Lithium badly needs a good active balancer. Passive balancers are just useless and will invite problems sooner or later.

Sir are you currently (or in the past) a pastor or some high ranking church figure ? You definitely sound like one.

What would the minimum ah of the 12v battery have to be to charge a laptop with this device?

i want one, but a bit pricey for me. Filling in the survey. I have all the fridge skills and equipment.

Why don’t they have balance leads like my lipo batteries for my rc cars. Or is that pretty much what a bms built in the battery does ?

That is awesome that you figured this all out. Good job buddy

Maybe just not use these firebombs in the first place. I plan to live without them as I have for the past 20 years.

25:17 there are, aside from specific external parts you can purchase separately to include a BMS, or balance board etc. I build my own batteries from fresh cells. Most hobby chargers will charge that way (at least if you are using 12 to 24 volts), I have as ISDT Q8 max, that has balance connection along with "main" power connection, and it ensures each cell is balanced the same so you get the most out of your battery as a whole. It dynamically adjust the charging based on the cells like you stated.

I also bought 2 of these after watching this video. One seems to be decent ( so far) but, the other one is hot garbage. After only a few cycles the cells were so out of balance I had to open the unit up to try and balance them manually. These are the voltage readings I got - Cell 1 - 3.332 volts, Cell 2 - 3.009 volts, Cell 3 - 2.882 Volts and Cell 4 - 2.849 Volts. How does anything get that bad out of balance with less than 8 cycles? Also my BMS is different from yours, it only had one temp sensor instead of two and it was rolled up and glued to the BMS insulation board instead of attached to the cells like it should be. Looks like I got the Chinese bait and switch they are famous for, get a couple of good reviews then change the materials list and start pumping out the cheap garbage hoping no one catches on. On the other hand, all of my Redodo batteries work great - Note: I was using Victron chargers so it wasn't a crappy $40 charger that messed the Elefast up, this battery was junk when it left the factory. Oh, I do love all of your videos Clark so keep up the good work!

Hey Clark I have a 3 power queen 200ah 12v batteries I noticed that one of them has a rattle when I shake it. Wondering what your thoughts are and what I should do Thanks for the help

18:48 whatever you're saying since last 7 minutes can be done with any good bms. Just have the settings (high cut, low cut) same among all parallel batteries. It works.

Wonderful product. Sadly it costs more than my entire bank. 😅

Unfortunately, there's a high number of wrong information in this video. Oh, this was a product presentation... now it makes sense.

I want one in a box however I live in Qld Australia can you post here Brisbane cheers Steve

October 2024 here, you should’ve waited. Bought 2 100ah for $250 yesterday.

Brilliant talk about lifepo4 battery But does this go for DIY packs of cells. IV just got a 48v server rack"new" with eve 280ah cells, IV broke it down to make 2 24v packs.... I'm currently top balance all cells (8 at a time). But IV just had a customer ask me to look at his server rack....goes from 100% to 20% in about a hour...,.... Same again.....cells not balanced so BMS was seeing one cell hitting full and stopped charging then saw another hit low so shut down ....... Now all fully balanced.....works perfect.

Memory effect in lfp works differently. What you explained is different kind of memory effect observed in other cells

Not sure I'd want to charge a lithium battery with the only current limiting being whatever size fuse you use and the only voltage limiting being a voltage sensing relay. Seems like a dc to dc charger would be far safer and prolong the life of the battery. But some voltage and current protection is better than none.

I have abused a gen 1. BankManager with the software upgrade for two years now and I ABSOLUTELY LOVE IT! Buy, install, forget. It is literally how it has worked for me. I LOVE IT!!

I have a thought that pieces of tape with different colors are better than marking with numbers. Place the pieces of tape so that they can be removed after it has hardened.

I have a car with LFP battery. Whats the best charging strategy as per you? I discharge it till 20 to 30% and charge it back to 100%

The "Zeppelin Knot" was new to me. Thanks a lot! *"Zeppelin Bend"

If you charge only to 13.5 volts, then resting voltage rests even lower ? If you charge to 13.48 volts DC on a 12v Lifepo4 battery, you are not getting full charge and balance the cells. All Lifepo4 batteries come with a BMS battery management system that prevents overcharging. Lifepo4 battery chargers usually charge to 14.6 volts DC to fully charge and balance. Then at rest they settle around 13.4 v to 13.6 v. Although I do wish all Lifepo4 battery chargers came with adjustable charge voltages.

How come many car audio fans charge their battery bank (high C rate) directly from alternator without any device as dc-dc charger ?

