Lifepo4 Basics and What You Need to Know!

I like the simple straight up on this infermation!

Could you please speak to stacking batteries sideways upside down things like that for different configurations for solar. Meaning can you lay them sideways and stack them? Or do they always have to be standing up like a regular battery? And nobody has really addressed if these batteries are safe to be inside your house rather than outside like let acid

280 amp hrs ,, 12v
How many solar watts to comfortably charge these lithiums .??

Electrician here just a comment on the last point you touched on, should you be touching a terminal and the casing depending on which cell you are touching the potential is going to be between max 3.5v to 48v dependant upon the amount of cells connected in series , creating a pathway through your body by contacting the unprotected casing and a terminal will in the worst case (48v)be a minor ouch moment and more likely due to skin having a very high electrical resistance value ,voltages under 24v are barely felt , so no , physically shorting the case and a terminal would create such a small current pathway if any , its not a concern .. something with a much lower resistance value , ie anything metal touching the bare casing and a terminal would create a serious fault current which if nearby could result in a flash burn and lead to a run away .. oh btw it would make no difference if the cases were positive or negative , the same potential exists only the polarity changes

It can replace lead acid battery.

Can we use it in inverter .

The connection should be series or parallel.

thank you sir. very informative.... I am a radio amateur and building a pack for emergency and portable use. Unlikely to use solar in Seattle area.... I am using a Daly bms and will be 4 VariCore 3.2V 90Ah LiFePO4 batteries. Walk through of going from batteries to working pack would be great. I will follow your top ballance procedure after I watch it.

I will see after top balancing but all of my batteries read 3.280 except one that is 3.200..... when arrived. thanks for the great video.

I made a battery pack of 16s 105ah . With Ant bms . The problem with the battery pack is it is not getting balanced. Should I buy a bms with balance option?

did you do a solar charge controller setting video, ie a cc that had lead acid in mind when made, for lifepo4

Can't believe the case is not isolated from the terminals of the cells! If it was going to be any potential then surely it makes sense to be -ve!

The volum level is to low on the audio, I'm in a garage with some noice using airdots, I can not hear you ...

Great video, like the 80% rule. Confirms with what I've heard about prolonging battery life. Do you recommend putting thin two sided foam tape at four corners to reduce rubbing also? I've seen it done to keep them from rubbing in a trailer but not sure how it effects compression? If i stick to the 80% rule it shouldn't swell I'd think.

A word of warning. Not all suppliers wrap the bottom of the cells. As a result, if you wire them in series and then place them on a conducting surface this is likely to short out any cell that has its negative terminal connected to another cell's positive terminal. I nearly fell into this trap as I placed some electrical heater pads to the underside of a sheet of aluminium to provide even cell heating. This may not apply to all cell suppliers. I am in dispute with my cell supplier as their cells are only producing 295Ah when they are rated at 310Ah and I am not impressed with their after sales service. If I don't get compensation I will publicise the supplier's name for buyers to avoid them.

Hi very informative just a question, I live in South Africa and planning on building a panel van camper next year, I'm planning on going to desert and semi desert areas, the temperature can range from 0 to 50 degrees Celsius in a day, have you got any advice on how to keep my batteries from getting damaged

20% charged = 3 v and 90% = 3.35 v ? Somebody has made tests to find these safe limits ?

Интересно, почему нет бмс с отключением заряда на каждую ячейку персонально?
Те, где уже высокое напряжение от заряда отключить, а остальные продолжать заряжать.

Thanks Will, that was a great presentation

I was hanging out for comments about active balancers , but you left me high and dry 😕

Alot of BMSs tend to have an over charge voltage of 3.75 +/- 0.05 per cell. Whats your view on this?

Comprehensive and informative. Thanks.

can you tell us the the voltage and temperature range, i missed the part where you told us.

I am not sure why you seem to think that repeating the information 2 or 3 times is necessary? Saying something once to an audience that is interested should be sufficient and would shorten your videos significantly. I find the repetition extremely annoying. Otherwise, the videos have good information.

Thanks. I wonder if one was to do all these good practices what is the value of this chemistry vs another chemistry. I am investing in this form factor and chemistry currently. Should other chemistries be considered when taking into account these optimization strategies? Are the differences small enough to make the choice a matter of personal preference? I understand my questions are subject to qualifying use applications and considerations unique to the user. As a metaphor, steam engines are superior until you factor the good practices required not get blown up and worn down by maintaining the system.

i use 24 6 volt deep cycle set up to 48 volt . my shed temp is - 24 below to 120 deg. don't think these would work for me.

Thanks for this info, i have been trying to find the men/max voltage for my new lipo-4 battery

Great video and you answered so many questions i had on Lifepo-4 batteries. I have used led acid batteries for years to power my Ham Radios and recently purchased a Lifepo-4 20A 12V as a backup so i know charging and discharging are different so i am having to do research and you have helped a lot as this is all new to me.👍

great series one question what size height/width /thickness are they I would like to build the the compression case while I am waiting for them thank you for your time joe

Nice safety points man, I bought a 12v LifePo4 Valence battery, it has a built in BMS, it's a 40Ah battery so I am trying to turn it into a solar charging power station with a decent 1000w pure sine wave inverter for emergencies and on the go as well. Thanks for sharing your knowledge man, cheers.

The temp sensor inside the bettery will prevent the battery from being charged too cold ?

Amazing video. I'm subscribing!

What is .2 c?

Very well done you reinforced what I already knew but one thing I do a little different is that I charge once a week to 13.8 seems to bring cells nicely in balance.

Hi TheWilltoBuild, is there any difference in long life cycle life if I make a 12v battery out of 4 cells of these eve vs hundreds of small 18650 batteries? Since these are new, I wonder if 18650 batteries have better quality or it's the same since both are lifepo4 cells anyway?
Thanks btw for the tips and the great info.

Would you not need to set the solar as bms should shout everything down?

I'm replacing lead acid with lifepo4 in my mobile scooter 48volt, any suggestions

Hello everyone.I have batteries eve 280A/H from Docan Tech. What is the stud torque for these batteries. Thanks

Making my first battery pack using 3.2v 100ah 1c lifepo battery for an ev. using 30s bms. guide me. i have very less knowledge about the safety.

Sounds like an adoption agency for batteries, they have high expectations and get unhappy very easily.. great vid btw.

A nice PDF with this information would be VERY HELPFUL!

Great video thank you! GOD BLESS!

👍👍👍

Thanks for always imparting with simplicity

can you comment on Grade A vs Grade B...does it really matter for energy storage ( not ebikes)

Where can I get instructions or Do you have instructions on how to build
84V 50Ah lithium iron phosphate battery pack for my E-Bike?

battery 24v 100ah Lifepo4, charger 20 amperes is it normal or is it very amperes?

Super useful 👍 thanks 🙏
