Dirt Cheap Lithium Battery! Cheaper than Lead Acid. You will love this thing!

How can you put 4 of these on series?

Please show how to connect these in series. Thank you.

How many of these batteries would i need to run an eco worthy 3000w 24v hybrid inverter?

Hate to resurrect a dead horse, but now that Tesla Model S battery modules are ~$300, how do we feel about those for a lithium solar setup? I understand you can only use 80% of their capacity, and you have to find customizable hardware, but I just don't see a better bang for your buck. Right?

Batteries are cheaper and I'll tell you why, because you're not forced to buy them all at one time, unlike a high quality inverter.

Very tempting for my van build. I notice these are Lithium Iron Magnesium Phosphate. How is that different from LiFePo4?

Portable and easy to use

how to calculate example: how many watt solar panel needed to charge 100Ah 12V battery?

where do you duy them? a regular store? What are they called?

Don't buy used batteries. Period. Lesson learned.

Am I not seeing the link to that MPP solar controller? Can you please hook me up with that I would love ro buy it.

Will, love your channel. Could you answer a question for me? I have 3 80ah AGM batteries now approaching 4 years old. Can you recommend a trickle charger and is there any truth on desulphication chargers? Cheaper the better and I can manually charge 1 at a time to save on charger costs.

Exactly which model is it? You never clarify.

I have about 100 of the original version 1 Valence U27 12XP modules which were part of a big contract for converted Ford transit vans in the UK done around 2010.. The conversion contract went horribly wrong when the converted vehicles were all found to be overweight and they were very quietly scrapped. The Transits sat around in a yard completely ignored and uncharged for years before they went to salvage auction and a year or so after this (2016/17) I got hold of them.

I remain simply staggered that many of them still have their full original rated capacity of 130Ah, even after I have thoroughly abused many of them principally by over discharging. They are not the most energy dense formats available by a long chalk, but boy are they resilient. Your versions (with the green cases) are a lot more recent than mine, but it sounds like the fundamental battery chemistry is next to bulletproof!

Oh… and (IMO) it’s pronounced ‘Vay-lence) as in the chemical bond thing…

Love the channel and all the great info!

I've got an idea for a video for you if you're interested.

People tend to have a bunch of DeWalt tool batteries, for example, once they start buying a few power tools. Would it be possible to Daisy chain a bunch of these smaller batteries together to build a small solar system to run your refrigerator on overnight?

Just thought it would make a cool video even if was to just disprove the idea.

Anyways keep up the good work! Glad to see people like you getting information out to people all over the world on solar systems.

Can I get a source, make and model for the controller/ac charger/inverter/Solar charger

Do these Valence batteries have an internal BMS that can be used? A web search comes back with "Valence Lithium Ion 138Ah batteries. Although these batteries do have an internal BMS they have to be activated and controlled by an external BMS."

I'm getting a 40lb trolling motor what Lithium battery should I get? I heard a 50ah would be ok?

Hey Will great video i just came across a pair of these valence u27-12xp for $300 is there a way to check them out as far as how used they are?? is this a good deal??

Will,
I need help with setting up a cabin with solar, can you help me?

I found a battery that I’m interested in.
Data safe
12hx505-fr
I’m trying to power 225 watts
With a 1200 inverter
And I have a 40 amp renogy
I’m hoping this battery will help me off grid.
Running a window unit
Lights led
My camper has a frig
And a of outlets that are attach and came with the pop up camper.

Waw very very ...

