This AC Charger can charge charge Li-ion batteries with 14.4V or 14.8V nominal voltage and 50-300 Watt-hour (or 3-20Ah) capacity. It is ideal for charging 4S2P, 4S3P or 4S4P lithium-ion battery packs, and will work for lithium-ion batteries that accept 16.8V - 17.2V DC power input. 



This battery charger output connector is a 5.5 x 2.5mm male barrel connector.



If you need a different size connector, you can use any of our C series connector tips to transform the connector into your required size. For example, our CNT-C3 connector can transform it into a 5.5 x 2.1mm connector. Our CNT-C25 connector can transform it into a 4.0 x 1.7mm connector.



Features:

• Fully automated 3-stage charging process controlled by MCU
• Automatically cut-off output power at ending of charging process.
• Small current in pre-charge stage and larger current in main charging state. This will optimize the battery pack`s cycle life.
• 4 LED lights indicate the battery's power level from 25-100% .
• 100V-240V AC input for worldwide power support.

Safety Protections:

• Over Voltage protection
• Short Circuit protection
• Polarity error protection
• Over power protection

This charger has 4 LED lights to show its power level during the charging process.
