I have bought 4 of the regular size 12v 100ah blue tooth batteries of this brand. All I have done so far is to charge them, run a discharge and recharge them. I have gotten from 105.73 Ah to 110Ah. So far so good. I will be setting them up in 48v configuration once I get a 48v inverter. I plan on buying more in the near future once I get a few more solar panels to keep the system charged. I like them so far.
I have to say thank you for your very informative videos. I am just now getting into solar power and trying to learn about batteries. You have taught me so much. A little something in every video I have watched so far. You have answered questions I didn't even know I had til watching and learning. Thank you!
@@richmorpurgo5554 The more I learn about the life style of cruising the more I understand there are no easy answers. It's all hard work and sacrifice. It will take time but the acceptance issues will get solved. You can't say there are no problems with diesel.
"Nick & Raychel" youtube channel just did an interview with a couple that lives on a sailboat like you! Those people actually take customers out on 3 hours tours with their boat for part of the year.
Well Clark you're starting to get the Will Prowse effect. The price on this battery is now $359. Oh well I guess that's the price of success. I'm liking this battery or it's brother. Keep the good stuff coming.
Great videos guys! I'm retiring in 7 months and plan to make cruising my lifestyle. I hope to run into you two sometime. I'd love to buy you a meal and or maybe some beverages. Cheers!
Great video. When you do testing on the bigger batteries I would like to see how well they are built from a mechanical point. I think that is important factor when choosing a battery for a boat. I do not like batteries where cells are just held together with tape.
Hi Clark, perhaps a topic for a vid, however wondering if you've ever researched 24/7 power generation? Particular at anchor, our boats are either facing into; 1) Wind - suitable for aeromine technology, silent, less moving parts/maintenance, impact safer, could be horizontal low profile on roof, can extract heat from cabin (could be diy'd). 2) Oncoming Tide/flow - suitable for hydro turbine, i.e. Pelton wheel (imagine flow between cat hulls). 3) Swell - perhaps anchor to boat pull/slack Centrifuge. Also - were sitting on all that salt water, surely there's a way to produce something from that.
@@Clarks-Adventure Are you still using the huge wooden Wright brothers blade system? We were all 4>5 years younger then, incl tech. No improvements, hydro or other not beneficial? Or is solar enuf for the 2 of you?
@@Clarks-Adventure Thank you for responding. Considering going full electric, no fossils onboard (excl myself). Researching diy redundancies for gloomy periods.
I bought 4 of these minis. So far good. A couple of tidbits. Customer service through Amazons contact system has been great. I get a response within 12 hours and detailed. Also, the only thing i can do in the app is change the name for each battery. In the app I don’t get the graphs to show any data.
You should get graphs if you are using the same app I'm using. Buttons at the bottom. You need a different app to change parameters other than the battery names.
Great pup 'crown' looks like a little devil kid toon. As I suspected, though some battery manufacturers are buying cases. 180+AH appears to be my better choice.
On your leaderboard in the "Notes from Clark" column for the Redodo 200 Ah Plus you state: "If you are going to buy a bunch of Ah it's best to have it in the form of larger batteries. Getting more under each BMS has advantages". Really good info to know, I was heading down the path of two banks of 3 or 4, 100 ah batteries. Right now on Amazon I could get 6 100 Ah Redwoods for under $1800. Where the 300 Ah Redodo is $1100. So I was considering the cheaper option of course. However, your information that there are advantages to the "under one roof BMS" changes my value calculation...as does the additional cost of 2/0 cabling and battery lugs to build each bank of 3 or 4, 100 Ah batteries. Copper is NOT cheap these days and it takes time to make those cables. Additionally each one of those lugs is a weak point, fraught w/ the risk of a bad crimp, corrosion, etc. It is interesting to see how the different models of the same brand can diverge so much in quality/performance. There is a small difference between the 100 and 200 Ah Redodo (200 Ah cells are only a good for instance). Wondering about any possible differences in the 300 Ah version. Curious, what's better "Great" or "Excellent"? I assume Great is better because you made it bright green but thought I would ask. Awesome video series and tests. Try not to burn down your boat though😉.
After I answered your comment I will start filming on a 300ah power queen. Very similar to the Redodo. So Saturday I'll likely have a lot to say about larger batteries. Everything you bring up is correct. Look below the leader board. There is a key to the relative order of my words.
