Redodo Lithium? October 17, 2025, 07:12:27 pm Anyone have any experience or opinion on the Redodo brand of lithium batteries? Yeah, I’m still looking for the perfect replacement… I was ready to pull the trigger on Ron’s recommendation for the SOK Battery 12V 206Ah LiFePO4 when I stumbled on this Redodo. . Seems like a decent alternative for a lot less. Thoughts?
Re: Redodo Lithium? Reply #1 – October 17, 2025, 07:55:35 pm Another lithium battery without any information as to its specifications. I seriously doubt anyone here will provide insight.The battery appears to be too long to fit in the existing battery compartment. It's pay your money now and take your chances.For several years, I have been following Will Prowse's YouTube videos where he tests and then tears down various lithium batteries, examining how they are constructed and the characteristics of the BMS. I suggest looking at his lithium battery videos before buying any unknown brand.https://www.youtube.com/c/WillProwse/videos.Larry
Re: Redodo Lithium? Reply #2 – October 17, 2025, 10:21:38 pm Yup, I’ve seen his videos. Good stuff. Let’s see if he did Redodos. He did like the SOk for sure.
Re: Redodo Lithium? Reply #3 – October 17, 2025, 10:44:35 pm A little follow up; here is his link with his recommendations: mobile-solarpower.com.Currently this is his top recommendation: Eco-worthy 12.8V 280Ah. Any opinion on starting with one of these? Do you see any installation red flags? 2 Likes As an Amazon Associate Lazy Daze Owners' Group earns from qualifying purchases.
Re: Redodo Lithium? Reply #4 – October 18, 2025, 12:09:11 am Hi Remicks. The Redodo at $350 is a good price. No blue tooth. I'm not sure that matters too much if you have an alternate battery monitor system. I don't remember the size of my battery box. Many here take out the box. At 21" long, the Ecoworthy may not fit inside the box. I don’t think you could get two of them inside the battery box as is. RonB edited: I looked up my battery box dimensions. I suspect that LD used the same boxes for all newer than about 1996. It is 17- 3/4" wide inside. (18" outside width), 13- 3/4" inside (14" outside), 11- 3/4" deep (12.0" outside) Measurements with roll out tray removed. I had to destroy the tray to get it out, and I installed a new floor inside the box to get a flat load bearing base plate for the new batteries. The Ecoworthy is 17.83" long. About .08" too long to fit sideways. And you could only fit one in the box. EW=9.37" wide, 8.7" tall. RB
Re: Redodo Lithium? Reply #5 – October 18, 2025, 01:57:41 am The ECO-WORTHY 3584Wh 12V 280Ah battery would be my choice. It has Bluetooth, a low-temperature sensor and more capacity. You live in a cold weather climate, the low-temp sensor prevents the battery from damage in below freezing weather. A good thing.If Will liked the ECO-WORTHY, it’s probably a decent battery. The battery may not fit in the battery box, but should fit under the refrigerator. The battery box can be repurposed for an inverter and/or other devices. The plastic battery box can be removed for even more batteries.These are strange times, the number of lithium battery brands and the continuous dropping of prices are hard to keep track of, difficult to understand how the prices keep dropping during times of high tariffs. Take advantage of it.Larry

