Core Overview
The UP-3000 24S is a high-power intelligent charger designed for professional applications, specifically for 16-24S (series cell count) high-voltage lithium battery packs. Its core value lies in efficiency, safety, and intelligence. It can quickly charge batteries for large-capacity agricultural drones, film and television aerial photography, fire rescue, surveying and mapping, and other equipment with a high power of up to 3000W and a current of 35A. The product supports multiple lithium battery standards (LiPo/LiHV/Smart Batteries), features dual-channel charging capability, and comprehensive safety protection, aiming to provide professional users with a reliable and worry-free charging solution.
Core Technology Advantages
Ultra-High Power, Extremely Fast Charging
Maximum 3000W charging power and 35A current can quickly charge large capacity batteries such as 16-24S 20000mAh, 50000mAh, etc., greatly improving operational efficiency.
Dual-Channel Intelligent Charging System
Can charge two sets of 16-24S batteries simultaneously. One channel supports charging with balance port, and the other is standard charging, flexibly meeting different needs.
High-Precision Intelligent Management and Maintenance
Intelligent Balanced Charging: High-precision balancing of each cell voltage during charging ensures full charge without overcharging or undercharging, extending battery life.
Professional Storage Mode: Automatically charges or discharges the battery to a safe storage voltage (approx. 3.8V/cell), which is the scientific maintenance method for long-term storage.
Comprehensive Safety Protection
Built-in multiple protection circuits including over-current, over-voltage, short-circuit, overheating, and reverse connection, ensuring the safety of the charging process and equipment, allowing users to use with peace of mind.
Minimalist Operation, Transparent Information
One-Button Start: After selecting the battery type and current level, one button starts charging. Simple operation.
2.4-inch HD Color Screen: Clearly displays all key data of the dual-channel batteries in real-time, including voltage, current, power, capacity, time, etc. The interface intelligently changes color according to the charging status.
Wide Compatibility and Durable Design
Supports LiPo (4.20V)/LiHV (4.35V/4.40V/4.45V) and smart batteries, with wide compatibility.
Uses globally universal AC 100-240V wide voltage input, adapting to different regional power grids.
Usage Recommendations
Make Good Use of Storage Mode:
For batteries that will not be used for a long time (more than 3 days), be sure to use the "Storage Mode" for maintenance. This is the most important measure to protect battery performance, prevent swelling, and ensure safe storage.
Reasonable Current Selection:
Choose an appropriate charging current based on the battery's承受能力 (usually 0.5C-1C of the capacity value). For example, a 20000mAh battery can choose 10A-20A current. It is not recommended to always use the maximum 35A current for charging.
Ensure Heat Dissipation and Ventilation:
The charger generates heat during operation. Be sure to place it in a well-ventilated environment and avoid covering the cooling fan to ensure optimal performance and lifespan.
Prioritize Balanced Charging:
For batteries with balance leads, be sure to connect the balance lead and use the corresponding balanced charging channel to achieve the best battery balancing effect and ensure battery pack consistency.

Frequently Asked Questions (FAQ)
Q1: What is the maximum number of cells this charger supports?
A1: Maximum support 24S, that is, a battery pack with 24 lithium cells in series.
Q2: How long does it take to charge a 6S 22000mAh battery?
A2: This charger supports charging 16S-24S batteries. 6S is not supported.
Q3: What is the purpose of the 200W discharge power?
A3: The 200W discharge power is mainly used for the "Storage Mode". When the battery voltage is higher than the safe storage voltage, the charger can actively discharge to the storage voltage with higher power, which is faster and more accurate than natural discharge, and is beneficial for quick battery maintenance.
