The Renogy 20A AC-to-DC Charger is an automatic, portable charger designed for 12V Lithium Iron Phosphate (LFP) batteries. It includes 12AWG alligator clips and outputs power based on the battery's voltage and current status. The status indicator light shows the connected battery's operating mode and condition. It automatically monitors and maintains the battery at full charge
When the lithium battery experiences low temperature or voltage, the BMS (Battery Management System) protection is triggered, preventing charging. This charger offers a battery activation feature that quickly exits protection mode and allows recharging. The charger's indicator light alerts you to any charging errors and provides comprehensive monitoring and protection.
The charger features a 3-stage intelligent charging design: constant current (CC), constant voltage (CV), and trickle. It can accurately identify battery voltage, automatically switching between charging modes to provide fast and efficient charging for lithium batteries. The charger's efficiency can reach up to 92%.
The charger comes with two battery charging cables, one of which has alligator clips for temporary connections. The battery charger has a wide AC input voltage range of 100-240 VAC, 50/60Hz, making it compatible with AC power grids worldwide for fast charging.
The charger includes six built-in protection features to ensure safety, including short-circuit, over-current, over-temperature, over-voltage, under-voltage, and reverse polarity protection.
The charger's indicator light will signal charging errors and provide comprehensive monitoring and protection.
The product features a patented plastic profile design for rapid heat dissipation. Its fanless design ensures a zero-noise charging experience, alleviating concerns about installation space and positioning.
Three quick steps to connect the battery and charger are as follows:
1. Connect the charger's negative output terminal to the battery's negative terminal.
2. Connect the charger's positive output terminal to the battery's positive terminal.
3. Plug the AC power adapter cable into the charger's AC port.

What kind of batteries is suitable for this charger?
1. This charger is specially designed for lithium battery charging.
2. This is a 12V dedicated lithium battery charger, where 12V refers to the voltage platform of the battery. The 12V voltage platform has one form: the battery itself is a 12V battery, and the other is formed by connecting multiple small voltage platform batteries in parallel. For example, two 12V lithium batteries are connected in parallel can form a 12V voltage.
To sum up, this charger is designed for 12V lithium iron phosphate.
Can this charger wake up a lithium battery that triggers BMS protection?
What are the accessories for this charger? What functionality does each provide?
1. Accessories include an alligater clip battery cable, and Blade Fuse.
2. The role of the battery cable: Provide one easy-to-operate connection methods to facilitate the user to realize the connection between the charger and the battery quickly
3. The role of the Blade Fuse: to provide the reverse connection protection of the battery. If the charger's positive and negative output terminals are accidentally reversed, it will burn only the fuse, and the AC charger will be safe, providing double protection.
What are the phenomena of this charger in different charging stages?
1. When the charger is in the fast high-current charging stage, it will provide a maximum charging current of 20A, and the charger's indicator light is slow flashing red, indicating that it is charging.
2. When the charger is in the constant voltage charging stage, the charging current will continue to decrease to 2A, and the charger's indicator light is slow flashing red, indicating it is charging.
3. When the charger is in the trickle phase, the charging current will be less than 1A, and the charger's indicator light will be green, indicating that it is fully charged.