And you could only fit one in the box."That may or may not be a significant drawback, depending upon how much of an upgrade you're looking to make from your lead acid batteries. The Trojan batteries that Lazy Daze installed had 225 amp-hours rated capacity when new, which means about 110 Ah usable capacity. The Eco-worthy 280 Ah battery, because it's a LiFePO4 battery, has about 250 Ah usable capacity. That's more than twice the capacity of the Trojan batteries when they were new.So does it matter if you can only fit one Eco-worthy battery in your battery box? Only if doubling your capacity isn't enough.
Re: Redodo Lithium? Reply #7 – October 18, 2025, 11:56:50 pm Thanks Andy and Larry and Ron! Everyone has been instrumental in helping me thru this and giving me the confidence to move forward.Well I went ahead and ordered the eco-worthy and cleaned the existing battery box to the shell. I think (hope) I should be able to fit it. I’m only looking to add the one battery right now. I have a Blue Sky 3000i coming in too. I think thats all I need to get it all installed. I’ll probably upgrade the solar panel next Spring to improve efficiencies and really take advantage of the new battery. I’m not too concerned with the install but do have a couple of final questions (famous last words).- I hear mumbling about straining the truck alternator with Lithium. Frankly I just don’t understand enough to wrap my head around it. I’m hoping that this 12v install won’t endanger the alternator.- how do you guys deal with storage of the lithium batteries. When i close the rig for the winter i usually removed the old wet batteries. I store the rig under a cover, off site, so the solar is no longer charging. Is it a problem to leave the lithium in the rig over the winter (in NJ).- finally if/when i upgrade my inverter (i still have the Powerstar UPG400) would it be possible to run the microwave or outlets? Does that just “happen” with more wattage or is there more to it?Again, thanks for the help. I’ll let you know how I make out when everything comes in and is installed.-Chris
Re: Redodo Lithium? Reply #8 – October 19, 2025, 12:35:13 pm Hi Chris; Lithium batteries have a water based electrolyte, and freezing will ruin them completely. (a lead acid battery has acid inside when charged, but discharged also contains mostly water, and will also freeze). You will have to remove the LiF battery during freezing weather and store it in a heated place. Some storage areas may provide electricity, and a heater can be left running inside, but in the vented battery box, exposure would still kill the battery.While this battery will shut off in low temperatures, there is no internal heater. These internal heaters are for overnight events, and use battery power to run the heater. Unless charged enough during the day (above freezing) to compensate for power used at night, it would still run out of power, and freeze anyway. I should have mentioned this earlier, Ecoworthy does have a metal cased version at $250 for a 150AH battery. Two of these will easily fit in your battery box side by side, and give you 300AH capacity. It looks like they were designed to be on end; the terminals and a pressure relief valve are on one end. Although more than the single battery price, for two you still get bluetooth and an extra 20AH. But no heater. Also easier to handle just one battery at a time, (41#) instead of the one huge 280 AH battery. (63#) Both of these 150 AH batteries still cost less than the $585 single 206 AH S.O.K. battery. Amazon.com: ECO-WORTHY 12V 150Ah Metal Shell LiFePO4 Lithium Battery with... Hooking up two batteries in parallel is really simple, but doubles how much power is available for high power loads like an inverter capable of running a microwave. (short duration use). Something like a roof air conditioner would be better served by a battery bank in the 600+ AH range and 500+ watt solar capability. Two years ago (time flies) when I got my SOK's, they didn't have internal heaters or bluetooth, ($1029 each!), I bought a 12v heater blanket for both. Meant for fresh water tanks, it works, but I have to be there to turn the heater on, and ensure there is enough power to keep them warm for extended protection from freezing. In your off-site storage, is there power available to keep the motorhome and batteries warm? RonB edit: I forgot to address the alternator issue. With the 2001 MB you have a diode isolator. That will protect the alternator enough. RB As an Amazon Associate Lazy Daze Owners' Group earns from qualifying purchases.

Does that just “happen” with more wattage or is there more to it?Our 2003 LD, with lithium batteries, has used the alternator and stock diode isolator to charge the battery for three years without problems. I purposely left the wiring from the isolator to limit the amperage flow, instead of upsizing it to get the maximum amount of power from the alternator. Modern automotive alternators are self-limiting; as they get hot, the output drops, preventing burnout. While alternators wear out, I can not remember anyone on the Forum reporting an alternator burnout. Our Factory alternator's brushes wore out at about 140,000 miles and started charging intermittently. Its location simplifies the replacement.Ron is right, removing the battery during winter weather is necessary since you park it remotely and do not heat it.You already remove the wet batteries, so it isn't a new task. The good news lithium batteries are light, weighing about half as much as a wet cell battery of the same size.A 280 or 300 amp/hour battery pack can run a large inverter and your microwave. Some inverters are standalone, others are wired so that the various outlets in the MH are powered. The standalone variety of inverter has somewhat simple wiring; the whole-house powered models are much more involved and costly.Larry 1 Likes
Re: Redodo Lithium? Reply #10 – October 19, 2025, 01:43:13 pm Larry got that right about a stand alone inverter being easier to connect and run. I've been happy with my simple one. It was also small enough to fit through a drawer (removed) hole to fit in a 'nook' of my cabinetry. The provided power cables were underwhelming!

