ECO-WORTHY 48V 100Ah 5120Wh LiFePO4 Server Rack Battery

I have flashback of the manually fixing unbalanced cells. Manual chasing them around. I don't miss those old days.

Two of six batteries had issues. Months of searching for answers..

The day the Active Balancer was purchased to fix the "Beta Box" with 5 year warranty. I was being nice and not bashing them. The unobtanium BMS and lack of support. That is why the quest to find other brands and gave birth to this thread.

It worked.

Yeah I was doing that on my home made 30kwh packs I built with grade b, half swollen cells. Or my lithium polymer packs. Or my tesla packs that I took down from youtube. It is not fun to balance those things for weeks on end with home made resistors packs. Gets old.

The birthing pains. Scotch will easy it somewhat.

I don't even know how to respond anymore. This is pertaining to ecoworthy pack.
Yeah it's crazy, there's a huge weight difference between a 100Ah rack mount and a 280-330Ah big boy.

Clearly he's not aware of the existence of 48V 15 cell batteries, you can't explain everything not enough time in the world.

I can only speak for myself - I've immersed myself in learning about solar/power/ESS for about 18 months. I tend to dive pretty deep. I've recently started getting frustrated by comments like this (and repetitive questions to which it's easy to find the answer) and I think just letting it go is the right call. If I see someone advocating for something that's unsafe I'll definitely speak up. At least then the warning/counterpoint is on record if people read it.

Point though is I've caught myself forgetting that not very long ago, I wouldn't have known what most of this meant. Or even about nominal voltages, or the fact there are 15S batteries. I'm the idiot who thought 'P-' on the first BMS I tried to wire up was for positive leads. There's one less BMS in the world, and much more informed me though. I hope they are able to increase their understanding, but yeah, not worth the effort. Most people need to have one of 1) experience a thing, 2) be open (even vulnerable) to asking for help/being corrected, or 3) curious to a fault.

At least in this case, I could provide an object lesson on why I did not buy 280Ah wall mount batteries for my basement and chose to DIY and assemble them in place. Or why I'm carefully considering the 100Ah variants or self-built 100Ah cells for my RV. Getting that 100lbs in the front compartment is about the max I ever want to do. Heh.

For what it's worth Will, I hear ya.

Sometimes it's better off to not respond.
Maybe ask them to re-read what they wrote or question their line of thinking.

Why would you need more than ~5KWh storage to run a small cabin or power a portable cart....

Clearly they don't understand what they think they know.
 
Imagine if you got a Tesla and it had 5% less range on the first day. And you agree that you should limit the capacity by 40%?
To be fair Tesla's are notorious for not hitting range.


I wonder if they will change the way the temp sensors are mounted after watching this video, Will keeps driving the quality of manufacturing through exposure 😆

Really depends on how you drive the Tesla. I've had 11 so far and still have two. And many other EVs. You can hyper mile them and get crazy range numbers. But if you drive them hard, they will get awful range. Just like a gas car.

And you will get the full capacity of the Tesla battery and you can track it with apps.
 
1. Valid concern, sometimes you really have to check if a battery is 15S or 16S. 48V is an old telecom standard to keep the paperwork under 50volts.
2. 100A is a good size for many users, easier to handle etc. But yes if you need 2+ a 280/300Ah battery unit is better.
3. Yep poor programming and cheap unmatched cells. Consider the price of the units, can't buy cheaper.

I replied for you Will, don't take it so personal !!!!
 
A friend and I installed my 48v 280Ah battery into my camper and I thought I was going to have a hernia. I can't imagine trying to install 225 lbs of battery into a rack mount. I would want a fork lift to do that safely.
SAME. I could use the forks on my tractor if there was room/clearance, but there's not. And I enjoy building batteries, but I don't really want to do all the wiring/torquing/etc. in the RV for multiple reasons. Two back surgeries....helped me out for sure, but I'd suggest not having back problems. :LOL::LOL:
