ECO-WORTHY 48V 100Ah 3U Server Rack LiFePO4 Lithium Battery with Bluetooth（Version 3）, 5.12kWh Capacity, 6000 Cycles, 3U Chassis, Perfect for Off-Grid, Solar, Backup Power

First, I live off-grid. I have 2 EG4 6500ex inverters which support 8k of solar each. currently, on a full sunny day, I get a bit more than 8k of solar coming in. already had 6 eg4 batteries but when off-grid, 30Kw isn't really enough so I decided to try these as they are very inexpensive.I ended up buying 2 of them and in the couple of months I've had them, they been pretty flawless in operation. They charge well, use the full capacity, although the eg4 batteries get a bit more than rated capacity, these get dead on the rated capacity. I don't really care for the cables they included preferring to make my own from 4/0 welding cable.I'm going to end up buying another 4 of these at some point as they are a really good value.

This battery is great. I received mine today and put it through it's paces already.I charged it at 20 amps, and drained it at 20 amps from 100%. Capacity on the first cycle is as advertised.The kit comes with some accessories. The included parallel cabling quality is questionable but I've not tested it to prove either way.I found 2 Bluetooth apps to use. One in the app store called eco worthy then the one in the manual with a qr code that leads to a different play store app which is poorly written and mostly Chinese language . The one called eco worthy seems official and operates better.Edit after owning a month:I'll Be buying another one of these soon. 5+ stars.I haven't figured out top balancing yet from the app but the cells all settle to the same voltage once resting, either fully charged or fully depleted.

I bought two version one batteries and both arrived without damage. Price ($800) was one primary driver with free shipping. My only gripes are the very short blue tooth range and the blue tooth application does NOT do much other than tell you basic information that we all need. I do NOT believe the application allows firmware upgrades and I believe they are using a BYD BMS for the laser welded cells. Therefore, time will tell as these are backed with a ten year warranty but with all of the tariff issues I hope things will be fine. I just ordered a third battery which I believe will be version 2 as its coming in from LAX (2400 mile trip). I will update this review as warranted. Also, don't count on any real documentation regarding BMS /CAN / RS485 communication unless you purchase the RS-485/USB cable to see more. However, they do communicate battery to battery using the RS485 cable but the application only shows one battery at a time......

Bought the ecoworthy battery and inverter combo elsewhere for an amazing price. Decided to add another battery as well. Seems to be working perfect. Currently charging from solar and dumping the juice into my Lightning EV as I type this.

I like them so far. I got three of them for a good price in anticipation of the new Trump Taxes on imports. Two are charged up and ready to rock. Getting the other charged tomorrow. Heavy at 98 lbs, but it comes in a steel box.Unable to get the handles attached to the box. The holes in the case don't align with the slots in the handles. Sigh. So they lose a star.I figured out the handle thing. I had oriented them wrong. They stick out the side, not the front. Obvious once I understood they were to slide into a server rack.

This Battery is awesome for the price! Easy set up, good quality, nice bms features. For the price I don’t think you can find a better or equivalent deal.

These batteries arrived in good condition, were balanced, and easily set up 10 in parallel to support an off-grid solar power system. After using them for a couple weeks and having a few dark "challenge" days for the system, these batteries are showing great depth and I am happy with them so far.

No instructions for the rack,and the you tube video is kinda vague, it will get you far enough you can find your way without the full video.Prepare for a short work out if you don't have help, the batteries are kinda heavy. If you don't practice green zone lifting you may injure yourself, my advice, get help lol.Assembly is fairly easy, it took me a few hours by my self, but i was watching rumble/YouTube and took my time because I was trying hard not to hurt myself. But it is now all Assembled and heavy, heavy, heavy,lol I can't stress it enough.
