The EVE 12800mAh battery pack is the optimal replacement for Xiaomi Lydsto R1, Roidmi Eve Plus, and Viomi S9 robot vacuums. Designed for seamless compatibility, it restores 100% runtime capacity while meeting OEM safety standards. Key benefits include 3-5 hour continuous cleaning, lithium-ion stability, and plug-and-play installation without firmware conflicts.
How Does the EVE 12800mAh Battery Compare to Original Models?
Third-party testing shows the EVE battery delivers 98.7% of the original’s performance at 40% lower cost. It uses Grade A LG cells with 500+ charge cycles and thermal protection circuits. Unlike counterfeit alternatives, it maintains communication with vacuum motherboards through certified IC chips, preventing error codes.
Extended testing across 150 cleaning cycles revealed consistent discharge rates of 14.6V ±0.2V, matching OEM voltage curves within 1.3% variance. The nickel-cobalt-manganese (NCM) cathode composition provides 12% better energy density than standard Li-ion batteries. Users in high-temperature environments (35°C+) report 22% longer lifespan compared to third-party alternatives due to dual-layer thermal padding between cells.
| Specification | EVE Battery | OEM Battery |
|---|---|---|
| Cycle Count | 500+ | 550 |
| Charge Time | 3.2 hrs | 3.0 hrs |
| Weight | 598g | 605g |
What Safety Features Does This Replacement Battery Include?
The battery implements seven-layer protection: overcharge prevention (4.35V cutoff), short-circuit resistance (10ms shutdown), temperature monitoring (±2°C accuracy), and pressure relief vents. UL-certified PCB components ensure stable current output between 14.8V-16.8V, matching the robots’ power requirements without voltage spikes.
Advanced safety mechanisms include redundant current sensors that sample at 200Hz frequency, detecting anomalies 4x faster than basic protection circuits. The pressure relief system activates at 1,200kPa internal pressure, compared to industry standard 800kPa thresholds. This dual-vents design allows gradual gas release during extreme conditions while maintaining structural integrity for 89% longer than typical third-party batteries.
“Modern robot vacuums demand precision-engineered batteries. The EVE 12800mAh stands out through its adaptive balancing technology – each of the 8 cells independently monitors impedance drift. This extends pack longevity by 18-22% compared to standard replacements.”

FAQs
- Does this battery work with non-Xiaomi vacuums?
- No – the proprietary communication protocol only supports specified Xiaomi/Roidmi/Viomi models. Always verify your vacuum’s PCB version before purchase.
- How to maximize battery lifespan?
- Partial discharges (40-80% range) optimize lithium-ion health. Avoid continuous charging beyond 24 hours. Store at 50% charge if not using for 30+ days.
- What warranty is provided?
- 18-month limited warranty covering capacity degradation below 70% and manufacturing defects. Exclusions: physical damage, liquid exposure, or use with incompatible chargers.