Thank you for taking the time to share the video. I’ve been waiting for it to come out. The dimension sheet on this one and the elefast battery are different measurements. Can you provide true measurements of the battery? I’m debating between the elefast and re-dodo, but would prefer the prismatic cells and cold temp shut off if it is the correct size. Thanks!
@@Clarks-Adventure Perhaps update the dimensions on your spreadsheet. I almost dismissed the Elefast and this one because the sheet says the length is 12 inches. Thanks for the videos, BTW. They are proving very helpful to inform my buying decision.
Question for you. I plan to use this battery as a backup system for an aquarium pump such that if/when the power goes off, the battery backup will kick in. I want to know if I can keep it on a trickle charger while it is connected to the pump that way it will always be fully charge or will i have to top it off manually every so often? ie, i am not sure how long it will stay fully charge if not being used. Many thanks. Milton
Good question. Li is touchy about this stuff I built a thing called a BankManager that takes care of li bank but for an aquarium it would be ridiculously expensive. So not the perfect answer and your battery won't be treated perfectly but I'd float it at 13.3v. (definitely below 13.48v). And charge it to 13.8v then stop only after it gets used like in a power outage.
Hello Clark great videos quick question is saw the video on putting lithium batteries in parallel. I bought the elefast mini, I saw the pupvmhab considering that this is or might be the same manufacturer/ battery, is it possible to parallel elefast and pupvmhab 12v 100ah without habing any issues. Thank Clark and Emily keep videos coming.
Hi, I was wondering if you have a good reference for Moseworth batteries? Supposedly they are from the same people of Flypower. The 100ah lifepo4 model on Ebay (USA) are in 175$ with free shipping. I am undecided between the Moseworth and the EcoWorthy also 100ah which cost about 190$. Which one would you recommend?
I have no experience with those but look at the "leaderboard" linked in the description. The prices are old but it's a list of the batteries I've reviewed. This video was my worst review. Take a look at my other reviews, there are things to be learned about LiFePO4 in general.
In the product description it says only 4 batteries can be connected in series or in parallel? Why is this? Why could I not connect 6 in series for 72v in order to run a high performance golf cart?
Watch my other videos and check out the batteries on my leader board (in the description). In short it will put power in the battery but charging Li for long life is tricky
Where can we buy your Battery management system ? you should put a link in the video description Thanks PS : all your links in the video description are pointing to nowhere ( amazon, emily link, speadsheet doc, etc ..) you are an amazing technician but real bad for business
There is a link to it in the description of all our battery reviews. docs.google.com/spreadsheets/u/0/d/1dyJf7SuYQFxorzdIANKgf7Qk3hviZYzSHoNdjxqUKeM/htmlview Click it. You will see.
Love your content and don't want to be that guy but you have an "A" in the model number that is not on the battery..... just trying to save search time when people go looking to buy....
Seawater is less conductive than you probably think. So likely it would just discharge over a day or so. But if shorted by a copper bar it would shut down in a few seconds. That's one of the jobs of a BMS
That's more a think of the other li-ion variants. LiFePO4 is hard to get into thermal run-away. That's why we use only this on boats. I don't want my big decision some day to be "do I drown or do I burn".
@@Clarks-Adventure I was wondering how I was going to build a fireproof enclosure for them on my Catalina 27 with its very limited space. I'm working on setting it up to do a passage next year.
@EmilyAndClark , no worries, as you made me aware of the dangers of hacking the battery Bluetooth, more important to protect me from that evil...now I will be sure to avoid that feature, until there is a way to secure from hackers....very grateful!
These cheap batteries with passive balance are awful. So much better to have a BMS with active balance that uses 2A taken from the high voltage cell and pushed to the cell with the lowest voltage. Balancing concerns like those in this video are a thing of the past
@EmilyAndClark have you tested to see if a $5 active balancer actually works? I am much happier to use a JK BMS 200A with a built-in active balancer. $100 For the money, this isn't a better one on the market, yet
Yes I have one a test and I read the datasheet on the chip it's based on. I use the one that doesn't have a bunch of capacitors on the board I'll do a video sometime. No reason you can't run in parallel with the BMS of your choice.
You need to register your trademark to sell on Amazon. Those are easy to be unique and since their brand is based on being the cheapest there is no need to be memorable.
Information overload. All this data we can get with kit, what use is it? If you have the learning it may be of use. As an example, Food packaging labeling (in the UK). Only about 1 in 10 actually read the data. Of those only about 1 in 10 understand it and only about 10% use that to make a choice. So, all that info for 0.1% of users.
