EV-PEAK UD2 is an industrial‑grade smart charger designed for agricultural spraying drones, RC models, FPV, robotics, automotive, helicopters, and large aircraft. It integrates dual intelligent electromagnetic channels, supports active balancing and 14~20S battery packs (compatible with 18S), delivers a maximum output of 3000W and charging current up to 50A – fully charging in just 15 minutes. It features both charge and storage modes, built‑in voice broadcast that announces current, voltage, and battery type, plus Bluetooth remote control for remote monitoring via mobile app. The wireless charging (place‑and‑charge) eliminates cable clutter, and the charging port dust‑proof cap provides splash‑ and dust‑protection to extend service life. The intuitive display shows remaining time, battery level graph, temperature, voltage, and battery type, while the multiple protection system (reverse‑polarity, short‑circuit, etc.) ensures safe and reliable operation.
Dual‑channel independent charging 50A / 3000W ultra‑fast charging Supports 14‑20S LiPo / LiHV / Smart batteries Multiple protections: over‑charge, reverse‑polarity, short‑circuit Bluetooth remote + voice broadcast Wireless charging + active balancing
Note: Before use, confirm battery type is LiPo / LiHV / Smart, and cell count is 14‑20S. Ensure input voltage is within 100‑240V AC and use a grounded outlet.
Q1: Can this charger charge two batteries with different voltages or capacities at the same time?
Yes. The dual channels operate independently. The active balancing function automatically adjusts, so even if the batteries differ significantly in capacity or voltage, charging can be completed safely and efficiently without interference.
Q2: Will the fast charge (15 minutes) shorten battery life?
Not at all. The charger incorporates multiple protections (reverse‑polarity, short‑circuit, over‑temperature) and high‑precision balancing (±20mV), combined with smart battery management algorithms. It effectively prevents over‑charging and voltage imbalance, extending battery cycle life. Commercial operators can confidently use it in demanding scenarios.
Q3: What are the practical benefits of voice broadcast and Bluetooth remote control in field operations?
In noisy outdoor environments or when the pilot is away from the charger, voice broadcast announces current, voltage, and battery type without requiring screen monitoring. Bluetooth remote control via smartphone allows start/stop and parameter adjustments from a distance – ideal for multi‑drone operations where multiple chargers are managed simultaneously, boosting efficiency.
Q4: How do the dust‑proof cap and wireless charging benefit agricultural spraying drone users?
After field operations, charging ports often collect dirt or chemical residues. The dust‑proof cap effectively prevents short‑circuits and corrosion. Wireless charging (place‑and‑charge) allows recharging during short breaks without plugging/unplugging cables, reducing connector wear and failure rates.
Q5: How can dealers verify compatibility with existing drone batteries (e.g., 18S smart batteries)?
The unit supports 14~20S LiPo/LiHV/Smart batteries and provides automatic identification. Simply connect the battery and check the displayed data (capacity, temperature, voltage) – once confirmed, it can be deployed in bulk. Compatibility has been verified.
Q6: Is the charger stable in high‑temperature or humid environments?
It features an industrial‑grade thermal design (large size and weight). Active balancing and multiple protection mechanisms automatically reduce current or shut down if temperature exceeds limits. The dust‑proof/splash‑proof plugs enhance protection, making it suitable for outdoor agricultural settings – though prolonged direct sunlight or submersion should be avoided.
