The media could not be loaded. Update : Oct. 21, 2024. Based on my observation, the charger indicates "FUL" when my 12v 100Ah LiFePo4 battery reaches 14.7 volts [3.675v per cell]Update (again) Info : Almost a full year using this charger and still working and doing great. One thing I forgot to mention. A "con" about this charger is that once the battery registers fully charged, all 'charging' information is gone. (While charging...) It tells you how many amps are going into the battery as well as how many amps have already gone into the battery but once charged up...you won't know the total amps it put in because just shows "Full"....that's it... no voltage reading, and no total amps (when DONE charging). This kinda sucks but my battery is still in good shape.Update Info : I had a battery at 62% state-of-charge. On the Low charging setting, I was getting 2 Amps at about 30 watts. On the Medium setting, I was getting 15 amps at about 207 watts. On the High setting, I was getting 19 amps at about 250 watts. So I'm going to call this HTRC P25 a 250 watt (LiFePO4) battery charger.HTRC P25  Model No. P25/25AMP/N25Date : 5Nov2023Alligator clamps open to a maximum of 1 inch.  Clamps to XT60 cable is about a 12AWG wire and about 38 inches long (from the charger).  Clamps are hard plastic (may be prone to cracking/breaking upon hard impact).  AC cable is about 10ft. long.  There are no mounting options via screws.  There are 4 rubber feet.  Mine came with 2 all copper (not tinned) M8-5/16" ring terminals with open crimp end connections that could probably fit up to 4AWG wire (6AWG can easily work -see attached pic).  The copper ring terminal is marked '60A' which I'm assuming means 60 amp max current.  It uses less than 3 watts just plugged in -'phantom draw' (no battery connected - according to my Kill-a-Watt only 1.3 watts / 2.5 VA).  From the AC outlet to battery clamps is about 13.6 feet length.  I got 2 amps on low charge setting , 15 amps on medium setting and 18.8 amps on high setting.  There are only 4 selectable settings.  I have not tried using the 'Repair' setting.  The lcd screen does light up.  It doesn't come with a case.  I have not tried charging a 24 volt battery because I don't have one to test it on.  I paid $ 69.90USD.  I hope my information, pics and video was useful to you.  Thanks Amazon employees/drivers and HJDZUS - HTRC Store for a satisfactory purchase/product !

Purchased this to better charge a 300ah 12.8v Lithium Iron Phosphate battery powering our motorhome. Motorhome charger is older (2004) and only charges to 13.6v but wanted a better newer charger to better charge up to 14.6v at a reasonable cost. This charger was the best I found that was a reasonable price and charged up to 14.6v without taking too long to charge because of the 25a max charge rate. Total charge time from 10% charge up to 100% was only about 15 hours because to battery was so low. I like the small size and large cables, never overheated and the LCD readout gave me continuous charging status and was easy to read. Would definitely recommend this to anyone looking for this type of charger.

Reliable and easy to use, but a bit noisy.

I'm going to be honest. Originally I thought this product was a re-chargable battery pack that can be used to jump start cars, ATVs, etc. This is actually a trickle charger. Pros: Lightweight, easy to use, large screen that easy to read, detachable jumper cable things.Cons: It is a trickle charger and not a battery pack used to jump-start cars.Seriously, though this product is great to slowly re-charge a battery. We are restoring an old truck and trying out different parts and making minor adjustments then attempting to start the car over and over again runs the battery down. Every evening when we are done working on the car we attach this charger and by the next day it is ready to go again.

Worked OK for a few months. I put it in drawer and pulled it out about six months later. Now all batteries are "FULL" and no charging or battery repair happens. Tried different batteries, outlets, settings, etc. "Support period" ends after 6 months. Buy a known name brand.

I originally bought this because I was adding a lithium battery into my camper and the stock charge controller doesn't provide enough voltage to fully charge it. While I originally intended on just tossing it in my camper and calling it a day, I've ended up using this thing to revive a couple batteries that just weren't holding the capacity they were before (I have no way of determining the actual amperage available in the battery, so this might be a bit subjective, but after a charge and repair cycle a battery that could barely turn over an older truck handled it without even breaking a sweat).I also found a cable that can go from this charger's port, right to the solar input on the side of the camper so no more opening/closing the battery box when I need a top off. Completely happy with this charger.

It charges my 20A lipo and 5A gel cell batteries just fine. I leave it connected to the 20A Lipo and it never trickle charges after completing any charging mode. I haven’t checked it using other battery types.

I'm upgrading my off-grid solar system from a 100AH to a 200 AH LiFePO4 battery - so I bought a second battery and needed to charge and equalize the two batteries together before connecting them to the solar charge controller. Operation is very simple - Connect the alligator clips to the battery posts, set it to "Medium" and let it do its thing - I figured it's a new battery and after several hours I went back and it was finished. Did the same with the second battery, and after that was fully charged, connected them in parallel, and connected the charger again, to let them equalize. Finally connected back into the solar charge controller. I'll be upgrading the system to a 24V inverter soon, and when I do that, I'll be equalizing the batteries every few months, as that's recommended by the battery manufacturer. Overall this battery charger is a great addition to my solar system. It'll also work if my car battery needs a boost as well, so an added benefit.

This unit goes into an automatic program to recharge the 12V battery and works even near freezing temperature. The cooling fan is audible and runs even at ~ear freezing temperature, a little bit strange. It took about 12 hours to recondition the battery and recharge it to full power.

I did not like that the ac mains plug was American therefore having to purchase a adaptor and only in the instruction booklet it states that you cannot charge lithium batterys without a management system, both of which incur an additional cost to use this charger as implied in the add. I probably would not have purchased the charger if i had known this beforehand. I will now think twice before i purchase anything else.Regards Terry

Done many of batteries that wouldn't hold charge this unit brought back to life

At first, I gave this product a glowing right now, but after using it for over a week I found that my other chargers were still charging, but this one would say full and shut off. Today I watched it more closely and I switched it onto a different battery system and I saw the reason it shuts off at 27.1 V. It should charge up to at least 29.2. It’s supposed to charge at 14.6 V which it may but it shuts off too soon and doesn’t charge your battery fully.

Just plug and play.As simple as that!
