Needed to enclose my DIY battery banks, and thought I would put the battery cell shipping containers to use. Trimmed them down for my needs. I think they turned out good for DIY/Sort-Of. PlexiGlass Covers soon.

I dis-assembled my Banks/Cells last night. In my un-wiring and thinking through my setup, looks like I mistakenly had/have a Negative battery lead parallel to the BMS B- / P-, through each Battery Breaker. Thus bypassing the ability of the BMS to disconnect the cells upon over charging. This...

Always good to learn from others’ mistakes for sure. Fortunately this one was all My Fault. No arcs or sparks, no fires. Nobody hurt. My system will be better off because of me learning. Now to find (4) additional 280ah cells.

Much agreed. That is exactly why I am on this forum. I will never recoup my investment of Off-Grid, other than independence when things get tough. Definately getting tougher out here. Good hearing from like minded people. /Another older man out here doing what I can. Common rant lately...

I'm 62 yrs old. With some thought ahead of time, one can get much accomplished working with leverage, pulley's, ropes, rails, etc, for installing panels on the roof. I rigged long 2x6x16 boards as rails. Rope tie a cradle for each panel and lift to to the roof for handling once lifted on top...

I picked up (32) LF280K cells yesterday. At the 18650 store. 3 hour drive. Well worth the trip.

I think in most of our cases, "It's a 16S program".

For me, they are always just too difficult to re-train. I'll keep the one I have. She tolerates my power addiction. I using "TimsElectric" theory as well. It works at my location/setup needs. Also Scalable.

Looking good Tim, Can't wait to see how the project moves forward. Very cool install.

I did "Flee", proud of it. I now call the place I flee'd to Home. No neighbors, no noise, no paved roads closeby.

This is the crate I received from 18650 Battery store:

2022 Massey Ferguson 1840M. Great Tractor.

...yea Pizza's in today's world. Picked up (2) 3 topping Domino's pizza last night, $45.00. OMFG! Time to shift to frozen pizza & cook it in my own oven. Save up more for DIY batteries. ?

Driving to 18650 store to pickup (2) sets LF280K cells for 48vdc banks later this week. 3 hours from the house. I will let you know. Though the reason I am using the 18650 store are many positives from other DIY Solar forum members. Quality cells from a reputable source. My first DIY battery...

It comes down to "Mis-Wired" BMS - Battery leads. And then overcharging and BMS unable to stop charging. Here's a photo of the blownout cell from Lower Bank. Cell #9

These components, JK BMs RS485 interface and USB adapter to SA have all been very Plug & Play. I connected both of my DIY banks the past few months. Great solution.

I have been using it almost One Year now. Would not run my solar system without it. Gives very good insight to what is happening within the system. Enjoy the detailed statistics. Highly recommended.

Hopefully those on the list respond with their paid order quickly.

If it keeps dropping, might be time for another road trip to 18650 Store.

Keep growing, build your own warehouse. Make it an example of all things "Current Connected". Many of us here directly support what you're doing.

If DIY is not your thing, pull up your preferred Solar Supply Company on your web browser and fill your Cart with a pallet of prebuilt batteries. SOK, EG4, Trophy, BigBattery...They will happily deliver them with your paid order. I prefer to pay for mine with improved DIY skills over time...

@HighTechLab I think most of your videos to date as just fine. Plenty of polish already. You definitely put out good points for learning about the topic or product. (y)

No compression.

Follow electrical standards as well as you are able, and document everything. Keep a wiring diagrahm printed out close to your equipment. Document Turn-On/Turn-Off procedures. Document everything. Then possibly have your HVAC/Electrician make an on-site visit to do a walk through with you to...

Working slowly getting my Growatt 5000 units installed. Running them parallel inside my shop/garage area. 240/120 volts. Not quite connected to main house just yet. Long process for me. Thanks all for the helpful threads along the way.

While not the biggest consumer of the 18650 Store EVE LF280K cells, the (36) cells I have from them ALL test above the rating. EVE LF280K V3 cells test at 299ah-304ah, earlier versions all 284ah-286ah. I would buy from 18650 Store again when I need more DIY Battery Bank cells.

Yes, for me a 3 hour trip each direction. I let them know my expected arrival time, They had my order ready on the pallet. Opened it up before loading to inspect the cells. No issue. Had me loaded in less than 20 minutes.
