Our take on the Greenoe 12V 20A LiFePO4 Battery Charger

The Greenoe is a 20A smart charger built only for 12V/12.8V LiFePO4 deep-cycle batteries. It runs a three-step CC/CV charge, can wake a 0V dead battery, and takes 100-240V AC input, so it works on US and overseas mains. Its aluminum case and internal fan handle heat at full output, and it has both M8 terminal posts and a 50A Anderson connector. Against generic 10A chargers it charges roughly twice as fast; against Victron and Renogy units it lacks Bluetooth monitoring and adjustable charge profiles.

About the Greenoe 12V 20A LiFePO4 Battery Charger

The Greenoe 14.6V 20A smart charger is made for 12V/12.8V LiFePO4 deep cycle batteries. It charges at a stable 20A and accepts a wide 100-240V AC input.

The casing is aluminum alloy, with an internal cooling fan that disperses heat during high-power charging. The charger uses three-step CC/CV smart charging and can reactivate a dead battery at 0V. Multiple built-in safety protections guard against common charging faults.

It has both M8 and 50A Anderson output ports. A US plug comes pre-assembled, and a full accessory kit is included.

Questions and answers

Will it charge a lead-acid or AGM battery?
No. It is built for 12V/12.8V LiFePO4 batteries only. Its charge voltages suit lithium cells and are too high for lead-acid.
Can it revive a completely dead battery?
Yes. It supports 0V reactivation, so it can bring back a LiFePO4 battery whose BMS has shut down from deep discharge.
How long does a 100Ah battery take to charge?
At a steady 20A, a fully drained 100Ah battery takes about 5 hours. Larger banks take proportionally longer.
What connections does it have?
It has M8 threaded terminal posts and a 50A Anderson connector, so you can use ring terminals or an Anderson plug.
Can I use it abroad?
Yes. The 100-240V AC input covers most mains voltages worldwide. You would need a plug adapter for non-US outlets.
Does it come with cables?
It ships pre-assembled with a US plug and a full accessory kit, so it is ready to use out of the box.