Re: Redodo Lithium? Reply #11 – October 19, 2025, 05:19:33 pm Thanks for the clarity guys. I’ll build this out for easy battery removal.As I mentioned, my house inverter is the Powerstar UPG400. The wiring going into that is not simple. I thought the next step was to replace it. Am I understanding you guys right in that I leave the Powerstar as is but add a stand alone, more powerful inverter like the Novopal? I’m not clear on how you’d wire this to supply it to the microwave or the house outlets other than running extension cords to the inverter’s plugs. What am I missing?Also, having 2 inverters running off the batteries isnt a problem?
Re: Redodo Lithium? Reply #12 – October 19, 2025, 05:43:03 pm Two inverters can run off one battery.The Powerstar is for the 120-volt TV. Leave it alone unless it is burned out. Iti a 400-watt inverter, much too small for a microwave. You will need a 2000-watt inverter for the microwave.With a standalone inverter, extension cords are used. A whole-house inverter is a much more complicated installation.

Re: Redodo Lithium? Reply #14 – October 19, 2025, 05:56:47 pm @Steve, I’m hoping it wont be an issue to just pull the battery. We’ll see when that monster is delivered. @Ron, ok, I get it regarding the second inverter. I ripped out the TV and the awkward shelving already. We dont want the entertainment center installed. If I’m dying for entertainment, I just stream through Starlink on my ipad. I may get a portable TV at some point but thus far we havent missed the TV. I could see using the extra inverter for an electric heater or making coffee or something.
Re: Redodo Lithium? Reply #15 – October 20, 2025, 01:03:27 am Steve, I'm with you. I have never heard of lithium batteries freezing. My plan was to leave them on the trailer for the winter, which can have an occasional freeze. RONB Please tell us where you learned about this problem.
Re: Redodo Lithium? Reply #16 – October 20, 2025, 03:15:34 am Hi Rich, It was a while back (2-3) years ago, on the internet. I'll see if I can find that mention. And of course the problem may have improved in the meantime. RonB

If there is any published info to the contrary, I would like to read it.It looks like very cold conditions may be damaging to lithium batteries if not heated. From the Renogy webpage.Will Lithium Batteries Freeze? Cold Weather Impact Explained | Renogy US"Can lithium batteries be damaged by freezing temperatures?Yes, freezing temperatures can damage lithium batteries. When you expose a lithium battery to an extremely cold environment, the electrolyte can freeze, resulting in a badly damaged internal structure. The damage can be in terms of reduced performance and battery capacity reduction. In the worst cases, it may also cause complete failure."Battleborn recommends not storing their lithium batteries in sub-freezing conditions..Will Lithium Batteries Freeze? | Battle Born Batteries"For those who will not be using their batteries when the temperatures drop below freezing, it’s generally best practice to disconnect them for storage. With Battle Born Batteries in particular, we recommend beginning by bringing them to a full state of charge. Then disconnect them completely and ensure they are stored somewhere temperatures will stay above -15°F. Storing your batteries in subzero weather (-15°F or lower) has the potential to crack the ABS plastic."Larry
Re: Redodo Lithium? Reply #18 – October 22, 2025, 11:33:19 am Hi Rich; manufacturers have resorted to putting 'antifreeze compounds' in with the electrolyte to extend the temperatures downward and upward. This makes them more survivable in hot and cold environments. It does increase the complexity and weight, (cost), and doesn't extend it very far. -15F for instance. Now that is really cold for around these parts, but of course the RV is meant to go other places, and be a survival (more comfortable anyway) option. RonB
Re: Redodo Lithium? Reply #19 – October 22, 2025, 02:17:07 pm I know you’ve been dying to hear my progress. Ok, maybe not, but I’ll share anyway. Lol, the battery doesn’t fit. You warned me. It was ever so close but not worth cutting into the box lip. So it’s going in the cabinet under the fridge and we’ll use the now empty battery box for external storage. It’ll be easier to remove anyway so I’m looking at it as a win-win. Plus some room for expansion or the extra inverter or another battery. We didn’t really use that space for much anyway…One quick question: I’m installing the 3000i, and there are thick solar wires and battery wires. Easy to identify. But there are also a pair of thin wires there too. Any idea what they go to?
