Contact cleaning | Prevents 15% capacity loss |
| Firmware updates | Optimizes discharge patterns |
Lithium-ion batteries degrade faster in environments above 30°C – store units in climate-controlled areas during summer. SU SU’s smart charging algorithm reduces heat generation by 22% compared to standard charging protocols. For long-term storage, use the manufacturer’s preservation mode in the companion app, which performs maintenance charges every 45 days.
Expert Views
“The SU SU battery’s use of automotive-grade LG MJ1 cells explains its durability. Most third-party packs use recycled cells, but SU SU’s 2,500mAh per cell density matches Tesla’s Powerwall architecture. For heavy users, this is a game-changer.”
– Dr. Lin Chen, Robotics Power Systems Engineer
