silly me thinking that you can update the firmware.... well you can't. and silly me for thinking two of these batteries will talk to each other...... I have two of these batteries and configured them as specified in the manual. Each battery has 100 amp hours and the battery pack says 100 amp hours, even though it should say 200 amp hours.

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

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 have brought two 51.2V server rack battery and the shipping was fast and the batteries are amazing. The batteries also communicate with my inverter.

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).

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.

So far it’s better than expected for the price.
