  • Good product good support.
Style: 12V 100Ah
I have owned this battery for about 3 years now. I have actually bought 2 more since for another project. The battery powers everything in my boat and it lasts forever. After about three years the battery failed to charge. Contacted support and they had me run some tests and confirm the charger type. After I send the results they sent me a return sticker for my battery. Once they got confirmation I had a new battery within a few days. They batteries are good quality and the company backs them up. Also they weren’t annoying to deal with they are friendly and supportive. Will buy again on next project. ... show more

  • Incredible for long term use!
Style: 12V 100Ah
I have been using this battery for a full year now. I live in my van full time and installed a 200 watt expert power solar system with 2-100 watt solar panels and a 20 amp MPPT solar controller. I also have the Redodo 100 ah battery and a 1000 watt inverter. The system works incredibly good. I have a 3.2 cubic foot dorm style fridge, a 32 inch TV, a laptop computer, a tablet, a cell phone and several other electronic devices hooked up to my system. By the time morning comes around I have only used anywhere from 40-60 ah at most and it takes about 5 hours of full sun to get it back to 100% charge. This battery has far surpassed my expectations. I haven't written a review about it yet. I wanted to wait a full year. This thing is easy to install and looks and works great. I just can't believe how cheap it is a year later, I paid $400 a year ago now its $270 and worth more than that. It was tested and performed better than advertised, it put out 105 ah 5 more than advertised. I would not hesitate to recommend this to anyone. This battery has passed a yearlong test in the real elements of life in a van full time. Seriously, I wouldn't buy a Battleborn battery now, why spend $900 when this battery is just as good. The proof is my year long test. Actually, to tell the truth this battery is better than a Battleborn battery because it cost far less. ... show more

  • Great price for a good battery - A review from a pool guy
Style: 12V 100Ah
I own a pool cleaning company that utilizes portable vacuums to speed up the cleaning process for my technicians. For years we had used Group 37 Deep Cycle flooded Lead Acid batteries but found the our technicians would run them completely dead every day and shorten the life of the batteries dramatically causing us to replace the batteries every 3-4 months. THESE GUYS ARE HARD ON STUFF. Usually these batteries would be warrantied but it was a hassle. We also tried AGM batteries thinking they might be better but we had the same results. It just cost more money. Several years ago I started playing with Lifepo4 batteries on my travel trailer and eventually I built an off grid system to power our shop using Lifepo4 batteries, solar, and a few inverters. I decided to try one of my old Travel Trailer batteries in the portable vacuums our technicians use and IT CHANGED EVERYTHING. Not only does it lighten the load the tech brings into the back yard but they LAST ALL DAY. The original battery, which is still in service today, was a weize branded battery which wasn't available when I decided to start switching the cleaners over to Lifepo4 (I think they are now again) as the lead acids failed and I found Redodo. Weird name, fancy colors, and a great price. I gave them a shot and I am glad I did. We now have all of our cleaners running Redodo, and knock on wood they have performed flawlessly. My technicians love them because they can work more efficiently, and every guy that has had his "cart" changed out to the redodo immediately comments on how much lighter and easier it is to move into and out of our clients back yard. Are these batteries more expensive than conventional batteries? Yes. But they have so far more than paid for themselves in productivity increases (not having to swap batteries half way through the day). Due to the discharge voltage curve my techs have also commented that the batteries never slow down like lead acid. As long as they last more than a few years I will keep purchasing them! ... show more

