I’m new here, and shopped the market high and low for a 200Ah +/- lifepo option with consistent reliability and reputation. The good options are still pricey, the cheap ones cut corners. So I just ordered 230a eve cells from Amy and a Overkill bms and will build one myself. The knowledge base...

Just one of many SHTF trends. The car bubble finance is bursting - repo's skyrocketing. Car prices up 40%, homes 25%, rent 40%, groceries 25%. 20M people are about to be evicted - they can't pay their rent. A bazillion dopes bought a house at the peak with rates climbing and can't sell or...

As I commented up-thread, this is a super nice way to construct a DIY pack. I took design cues and adapted it for my project. I have a low space where the pack installs - 10 1/4" clearance and my pack is 10" tall. So instead of the bms on top it's on the front. For the compression rod covers I...

The virtue signaling is strong in this one. We're going to nominate YOU to pay all the student loans! And make sure you open up your yard for a homeless encampment. ?

So the DIY route is roughly a grand less? Worth it IMHO. Plus you get to learn all about how it goes together. And the battery is just one part of the whole package, if you're talking about a PV array system.

Amazing. And what a harrowing story. My wife's cancer is abating as well...nearing the end of the second round of chemo. The swollen lymphs are gone, and no side affects. She feels great. (y)

I pre-oredered Eve LF230 cells from @Amy Zheng on 11/30/2021 for stock inbound to their Houston warehouse. Got FEDEX tracking today. Very easy to deal with, very professional, response is very quick. I anticipate grade-A cell excellence. This is an outstanding source for a DIY pack build at a...

Got our Gen3 and setup for the RV - in a word, just outstanding. It's so simple and works so good, all tech companies should strive for this level of service and performance. Not only is the hardware excellent and easy to configure, the internet access, app and supporting service is nothing...

As a subscriber to Joel Skousen's World Affairs Brief I get the weekly publication. There's a section every week on preparedness, and a couple of weeks ago it was about DIY solar. I replied back to Joel that the best resource (unmentioned in the brief) was Will Prouse and this forum. So this...

I'm a proponent of DIY having done one, but the learning curve is pretty steep and I'm a very accomplished DIY'r with tons of tools and happy to buy more. For an awful lot of people I just don't think it's a good option. For many more that THINK they could do it, realistically they probably...

Here's another one... I have zero fear of my DIY battery pack catching fire. ZERO.

A Temco hammer-crimper is like $25. I consider that the very minimum. Two screws and a hammer isn't it. And you don't know what kind of crimp quality you're getting unless you cut it open, or put into service and measure resistance and heat. I get the shade-tree DIY angle for sure, I'm a master...

I think not. Everyone I’ve shown my diy pack to gets that deer in the headlights look. :oops: :LOL:

That would be 'tongue'...not 'tung'. ? A lot of people buy stuff if they think it's a good deal. My son's ex-wife was a shop-a-holic - if it was on sale or a good deal she bought it whether she needed it or not. At one point you couldn't walk through the garage, then they got warehouse...

https://www.docanpower.com/index.php?route=common/home I got four Eve LF230 for $454 delivered. Working very well. It’s a pretty steep learning curve on DIY battery building. I would never have attempted it without the help of this forum.

OTOH, heavily mod’d forums are a bore, annoying, offensive, and people go elsewhere. Some will use the excuse of search indexing, but really it’s usually a few anal-retentive nannies with a heavy hand or an ax to grind. I left an enthusiast owners forum some years ago cuz the mods decided my...

I have a pair of these fine-gauge crimpers for the RC leads we setup - worked just perfect for those super fine wires and terminals. I got uninsulated terminals, crimped, then heat-shrinked. Worked out dandy. And instead of putting a ring terminal under a battery post I tapped the bus bars...

I had a similar idea with the lexan guards and such, but starboard instead of plywood, and no springs. :cool:

Fairly new...although I did built a DIY pack and enjoying it and the process. A few points come to mind. 1. cost - none of the materials cost included a myriad of tools required to do this properly. Cable cutters, terminal crimpers, insulators, fuses, and on ad infinitem. I spent at least a...

We all have concerns. AFAIK my cells just got dropped off at the house (ring doorbell). Over lunch I'll inspect and put a meter on them, take a pic or two and report. EDIT: The inspectors are on it... :ROFLMAO:

"Whatcha wanna do..." You whipper-snappers are probly too young for dat. LOL Pure Prairie League

Victron FTW. Friends don't let friends buy renogy. PERIOD As so well explained already, you need a regular starting battery for your engine, isolate your house circuit with the lifepo4 battery(s) and a Victron DC to DC charger. Live happily ever after. Got a solar panel and charge controller...

I'm new here, starting a new thread on my 430W installation, so I can ask questions when they come up. This forum has been a wealth of information. I have also been scouring the 'net for, and learning about, LiFePo4 batteries as well. I'm not sure where I first saw strut channel mounting for...

I don't recall your battery size or type. For a lead acid battery an ANL or post fuse is fine, for lifepo4 a class-t is appropriate. It should be sized at 125% of your maximum current load to the battery. I didn't see an inverter size. A quick look says you have AGM batteries but going to a...

First you need to know how much power you use in a given time, over a day or night, or whatever interval you'll need to recharge for. A portable array is do-able, a couple of panels and a charge controller hooked to your batteries may well do the job. But you need some kind of estimate usage to...

If you're using compression rods, all-thread for example, just snug them up so the cells can't puff. They don't need actual compression. Don't over-charge them, don't over-volt them - that will prevent them from puffing in the first place.

I like the display for a quick glance. A meter also counts in and out so it is much more accurate than the bms. Which only reports SOC based on cell voltage. (EDIT: Also counts coulombs but fails back to SOC by voltage depending on use. More on this later in the thread.) A meter you zero out...

IMHO a 2A or 4A charge won’t make much difference- whatever charge voltage you set, they will taper current as the battery voltage reaches that setting. Some chargers have a duration, some sense tail current - a level that is decidedly full charge and terminate. Bleeding one cell at high knee...

Duckduckgo FTW. Google and msn are evil. As is all those silly social media sites. Just log off and be happy.
