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

This is my 2nd battery order. I ordered 1st battery to test it out. I have the battery for about 2 months, the quality does match the description. One thing that is lacking is their user manual and tech spec. I used a different brand of inverter; therefore, the communication protocol needs to match. It took me a while to figure out. Their customer service support is awesome responsive but their tech support is a little behind. I have 5 stars because this product is relatively affordable and customer service. Once the tech support got back to me with the configuration needed for my inverter, everything seems functional.

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.

I purchased 2 of these batteries for my off grid solar system. Overall I'm pretty happy with the batteries, but I was a little worried about the initial differences in the batteries power absorption. The first battery charged up to 100% within about 5 hours at 15 AMP AC charge from My sungoldpower AIO inverter. (small 5000Watt). I cycled the battery once using a 1500 Watt heater and it then recharged to a full 100%.The second battery, only charged to 96% and the BMS alarmed and shut down charging because one of the cells was full. So the max charge only went to 96%. I let it sit on the charger overnight thinking it might balance out, but it did not. Next I cycled the battery with the 1500 Watt heater and after that it charged to 100% (i just left it on overnight, and never checked on it).I still think these are a great value, but I'm a little worried about consistent charging, and the function of the LIFePO Cells, but really at this price, I think they will be fine overall. I will see how these 2 go, and report back if I buy more.I used the Will Prowse discount code to purchase. With that code it was cheaper on Amazon to buy the batteries individually instead of in a 2 pack (because of taxes and other charges).

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.

Bought because of Will P. review, and from first impression I wasn't disappointed. The packaging was Better than my other 6 batteries from 2 well known companies. I then ordered another battery. Thank you.

Plug in and my inverter found the batteries. Setting dip switches are backwards in the pic but the numbers are correct. Seems good but time will tell. This is the only battery I have on my EG4. Not sure if other batteries if you could see more on the inverter. I'm happy with it

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.

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