I bought my first battery using your discount code and not even 2 weeks later found the exact same battery on Amazon for $649.99, so I bought a second battery. I have them connected in parallel using a 24” 0/1 cable, I am using a Renogy rego 60 amp charger set at 20 amp. By default Most of my accessories are connected to my starting batteries except my 12 volt cooler, which I wired directly to the redodo battery bank . The rego has a reverse charge feature and does very well keeping the starting batteries above 12.4 volt 12.4-12.7 and although convenient, I feel that the price I paid for the charger was a bit extreme. By the way, I am an over the road truck driver in a 2019 freightliner cascadia. I also have 2-175 watt panels on the roof of the truck. I did all of this to save a little fuel on down time. I honestly believe I will receive a return on the investment in just a couple of years of using the set up.
I have two of them!!!! During the entire process in building my sytem, Lillian(Staff at Redodo) guide me step by step. I haven't had any issues at all with this batteries, the best customer service!!!
I purchased 4 of these for my RV in a series/parallel 24v to my Victron Multiplus II. I asked for best connection config chart that they sent to me immediately. I absolutely love these batteries!
I bought this battery 2 months ago on Amazon. Very happy with my purchase. It’s worked perfectly for my off grid cabin. Microwave, fridge, etc…no problems!
Yay, the professor likes my battery. I have this one in my preparedness setup and was impressed with its specs and the way it tests for me. Thanks for the good review.
I think it's safe to say nobody provides more "Data" in their videos than you do...do. That's a heckuva deal. Just a couple years ago it was common to pay that much for a 100AH, 12.8v, LiFePO4 battery, so the per watt-hour price has dropped by almost 50%.
Man,thanks for saying the doodoo doesn't need any special equipment, I've been hesitant to change from my x4 golf cart batts because i dont want to rebuild my entire system.. 🤘.. definitely going to order a couple
Professor: Your product reviews are always informative and entertaining! The videos are morphing into MCU movies, where you “have-to watch” the pre-end credit scenes to drop down laughing.
Hobotech Thanks again for a great video and all your advice👍 Can we hook one of these up to the 12 volt battery charging cable for the Bluetti AC200???… I remember it said for 12volt lead acid batteries.
I bought same battery on amazon last year,its jumped in price but i use it every day with a solar system to run 12 volt lights and fans but also a 2k inverter.
Red Odo (colorful Star Trek) character is how I've been pronouncing it. I've been looking at this one. Love that 200 Amp charge/discharge rate. Just wish it had low temp disconnect.
Love your channel. These look really good I'm looking to getting a wind and solar set up for my house because of electric and gas keep going up and possible roaming black outs, etc. I was looking at your website, but everything is more geared to RV life, camping, and portable generators, etc. Have you considered expanding to whole house type systems? I've been looking at a few at the "Missouri Wind and Solar" who also have a UA-cam channel and decent hybrid systems around $3,000 depending on the customization. I would love to see you review some of their hybrid systems and recommendations for compatible charge controllers (ones in the combo kit are not compatible with lithium batteries). I truly respect your opinion due to your diligent testing of products. Also, do you know how long your code will be active? They have free shipping available until October 28th (still have to pay tax) and would like to get a couple, but still figuring out which controller to use.
Hey Tom, as per the drop in argument. How are the cells going to balance with a standard LA converter/charger on the RV? What about the alternator issues- low idle overheat, long duration overheat, fly back spikes etc? Every test I do shows 80% SOC is the realistic max. The remaining 20% takes days with the standard WFCO. Although I loved your use of the word flotsam, I’m baffled that you would recommend drop in without at least using a DCDC on alternator.
Excellent review of a smoking deal on LiFePo4 tech battery, probably the best deal out there, except the name of the company is Redodo-nculous. If BattleBorn doesn't lower their prices it'll be the downfall for their company. Anyone who has enough knowledge to put together a small off-grid system would be foolish to hesitate harvesting solar energy to run your own system! PG&E (Northern California) racketeers have been taking people to the cleaners this summer in their outlandish pricing, absolutely nuts. Thanks for posting!
My experiments with the Redodo, the same one, didn't even nearly jive with your data...until I put the battery on that revolving device and spun it a few times.
Dear Professor. I wish you did the "Professor Hobo Monthly Disaster Prep" From the systems we last reviewed these are my picks for. 1. Basic electricity during power shutdown to keep your refrigerator and cable router running with these solar panels. 2. This is higher kw hr to run your washer and 240. W these panels. Here are the affiliate links. Here are the installation videos. I love your tests but I wish I could see all the results in a table to make those cost comparisons and features in one place.
Thank you. I'm not seeing where you're testing the low temperature cut off, or did I miss where you already know it doesn't have one? Or maybe it has heaters? Do you ever test low temp cut off, by placing in a freezer or disassembly? It's a critical factor. Thank you! 🙏🏽✌🏽
They are quite similarly sized, but they do not use the same case, and the 410Ah is both taller and wider. The 200Ah model dimensions are 20.5 x 9.37 x 8.54 inches (1,640.4 cubic inches), and the 410Ah model dimensions are 20.47 x 10.59 x 8.66 inches (1,877.3 cubic inches).
Send that battery to Will if you don't want to do a teardown. I like to know what corners might be cut inside. SOUNDS like a great battery, but has Redodo been around long enough to make it likely they'll still be here to honor that warranty? Does it require shipping back to China?
