The EVE INR18650 MH1-4S1P-SC is the OEM-approved lithium-ion battery designed specifically for the Xiaomi Mijia Robot Vacuum-Mop P. With a 4S1P configuration (4 cells in series), it delivers stable 14.8V voltage and 3200mAh capacity, ensuring extended runtime and compatibility. Its built-in protection circuit prevents overcharging, overheating, and short circuits, making it a safe, long-lasting replacement.
Differences Between Eve and Other Brands
How Does the EVE INR18650 MH1-4S1P-SC Compare to Third-Party Alternatives?
Third-party batteries often lack the precision engineering of OEM options like the EVE INR18650 MH1-4S1P-SC. Generic alternatives may use lower-grade cells, resulting in reduced capacity (e.g., 2800mAh vs. 3200mAh), unstable voltage output, and higher failure rates. Xiaomi’s firmware is optimized for the original battery’s discharge curve, ensuring accurate battery-level reporting and avoiding error codes common with knockoffs.
Independent lab tests reveal third-party batteries degrade 30% faster after 100 charge cycles compared to OEM cells. For example, a 2023 study by BatteryBench showed generic batteries dropped to 70% capacity within six months, while the EVE MH1-4S1P maintained 89% capacity under identical usage. Voltage sag is another critical factor—during peak suction (15W load), third-party packs averaged 13.2V versus the OEM’s consistent 14.4V, leading to incomplete cleaning cycles. Users also report 23% more “stuck robot” incidents with non-OEM batteries due to sudden power drops.

What Safety Features Does the EVE INR18650 MH1-4S1P-SC Offer?
This battery integrates multiple safety mechanisms: a PCM (Protection Circuit Module) with temperature sensors, overcurrent/overvoltage cutoffs, and cell balancing. The nickel-plated steel casing provides physical durability, while the Li-ion NMC (Nickel Manganese Cobalt) chemistry minimizes thermal runaway risks. Independent testing shows it meets UN38.3 and IEC62133 standards, critical for fire safety in robotic vacuums.
How to Properly Install the Replacement Battery in Your Xiaomi Robot Vacuum-Mop P?
- Power off the device and flip it upside down.
- Remove the seven Phillips-head screws securing the battery compartment.
- Disconnect the old battery’s JST connector gently using tweezers.
- Insert the EVE INR18650 MH1-4S1P-SC, ensuring the connector aligns with the port.
- Reassemble screws and calibrate via the Mi Home app (Settings > Battery > Reset).
Why Does Using a Non-OEM Battery Risk Damaging Your Robot Vacuum?
Non-OEM batteries often lack firmware synchronization, causing mismatches in voltage reporting. Xiaomi’s vacuum-mop relies on precise battery data for motor control and charging algorithms. Incompatible cells can trigger error 105 (battery communication failure) or overstress the cleaning motors, reducing their lifespan by up to 40%. Additionally, third-party batteries may void Xiaomi’s warranty.
Case studies from repair centers show that 68% of vacuum motors failing within 18 months had used third-party batteries. The root cause traces to unstable current delivery—OEM batteries provide a steady 4.5A during mopping, while generics fluctuate between 3.8-5.2A. These irregularities force the mainboard to constantly adjust power draw, accelerating wear on MOSFET transistors. Xiaomi’s diagnostic logs also reveal non-OEM users experience 3x more “Battery Communication Timeout” errors, requiring costly control board replacements.
How to Extend the Lifespan of Your EVE INR18650 MH1-4S1P-SC Battery?
Avoid deep discharges; recharge when the battery drops below 20%. Store the vacuum in a cool, dry place (15–25°C ideal). Use only the original 16.8V Xiaomi charger to prevent overvoltage. Perform full discharge cycles monthly to recalibrate the battery meter. EVE’s datasheet confirms 500+ cycles at 80% capacity retention with proper care.
Where to Buy Genuine EVE INR18650 MH1-4S1P-SC Batteries?
Purchase directly from Xiaomi-authorized retailers like Mi Store, Amazon’s Xiaomi flagship store, or certified partners like EVE Energy. Authentic batteries include a QR code on the label; scan via Mi Home app to verify. Avoid eBay or AliExpress listings priced below $45—counterfeits often omit safety circuits.
| Retailer Type | Price Range | Verification Method |
|---|---|---|
| Xiaomi Official Stores | $49.99-$54.99 | In-store validation |
| Authorized Online | $47.99-$52.99 | Scannable QR code |
| Unverified Sellers | $29.99-$39.99 | No authentication |
“The EVE INR18650’s 4S1P design isn’t just about capacity—it’s engineered to match the vacuum’s peak power demands during mopping. Third-party packs often bottleneck at 2C discharge rates, while Xiaomi’s OEM cells handle 5C bursts seamlessly. This difference impacts suction consistency on carpets and long-term device health.”

FAQs
- Can I use a higher-capacity battery than 3200mAh?
- No. Xiaomi’s firmware and charging system are calibrated for 3200mAh. Higher capacities may cause overheating or charging errors.
- How long does shipping a genuine battery take?
- Authorized sellers typically deliver within 3–7 days. Avoid “express” listings from unverified sources.
- Does replacing the battery reset device settings?
- No, but always recalibrate via the Mi Home app to ensure accurate battery percentage tracking.
