Redodo 12V 50Ah Lithium Battery, Portable 50Ah LiFePO4 Battery with 50A BMS, 640Wh, Up to 15000 Cycles, Ideal for Trolling Motor, RV, Home Energy Backup, Off Grid etc.

Last winter I bought this battery in October 28 2024 used it three months. I bought a charger and a heater and other devices to regulate temperature in the compartment. If I would have bought a more expensive one I would have saved money. It is as advertised so far.

After watching many a video in search of the best, I decided on this one. It has all the bang for the buck that I was lookin for Redodo is up to par with Li Time and other well made batteries. Great instruction manual. All well packaged.

Cranking battery for my boat. Wish I had gotten this years ago. Works great and very long run time before recharging. Also much lighter than old lead acid batteries

Did what it was needed for. Put on camper great battery

Great

UpdatedFIRST of all -- As to the 4 stars. I'm a longevity test person. I haven't had the batteries long enough to ascertain whether they will have good longevity, so I'll revisit this review and update it. Short term, after a few weeks, I can say they are FIVE STAR!Zooms was EXTREMELY responsive, and we had several e-mails back and forth. I have to give them HUGE kudos for that. Be sure you understand you are NOT speaking to native English speakers so have patience. They do really well, but you have to be persistent to ensure you understand each other properly.I originally purchased two 100AH batteries I first tested separately. One definitely performed better than the other. However, that said, I noticed they both improved after subsequent charges from an AC to DC LiFePO4 designated charger. Once I was satisfied with the performance of the batteries -- after one full load test to inverter shutdown -- I then charged back up and put the batteries in parallel and connect to my solar MPPT charge controller. Here is where selecting a good quality MPPT controller and pure sine wave inverter also helps. After several days of usage and solar charging I accidently ran the battery bank down to inverter cutoff (not BMS cutoff) on a cloudy day. I did the math on the watts I drew and believe it was full or close to what I could expect considering the very low incoming charge. I got slightly over 2,560 watts over 16 hours. That's the total 1280 * 2. I expect some loss to the inverter and some gain from the panels despite overcast. I considered that a wash.Since I am fairly new to this level of solar, I've done a LOT of research, but am by no means an expert. I can only say thus far these batteries have been awesome. They're so light I can handle them without killing myself. I could NEVER haul around 100AH Lead Acid batteries. I did research and followed instructions carefully to parallel the batteries with 2AWG same size/length cables after fully charging both and letting them rest for 12-24 hours before joining. They were at 13.74 and 13.76 volts. First few charges they did NOT hold that high for 12+ hours. I can only presume it was part of equalizing across the cells. If someone knows otherwise, please post.There is a guy on YouTube that does a chop it up check on this battery and claims it's the same as CHINS but does only a little testing (my apologies for first saying none). It was interesting, but I hardly consider that doing due diligence to be helpful to your viewing audience. This is new to many of us so more in-depth testing would have been MUCH more useful. Just because something looks similar doesn't mean it will perform the same. On top of that I know nothing about whether CHINS are any good. Don't get me wrong good guy and apparently provides tons of good info.Zooms packs their batteries in truly superior manner. TWO of my box corners got badly dinged in transport, so I was worried about the batteries. However, the THICK heavy foam they pack around the top, bottom, and sides of the base and lid so the battery is like it's floating in there do a wonderful job protecting the battery. You'd think shippers would be a bit more careful with batteries, but I understand their volume is tremendous. Check yours out carefully if box is bashed up.So, if you're in the market for one of these the only warning is they do NOT contain LOW TEMP charge/discharge cutoff. You can get a Charge Controller that can take care of that if your location goes below freezing. One other item I noticed is my first shipment had the wrong load/charge location (a middle battery in a 4-battery bank) in the manual. I did my own research and figured that out connections should be on the end batteries -- one end positive and the opposite battery negative -- check the diagram provided if this is not clear. I then check the newer manual and saw they'd corrected it. There is a LOT of bad information online about where to put the load(inverter)/charge connections on battery banks. I can't speak to anything larger than 4 batteries as that's the most I researched. Zooms allows you to set up 2 banks of 4 batteries in parallel and then join the banks in series for a max -- so if you need more energy storage you may need to get the 200AH batteries to start -- but consider how much they weigh as well.I hope this info helps others. I've learned a lot and still have more to go, but thanks to some good responses from vendors I my solar journey has been positive!

Installed 4 of these in parallel on my 40' sailboat almost three years ago as the house bank. They are charged by solar, engine alternator, or battery charger depending on the circumstances. Have crossed the Gulf, spent months in the Bahamas, and months in Nova Scotia. These batteries are amazing compared to Lead acid, AGM, or Gel. Have tried them all and hands down theses are the best. Light, quick charging, and go for days, under sail or at anchor, even in cloudy weather. We spend quite a bit of time offshore and these have been flawless.

Whatever the product is explained to be capable of being, it will definitely be able to suit your application.
