Nice battery! I'm not sure how the Bluetouth is secured from others. Is it safe? Can others people connect via the app.. ? Please explain how to use it safely.

Love the quality amd craftsmen of the product as well the efficiency

GOOD PRODUCT

Battery is working perfecly. Easy to install. Good value for money.

Excellent. It provides a superior alternative to conventional work batteries.

...however I saw no change in colors to the LED during the charge process from 60% ...perhaps it was because I did not unwind cables from shipping. Next time I will charge with charger cables extended.

Works like a charm!

GREAT CHARGER.EXACTLY WHAT I NEEDED.

A készülék tökéletesen működik. Masszív kivitelezés. Egy negatívum. A futár nem tudta háznál lerakni, mert nagy a tömege. Ezért nekem kellett menni a depoba átvenni, és utánfutóval hazavinni a csomagot.

Picked up the Delta 2 Max recently because of this server rack battery "hack" seen on YouTube. Just finished charging up the batteries and device, plugged it in and it just worked beautifully. What more could you ask for?!

Bonus, the total cost of this system is less than one of my previously purchased, 5kW systems. This doesn't beat it in every regard, but having 2X the battery capacity for about 2/3 the cost isn't too shabby.

Just love that the tech is getting "easier"... so far so good! The Wattcycle battery was easy to set up, plugged right into my Luxpower 6K to charge up, and then I connected it right to the EF.

I agree with earlier feedback, it'd be nice to have the default display screen as the one that shows you most of the high level info you want to see anyways.

Maybe a future firmware update will allow you to set what you want the home screen to be when you first touch the screen.

Works as specified. Minimal heat dissipation.

It charges my 12/100A Smart battery very quickly. I'm currently debating whether to risk voiding the warranty by cutting off the crimped lugs and soldering on an XT60 connector.

Very fast delivery

Very nice dimensions and weight. I like the overview and settings via the app.

Velmi rychle a bezpečně doručeno

Super

Great Cable. Im using it with my delta 3 with stackable battery

Great service and so far so good with the product

Cable worked perfect for my delta 2 and was able to add it to my plugin solar setup.

All ok

Some startproblems but now its ok. Manual is not so good. Youtube was helping me. How to use the smartswich with 4 applications?

Estoy contento con la batería tiene unas medidas muy compactas la aplicación del teléfono funciona muy bien y de momento la batería funciona genial. No sé qué pasará en el futuro

Order WTUS21606
I received a broken battery. The battery is 2.5kw 51.2V. It only allows to be charged but it doesnt allow discharge.The discharge button in the app doesnt turn on, the battery doesnt allow to be restarted. Nothing works.Its been 3 days since i contacted customer support and they have been asking me for videos wich i sent and the reply was very basic instructions that didnt solve the issue with the battery. Im claiming a full refund and they continue to give no sense instructions that dont work because of course the unit is bad probably the bms is deffective or whatever.I demand a full refund inmediately and if you want your deffective unit send a prepaid shipping label to send you back the battery

It does exactly what it's advertised to do. Be sure to use a 51.2V LiFePO4 (LFP) battery with this. Fully charge & discharge the power station with battery attached to see the full combined capacity.
