RCGCBC Battery Charger 0-25A,12V/24V LiFePO4 Battery Charger for Lithium,Lead Acid,AGM,RV,Marine,Boat, and Deep Cycle Batteries,9 Stage with Pulse Repair,Smart Car Trickle Charger & Maintainer

I bought two 300ah LiFePo4 batteries for my motorhome. I was told to make sure the batteries were fully charged before first use. These were easy to connect, brought the batteries to full charge and the charger is stored in my equipment bay - ready for next use. I will use the charger after winter storage to slowly recharge my batteries.

I bought this charger for my car. It turns out to be a very good product and has exceeded my expectations in terms of performance and reliability. Specifically, it performed better than other chargers I tried before in reparing battery. The voltage became 12.6 after charge from less than 12 originally. The charger has a robust build quality that gives me confidence in its durability. It's designed to be user-friendly, with clear indicators and simple controls that make it easy to use right out of the box. The shipping is also fast and it is totally a pleasant shopping experience.

This battery charger is a beast! It charges my car crazy fast. The portable design makes it easy to carry around, and the trickle charge feature is perfect for keeping my motorcycle battery topped up.

Such a bummer that this unit cannot get anywhere close to advertised charging rate — it is otherwise a very nice unit! Ironically, on the "mid" setting it seems to hit the advertised 15A almost perfectly, 14.9A indicated on unit and 14.85A measured (see photo). Setting the unit to high does almost nothing othewr than potentially raising temps — the most I get is 17.5A measured, with 19.1A indicated (which is fake). Other testers have found the same problem with the rebrand of this unit (not sure which is the original, this or Haisito — seems like the HTRC labeling has taken over, at least on Amazon), bummer that they did not fix the problem. As it stands, it is COMPLETELY FALSE ADVERTISING! I believe their P20 unit does a better job as it at least gets closer to 20A than this unit which was supposed to do 25A but can't pass 17.5A. The irony is that this is not a bad unit at all, despite its one major flaw — I would have given it 3.5 stars if possible; had it reached 24A+, this would be a 5 star unit (at the price it is sold). Battery used in test is a 12.8V 150Ah LiFePO4.

It charges my 12V LiFePO4 batteries quickly without overheating. The 25A output is powerful, making it a great choice for deep-cycle batteries. It automatically detects whether I’m using a 12V or 24V battery and adjusts accordingly. The trickle charge feature is great for maintaining batteries without overcharging. The screen clearly shows the charging status, voltage, and battery level. It’s easy to read and helpful for monitoring progress.

This little charger has most all of the features you need, with a simple interface, without a bunch of gimmicky stuff you don't need. It automatically senses the type of battery that's connected - so there's no messing around with manual selecting - and it adjusts the charging profile accordingly. I've used this charger on a 8Ah LiFePO4, a 9Ah Li-Ion battery, and a couple 12v SLA batteries, and it worked very well. The instructions for turning it on are counter-intuitive to most any other charger I've owned; first you plug the charger into the wall socket, then select the charge Mode (Low, Medium, High, or Repair), THEN connect the charger clamps to the battery terminals. Typically, I'd hook the battery up to the charger, then turn it on. But with the built-in reverse polarity and short detection circuitry, it makes perfect sense that the charger needs to be powered up to detect the battery type and state. The fan noise is noticeable, but not objectionable. I'm using it in the garage, so I don't mind the noise. Unlike other reviews I'd read, the fan on ours did shut off once the battery reached full charge. The only negatives (sorry, bad battery pun) I see are: - The instruction sheet is a tiny 3" x 5" pamphlet with VERY tiny text, in multiple languages. Having a larger booklet would be much easier for old eyes to read; - The clamps are attached to the cable harness and uses a dedicated plug to connect to the charger. The clamps are bulky and are prone to popping off smaller spade terminals. It would be great if there was a spare harness included with just the plug and pos/neg wires. That would allow the user to install their own connectors for their application (spade lugs, barrel plug, powerpoles, etc.). - I actually found connectors on Amazon that appear to be the identical plug! I will be buying a set of them and making various terminations for my different applications. https://www.amazon.com/Pairs-Female-Connector-Silicon-Battery/dp/B07QH249CR/ref=asc_df_B07QH249CR/?tag=hyprod-20&linkCode=df0&hvadid=361104274063&hvpos=&hvnetw=g&hvrand=15094688860884837255&hvpone=&hvptwo=&hvqmt=&hvdev=c&hvdvcmdl=&hvlocint=&hvlocphy=9019489&hvtargid=pla-807965256474&psc=1&tag=&ref=&adgrpid=76397916420&hvpone=&hvptwo=&hvadid=361104274063&hvpos=&hvnetw=g&hvrand=15094688860884837255&hvqmt=&hvdev=c&hvdvcmdl=&hvlocint=&hvlocphy=9019489&hvtargid=pla-807965256474

Good

Thing lasted 2 months before it stopped working. Tried working with Amazon and basically tell you you s*** out of luck. I remember adding The two-year warranty but they said I didn't do it so your taking a chance ordering from these people. Usually don't have a problem with Amazon. They must just be in a bad mood or something.

Excellent charger. Automatically detects your battery type. You set the charging rate, high, medium or low. It has a setting for recovering a "dead" lead acid battery. I charge both lead and Lithium batteries with it, no problems whatsoever. Has automatic shutoff when done displaying the battery is full. I highly recommend this item.

Works very well

Works great, love the fact it analyzes the battery first.

Charges lifepo4 and my truck battery very well. Very happy

Charger stuck in Off mode and will not move.
