UPS4AC Four-Channel Intelligent Charger

Core Overview

The UPS4AC is a four-channel intelligent charger designed for model hobbyists and professional users. Its core value lies in "one device, multiple functions, worry-free and efficient": it can be directly plugged into household AC power without an external power adapter, and can simultaneously charge four groups of batteries of different types and specifications independently. It perfectly solves the charging management problem for users who have various small lithium batteries (LiPo/LiHV) and nickel-metal hydride/nickel-cadmium batteries (NiMH/NiCd) at the same time, making it an ideal choice for a desktop charging station.

Core Technology Advantages

🔌

Worldwide AC Power Compatibility

Supports 100-240V wide voltage AC power, globally compatible, eliminating the need to purchase bulky external adapters, saving cost and space.

Four Independent Channels

Four channels can be set independently, allowing simultaneous mixed charging, greatly improving work efficiency for multi-battery users.

🔄

Extremely Wide Interface Compatibility

Comes standard with multiple mainstream balance connectors and interfaces such as SM, XH, MICRO, MX, JST, mCPX, covering almost all common small-scale aerial, car, and boat model batteries.

Usage Recommendations

  • Outdoors, you can use an 11.1V (3S) or 14.8V (4S) lithium polymer battery as a DC input power source to charge your devices, achieving flexible "battery charging battery" power replenishment.
  • For NiMH batteries not used for a long time, you can use this charger for slow discharge (if this function is available) or perform regular charge/discharge maintenance. After use, store the charger in a dry environment.

Frequently Asked Questions (FAQ)

Q1: Can the four channels charge four completely different batteries simultaneously?

A: Yes. You can simultaneously connect a 1S LiPo, a 2S LiHV, a 4-cell NiMH, and a 6-cell NiCd battery, and set an appropriate current for each channel independently for charging.

Q2: How long does it take to charge a 2S 3000mAh LiPo battery with the current set to 1.0A?

A: Under ideal conditions, charging time ≈ (battery capacity × 1.2) / charging current. That is (3000mAh × 1.2) / 1000mA ≈ 3.6 hours. Recommendation: For daily use, choose a current of 0.5-0.8A, which is more friendly to battery life.

Q3: What to do outdoors without AC power?

A: You can use any DC power source with an output voltage between 7-17V, such as a car cigarette lighter adapter (12V), an outdoor power bank, or a 3S/4S LiPo battery as the input power source, which is very flexible.