  • Great battery and great customer service!
Style: 12V 100Ah
The other reviews cover the pro's and positive experiences with this battery. I won't rehash. I have the 100AH. Great battery. While researching charge controllers to find a LiFePO4 compatible unit, I inquired about the compatibility of the Renogy 40amp Rover MPPT charge controller both on the Renogys' product page and at the Renogy website, after I created an account (forced). Renogy has never got back to me, to this day. I did find an answer on the Renogy product page here on amz there are USER settings for the charge controller and that they could be set to my LiFePO4. So, I then looked at the Renogy manual for that unit and it indicated the same. So, I purchased a Renogy 40amp Rover MPPT charge controller for the sole purpose of charging this battery from ~400watts (so far) of mono solar panels. Guess what, the Renogy charge controller CANNOT BE CONFIGURED to a LiFePO4 requirements! So, I contacted REDODO with a couple screen shots of the Renogy app with the settings that are available. Lillian and Jack at REDODO were the people replying promptly! The verdict was that the Renogy charge controller CANNOT BE CONFIGURED to a LiFePO4 requirements! They agreed on the best setting for that controller and helped me CONSIDERABLY! All said and done, I should have purchased a Victron MTTP controller. PERIOD. (And I am) Word of advice, no matter what kind of battery you have, DO NOT use a PWM charge controller, use an MPPT controller! MPPT's takes full advantage of solar and PWM's do not. WELL worth the extra bucks. My batteries are receiving a charge from 7:30 am to 8pm. The customer service at REDODO was great, patient and guided me to a solution. Renogy has still not replied to me or offered ANY support for my charge controller what-so-ever. I was so impressed with the REDODO 100AH battery, and the support, that I purchased another one! I am now running 24/7: my ISP's router, wifi, two desktops, my 55gal fish tank and a 5' tall freezer. For about 8 hours a day: my 4 monitors, a 55" amazon fire TV, a surround amp for said TV, intermittent use battery chargers for my lawn equipment, phone charge (from inverter USB) , laptop chargers, a fan and a soundbar. I have yet to bring the batteries down to under 80%! The amount of energy I am getting from the sun is impressive and these batteries are the perfect fuel tanks! If I had 300AH worth of batteries I could run a 5000 BTU ac unit! (solely) 1000AH would be perfect for me but, just not in the budget as I would need more panels too. Would go grid tie if that was the case anyhow. Great product + great support = A happy returning customer. ... show more

  • Started strong, should have lasted longer
Style: 12V 100Ah
I’ve had this battery for four years now and I’ve used it continually to power a trolling motor on a kayak. I’ve been careful to keep it charged over the winter and continually after each use now after my fourth year, it will not charge. I have tried to reset BMS with no luck and it will not read over 8 V. Initially, it was a great battery and worked very well and maintained a high charge. I feel like for the normal use that it has gotten, it should have lasted longer. Update to review: customer service is everything these days and this company offered to replace my almost 4-year-old battery with a new one because it was still under warranty! Excellent service. ... show more

  • Direct replacement for Ryobi Zero Turn lead acid batteries
Style: 12V 100Ah
So far so good! I got 4 of these for drop in replacement for the Ryobi 48V zero turn lead acid batteries. They fit perfect, and the mower lost 160 lbs in the upgrade! I checked to make sure the batteries voltages were balanced, and they were dead even at 13.16 out of the box. I dropped them in and put it on the factory charger. I saw something in the details that said this won’t charge fully on a lead-acid charger for a travel trailer, which I’m guessing might apply to this as well. But these are supposed to ship only 30-50% charged if I recall, and it charged up to where they green light only barely flashes within a few hours, indicating it’s full. I tested today and mowed the 1+ acre yard, then rode it around with the blades still running long enough that I could’ve mowed TWICE, which the old batteries couldn’t pull off in their prime by a long shot. It never died, never even slowed down, and it still said 100% at the end, which I’m guessing is due to a slower drop-off curve of the lead acid or something. So I gave up on trying to kill it and put it back on the charger. It took just under 4 hours for the flashing green light to start barely flashing again, so I assume it’s full changed and ready to go. The big bonus is that I no longer have to keep it plugged in in the garage after it charges, so I can keep it in the shed now and probably get 2 mows out of it before I hook it up in the garage again for another charge. The mower runs faster and stronger now too. I can go full speed into the tall grass where it used to bog down the blade motors. There’s also a noticeable acceleration increase, but I’m sure the weight change plays a factor in that as well. Anyway, so far so good! Had I known this up front I would’ve swapped the batteries when I bought the mower and sold the lead acid off as brand new to recoup some cost. With 4,000 cycles, I’ll never need to replace again anyway. Whoever I leave the mower to in my will probably won’t either! Bonus note: The batteries arrived several days ahead of schedule. I’m very happy right now! ... show more

