24V Lithium Battery Charger, 29.2V 5A LifePO4 Battery Charger, Trickle Charger, Battery Maintainer, with Cooling Fan Multiple Protection Functions, Designed for 24V LiFePO4 Rechargeable Batteries

***Note***I bought this because I changed battery chemistry in my power wheelchair. Switched from SLA to LifePo4. Best decision I've made in a very long time. I did have to de-solder/solder some connections to use the cord from my old charger that connects to the chair. I have a strong electronics, and electrical background, so this is "At your own risk" if you try this yourself.***Review***This thing does the job... period. I read reviews that it was loud, gave off immense amounts of Wi-Fi jamming EMF, and was far enough out of voltage to be worrisome. Glad I ignored them.Voltage wise, it was dead perfect. Using my multimeter, I could see voltage rise and current drop during charge, and it peaked at 29.2volts. Exactly as specified. Initial charging current was high, with nearly the full 5 amps going in. It was nice and steady, and charged the batteries to at least 90%, but not knowing the actual cell specs on my batteries, that's a guess. There is some EMF, but no more than I would expect. I did not experience Wi-Fi disruption, and the fan was less audible than my room air cleaner.I can tell you, in my use case, this is the most ideal charger I could find. I'm gutting it, and installing it directly in my wheelchair. I will say it feels kinda cheap in the hand, but the board looks really nice, and seems soldered well. Components are all off the shelf, as far as I can see too.Between the battery change, coupled with this charger, I have my freedom again.

So far so good with this charger with no complaints, functions like it’s supposed to, fully charges my lithium battery 24v 50amp depending on usage either in half a day or less, easy to use

Other reviews show the voltage as slightly higher than rated, which would be okay—I would take that, undoubtedly dropped slightly under load—over a voltage that, even open circuit, never gets above 28.6. I was also unable to reproduce a 5-amp output from it under any condition. The best I have seen is around 4, with an average of about 3.8A. Perhaps if it was connected to a discharged LiFePo4 around 24V it would produce a little more current. The voltage of my unit would not be better, though, regardless.

Came fast, was easy to use and works well.

Worked once and hasn’t worked since. The battery is at 26 volts, but the charger light stays green and will not charge battery.

I don't recall mine coming with instructions.Basically when not on the battery it's green. When attached to the battery, it turns red, until the battery is charged, back to green.So there's no much information provided.My only complaint is the terminal clips are large, so charging a smallerLIFEPO4 battery requires a little more carefulness.

Blocks wifi around it for several meters, only feeds about 4.25A, not 5. It does work, isn't very loud, and doesn't overheat. Recommended if your on a budget and don't care about RFI/EMI.

stopped working after ten minutes of plugging it in. I think the components all look top notch but the printed copper circuit board is too thin.
