BACKGROUND:
I've developed a device that helps you add LiFePO4 batteries to your power system.
(www.emilyandclarksadventure.c...) Since I started selling them, I can't count how many people have asked me my opinion on what would be a good battery to buy. This series is my mission to find you the best, cheapest LiFePO4 battery out there right now.
THE BATTERY LEADERBOARD: Take a look at this link. It leads to a table of all the batteries we have reviewed, looking for that diamond in the rough. We'll keep adding to it.

Continuation of a very great series. Looking forward to the "build" episode. Thanks guys.

[@wendellhammond7853]

always good info. I bought this brand and love them.

You're very welcome, Reggie

[@vonfleming2178]

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!

[@EmilyAndClark]

Nice of you to say.

Clark doing a raw cell DIY build. I'm in for watching that. I have a feeling I can predict how Temptress will be powered in the future. We will see.😊

[@richmorpurgo5554]

Nah, cruising doesn’t lend itself to electric.

[@nodogrunner]

@@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.

daysailing from a dock with power DOES lend itself to electric though!

[@NerdThingsAndMore]

Thanks for the info and video.

[@a2022z2]

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.

Awesome!

[@hectorquintanilla5520]

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.

[@EmilyAndClark]

Yes for those obvious exact copies you'd be good. The only difference is the label.

[@robl6823]

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!

[@EmilyAndClark]

10.125x6.75x8.75. With a ruler

[@robl6823]

Thank you so much!! I was hoping it would fit in my group 24 boxes.

[@KennethEverett_N]

@@EmilyAndClark 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.

[@EmilyAndClark]

Done. Thanks

[@johnnylightning1491]

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.

[@EmilyAndClark]

Yes the other one sold out in two days but they kept the price the same. Vote with your wallet!

[@Despiser25]

8 mo later they are for sale at $179. (209 on sale -30) The normal size one costs $149. Amazing how cheap they are getting.

[@andrewkerr659]

Could you address whether the batteries are ABYC E-13 compliment?

[@braithmiller]

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.

[@EmilyAndClark]

Next review is a 300ah power queen

[@Lana_Warwick]

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.

[@EmilyAndClark]

I have videos on building your own wind generator

[@Lana_Warwick]

@@EmilyAndClark 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?

[@EmilyAndClark]

Solar is enough. And the rest of it isn't real. Things of writers that saw a picture of something and made up the rest

[@Lana_Warwick]

​@@EmilyAndClark 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.

[@EmilyAndClark]

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.

[@acampbell198]

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😉.

[@EmilyAndClark]

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.

[@josevelaz9385]

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?

[@EmilyAndClark]

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.

[@josevelaz9385]

Thank you for your help 👍🏼

[@redwood1957]

I'm laughing you look in the locker then jump. Im saying is nutty professor or Doc the correct name. Thanks

[@brianmiley2109]

Is there a way to turn the Bluetooth off for off season storage? If not does it draw enough to run down a battery during 6-8 months of storage?

[@EmilyAndClark]

I bet it doesn't draw a lot.

[@WilliamAArnett]

Is it OK to charge a LiFePO4 battery at zero Celsius if the charge current is very low?

[@EmilyAndClark]

Nope.

[@donniefoster7713]

So if I buy this battery is it gonna be ok if I buy a 10amp 14.6 volt charger to charge the battery? Km gonna use it for a trolling battery

[@EmilyAndClark]

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

[@richardriehle4159]

does the bluetooth app work on chromebooks ?

[@EmilyAndClark]

I don't know? Do apps usually work on Chromebooks

[@clarklove72]

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?

[@EmilyAndClark]

BMS isn't up to what would happen when one shuts down

[@clarklove72]

Ahh. Too bad there’s not some middleware that would allow the BMS’s to communicate with one another.

[@EmilyAndClark]

It won't help you but to put more in parallel you can use multiple BankManagers You should use 24v or 48v batteries

[@johnq.public2621]

I'd be curious where all these battery manufacturers are getting their supplies/components from? 🤪

[@EmilyAndClark]

Well China of course. I don't think I understand your question.

What would these batteries do if shorted out by a flood of seawater?

[@EmilyAndClark]

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

[@thisoldboat7393]

@@EmilyAndClark I've heard how they can flare up and be not very nice.

[@EmilyAndClark]

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".

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]

I agree. I'll be putting active balance in the one I build from cells.

[@herkko61]

Thanks for this hint. It's good to know about better technology in balancing the cells.

[@EmilyAndClark]

And active balancers can be bought on eBay for like 5 bucks

[@timevans8223]

@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

[@EmilyAndClark]

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.

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.
