Great Quality, Sturdy, light and works as expected.
Size: 2 Pack 12V 100Ah Style: Group 31- Standard
I have purchased several batteries of this brand over the years and haven't been disappointed. All keep working good and have the same capacity as new. The origional ones came with un advertised connecting cables, the new ones don't. I use these for backup batteries for my home server, for my boat inverter, for my motorhome extra power, My boat bow thruster, and for my electric dingy motor. Have also purchased Redodo chargers, converters and inverters. They need to make a UPS inverter to go with their great batteries. My APC UPS backups only last long enough to shut down your computer (when they work). Batteries only last a year or two and the units keep failing when you need them most. ... show more

Great lead acid replacements
Size: 2 Pack 12V 100Ah Style: Group 31- Standard
Bought two of these for my 24v trolling motor. I have used them 4 times so far. I followed all of the instructions to balance them. I also bought a new battery charger to go with them. They last longer than the old lead acid batteries ever did. I have been on the water a couple of times and have used the trolling motor extensively and the battery meter never dropped. I just ordered a third battery (50ah) for the electronics and assume it will perform as well as the others. Redodo has reached out multiple times to provide shipping details, and confirm receipt. I have not had to contact them for support but based on the communication at this point I believe they would be responsive. UPDATE: 9 months after purchase and these batteries are performing extraordinarily well. I have used them to power my 24v trolling motor all day and I never see the indicator at less than full. Typical operation for me is running the trolling motor (MinnKota Terrova) at about a “3”. I also use it in conjunction with a gas kicker motor to maintain heading and it will run from a 1.5 to a 4 speed normally. I recently went on a fishing trip to Lake Saint Clair in Michigan and fished 13 hours the first day and 12 hours the second. I charged them over night with a 5x3 bank charger and the trolling motor never stopped. I highly recommend these batteries. ... show more

RV compatible
Size: 2 Pack 12V 100Ah Style: Group 31- Standard
Over two years ago, I replaced the two lead acid 12 V batteries in my fifth wheel with these and have been extremely pleased. There is enough power to operate my inverter on an all day drive while running a large residential refrigerator and whatever 12 V appliances the rig has. At any point I am able to crank my 5500 Onan generator also. I did contact the RV manufacturer prior to installation and the tech highly recommended lithium batteries. *** check your converter/charger for compatibility. I was able to flip a switch and charge the lithium batteries. Not only are the batteries much lighter, but they solved my electrical problems. ... show more

Good batteries, but one of the four has failed.
Size: 4 Pack 12V 100Ah Style: Group 31- Standard
I like these batteries, I have 8 of them total. However, my 48 volt setup has been acting weird, so I tested all the batteries, one was at 10.5 volts, causing that bank of 4 to not charge, and only one bank of 4 was working, which dropped my power from 48 volts, 200 amps, to 48 volts, 100 amps. So I need to replace one battery. It should still be under warranty, but I can not seem to find the way to do it, and I do not want to pay to ship it back. I have the asurion product protection warranty, so I should be covered, Can I get one replacement battery sent to me? Thanks, and I will send it back if necessary. ... show more

Do it!! You will not regret it!
Size: 2 Pack 12V 100Ah Style: Group 31- Standard
Let me start by saying that I’m a hard sell. I bought 2 of the 100ah group 31. I had these batteries in my cart for over a year. I have had these batteries on my boat for over a month now and have already put them through the wringer. They are amazing! I wish I would’ve done it two years ago. By going to lithium I gained almost .5 mph, but the biggest improvement was the increased power that is sustained all day with no power loss 10 out of 10. I highly recommend by switching to lithium I was able To remove over 100 pounds of weight out of my boat. That alone is worth the change to lithium. ... show more

Flawless Performance
Size: 2 Pack 12V 100Ah Style: Group 31- Standard
I have never written a review on any product that I’ve purchased, but these Redodo batteries’ performance far exceeded my expectations that I felt I had to share my experience with them. I connected 2 Redodo 100ah lithium batteries in parallel for a total capacity of 200ah at 12 volts. During a 3 week road trip down and around Baja Mexico camping on the beach in a converted minivan the batteries performed flawlessly. I was able to charge the batteries while driving using a DC to DC 40 amp lithium battery charger to keep them fully charged. However, I camped at one beach for over a week without any driving and I used less than 30% of the batteries’ capacity. I have the batteries connected to a 2,000 - 4,000 watt power inverter and use a coffee maker, microwave, induction cook top, waffle maker, and hairdryer for my wife. After camping for over a week without any additional charging I still had over 70% of the batteries’ capacity left. The two batteries arrived a few days after I ordered them and they were well boxed in heavy duty boxes with solid styrofoam sheets inside as packing material. Even better than the performance of the batteries is the performance of Redodo Customer Service. Exhil, Alice, and Lillian were exceptional. Exhil contacted me to let me know when the batteries were shipped and when I should expect delivery. .Alice contacted me after the batteries were delivered to make sure that they arrived promptly and undamaged and that I was satisfied with the product. I’ve purchased hundreds of product on Amazon and have never had a company contact me after delivery to make sure everything was OK with the product and that I was satisfied with it. Since I have never used lithium batteries before I had a few questions which were promptly answered (usually within hours, not days) by Lillian. I’ve been in contact with Lillian quite a few times and she has always answered promptly, accurately, and friendly (not like most customer service representatives who make you feel that you are bothering them with your inquiries.) Bottom line, I highly recommend Redodo batteries not only for their products but also for their Customer Service. ... show more
