Review: Could be improved for the money - Okay good charger but the cooling fan doesn't need to be running flat out in cool weather it should be pwm controlled not all out noise all the time. A resistor will be getting added to slow the fan speed to a reasonable speed Review: Funciona con baterias de Litio - Resultó muy util.

Is anyone else's?** A: yes, it is loud. I have the 60 amp. I thought mine was malfunctioning, returned and replaced. same volume. head's up, the led indicator light failed on both units I owned within a month. on the plus side it's still working flawlessly otherwise after 12 months of constant use. **Q: Will this charge 4- 12.8volt 100ah (400ah total) life P04 batteries wired in parallel?** A: I would assume so. It will max out it charging capabilities and will take longer to reach full charge. I have it charging (2) 100 amp Life PO4 batteries that are about 8 years old. It works fine **Q: Are there other types of battery connectors that can be purchased for this charger? ....like eyelets or lugs?** A: I doubt it as it appears to have a proprietary plug on the charger to connect the supplied cable with alligator clips and they provide 2 copper ring connectors qhere I presume you are expected to cut the alligators clips off and crimp on the provided rings. If they expected you to use rings, then i suspect they would have provided a second cable to interchange. Keep in mind that you essentially have a + and - cables that you can cut and splice on any connector you want. I spliced an ASE connector in line between the alligator clips and then installed wires with ASE connectors on one end and rings on the other end to all my other batteries so now i can just quick connect to any battery that needs charging. **Q: Can it charge 2 12 volt in series 24 volt mode** A: Yes, please feel free to use it. Thank you for choosing P20 smart charger! ## Customer Reviews ### ⭐⭐⭐⭐ Could be improved for the money *by M***. on 25 April 2023* Okay good charger but the cooling fan doesn't need to be running flat out in cool weather it should be pwm controlled not all out noise all the time.

Car Battery Charger,Trickle Charger, Maintainer/deep Cycle Charger,12V/20A and 24V/10A I bought two of these from Amazon to charge up my LiFePO4 batteries for my off grid cabin setup at 9000’ in the Colorado Rockies. They work amazing – charging those to somewhere around 14.4-14.8 volts automatically. Not only did they charge my LiFePO4 batteries, they also revived my deep cycle L-16 batteries that the LiFEPO4 batteries replaced. The L-16 were the standard for solar a few years ago, and my L-16’s are about 6 years old on their last legs, needing constant monitoring, gassing off of acid, and needing to be refilled with ever scarce (during the pandemic) distilled water. The charger revived 3 of what I thought were dead L-16’s (and topped off the other 5). I’m now going to move those down to my garage to use in another solar application that’s not so critical (cabin itself is critical for furnace heating on propane when we’re not there, therefore the swap out to LiFePO4’s from L-16’s). The charger itself: display is very bright, buttons are well made, it remembers which battery type you last charged although very easy to set that, you can select the amps for charging which is great for low amp charging of ATV or Snowmobile AGM smaller batteries. Last weekend I had to move my LiFePO4 batteries inside due to severe freezing conditions and used the two chargers to top them off and make their voltage reasonably close to the other LiFePO4 batteries in the system before placing them back on the solar/gen-charger system. Worked perfectly. Also, since my main system is 24v, I can hook the charger up to the main battery bank on the main pos/neg to charge the whole system if needed. The chargers also have that recovery mode for Deep Cycle Lead Acid batteries, and that also works for normal car/truck starting batteries as well. Recovery mode on mine took about a day for it to cycle the lead acid cells – you can see/hear the acid bubbling when it does it and need to keep eye on acid/water level every so often as it recharges them, like I said I though they were deader than a door nail and they are now revived. I’ve looked at other multi-battery-type chargers, and these chargers fit the bill for my dozens of batteries and currently 4 different battery types – LiFePO4, deep cycle, starting, and AGMs – the mode button allows you to select which battery type for the proper charging voltage and cycle. I’ll probably buy a few more for use at my main house in the city. ## Frequently Bought Together - 20-Amp Smart Battery Charger,Lithium,LiFePO4,Lead-Acid(AGM/Gel/SLA..)
