Drone Battery Charger U4 Dual channel intelligent fast charger1600W/20A

Dual channel charging:

• Similar to the U1 model, the U4 offers dual-channel charging that allows users to charge two batteries at the same time, helping to maximize efficiency and reduce the time required to charge multiple batteries.

Power output:

• With a total output power of 1600W and a maximum current of 20A per channel, the high-capacity drone battery can be charged quickly and efficiently. This high power output is ideal for high-performance drones that need to replenish their batteries quickly between flights.
• While the current per channel is 20A (slightly lower than U1), the total power output is higher, making the U4 a better choice for drones that require higher wattage charging.

Smart charging:

• The charger has an intelligent charging function that automatically detects the type of battery being charged and adjusts its parameters accordingly. This ensures optimal charging without overcharging or overheating.
• The intelligent balancing function ensures that the batteries in multiple Li-polymer batteries or Li-ion batteries are charged evenly, thereby improving battery life and performance.
