Barramento WattCycle 250A (vermelho)

Got this WattLINK cable to connect my Ecoflow Delta 2 Max to an External 2.5 kw server rack battery and after a firmware update on the Delta 2 Max it works very well. There is a slight discrepency of charge rates (3-5% SOC difference), where the Ecoflow will charge before the external battery and the solar input reads 0 as if charging has stopped, but the server rack battery continues to charge (likely equalizing from the Ecoflow) and when it draws enough power from the D2M, the solar charging kicks back on again, maintaining the state of charge. I'll be posting a video on this awesome upgrade on my Youtube channel (http://www.youtube.com/@backtotheadk883) soon.

I bought this to upgrade from a 100ah lithium battery in my travel trailer. It more than tripled my capacity and easily fits in the factory camco double battery box with no modifications required. The price was great and I highly recommend this.

This is my second “dumb” 314Ah Mini. I was able to squeeze two of them into my 2016 Winnebago View 24G coach battery compartment with just a slight modification (removed 4 small sections of aluminum that make up the battery “box” and cut two small slits in the top in order to bend up the lip a bit). I use them to both feed the coach 12V system as well as to provide backup power to an EcoFlow Delta Pro that I use as storage/inverter/solar controller. These 3 units provide 11.6kW of storage in a compact and flexible arrangement. When boondocking I power my whole rig (30A) by connecting the shore power cable the Delta Pro and use its battery for the 110V system and the WattCycles for the 12V system. If my Delta Pro starts to run low, I can move power from the WattCycle batteries to the DeltaPro by using the EcoFlow 800W alternator charger. All of this is kept charged from the alternator using a Victron Orion XS 1400 50A DC-DC charger. Solar panels are next!

We received two 314ah batteries that had the tops popped open. Partially charged and appeared as new. Took a gamble and charged them at 50 amps with no issue. They appear as new, and I just used a marine battery strap to tie down the lid in case we ever need to do maintenance. Wrote to company and they responded with all the answers I needed. A great way to get twice the AH batteries for the same cost as 1 retail unit. Very happy with purchase and the company.

I wanted a deep cycle battery as a back up that could be attached to either my Dakota Lithium multi box or my Ancor power station. This battery not only vastly improves both but outshines them with its built in Bluetooth and great charge retention. It’s also built so per strong so I don’t need a separate case to carry it in.
I’m very happy with this purchase.

Will Prowes led me to this manufacturer and I am glad he did. After years of frustration with another manufacturer, I have a battery with plenty of capacity and the ability to see that the charging equipment I have is doing its job and how the loads in my camper draw down the stored charge.

I wanted the 314AH battery WattCycle offered and that was out of stock for a while. I entered my email and they notified me when it was available, then delivered it promptly following my order, with a promotional discount. It just fit in my camper's battery box and I followed instructions on WattCycle's web site to set up my Victron charging equipment. I am just two weeks out camping and everything is working as it should. Thanks WattCycle!

I have purchased four of these batteries and well, please with them. I have a lot of people look at my project and they love the way this Battery look and ask me How did I find this batteries and I told them I will be ordering six more of this batteries for another project that I’m working on, and I would like to take out time to thank watt cycle for their support and helping me with my project.

Works as described. Very good customer service... I ordered the eco flow adapter cable at the same time.
The battery speed a day later and arrived in very secure packaging. The adapter shipped a little later, but the responsive customer service team was able to get it shipped out quickly so I could get my battery connected to my Delta 2 and test it out. I highly recommend this to anyone with an Eco Flow Delta looking to excitable their power storage.

I replaced two FLA batteries on my sailboat with this. 1/3 the weight, 50% more usable energy, 10x the life and zero maintenance. The Bluetooth works great, but I thought the app needs a little work; it’s not intuitive what the buttons do…. Needs some online instructions. The on/off button on the battery is a great feature.

My Custom Offgrid Solar Designs Victron system is working great with my 4 WattCycle 314ah batteries. I had SOK 314ah batteries and could never get the cells to balance properly so I decided to try these and so far I have been impressed. The cell balancing is excellent! Customer support was good as well. Thanks [****]

I just received my first Wattcycle 48 volt 100 AH battery. I am using it to power my Starlink set up and charging it with two 400 wat solar panels supplemented with AC power when the Ecoflow Delta 2 internal battery runs low. The system usually lasts about half way through the night on the internal battery. Now the system runs through the night with power to spare. Just ordered the 2nd battery. Looking forward to an adapter for the Delta pro 3 next

I bought two of these to put in my RV. Just started testing them prior to installing them. I charged them both to 100%. I used a 2000W Xantrex inverter running a small electric heater for the load and a Victron shunt to measure the battery. The average current is about 120A dc when running the test. I set the inverter to shutdown at 11V so this is higher than the 10V normally used for capacity testing. Battery 1 showed 654Ah, battery 2 delivered 651Ah. I repeated the test a second time and got similar results. The battery case is steel so it seems rugged. I could barely lift the battery and I wish the handles were wider. I like that the terminals are on the end of the battery which works well for my installation.

Wattcycle is the first company to hear a need and fulfill it. I've seen him change their shipping of seeing them change their way their terminals are set up their power switch and such a short period of time so this doesn't surprise me I got one of these cables and it works perfect. Keep up the good work guys.

I needed to replace my house battery with a lithium and this 100 AH Small footprint WattCycle was the perfect find. I can operate the boat for several days without a need for a recharge. It delivers consistent and ample voltage for my needs.

I just installed 2 of these 314 Ah batteries in my RV. So far they are working fine. Once they get a real test this spring I’ll know if they are good.

Great battery!

I’ve had this battery for about a month. So far no issues. App connects and syncs up fairly well when inside my RV; standing outside seems to connect and sync better. I also appreciate the app lets you bind the battery to your phone. It works well with my solar setup and RV converter. It gives a lot of info on the app. Really appreciate that you can turn on and off either or both discharge and charge on the battery through the app. I don’t see an hardware option to do that on the battery itself but I haven’t really looked either. The option to control the battery makes it safer when needing to install or work on wiring when needed. It seems like a safe battery and does shutdown when it’s too cold for charging so I assume it does the same when too hot through its BMS. The capacity is great for my needs. It is a pretty heavy case but the handles and box that holds the battery inside is solid. I like this option because it cuts down on wiring as I had 4 12v 100ah batteries in parallel which saved wiring and space. Hope this helps anyone out. The only issue that I would consider major is that WattCycle did not fill out the proper paperwork to have it shipped to my place via fedex which it was setup for as it is lithium and needs ground transport. So fedex notified me I had to pick it up myself because according to FedEx WattCycle didn’t fill out the proper paperwork for them to continue shipping it to my home.

I would have given a 5+ except the grounding cables and the link cable lengths did not match the power jumper lengths. I measured the power cable length to determine the spacing between the batteries for max cooling. After fabricating the steel rack, the grounds were way to short and the link cable ends are pulling on each other. (Please send ground and link cables that match the power cable lengths)...
That said, the packaging of the batteries was second to none. Shipping was extra fast; they came 3 days early. They powered up and worked as they were advertised with no surprises. Thank you for a fine product at a great price.
