Traditional chargers are black boxes — is it fully charged? Is something wrong? You have to walk over and check. Sanyi Technology's digital smart charger changes that with WiFi connectivity and app control, so you can monitor every charger from your desk.

Why Choose the Sanyi Smart Charger?
The problem with most chargers on the market:
- Premium brands like NOCO and CTEK offer great charging performance, but no WiFi or cloud monitoring — each device is an information silo
- Budget brands are cheap but lack smart features, offering no differentiation
- Victron Energy has cloud monitoring, but at a premium price point aimed at professionals
Sanyi's answer: Victron-level remote management at a mid-range price.
Key Features
Multi-Stage Intelligent Charging — One Charger for All Battery Types
| Battery Type | Charging Mode | Highlights |
|---|---|---|
| Lithium (Li-ion / LiFePO4) | CC-CV 2-stage | Constant current → constant voltage, precise cutoff control |
| Lead-acid (12V / 24V / 48V) | 4-stage independent | Each stage fully configurable for optimal battery care |
| Aging test | Constant power output | For battery capacity testing and QC |
- All charging parameters are fully configurable to match any battery specification
- Stage transitions are fully automatic — no manual intervention needed
- Auto-disconnect after full charge with trickle protection (lithium) or float maintenance (lead-acid)
WiFi + App Control — Remote Monitoring Made Simple
This is the Sanyi smart charger's biggest differentiator. Built-in WiFi connects the charger to the cloud, giving you full control from your smartphone.

Live Monitoring
- Charging status at a glance: Charging / Idle / Complete / Fault (color-coded)
- Voltage, current, power, and temperature refreshed every 4 seconds
- Battery percentage with animated ring display
- Dual temperature monitoring with automatic over-temperature alerts
Charge History
- Cumulative energy consumption (kWh) tracking — calculate your exact electricity costs
- Detailed session records: duration, peak parameters, energy consumed, completion status
- Full history for maintenance analysis and reporting
Remote Configuration
- Full parity with PC software — every setting accessible from your phone
- Battery type, charging curves, protection thresholds, temperature compensation — all remotely adjustable
- One-tap read / write / factory reset
- No site visits needed — dramatically reduce operational costs
Real-world scenario: You manage 50 chargers across a charging station. Previously, every unit required an on-site visit for monitoring and configuration. Now you see every device's status on your phone, adjust parameters remotely, and receive instant fault alerts. Operational labor reduced by 80%.
6-Layer Safety Protection — Complete Battery Safety
| Protection | Description | Recovery |
|---|---|---|
| Over-temp derating | Automatically reduces charging power when device temperature rises | Auto-recovers when cooled |
| Over-temp disconnect | Stops charging when temperature exceeds threshold | Auto-recovers when temperature normalizes |
| Critical thermal shutdown | Emergency shutdown at extreme temperatures | Power cycle required |
| Over-voltage protection | Disconnects if battery voltage exceeds safe limit | Non-recoverable, prevents overcharging |
| Over-current protection | Disconnects on abnormal current draw | Non-recoverable, prevents short circuit damage |
| Charge anomaly detection | Detects battery fault if voltage fails to rise over time | Non-recoverable, prevents wasted energy |
Every fault triggers an instant push notification to the app, so managers know immediately — before damage occurs.
Adaptive Temperature Compensation — Reliable Charging Year-Round
Lead-acid batteries require different charging voltages at different temperatures. The Sanyi smart charger has a built-in ambient temperature sensor for fully automatic compensation:
- Hot weather: Automatically lowers charging voltage to prevent overcharging and gassing
- Cold weather: Automatically raises charging voltage to ensure full charge
- Compensation parameters are configurable with auto-detect and manual modes
- Zero manual adjustment needed — works reliably in any climate
kWh Energy Metering — See Your Charging Costs
A feature most chargers on the market simply don't have.
- Precise energy consumption (kWh) recorded for every charge session
- Cumulative total energy statistics
- Directly calculate electricity costs — essential for commercial operations
- Enables per-kWh billing for shared charging services

FAQ
What battery types are supported?
Three modes: lithium (CC-CV 2-stage, compatible with Li-ion and LiFePO4), lead-acid (4-stage independent charging), and aging test mode. All voltage and current parameters are fully configurable, supporting 12V to 72V battery packs of various capacities.
Do I need additional hardware for app control?
No. The charger has a built-in WiFi module. Connect it to any WiFi network, scan the QR code on the device, and the app is ready to use — zero installation, zero additional cost.
Can I manage multiple chargers simultaneously?
Yes. The app supports adding multiple devices. Switch between chargers in a single interface — ideal for charging stations, factories, and fleet management scenarios.
Will it keep charging after the battery is full?
No. The charger automatically disconnects after detecting a full charge. Lithium batteries get a trickle protection phase, and lead-acid batteries get a float maintenance phase before final disconnect — preventing overcharge and extending battery life.
Will settings be lost after a power outage?
No. All charging parameters are automatically saved to non-volatile memory. Settings are restored on power-up without any reconfiguration.
Is this available for international markets?
Yes. The international version supports a standalone app (not limited to WeChat). WiFi cloud connectivity works globally. The product supports CE, FCC, and other international certifications for export markets.
