ECO-WORTHY48V 100Ah LiFePO4 Lithium Battery, 5.12kWh Capacity, Server Rack Battery with Bluetooth, 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.

Exactly as advertized. Best price on such a thing anywhere. Shipped well and quickly. Good build quality!

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.

The item came before time.

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.

they work great. I downloaded the battery monitoring program for my Windows Laptop. Has detailed battery monitoring

Ordered 2 batteries to augment my system that will consist of EG4 12000xp, EG4 Chargeverter and HF 13000W generator running on NG. Very pleased with the out-of-box capacity and balance of the cells in these batteries... enough to have me ordering 2 more!

I bought 4 of these as a set and they've been my rock. 20kw of battery for a very low price. I'm currently using them to charge my car as well as emergency backup for the house.
