This charger was tested on a 150 Ah Eco-worthy ECO-LFP1215003 battery. The data is from the battery BMS captured by a Python program.
This charger comes with an Anderson connector with terminals attached. There are no operating controls; you just attach it to the battery and plug it in. A red light comes on and a loud fan starts up. After a few minutes I checked and none of the cables or connections got hot, so the supplied wiring is good for the full 20 amps.
Using the BMS instrumentation and a Kill-A-Watt, I got these numbers: (see chart)
118.1V 4.58A in, 327 watts in, 544 VA in, power factor 0.61 (no PFC)
13.55V 19.23A 260.57W out, 79.7% efficiency
A clamp-on meter showed 21 amps, which would give 87% efficiency.
Assuming 20 amps, 82%. The efficiency is somewhere in the 80s.
The charger holds 20 amps until the battery charge is nearly full, then the voltage starts to rise and current ramps down. The charger shuts off below 14.6V output. The battery BMS did not trip. The charger light turns green and the fan stops. Standby power consumption, once fully charged, measured 5 watts.
Altogether a good charger. Fan is loud and efficiency could be higher.

Having a good, reliable charger (or two, or three) for LifeP04 batteries is an important detail in maintaining the health of your battery investment. As we use the power stored in the batteries, we need to recharge them. Obviously, my first choice for charging would be through solar panels and a charge controller. This allows the batteries to be recharged by the sun, incurring no expense from the electrical grid.
However, there are requirements to charge the batteries when there is insufficient sun/solar, and to maintain the state of charge and state of health of the batteries.
Every kind of battery has specific charging requirements, and LifeP04 batteries charge at a higher 14.6V compared to traditional lead acid batteries.
I just received two NewtiPower 300Ah 12V batteries for an off-grid solar system I built. I have one of the batteries charging with a Noco Genius 10 charger (10 Amp), and the other battery is charging with this E-Fast 14.6V 20 Amp charger. Both batteries came delivered charged at around 75% capacity, so just getting each of them topped off at 100% before connecting them in parallel for a 12V system, providing 600 amp hours of energy storage. I checked each charger output with an ohm meter, the Noco Genius 10 was charging at 11.2 amps, while the E-Fast 14.6V20A was charging at 21.2 amps.
With quite a few LifeP04 batteries now, I’m glad to have this dedicated 20 amp charger. This is the second solar system I currently use. The other system built a few years ago has five (of the much more expensive) Battle Born 100 AH batteries. So, having independent battery chargers is important for periodic single battery maintenance. The other two AC chargers I have available are two separate Xantrex integrated inverter/charger units. One of them charges at 50 amps, and the other one charges at 100 amps. I like this unit coming in at 20 amps charging power, and that it has a dedicated charging profile for LifeP04 batteries (no changing settings..connect it, plug it in and know it’s set up correctly for the battery charging).
I consider this 20 amp charger a “trickle” charger for these larger 300 amp hour capacity batteries. It is a good all around charger for any LifeP04 battery. It does have an internal fan that runs to keep the unit cool. I have it charging in the garage when in use so it is not a concern, but something others may want to consider? When connected red LED means its charging…green LED means it’s charged. The charger is designed to follow the lithium charging stages “bulk, absorb, float”. So, there is the protections in place to not over charge when remaining connected to AC power after fully charged.
LifeP04 batteries have a specific charging requirement and having a dedicated charger that can maintain them is mandatory. This is a good option for a 20 amp LifeP04 lithium battery charger.

This looks to be a well-regulated smart charger for Lithium polymer batteries, capable of delivering a 20 Amp maximum charging current to bring the batteries back to full charge in a reasonable amount of time.
The heavy-duty “Anderson” connector which is an industry standard for battery systems appears to be well made and shows excellent contact surfaces and minimal resistance when slid onto the charger’s output cable. The product page rates it at 50 Amps, so the 20 A output of this charger should never pose a challenge to it.
I was able to test some of the charger’s protection functions and found that it has an accurate no-load output of 14.61 Volts and it will not deliver any significant amperage when it reaches that terminal voltage.
Under load, it spins a very effective cooling fan, but one that is quite loud in operation. Considering its small 50mm (~2”) diameter, it logically spins quite fast to effectively cool the charger’s internal circuits, as 20 Amps is a considerable output for a charger this small in size.
The aluminum case of the charger measures 8 ½ X 3 ½ X 2 ½ inches (~216mm X 89mm X 63mm) so it would mount conveniently in the battery bay of a motor home, for instance. Unfortunately, no mounting holes or keyholes are provided, so you would have to construct your own straps to hold it down.
Both the power cord and the charging output cord are approximately 32” (81cm) long, although the pictures on the product page have them listed as much longer at nearly 48” (120cm), which I feel would have made them more convenient.
It delivered its rated 20 Amps to a depleted battery and began to taper off appropriately as the battery’s terminal voltage rose, delivering a reduced 14 Amps at 14.28 Volts, 8.5A at 14.5V, and just under 2A as it closely approaches 14.6V, its rated maximum charge voltage.
The red charge indicator LED turned green at exactly 14.6V and the fan turned off, but the charger continued to deliver some Amperage from about .7A at 14.60V that further tapered off as the battery terminal voltage rose a little bit more. At 14.62V the charger was delivering a scant .2A, showing very good charge regulation once it entered the “float” stage.
I believe that this charger will be effective at charging and maintaining LiFePo batteries and if it didn’t have cords shorter that advertised and a quieter fan, I would have easily given it 5 stars. As is, I believe that it is worth the price because of its close regulation and because it easily met its rated 20A output.