I cant really tell how far away your IR thermometer is from the battery but for anyone using them, it is important to know that these contactless thermometers are not lasers, they take in thermal information from their cone of vision, and then average it, which means if you are 5 feet away from something, like a sparkler at over 1000F, but the background is 30F, the thermometer is probably going to read somewhere around 35-50F What annoys me is that this information is usually not on the device and only in the manual, who keeps/knows where that is when you're trying to stay as far away as possible from something that could be dangerous to be next to. My rule of thumb is to hold it an inch or 2 away from whatever i am trying to measure, and if it is reflective, first place a layer of black electrical tape over it for a minute or 2 as the thermometer tends to only measure the reflections
Wow this is awesome, I have a question? I have a Winnebago Era with the 2500 propane generator, will this be ok to start that as I don’t believe the cold cranking amps are very much , but not sure , thanks Professor let me know so I can order one through you
I have started my Onan 2800 generator using 3x Battleborns and never had an issue. I don't think starting a small generator with this would be a problem.
What is the self discharge rate with BMS on but no load? If an Rv was left parked long enough with the battery connected wouldn’t the BMS eventually completely discharge the battery to the point where it wouldn’t reboot?
Alternators don't push more amps than they are capable of. If the battery can take a 100 amp charge and your alternator puts out a max of 80, then the battery will only charge at 80 amps. Alternators are made to handle high amperage charging as long as they have enough speed to keep cool.
If I well understand... I do not need to change the converter of my RV to recharge this lithium battery? I thought a special converter was needed for lithium battery?
I messed up and did not notice I bought 2 batteries 1 is 12v the other 12.8v can I still run them both together or do I need to exchange 1 so they both match?
HI, question, is there a way to use this or any other battery (other than the official Ecoflow batteries) with a Delta Pro unit, I recently bought one and I would like to expand its capacity but looking for alternatives, if possible. Thanks in advance!!
I'm planning on using similar batteries with a Bluetti, just charge from the AC ports, and recharge by plugging the AC adapter into a seperate inverter. You lose some power both ways through the conversion, but you save a hell of a lot of money!
In addition to using a full-on AC inverter (which has efficiency losses on both ends) you can simply use a boost converter to get whatever voltage the EF Delta Pro wants to see. It's not rocket science, but you do need to know what you're doing.
Some people use a capacitor product on their battery to supply big amps. For their 1000w stereo systems so the lights don't dim every beat the woofer pumps out. It also keeps the spark plugs supplied with power for harder acceleration (not a diesel concern), and maybe most usefully, starting in the freezing cold. Aliexpress has some of these, they are up to several hundred dollars. Save weight on the boat. You might also use a small car booster pack.
would this battery work with a 2000 watt invertor? Enough to power the micro wave on my RV.???? How many amps can you get out of this battery with the proper inverter ?
QUESTIONS: Do cables from a bank of batteries leading to one inverter have to be the same length? Cables leading to two or more inverters? From solar panels to batteries? Does it matter if the batteries are AGM or Lithium? Thanks so much if you answer. Might make a good video. If you've already done one on this topic, would you please leave a link? I searched your channel with "cable length", but didn't see exactly what I was looking for. Thanks!
Cable lengths being equal should not matter. The wire gauge needs to be sufficient for the both the load and distance times two between batteries and other sources and loads, like chargers, inverters, and solar panels. Consult an ampacity wire chart
I was wondering if you can test the RV 12 volt refrigerator with the compressor well I was wanting to get a 12 volt refrigerator freezer for my motorhome that goes in the place of the propane 110 refrigerator
Its pronounced (Red-odo) now you have to Re -doo doo the whole video jk lol - Strange name for a battery the price is very good though I've seen 100ah batteries for the same price
The good thing about this battery is it's "Younger, Bolder, Stronger" unlike those old timey baby boomer LiFePo4 batteries. Damn dirty hippies! Cut your hair and get a job!
for 700$ you can make a 560Ah lipo4 battery with a 250A bms. made from new good cells with searchable qr codes and good support from the seller,,remember to do a tiny bit of homework and find the good seller ,
if you want to build a bigger battery system do NOT buy these and mount them in both series and parallel connection ,series for 24v can work but ppl are building massive 48v systems with 12v batteries ,,,parallel connection in order to increase the amount of avalible ah is ok we are starting to see problems with overcharge in these types of setups after a certain amount of time the bms have problems keeping the voltages down in some of the batteries resulting in melting of plastcases and such we see voltages as high as 17v in 12v batteries ... in my opion the best solution for a bigger battery bank is to buy(from a good seller) the 280ah or 304ah cells and build your battery to spec and mount a very good bms you will get double the power for the same prize, it is very easy and battery cases can be purchased fairly cheap to, and if one wants to buy these premade batteries find the ones that fits your system voltage and just do parallel connection

Overpriced box store trash
Red - Odo (not the shape shifter)
The lack of low-temperature protection on such an expensive battery is kind of ridiculous.
Most of these cheaper batteries lack low temp protection.
What is the self discharge rate with BMS on but no load? If an Rv was left parked long enough with the battery connected wouldn’t the BMS eventually completely discharge the battery to the point where it wouldn’t reboot?
So running over the amp capacity of your RV alternator isn't an issue with charging?
Alternators don't push more amps than they are capable of.
If the battery can take a 100 amp charge and your alternator puts out a max of 80, then the battery will only charge at 80 amps.
Alternators are made to handle high amperage charging as long as they have enough speed to keep cool.
If I well understand... I do not need to change the converter of my RV to recharge this lithium battery? I thought a special converter was needed for lithium battery?
Nope. As long as it charges at least 14.4v you don't need anything special.
No one is talking about the music........the price is right.
Even 12v Gel Battery can wake it up if the BMS has shut down?
Interesting battery. However the Neg bus leads are soldered to the BMS. A potential Red Flag in high current conditions...