Loved the video. Lots of good information. I would like to see a video about how to set up multiple bank managers, I have 300ah of Battle Born that are about 4 years old. I would like to add 600ah more of a different brand. I currently have Victron chargers for solar, alternator, shore power and wind.

I use LiFePo mixed with lead acid. Doesn't matter one bit. Guys on youtube are looking for affiliate income.

Learn to stick to a topic and straight to the point this video couod be under 3 mins but Toomuch beating as round the bush 🤦🏾‍♂️

Hi Clark, i love your reviews, thank you for doing them. What I am curious to know about this specific model is, if the internal BMS would shut down at zero degrees Celsius and protect it to get destroyed when frozen.

On Sale for $129 on amazon plus $30 delivery

You should of had two demonstration rigs, which you show adding the 'bank-manager' device & its Bluetooth or control system. Holding the kit up doesn't do if justice imho

"You can abuse a Lead Acid battery" Errr... NO. If By "Abuse" you mean discharge below 50%, you certainly CAN'T

Thank you I love more than this series I love the entire channel You have been a great help to a going to be boat owner

Pleased to see that you were serious and still responding to comments. Great-looking idea and I am buying an air conditioned boat tomorrow I will see how the existing system works and if it is not up to speed I know it is marine ACDC and I will look up further on the internet now Best wishes to you and lovely to see a great idea pursued so enthusiastically

What was the output pressure on the air tank?

Sorry Clark - I can't stand hearing that bell. Could you maybe change it to a wave on the beach or something? I really can't watch your videos any more. sorry sorry. and the music is fine because I can skip it, but it's very annoying to hear it every time, too. Good luck and it's a shame because I would otherwise watch them all!

Hi is this stil available.?not for now but if i sail south

Good choice on the title of your channel!

Instead of finding a love interest to share your next adventure, why not take on a First Mate and crew? Your soulmate is probably located in a foreign port so don't restrict yourself to locals.

Nice video, with the information very well presented (as usual). If I may add on a bit, the "Charge to 80%" thing for electric vehicles is specifically because of the use of NMC (and related) Lithium battery chemistries that really don't like to sit at full charge. They also don't like sitting at low SoC either. "Keep them between 20% and 80%" is the rule for maximum life in most EVs. My own EV is from 2010, and the original LCO-based battery still has 80% of its capacity after nearly 15 years / 62,000 miles on the road; that rule is ingrained in the car's battery management strategy, and it appears to have worked. The LiFePO4 chemistry doesn't suffer from this, so if you buy a car with LiFePO4-based battery cells you can charge them all the way up and drain them down pretty far on a daily basis without worrying about damage. That can substantially make up for the lower energy density of the LiFePO4 cells in the EV environment. So what that means for LiFePO4 batteries in RVs and boats is that we don't need to worry quite so much about battery stress due to high SoC. It's still very important not to overcharge them, as you point out, but bringing them up to a proper 100% and leaving them there should be fine.

Granted more expensive, but I wonder if it would help to have two systems, albeit connected, to switch back and forth to. That way you could isolate one system to use while the other one gets properly charged

If I wanted to learn about 'lead', I would have watched THAT video..

I bought li-time lithium batteries along with their charger. I have always used the charger to top off/full charge the batteries. Is it hurting the batteries 400 ah in series for my van conversion? Do I need to turn off the solar occasionally?

Thank you for these wonderful videos!! Quick question, at 12:27 while showing the diagram, it looks like you spliced the red wire from the switch into the red wire connecting the float switch to the pump? In reality, that wire would connect directly to the pump correct?

Hi Clark, will the Bank Manger plus take the place of a BMS in a home built battery? Thanks

Weird my charges are charging lithium to 14.7 thsn disconnects and it trickles ?

Midnite solar, the kid , charge controller, ,is designed so you can charge all the batteries. It is infinitely controllable and every metric is user adjustable

The sun dictates the charge rate lol, for most of us buying into it nowadays

Great presentation Clark. I just got an email from Redodo announcing that they have created a 140ah dual purpose battery with ~900 CCA that can start engines. Sounds like a great idea for your next video. Thanks for the great videos.

This video, amongst other positive things, shows why LiFePo4 is a nightmare of complexity to you averagage user. This is why 'non specialist' people have to buy black boxes, fit and forget, and not really have a clue about what's going on! One other thing for sure: hybrid (LA mix) is a must for any boater.

This guy is wasting your time....making things more complex then they are. He do not physically understand what is happening, reason he can't put the simple logic of a LiFePo4 into words.into words