its probably pronounced "vay-lence" like valence electrons

May I suggest doing a test and review of the Limitless Cyber 12K batteries and and the Limitless Lithium Retro PRO 56 batteries, in addition perhaps also do a review of the XS 40-50Amp 12v batteries, etc. I have found these batteries to retain lots of power, but may not last as long of a life as these other Lithium batteries. Perhaps do a breakdown tutorial of the different types of batteries that would be suitable for certain usage types for example from RV/Solar stand-alone batteries, to high voltage draw batteries that likely used for competition car audiophiles. IMO, it would be great if there was an updated tutorial that would help users be able to configure a proper standalone LTO or LiFePO4 battery system that could not only have a battery delete, but insite in properly isolating a battery system for example on an RV which has a large 3000-5000W sound system. Knowing the difference in safety features and which batteries are ideal to use for high wattage use and knowing when a Pure Sine Wave power inverter is ideal to use for certain batteries. I just wish many LTO LiFePO4 batteries had a battery management system, but the key thing is to understand as well would be when these added features can end up becoming more of a problem vs. a benefit when truly tested in real life. I do love your video tutorials, however, I feel you can certainly help others expand their knowledge more if you are willing to widen your scope on already tried yet untested new vs well-known Lithium battery producers with safety always the main focus. With so many battery makers and some not even providing specs for there batteries, including tested wattage draw, I feel that you might expand your viewers even more with more similar battery tutorial videos. Remember, going cheaper on battery technology doesn’t ALWAYS mean safer/quality products. For example, it would be great if you showed your viewers how to create their own stand alone solar system for like a Subaru Outback or Jeep for those who truly love the outdoors, but would also enjoy solar powered battery system reliability.

I have ALL IN ONE 2424LV 2400W INVERTER with 6 24v valence batteries parallel connection im using 4 Guage wire all around is it enough or need a little bigger? Also i have a rich solar 200w 24v and im using 8 gauge is that ok need help please? Now I also connected a orion dc to dc 12-24 15amp directly to the pos. & neg. of valence battery im using 8 gauge and 6 gauge leisure to orion

Can you figure up a cheap system or something for helping homeless stay warm and lights on in winter? What kind of system?

Where can I purchase these batteries?

sharp kid for sure

Will, the best videos on solar I have seen so far kudos .. keep it going. ideas .. if you could please post some videos where home owners could convert their outside the home lighting to solar or make a home swimming pool pumps run on solar or charge your tesla with solar would be great. Great Job.

I am extremely interested in these Lithium Batteries! Do you still recommend them and are they still available?

So I ordered 2 from your link: Valence 40ah both used. When they arrived I realized I should've only bought 1. The reason: 1 was charged(green light) with all the cables and connections but the other... dead as could be and obviously the shipper knew that. The cables were cut and pulled apart at their bases so no way to connect with other battery unless I purchased brand new cables and connectors. I can't even charge it!

Hey I couldn't find then in Ebay
What do you this battery pack of 8 from a Misubichi Outlander?
Lithium Battery Pack 8x LEV40 Yuasa cells Mitsubishi Outlander Powerwall 40Ah
I m of buying 4 of this packs to an off grid

Where did you get your college degree? I have 5 college degrees and 5 minor degrees.

Can you use 3 of these for a 36 volt system for a trolling motor? I though I had seen they were rated @ 30 amp max draw? What do you think?

obviously you are very articulate about solar systems but your explanations are not simple enough for a senior like me. how can I get clear basic information to build an emergency system for my home?

What brand and model is this battery?

Most medical equipment is plugged in all the time. The battery is mainly for emergencies. So they should hardly ever be discharged.

If four of these were in series for a 48v golf cart, would they be able to discharge enough amperage to work?

Awesome videos little mindnumbing at times but really helpful

Can I use these on my trolling motor

Hello, I know you don’t do consultations but do you know anyone who does? I’m having difficulty but followed instructions correctly and I can’t connect to shore and my batteries drain fast and charge slow. Even with the alternator connection. If someone knows who can help I would greatly appreciate it. I don’t have local resources where I live.

I have 16 batteries bl_16/t875. 190 6volt how many lithium batteries do I need what do I need

Will they work for a golf cart??? Please reply

Can be used a starter battery for a car?

I don't compare the price of something new to the price of something used. I'm hoping the next battery advance comes out before I need batteries. I want to skip lithium altogether.

you can buy 30kw used arround 80% soh, at 3000euro.

Excuse me can you tell me which is the best battery for the system

Cheap and easy. .......So another words a great date .

Chances are these have to be replaced in the hospital after a certain amount of time no matter what. and that would be way before it would not be dependable.

Okay. They’re good batteries. What do you do with it???
