Core Technology Advantages
Extreme Power & Efficiency
Maximum 4000W power and 40A current significantly reduce charging time for high-capacity batteries, improving operational efficiency.
Comprehensive Safety Protection
Built-in multiple protection circuits including over-current, over-voltage, short circuit, over-temperature, and reverse polarity, ensuring safety during charging and for the equipment at the hardware level.
Robust Cooling & Durable Design
The cooling fan ensures stable heat dissipation during high-power operation. Sturdy housing and handle design facilitate on-site movement and usage.
Wide Compatibility & Applicability
Supports 6-14S (approx. 22.2V-58.8V) various lithium batteries (LiPo/LiHV) and smart batteries, applicable for voltages up to 4.50V/cell, meeting the needs of diverse professional equipment.
Usage Recommendations
- Essential Pre-charge Check: Always confirm the battery type (LiPo/LiHV), cell count (S number), and interface compatibility. Incorrect settings may cause battery damage or danger.
- Make Good Use of Storage Mode: After operation, if the battery will not be used for a short period, be sure to process it using "Storage Mode." This is the most effective method for maintaining lithium batteries and preventing performance degradation.
- Ensure Ventilation Space: During charging, do not cover the charger's cooling fan, ensure ample ventilation space around it to prevent the activation of overheat protection.

Frequently Asked Questions (FAQ)
Q1: What is the maximum capacity battery this charger can charge?
A: Theoretically, as long as the battery voltage is within the 6-14S range, there is no upper limit on capacity. Charging time is determined by the current you set. For example, to charge a 50000mAh (50Ah) battery pack, if set to 40A current, the theoretical full charge time is about 1.25 hours (not considering efficiency loss).
Q2: Can it be used on a standard 220V home outlet? What is the maximum power achievable?
A: Yes. At 220V voltage, a single channel of this charger can reach a maximum of 2000W, and both channels can work simultaneously at a maximum of 4000W (2000W per channel). When using, ensure the outlet, power strip, and circuit can handle the corresponding power (4000W is approximately 18A current). It is recommended to use a dedicated 16A or higher outlet or industrial power strip, and use an independent circuit to ensure safety.
Q3: The charger fan is noisy/noticeably hot. Is this normal?
A: During high-power operation, the dual fans work at full capacity to ensure heat dissipation, which will produce some wind noise, and the body will feel warm. This is normal. Please ensure good ventilation. If the fan makes abnormal noises or the body overheats causing protective shutdown, stop using it and check if ventilation is obstructed.
