Redodo 14.6V 20A LiFePO4 Battery Charger for Lithium Iron Phosphate Battery, Support Fast Charging, High Charging Efficiency Designed for Deep Cycle LiFePO4 Battery Charging

I honestly haven't used this a lot, as the battery is mostly for emergencies or for "Parks On The Air" (ham radio), which I haven't done in quite awhile. I bought it to rapidly charge my Redodo 100AH battery. It does what it says, and does it quickly. I also love the giant PowerPole connectors. Prior to buying this, I was using a NOCO 10A charger that they said was rated for LiFePo batteries, but man did that thing get HOT. The fan on this Redodo charger is kind of loud, but it's not like I charge batteries next to my bed, so no complaints about the noise.

Awesome charger

Bought the fast charger and 100ah battery for a backup generator to run at night when camping or emergency outages. So far beyond my expectations. The battery holds a charge for a month and doesn’t lose charge. Charger is fast and has a built in fan to prevent overheating

Item exactly as described, arrived in timely fashion. Would certainly purchase again, easy to use

This is a nice unit I picked up to charge my 100AH battery on my 19' sailboat which powers the lights and one USB charger. Most send allegator clips, these folks send an Anderson connector. Be aware of this is you are going to be going across multiple distinct batteries. An this type of connector is superior and locks in tight. That said, unless you buy additional connectors, you will have to pull that off and screw it onto the next battery. Do yourself a favor, buy a few extra connectors and one set of battery allegator clips for when you need them.

Bought this to keep my SOK 12V/100aH battery topped off until I can get my solar panel installed and wired up. So far, so good...using my clamp-on ammeter the charger is putting out nearly 21 amps (20.73). Reviews for other similar chargers showed charging rates in the 18 amp range. Totally satisfied. Will update if anything unexpected happens to the charger.

I tried 3 other “lithium compatable” chargers that would not charge my new lithium battery. This one worked well!

I expected the charger to show recharging progress, but it does not. Additionally, I can fully charge my Redodo 100Ah battery, turn the charger off, and then plug it back in after a short while (even without using the battery), and it still takes well over 10 to 20 minutes before it shows a full charge again. Lastly, it’s quite loud during operation. I decided to keep the charger because it does work, but considering the charger price and the way Redodo promotes their products, I’m disappointed.

Works as described, charges very fast, just wish there was some way to mount it on a wall or under a shelf…

Great charger. Cooling fan creates a bit of noise. Very well built.

I have a 100 amp Redodo Li Fe Po battery servicing as a house battery on my 32' sailboat. Though the solar panels keeps it charged up, nice to have a plug in back up. So far, the Redodo 14.6V 20A Fast Charging LiFePO4 Battery Charger is working as it should. Great price all things considered.

Works extremely well

Great lithium battery charger.
