A:
Yes, LiFePO4 is an inherently safe and extremely stable type of lithium battery. All Redodo LiFePO4 batteries are equipped with an internal Battery Management System (BMS) that offers comprehensive protection against under-voltage during discharge, over-voltage during charging, over-current during discharge, over-temperature during both charging and discharging, and short circuits, thus preventing damage to the battery cells. Additionally, Redodo LiFePO4 batteries have undergone rigorous testing to ensure they are free from the risks of fire and electric shock, even in harsh environments.
Q: Can this 300 amp hour lithium battery be used in series to build a 48-volt system？
A:
Yes, Redodo 12V deep cycle lithium batteries can be connected in series to create a 48V battery system.
Note: Do not connect batteries with different chemistries in series or parallel.
Q: How many Redodo 12V 300Ah lithium ion batteries can I connect at most?
A:
The 12V series batteries support various configurations such as series, parallel, and series-parallel connections. You can connect up to four 12V 300Ah batteries in series, in parallel, or in a series-parallel configuration to achieve capacities of up to 40.96kW and energy storage of 61.44kWh.
Please ensure batteries are of the same model and have similar capacities for optimal performance.
Q: How do I store Redodo 12V 300Ah LiFePO4 battery?
A:
It is advisable to store Redodo LiFePO4 batteries at a 50% state of charge (SOC). If storing them for extended periods, it is recommended to cycle the batteries at least every 6 months. Recommended storage environment: 10℃～35℃ (50℉～95℉），45%RH～75％RH.
Q: Can I charge the 12V 300Ah lithium battery with solar panels?
A:
Yes, you can charge Redodo 300Ah LiFePO4 lithium batteries with solar panels. Here are 3 recommended ways to charge LiFePO4 lithium batteries.
1. Using Solar Panels
The Redodo 12V 300Ah lithium battery can be fully charged by in one day (with effective sunshine 4.5hrs/day) by 1200W solar panels. It may take more than one day to fully charge the battery by ≥1200W solar panels since the duration and intensity of light would be a great factor for their charging efficiency.
2. Generator/Alternator
If the alternator or generator supports DC output, a DC-to-DC charger is needed to connect the battery to the generator; if your alternator or generator supports AC output, please add a suitable battery charger to connect the battery and the generator according to our recommendations.
The Recommended Charging Voltage: 14.2V - 14.6V. The Recommended Charging Current: ① 60A (0.2C): the battery will be fully charged in around 5 hrs to 100% capacity; ② 150A (0.5C): the battery will be fully charged in around 2 hrs to around 97% capacity.
3. LiFePO4 Smart Chargers
To charge 12V 300Ah lithium battery, it is recommended to use 14.6V battery charger.
The Recommended Charging Voltage: 14.2V - 14.6V.
The Recommended Charging Current: ① 60A (0.2C): the battery will be fully charged in around 5 hrs to 100% capacity; ② 150A (0.5C): the battery will be fully charged in around 2 hrs to around 97% capacity.
We are full-time RVers that work remotely and we use a LOT of power with multiple computers, appliances, etc. Lead acid batteries never really could give us power for long enough or reliably enough when 120v landline power isn't available, but Redodo's lithium battery can keep us going for several days! With our solar array, we have been able to keep working seamlessly, switching from 120v to battery power without even noticing the change!
It’s working great! Running a 7cu 12v frig/freezer and Starlink in our 5th wheel in the deserts of Baja. No more worries about running low on my batteries. This replace 6 large AGM.
Customer Service has been awesome. I Ordered the Battery over the holidays and there was a shipping issue with UPS. Tina from customer Service was on top of it! She reached out to let me know what was happening and kept in touch to make sure I received the battery. I would recommend Redodo for any battery needs. I will be installing this unit into my RV and am already thinking a Second one might be need. Thank you Tina for your awesome support.
I purchased four of these batteries for my travel trailer. They are the greatest batteries I've ever seen. My name is Steve Weaver with Midstate in Prattville Alabama and I can't say enough about these great batteries. I wanted to be able to take my travel trailer to the desert and have enough power on hand to make it through the night. As it's turned out I can run everything in my camper including my air conditioning system all night long without having to save any power from worries of running low. 2,000 watts of solar along with these batteries and I will never have to plug into anything again. Thank you for the great quality in your batteries
Battery was extremely well packaged and topped off within a couple hours. I’m running it as an amateur radio back-up through a West Moutain Radio Epic-H PWRgate which floats it on a 12v power supply set to 14.5v. Hoping to add solar panels later.
Loving these 2- 300ah battery so far, had an issue with delivery on it and Redodo took care of it and sent another battery asap, thanks!
I would definitely buy from them again, pricing is great also!
Purchased for 4 ea. 300 amp hour batteries and have loved them every sense. I run my RV in the mountains using no gas operating my water heater refrigerator and air conditioner at nights. Couldn't ask for more.
I’ve been running the Redodo 12V 300Ah lithium battery on my boat, and I’m seriously impressed.
