Looking at this is like drilling for oil....

Thanks god bless I am Looking to buy hydraulic crimper

Non the less rather build a battery room away from everything no matter the battery type for safety in a solar or backup system

@highTechLab...can you connect the charg verter to a single phase 240 volts ?

0:31 Well, the fire is because there is a thermal runaway Impact of cell chemistry, when the temperature is above 240 degrees for these types of lithium ion phosphate these will catch fire, now such sudden increase of temperature created by this vertical sharp metal rod after striking it on this battery is what causing this fire. The striking is generating temperature above 240 degrees. Another alternative maybe Lithium titanate oxide battery.

We just picked up the white trailer that is exactly like this trailer. I am trying to get everything back into working shape as soon as is possible - we are headed to the top of the mountain!

It's an improvement over Li ion.

If you open up UL approved battery storage they don't compress the cells. They do put them in a fixture to keep them from moving.

Run a restaurant ?

Very good test Bro

Спасибо за информацию!

Top balance is not really necessary balance maybe necessary what I mean is just make sure there all the same voltage by Connecting them all in parallel and letting them set for a few hours so you don't need compression to do that, then charge to full and check with a multimeter to make sure there the same if you have adjustable power supply you can Simply put a little bit of energy in the one low cell, but the bms should do the same thing.

You have to have clamp pressure in the middle of the cells as this is where they bulge from the most. You should have one more set right across the middle and it’s a must for safety to add insulation between the cells. Several things wrong with this setup.

Why grid tied inverter manufacturer dont just give some settings to just by click of a switch you can use the grid tied inverter in an off grid settings?

In the OLD DAYS we had LEAD BATTERIES>

11 years later

meanwhile your are liquid flood back to compressor you may need to brush up on electrical a bit

#excellent crimping :D

great video thanks! so u hooked up the grid-tie-micro-inverters to the AC out of the off-grid-inverters?

thank you for this detailed tutorial 😊 may I confirm if the pv wires have polarity if they are not yet connected to either the solar panel or solar charge controller? I think I've installed the mc4 connectors the other way around 😅 (female connector to positive and male connector to negative)

How bout an up date on tge sigineer

Awsome set up but I can't believe you don't have a disconnect for your battery bank

DOES ANYONE KNOW WHO CAN REBUILD MY 48V 20Ah 60a LiFePo4 Scooter battery on the East Coast? I'm in RI.

Interesting, other tests had nothing happen but gas release like it did at first. Sure looks a heck of a lot less violent than NMC/NCA though. And like you said, much easier to extinguish.

WTF is the point? "I iz the mostester chargin' guy?!!?" Other than CZcams content CrEaToRzzz who would do this? Nobody. Thank god for channel blocking scripts. Adios.

Can I use battery cells without a shunt or BMS? Could you please go over options? I'm building two battery's for a off grid system. The cells are advertised @3.2volts / 320 amps.

- I wouldn't talk about "compression" as the name of the structure you described, but only about preserving the original dimensions. I've noticed that some people think that this kind of threaded rod structure is supposed to PRESS the cells against each other with a certain N force. That is a misconception. the purpose is to make only a structure that WILL RESIST a certain compression directed outward from the cells without letting it change the shape of the cells. If before the cells are put into use, by tightening the threaded rods, inward compression is caused to the cells - it is useless and possibly harmful if it changes the shape of the cells at any point! - I feel that you put the aluminum upper and lower corner pieces too far apart. Now there is a lot of unstabilized space between them for the cutting board to give way to the bulge of the cells. Personally, I would have placed the upper "collar" an inch lower and the lower collar correspondingly an inch higher. If the location of the upper and lower stiffeners were clearly closer to the center of the large side of the cell, it would indeed significantly prevent bulging compared to your current solution. So the cutting boards off and to drill new holes. - Many people who build a battery pack in a similar way also place a sheet of cardboard against the surface of each cell, so that they don't damage each other with a hard surface, with a soft sheet of cardboard protecting between them. - The threaded rod should also be coated with some kind of soft hose to avoid hitting the hard metal and damaging the sides of the cells. It is recommended to place the threaded rods as close as possible to the side of the cells, so that the cells cannot slide sideways under any circumstances.

This is the most ridiculous solar addition I've ever seen! This has to be some sort of joke right!?

Yea, Hi from 2024. Lots of fire and toxic chemicals and people dying. Deluded idiots are still making excuses.

And proof that inside is realy LiFePO4 chemistry and not something else is where? 🤔🤷‍♂️

How about a update on this BMS?

I don’t think the current-sensing shunt-bars are in the proper orientation. Many have the current carrying terminals oriented up/down, you want those oriented left/right. This way, air is drawn up through the precision manganese strips via convection for cooling. Although float current on the battery is small, discharge currents can be high enough to discolor the manganese without proper air-flow. Once discolored (purple-ish), their precision resistance is permanently out of calibration. Also, I’d avoid using metric dies on AWG wire. Metric with metric or awg with awg.

So we need a a 20k dollar solar setup and a massive generator to be energy independent?

What up cheddar bob?

Hot ... Damn ... !!!

you basically did nothing in 15 minutes - lol

So why do some LiFePO4 catch fire and some don't ??? Some are cheaper and aren't really what they claim I guess. I've seen pucture tests with alleged LiFePO4 and no fire at all.

Thanks for posting this video. Some people say compression is not required but the CATL 280Ah spec sheet I have clearly states for maximum life >6000 cycles the cells should be compressed with 300 Kgf for at least the first 180 cycles or 6 months. Charging max 0.5C @ 25 C.

Thank-you for sharing, I'm going to try this today ! Hubby & I will LOVE it ~ Appreciated your Clear Instructions & a quick & concise video : ) So Cute about your Wife & Lemons for her Bath : )

why are you polluting the enviroment?

Great introduction, very responsible.

Only warranty I have done are these modules.😢

Really cool idea, but honestly, these are just overpriced for what it takes to make it. Seems to me, that they want to make ALL of the R&D in the first year of selling. If they were more reasonably priced I would have bought 20. Just not worth what they are asking for them. Thanks for the information and video!

Get a soft start Programmer.

But my penis is not pointy and sharp like that spear. Is it still safe to use this batteries to power my doll ?

Groound mount?

I'm no expert but my crimps when cut look like a solid piece of copper on those individual strands are very visible

This bad video. To have the right test you need to overcharge the battery

I have punctured LiPO batteries which are very different many times. I have noticed that leaving the cells shorted with something metallic it makes it worse. If you would have removed the tool it might not have caught fire at all. I feel like leaving the cells shorted allows the current to create more heat than just a plain puncture.
