DC5V 1S Lithium Battery Compact Balance Charger

Multi-Port 1S Parallel Charging: Equipped with multiple dedicated 1S output ports, allowing simultaneous charging of multiple 3.7V single-cell LiPo or Li-ion batteries (such as micro RC drone and model aircraft batteries).

Standard DC 5V USB Power Input: Powered conveniently via a standard 5V DC USB power source (USB wall adapter, power bank, or laptop USB port) for easy field and bench power replenishment.

Independent Channel Voltage Monitoring: Each charging port functions independently to monitor cell state and safely manage charging current, preventing cross-cell imbalance or overcharging.

Compact & Ultra-Lightweight Form Factor: Small-footprint control box design easily fits inside RC field bags, toolkits, and portable flight kits without taking up valuable space.

Onboard LED Charging Indicators: Dual-color LED lights for each charging channel provide clear visual feedback during charging (active charging vs. full charge status).

Plug-and-Play Micro Connectors: Features pre-wired JST / Micro-JST style connector leads for effortless, solder-free connection to micro RC battery packs.

Housing & Enclosure Style: Lightweight, durable ABS plastic casing housing the internal balance charger PCB.

Contact & Terminal Style: High-flex silicon-insulated lead wires with gold-plated micro pin connectors and standard USB power input cable.

Technical Specifications:

Input Voltage: DC 5V (via USB).

Output Voltage: 4.2V DC per channel (-+ 1%).

Charging Current: Approx. 350mA–500mA per channel.

Target Battery Chemistry: 3.7V 1S Nominal Li-Po / Li-Ion.