It powered my sound system full blast with heavy bass for 3 hours straight, and I couldn’t believe the voltage stayed at 12.7V for that long. This single battery replaced three 100-pound Interstate AGM batteries, saving a ton of weight while delivering even better performance.
If you’re wondering whether this battery can handle a real marine sound system, the answer is absolutely yes. It exceeded my expectations.
One recommendation: get at least a 40-amp charger. I use the 40A charger, and it brings the battery back to a full charge in about 5 hours.
If you’re on the fence, just buy it. You won’t regret it! 🔋🚤🎶
I had purchased 3 of the 300ah Redodo batteries and decided to buy a fourth before I installed them. I wired them in parallel to give me a total of 1200ah which will give me complete confidence of being able to be off grid and never need shore power. They seem very well made and are lightweight compared to the 200ah AGM battery I had previously. I will be using them hopefully for many years to come.
Here are the before and after shots. Photo one is ugliness, photo two is the way of beauty. Haven't got to run them through the paces yet but expect good things. The install was a breeze since my coach was already set up for LiFePo4 batteries to be installed. I've already recommended REDODO to others primarily because of the 5 star customer service I recieved during the purchase AND the install. I asked a question and sometimes within a couple hours I had an answer.
The batteries and the shunt monitor are working perfectly. We did an overnight test where it got down to 38 degrees F, inverter was on all night to use heating blanket and coffee pot, furnace at 65 F, 12 V fridge.
Confident we can last a few days of boon docking even if cloudy.
Belen was very helpful as I was working on the install and getting the monitor set up.
I have had an amazing experience working with Redodo products. My battery and inverter can power an air conditioner for hours with no issues. The image is my test - it is set up with solar panels, inverter, and all appropriate fuses and breakers.
I like to give a review after using a product for awhile. It's been almost a year and haven't encountered any negatives with our Redodo 300 Ah battery. The BMS has repeatedly done it job when it's supposed to. We did drain it by mistake down to 10.8V which the BMS shut the system down until our battery was recharged. There was no damage to our system or safeguards. Our battery came well packed, partially charged as stated and arrived within a week of us ordering it. My husband is so pleased with the performance that wants to order another as soon as the budget allows!
I have 4 200 plus amp HR batteries and 1 300amp HR REDODO batteries. The four 200 amp HR Batteries are to and my 10kw Sunpower hybrid inverter to run my RV. The 300 amp HR Battery operates my
Upgraded my 12v refrigerator. All the Batteries are operating as advertised. They work great and am very happy with both their cost and operation.
Great price on your batteries and fast shipping. Here's some pictures of the project we did with four solar panels on roof. 1440 watts, 24 volt system, 3000 W inverter, with solar built-in.
This is how I secured my battery in my CTC camper.i just returned from a ten week trip.i will going on another trip the last of August will the new battery.
I had to contact customer service to confirm the position I wanted to mount the battery bank was acceptable and they were very helpful to address the issue. While waiting for a response to this question I wanted to confirm the position of the cells so that the pressure relief vents were not placed upside down. I carefully opened up the battery case and was amazed by the build quality of this battery the bms had a substantial heat sink with heavy cooling fins something I have not seen on most batteries.
I installed this battery in our 2021 Geo Pro rv, with 300 watts of solar and all electric refrigerator. This battery along with solar allows us plenty of of power without the need to carry the generator anymore. This battery works as expected and advertised.
I have 8 of the 12v 100ah batteries powering my house and have not had an issue with them in two years so I bought the 12v 300ah for the camper. My camper setup is 800 watts of solar panels and a 40amp mppt all from Rich Solar which have been on there for 3 years. The reason I bought the 300ah battery is due to the 200amp bms. We camp in the winter and running the furnace and lights and water pump gets taxing on the batteries I had in there. The 200amp bms allows more amps to pass and allows everything to work flawlessly. Very happy with it!
So, I bought this 300Ah LiFePO4 battery from REDODO :
-First, their customer service (including Ms. Lilian) made sure the 70lb package got to my PO box.
-Then, I did a test charge-up/quick draindown >> good.
-re-charge-up, currently testing 72% complete slow draindown >> good so far. HAPPY SO FAR. Melton Apr 6
I ORDERED THIS 300 aH AND REALIZED I WOULD PREFERRED THE 320aH, SO I CHANGED THE ORDER, LOVE THE BLUETOOTH, AND HAVE YET TO GET OUT IN THE RV AND USE IT, VERY HAPPY WITH THE QUICK RESPONSE FROM THE COMPANY,AND FROM THE TECH DEPT, I HAD A QUESTION THAT GOT ANSWERED WITHIN HOURS. I ALSO HAD A MINER SHIPPING ISSUE AND THEY CREDITED ME $50 FOR MINOR INCONVENIENCE. ALL GOOD. WOULD USE AGAIN IF I EXPAND THE BATTERY BANK.
I have had batteries on shore power charge for 18 hours and I’m only at 66%. Is that normal?
I would’ve assumed after that many hours it would be fully charged.
I have purchased Redodo batteries before an they have performed at a high level. That is why I bought these larger batteries. Not fully deployed yet, however I expect fanomamal performance.
Thanks, Robert
