Ultra Power UP2800-14S 6-14S Lithium Battery Charger
Ultra Power UP2800-14S 6-14S Lithium Battery Charger
Core Overview
The UP2800-14S is a high-power, dual-channel intelligent charger designed for professional and industrial applications. It adopts a dual independent power supply design, capable of simultaneously and independently charging two sets of 6 to 14 cell (6S-14S) lithium batteries (LiPo/LiHV/smart batteries) quickly, with a single channel maximum power of 1400W and a whole unit maximum power up to 2800W. Its core goal is to address the rapid charging and intelligent maintenance needs of high-capacity, multi-cell battery packs. It is widely used in fields with stringent requirements for power supply efficiency and reliability, such as drone aerial photography, fire rescue, agricultural plant protection, and surveying.
Core Technology Advantages
True Dual-Channel Independent System
Internally uses two completely independent 1400W power modules. Both channels can operate simultaneously at peak performance without interference, doubling efficiency.
Extreme Charging Speed
Single channel maximum charging current of 28A, enabling rapid charging of high-capacity battery packs like 16000mAh, 22000mAh, significantly reducing operation preparation time.
Wide Compatibility & Intelligent Operation
Fully supports LiPo (4.20V/cell), LiHV (4.35V/4.45V/cell), and smart batteries. Features parameter memory function, allowing "one-button start" for identical batteries, making operation simple. The 5-second intelligent switching color Chinese interface provides intuitive and comprehensive information display.
Professional Safety & Cooling Design
Equipped with multiple protections including over-voltage, over-current, reverse polarity, and over-temperature. Dual ball bearing cooling fans ensure stable operation under high-power output.
Usage Recommendations
- Always ensure the charger settings (LiPo/LiHV) exactly match the battery type. Incorrect settings may cause battery damage or danger.
- Ensure good ventilation during charging; do not cover the ventilation holes.
- For batteries not used for extended periods, it is recommended to use "Storage Mode" to maintain the voltage at a safe storage level.

Frequently Asked Questions (FAQ)
Q1: Can the two channels charge batteries of different brands and capacities?
A: Yes. The two channels are completely independent. They can simultaneously charge two sets of batteries with different brands, capacities, cell counts (must be within 6-14S range), and even different types (e.g., one channel charging LiPo, the other charging LiHV), with independent parameter settings.
Q2: What is the maximum capacity battery it can charge?
A: In terms of charging capability, as long as the battery voltage is within the 6-14S range, this unit does not have an absolute capacity limit. The actual charging speed depends on the current you set. For example, charging a 28000mAh (28Ah) battery at 28A current theoretically takes about 1 hour (1C charging).
Q3: Can it charge transmitter batteries?
A: Yes. The product supports charging/discharging for 2-3 cell (2S-3S) transmitter batteries.
Q4: Does it get very hot during charging?
A: During high-power operation (e.g., both channels at 28A), the charger will generate heat. The unit is equipped with two high-performance cooling fans for active heat dissipation, which is normal. Be sure to use it in a well-ventilated environment and do not block the air vents.
