ECO-WORTHY 51.2V 280AH 14.336kWh Beasty Battery

Trying to figure out how he kept this secret over the weekend! Dude's killin it.
Ahh I remember the good old days when the Wife would ask how much that $2000 item costs and I would tell her $500 and she would go oh well that's okay I guess, it looked more expensive.
Now she Googles the Make and Model of all my purchases.
I tell you there is no more trust left in marriages 😫

"If I had a basement and a place to put a bunch of these I would be all in.. wait how would I get them there? tooo heavy"

I wonder if he told her yet about the basement....all built in 3 months time...amazing!

I so want a basement but we don't have them when your elevation is 10'

That might work if you rip off the 1 in 15 and pass it off as a 5k?
 
To my surprise, it did not feel like it was tipping over when I was moving it around. Although I only moved it like 6 feet and went reaallll sloooow. I wanted a battery with wheels as there is no way for me to move 300lbs unless I rented some equipment and got some help. The wheels made it very easy for me. So far, it has worked just fine. Came with 2awg cables and plan to replace them once my 2/0 cables and fuse arrive.

Once in place turn the red wheel to lower the pad behind the wheel which should make it more stable and lock the battery in place

I did. I have it up against a wall and tightened the front two. It went over multiple cracks and concrete stress cracks without issue. Don't do what I do, do what Will says (y)

I tightened up (Lowered) all the pads when I tilted it up out of the box. I was worried about it kicking out and slamming to the ground.. A couple of those cracks helped give it something to grab on to. I also had it where it wouldn't flop over because of the Fence and 4X4's would stop it.
 
So if each immersion water heater is 8 ohms and I have 8 of them that makes one ohm. If each one can take 1500 watts then that is a water cooled 12,000 Watt dummy load.

So at 51.2V it should be 51.2A or 2,621 Watts. If the max discharge current is 200A and I am running (average) 51.2A I am around 0.25C

I added two more but didn't have a picture of it.. I raised the pool temp by 7 degrees so far using it as a dump load and battery testing. The thermal blanket didn't hurt either. I just hate wasting good free electrons.

Discharge Test 1, It was charged a little fast at 100A then sit for hour. I did see some imbalance ~40mV the first time. So let see how it done.

Let the hunger games begin. I had to reduce the current because I kept popping 50A fuses even a 51.2A.. I pulled a few loads to get it down. So let it begin, again.

My pool is must a decimal point a little warmer

I had the Victron set for 300ah so it wouldn't max out. That is why it says 3%. Not bad for the very first test and it is a cool 55F

Well Bob it Sounds like time to open her up.
Should you run into problems with the Screws or Bolts, here is my Handy Guide on proper tool selection.

I always preferred my ceramic diamond plated cutting disc 😷

I charge it while I work I discharge it while I sleep... It's a pace-based BMS. Already tried the JVD software didn't get anywhere.

It's been charging up on solar all day so we'll run it for another test tonight.
 
I had a bet with somebody when we got locked inside a tower site where some goomba lock the gate and we couldn't get out the forest. It was night time the mosquitoes were horrible.

He swore by his DeWalt battery operated band saw and proceeded to try to cut the lock and chain.

It was an exceptional case-hardened badass steel and it was taking him a while.

I walked over with my trusty battery operated DeWalt angle grinder and made short action through the lock itself cuz I didn't want to hurt the chain because then we'd probably have to buy a new one.

He bought dinner that night 😆

I'm on my phone so I found the fastest generic image I could...
 
I finally got the computer to talk to the beastly battery. I have two softwares both are Pace based.

I'm connecting through the RS232 port. I know somebody who's very happy right now..... And I know he's going to rub it in 😝

It's been charging all day long..........

I'll give a screenshot of the balance when I can I see the minimum voltage differential is 20mV in the software. The LP4V1 The fault was 30mV so I'm happy with 20 mV.

2 years ago I was happy with a 100mV, what a nightmare that was... Okay those days are over I'm not going back there with the "beta battery".

We've come a long way baby!

I don't believe I am going to need to do another capacity test. That was kind of anticlimactic in a good way. It surpassed the BMS Full Capacity that was programmed for by 3.6% so that is freakin' awesome.