  • A pair of Redodo 100-Ah Lithium batteries for my teardrop trailer solar system
Style: 12V 100Ah
I highly recommend the Redodo lithium (LiFePO4) batteries. I bought a pair of Redodo 100-Ah batteries in December 2022 for my teardrop trailer solar electric system upgrade project and I just ordered a Redodo 50-Ah battery in February 2023 for a portable ham radio system. I replaced an OEM 80-Ah deep cycle lead acid battery with a pair of 100-Ah Redodo LiFePO4 batteries as the heart of the solar electric system for my TAB 320S teardrop trailer. I have 500 watts of solar panels charging the 2 Redodo 100-Ah lithium (LiFePO4) batteries using 2 Victron charge controllers (a Victron 75V/10A MPPT smart solar charger for the 100-watt OEM panel and a Victron 100V/30A MPPT smart solar charger for a pair of Renogy 200-watt flexible solar panels). Some things I want to comment about: 1. With a lead acid battery, you can’t safely discharge them below 50% without shortening the life of the battery. That means my OEM 80-Ah lead acid battery had about 40-Ah of usable capacity. With the Redodo lithium LiFePO4 battery you can use 99% of the battery capacity without significantly shortening the life of the battery. So I increased my usable battery capacity from 40 Ah to 198 Ah, which leads to my second point, the weight. 2. My OEM deep cycle lead acid battery with a usable capacity of 40-Ah weighed 48 pounds, about the same weight of the 2 Redodo lithium LiFePO4 batteries with 198 Ah of usable battery capacity. The pair of 100-Ah Redodo batteries give me about 5 times the capacity for the same amount of weight! 3. Great Product Manual! I was very pleased with the 23-page product manual, written in plain English and complete with drawings and diagrams. Before you do anything with your new Redodo battery, read the product manual carefully and follow their instructions to the letter. I can’t tell you how many times I have referred back to the product manual. It’s a great resource! 4. If you want these Redodo batteries to last a long time, spend the money on high quality components including battery disconnect, main system fuse, buss bars, etc. Size your cables/wires properly using an ampacity calculator. I oversized my cables/wires to lower wire resistance and prevent heat dissipation. 5. I designed and built my system myself after watching tons of YouTube videos. I found the most useful website and YouTube channel for my needs to be explorist.life but there were many others that were useful too. I just can’t justify paying high prices for name brand lithium (LiFePO4) batteries when batteries like Redodo perform quite well for a fraction of the cost. 5 stars! ... show more

  • Warranty Scam
Style: 12V 100Ah
I purchased two batteries, September 2022 to use in my 24 V trolling motor system in my boat. I used the trolling motor for 2 black fishing trips in October 2022. I then removed the batteries , charged them up and Put away for storage indoors (haven’t used the boat or batteries) since. Fast-forward a couple years when I finally was able get the boat up again and go fishing. One of the batteries has low voltage and the bms cannot be woken up…mind you these batteries do not even have one full cycle on them. After a long conversation with the manufacturer, and proving that I have tried to wake the battery up several times and testing, they decided they will warranty the battery. OK great. The warranty is not much of a warranty at all. It is more of a pro rated discount to get you to buy another battery at a cheaper price. I had 2 options. Get a 82$ refund or get a new one at 110$ They sent me a prepaid label to send the defective battery back and I purchased a new battery for over $200 and they are going to refund me $80. Or I can keep the battery rip it apart to my own investigation and put a new BMS in it and they will refund me $82. I paid over 600 for the pair a few years back and the prices have come down considerably but I feel like I had to make some sort of review to let others become aware of their “Warranty”. The warranty is definitely misleading and its definitely not what one would expect so beware if one of these things dies and you try to get a new one. I did in the mean time Buy 2 new 100ah Watt Cycle mini w/ Bluetooth. The are very nice btw and 1/2 the size ... show more
