I was looking for a 48V battery for my DIY off-grid system and decided to go with the WattCycle V2.5 100Ah rack battery. The 3U design makes it a good fit for a rack cabinet, and having both the app and the LCD screen for monitoring is a nice bonus. I also like that I can expand the battery bank later instead of having to replace the whole setup. For anyone putting together a similar system, I'd recommend checking the inverter compatibility and planning the rack space before ordering.
What impressed me most when I first read about Wattcycle was the price. It was reasonable and affordable compared to competitors. I purchased the 5120 watt unit and the adapter plug to use with my existing Delta 3 plus (with extra 1000w battery) 2000w total which cost almost $600 dollars more than the one 5000w wattcycle battery. It worked flawlessly as an extra battery capacity. I have recently purchased a Delta 3 Pro and added wattcycle battery as an extra battery capacity (more wattage)rather than a Delta extra battery saving quit a bit of money. I planned to purchase another which will extend my storage to 10KW plus 4KW with Delta unit.
These two WattCycle 48V 100Ah server rack batteries, featuring Bluetooth monitoring and active balancing, have been a great addition to my off-grid setup. Paired with two EcoFlow DELTA 3 Plus units, they help create a flexible home power solution that gives me more energy storage capacity and greater flexibility for off-grid living. The combination works well for my setup, and I appreciate being able to monitor the batteries through Bluetooth. Overall, they’ve helped bring my off-grid power system together nicely.
I recieved this battery a couple weeks ago and I am in the process of putting together an off-grid system now. I mounted the victron gear yesterday including a 48v Victron 3000va multiplus. Etc and a cerbo GX. So I will soon be able to monitor this battery closely. I will keep in touch with my findings. I’m about to go purchase 3 solar panels for the system.

The Evidence score uses the priorities you choose. It counts published documents, such as certificates and warranty terms, and it compares a documented figure with the best documented figure of the same kind. It does not count owner reviews, and it is not a verdict on product quality or on how many people have reviewed it. A low score can mean little is documented, or that a documented figure is below the best of its kind. Undisclosed data scores 0.
Missing for this product: Certificates evidence needed; Warranty energy disclosure evidence needed; Cell model disclosure evidence needed.

The warranty term and the lifetime energy are each scored against the best documented value for a home storage battery: a value earns its share of that best, times the weight. A documented value always earns points; an undisclosed one earns 0.
