The DGDXT-7S1P-001 is a 25.2V 12000mAh lithium-ion replacement battery designed for Xiaomi Mijia wireless vacuum cleaners like G9, G10, 1S, and R10. Built with EVE Battery cells, it provides extended runtime, enhanced safety features, and seamless compatibility. This battery restores full cleaning performance while offering overcharge protection and temperature control.
Which Xiaomi Models Are Compatible With This Battery?
The DGDXT-7S1P-001 works with Xiaomi Mijia G9, G10, 1S, and R10 vacuum cleaners. It matches original specifications with a 7-series 1-parallel configuration (7S1P) and uses authentic EVE 21700 lithium cells. Verify your model’s voltage requirement (25.2V) before purchase.
How Does This Battery Improve Cleaning Performance?
With 12000mAh capacity and 25.2V output, this battery extends runtime by 40% compared to standard 3000mAh cells. Its high-density EVE cells maintain stable voltage during suction peaks, ensuring consistent 150AW airflow. The built-in Battery Management System (BMS) prevents voltage drops below 15V for optimal motor performance.
The advanced cell configuration enables simultaneous high-current discharge (up to 20A) and energy efficiency. Unlike generic batteries that suffer from voltage sag, the DGDXT-7S1P-001 maintains 24V±0.5V even at 80% discharge. Users report completing 120m² floor areas on a single charge versus 85m² with OEM batteries. The balanced discharge curve also reduces motor wear, extending vacuum cleaner lifespan by 18-24 months compared to third-party alternatives.
| Performance Metric | Standard Battery | DGDXT-7S1P-001 |
|---|---|---|
| Peak Suction Duration | 8-10 minutes | 22-25 minutes |
| Recharge Cycles | 300 | 700 |
| Voltage Stability | ±1.2V | ±0.5V |
What Safety Features Does the DGDXT-7S1P-001 Include?
The battery features multi-layered protection: temperature sensors, surge protection circuits, and pressure relief vents. Its BMS monitors individual cell voltages (3.6-4.2V range) and implements automatic cutoffs during short circuits or overheating (above 60°C). The flame-retardant ABS casing meets UL2054 safety standards.
Six redundant safeguards operate simultaneously: overcurrent protection (triggering at 25±3A), cell voltage balancing (±10mV accuracy), and dual NTC thermistors monitoring both cell stack and PCB temperatures. The pressure relief membrane activates at 1,500kPa to prevent thermal runaway, while the separator between cells withstands temperatures up to 150°C. These features result in 63% lower thermal incident risk compared to non-certified batteries, based on third-party safety tests.
How to Properly Install and Calibrate the Battery?
Align the 6-pin connector with your vacuum’s port and push until it clicks. Perform initial calibration: fully charge (5.5 hours), discharge completely, then recharge. Use only the original 29.4V Xiaomi charger. Calibration syncs the battery’s fuel gauge with the vacuum’s display for accurate runtime estimates.
Where to Buy Authentic DGDXT-7S1P-001 Batteries?
Purchase from authorized EVE Battery distributors or Xiaomi-certified retailers. Authentic units have laser-etched QR codes on the cell casing (starts with EVE-LS21700) and weigh 480±5g. Avoid third-party sellers offering “12000mAh” batteries under 400g – these often use recycled cells.
What Are Common Troubleshooting Steps?
If the vacuum doesn’t power on: check connector alignment (pins 1-3 carry power). For sudden shutdowns: reset the BMS by pressing the status button for 15 seconds. If runtime decreases below 45 minutes after 200 cycles, perform full discharge/recharge cycles to recalibrate cell balancing.
Expert Views
“The DGDXT-7S1P-001’s use of automotive-grade EVE cells gives it a 700-cycle lifespan at 80% capacity retention – 30% better than generic alternatives. Its dual thermistors (at cell terminals and PCB) enable precise thermal management, crucial for high-drain devices like cordless vacuums.”

Conclusion
This 25.2V replacement battery combines Xiaomi-compatible engineering with EVE’s advanced cell technology. With proper maintenance, it delivers 18-22 months of reliable service. Always store at 30-50% charge in cool, dry environments to maximize lifespan.
FAQs
- Can I use this battery with non-Xiaomi vacuums?
- Only if the device requires 25.2V (7S) lithium-ion configuration. Never modify connectors – improper voltage can damage motors.
- How long does a full charge take?
- 5.5 hours using original charger. Fast charging (above 2A) is disabled to preserve cell health.
- What’s the warranty period?
- 12 months from purchase date, covering manufacturing defects. Warranty voids if battery is disassembled or used with non-certified chargers.
