Core Overview
The UP4000-24S is a dual-channel high-power intelligent charger designed for professional and industrial applications. It is specifically designed for multi-cell lithium battery packs, featuring a high charging power of up to 4000W and a 25A current output. It can simultaneously perform fast, balanced charging and discharging operations on two groups of 16-24S batteries. The product integrates a high-definition color screen display, global wide voltage adaptation, multiple safety protections, and intelligent charge/discharge management. It is widely used in fields that require efficient and reliable battery management, such as drones, photographic equipment, fire rescue, surveying, and agricultural machinery.
Core Technology Advantages
Dual-Channel High-Efficiency Fast Charging
Maximum 4000W power, supports two independent 25A outputs, capable of simultaneously working on two groups of 16-24S batteries, multiplying efficiency.
Full Voltage Global Compatibility
AC 100-240V wide-range input, can be safely used worldwide without a voltage converter.
Multiple Safety Protections
Integrates over-voltage, reverse polarity, short circuit, and over-temperature protection, combined with high-quality components and a reinforced structure, ensuring the safety of the equipment and batteries.
Usage Recommendations
- Strictly match 16-24S (i.e., nominal voltage approx. 60V-100V) LiPo (Lithium Polymer), LiHV (High Voltage Lithium), or smart batteries. Before use, always confirm battery total voltage and interface compatibility.
- For regular use, it is recommended not to exceed the battery's rated charging rate.
- Maintenance is crucial: Before long-term storage of batteries, always use "Storage Mode". This is the most effective method to protect battery performance, prevent swelling, and capacity degradation.
- When connecting batteries, always confirm the polarity is correct.

Frequently Asked Questions (FAQ)
Q1: How many batteries can this charger charge at once?
A: As a dual-channel charger, it can simultaneously and independently charge (or discharge) two groups of 16-24S battery packs. The parameters for each battery group can be set separately.
Q2: My battery is 12S. Can I use it?
A: No. The minimum series cell count supported by this charger is 16S. Charging a 12S battery may cause the device to fail to recognize it or operate abnormally. Please choose a charger that supports the corresponding cell count.
Q3: The fan is very noisy/obviously hot during charger operation. Is this normal?
A: This is a normal phenomenon. At maximum power output, the fan operates at high speed to ensure heat dissipation, which is a manifestation of its thermal management system working. Please ensure the device is well-ventilated on all sides and do not block the ventilation holes.
Q4: Is an additional transformer needed for use abroad?
A: No. This unit supports AC 100-240V wide voltage input. In the vast majority of countries and regions around the world, it can be used directly by simply using the corresponding power plug adapter.
