Core Overview
The ULTRA POWER UP8 is a flagship charging workstation designed for RC hobbyists, automotive model enthusiasts, and industrial users who pursue efficiency and professionalism. It surpasses the traditional single charging function by integrating three core capabilities: dual independent high-power charging/discharging, battery testing/maintenance, and equipment inspection. With a total power of dual channels AC 400W/DC 600W, independent operation logic, and features like 10W wireless phone charging, it becomes a versatile battery management solution that combines efficiency, safety, and convenience.
Core Technology Advantages
Truly Independent Dual Channels, Efficiency Multiplied
Core Value: The two channels are completely independent in hardware and control systems, allowing simultaneous execution of different tasks (charging, discharging, storage) on two battery groups with different types, states, and specifications, without interference. This means you can charge one battery while performing storage maintenance on another, halving waiting time.
Multi-Functional, Integrated Professional Maintenance & Inspection Platform
Core Value: Built-in servo tester and motor/ESC tester allow quick on-site inspection of servo response angles and motor operation without additional equipment. It is not just a charger but also your portable repair and diagnostic tool, saving equipment costs and troubleshooting time.
200W High-Power Active Balance Discharge, Solving Storage Pain Points
Core Value: By connecting the dedicated UP-D200 discharger, the discharge power per channel can be increased to 200W, with simultaneous cell balancing during the process. For high-capacity batteries (e.g., 6S 12000mAh), it can quickly and safely reduce the voltage to storage voltage (e.g., 3.85V/cell), eliminating the long hours of waiting associated with low-power discharge, greatly improving battery maintenance efficiency and safety.
Convenient 10W Wireless Phone Charging
Core Value: Independent wireless charging module, compatible with mainstream phone models. During busy work intervals, simply place your phone on it to charge, without consuming the power resources of the battery channels, keeping your communication and debugging devices powered at all times.
Usage Recommendations
- Power Supply Configuration is Key to Performance: To fully utilize the UP8's total power of 600W in DC mode (300W per channel), it is highly recommended to use an industrial switching power supply with a rated output above 30V/25A or a high-capacity LiPo battery pack. Using an insufficient power source will limit the charger's performance and may cause overload damage to the power supply.
- Make Good Use of "Storage" Mode for Battery Maintenance: After each use, always use the "Storage" function to automatically charge/discharge the lithium battery (LiPo/LiHV) to the recommended storage voltage of about 3.85V/cell. This is the most important step to extend battery cycle life and prevent swelling.

Frequently Asked Questions (FAQ)
Q1: Can both channels of the UP8 work at maximum power (300W+300W) simultaneously?
A1: Yes, but only if your DC input power supply is capable of providing continuous power exceeding 600W (e.g., 30V/20A or above). When using an AC power adapter, the maximum total power for both channels is 400W (200W+200W).
Q2: When using wireless phone charging, will it affect the charging speed of the batteries?
A2: It will basically not affect. The wireless charging module is independently designed with a maximum power consumption of only 10W. The charger's power management system prioritizes the power requirements of the two battery channels. The wireless charging function is equivalent to an "additional" convenience feature.
Q3: How is the external discharge mode specifically used? What are its advantages over internal discharge?
A3: You need to purchase the dedicated UP-D200 discharger and connect it to the charger's "EXT.DISCH" port via a cable. Its core advantages are threefold:
- Extremely Fast: Discharge power up to 200W, far exceeding the internal discharge of 5-10W, improving efficiency by tens of times when handling high-capacity batteries.
- Safe Balancing: Performs balancing function even during high-speed discharge, ensuring all cells are at consistent voltage at the storage voltage.
- Professional Maintenance: Can quickly and accurately adjust the battery to the ideal long-term storage voltage, which is a necessary means for professional battery maintenance.
