The Renogy 12V 20A/24V 10A AC-to-DC LFP Portable Battery Charger is a plug-in charger for lithium iron phosphate batteries that automatically charges and then holds the battery at full. This listing is the 12V 20A version, a practical way to keep LFP batteries ready using a standard 100–240VAC power source.

Charging runs through three intelligent stages at more than 89% efficiency, easing off as the battery fills so it is not overworked. A lithium activation function can wake a battery whose BMS has shut it off for protection, and the unit guards against short circuits, overcurrent, overvoltage, overheating, and reverse polarity. With a 20A charge rate, a 100Ah lithium battery can be fully charged in about 3.5 hours.

The fanless housing sheds heat quickly, and the charger is ready to use out of the box, with ring terminal and alligator clip cables plus a mounting bracket and screws for a fixed installation.

What batteries is this charger for?
It is made specifically for 12v lithium iron phosphate batteries, either a single battery or batteries connected in parallel.
Can it revive a battery that has gone into bms protection?
Yes. it has a lithium battery activation function that can re-activate a battery after its bms protection has been triggered.
How long does it take to charge a 100ah battery?
At 20a, a 100ah lithium battery takes about 3.5 hours to fully charge. the battery's maximum charge current should be 20a or higher.
What do the indicator lights mean?
During fast charging and constant-voltage charging the light slowly flashes red; in constant-voltage mode the current tapers down to 2a. when current falls below 1a in the trickle stage, the light turns green.
What accessories come with it?
Renogy lists ring terminal and alligator clip battery cables, a blade fuse that provides reverse-connection protection, and a mounting bracket with screws.
