Redodo 12V 100Ah LiFePO4 Battery, Rechargeable Lithium Iron Phosphate Battery, Built-in 100A BMS, 4000-15000 Deep Cycles & 10-Year Lifetime, Perfect for RV, Camping, Solar Home etc.

I have two main uses for this battery:1) Emergency power2) Backup power for my amateur radio stationThe battery I purchased allows you to connect to it from your phone via wireless technology to an onboard battery management system (BMS). I love being able to see real-time stats on the battery, especially the estimates on how much time the battery will continue to produce power at the current load.The size of the battery is very reasonable given how much power it stores. It's capacity is AWESOME. This type of battery is designed to be light weight with a great deal of power-bang for the buck. I feel it hits all of those design goals. Battery technology has come a long way since I was last buying a solar panel and a battery.I am VERY happy with this product. It's price, performance, and responsiveness of the seller have all exceeded my expectations.I purchased separately a charge controller (also by Redodo) and a pair of 100 watt solar panels. I am pleased with how the entire setup works. By my calculations, if I have both panels in operation I can fully recharge this battery in a day.I also added an inverter to the system. I can hook that up to the battery and run a/c items (anything you plug into a wall outlet).I also purchased separately a battery charger...one that plugs directly into the wall. I purchased the Redodo charger. You can use other chargers, but be sure to get a charger designed for this battery technology (lifepo4).Don't forget the cables! Solar panels and charge controllers have a standardized plug. My solar panel cabling all uses that plug (sorry the name escapes me).I used Anderson 50 amp power pole connectors on the other components (wall charger, inverter, and connections to my amateur radio gear). Thinking about cabling and connectors before hand will go a long way to easing your system integration/construction.I probably went overboard on the specs for this system, but so be it...I'm an engineer. This battery is the heart of my entire "solar generator" system and to date I am THRILLED with its performance.

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!

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

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.
