Wattcycle 12V 100Ah LiFePO4 Battery - Heavy Duty Power Backup for Solar & Home Brownout Use

I love the product so far. Would have been nice if Fedex did not drop it on its face multiple times. Service team was great and helped me resolve the issue. A+ Support Team.

I've been using this battery for 5 days now, paired with the EcoFlow Delta 3 Plus. It works flawlessly

I bought the 100 A battery and with it to supply the electric motor for my kayak and what can I say the runtime is incredible over 8 hours more than I thought and the access via Bluetooth also works great thank you again

So far so good. It needs time for proper evaluation...

Products are great but the website makes it hard to compare size and prices. You can't back track web pages to look at different products.

i had an issue with one of my batteries which had to be replaced. the support given by lyra was fantastic as it was not an easy delivery. i was in malta when this occured and heading to sicily and on to tunisia. dpd cannot deliver to any european islands or africa. eventually a contact was coming from greece so lyra managed to get the battery sent there after a lot of work. well done lyra you are a credit to wattcycle.

Mil gracias a Talia 100 estrellas

The WattCycle 12000 Super is a capable 12kW split-phase all-in-one inverter with a standout 200A bypass, dual MPPTs rated for up to 24kW of PV, and strong 250A hybrid charging that exceeded expectations once running, handling real loads, surge, and whole-home scenarios better than anticipated. That said, the learning curve is kinda steep thanks to a mediocre manual with unclear or incomplete guidance on settings like neutral-ground bonding and priorities, and the included Solarman app plus Wi-Fi dongle is pretty bad—flaky connectivity, limited usability, and extremely slow update speed that make monitoring frustrating. Getting it talking cleanly to Solar Assistant was also a tough process with workarounds needed rather than plug-and-play support. Overall it’s a solid hardware performer for the money if you’re comfortable digging into forums and videos, but the documentation and monitoring ecosystem hold it back from being truly hassle-free. If you are just looking for the ultimate all in one inverter with a 200a bypass this is definitely it.

DE accu is perfect doch de 12Volt lader is een probleem gevalletje.
De ventilator maakt te veel geluid in de wagen.

I would like the app to be more comprehensive, with more information on the status of the cells.

5 star

The 48V 100AH Server Rack battery performs exactly as advertised and the Ecoflow adapter cord works well also. Love the product so far. But it is very heavy, at over 90 Lbs.

fast delivery, great product

Gastei

will not charge!

I don't normally do reviews or surveys. I'm doing this one because I have a mixed opinion.
I received some assistance fairly quickly VIA email, but called with a question when installing my batteries and never received any response to my message. I had a concern about how I was connecting them, and worried that I could damage the batteries or cause other problems. Fortunately, neither came to fruition.

I had to be neutral on this since I have not used the battery yet. The one thing I was not expecting was how difficult it was to move around. At nearly 100 pounds with no handles - it is virtually impossible to lift and place on the bottom of a 2 shelf mobile cart. I'm going to have to unbolt the top shelf and remove it in order to have any chance of lifting it onto the bottom shelf. Trying to find straps to place under it so I can lift it up.

Quite happy.

It was nice being able to see the charging statistics and verify my RV charging system was working and how many amps were being fed to the battery when charging from the generator, or the shore power, or from the Alternator while driving. I feel more comfortable with the switch from lead-acid to LiFePO4

Customer service is awful. Sent me the wrong battery. Then wouldn't send the right one until I sent the old one back. They said they would do a cross shipment so I would recieve my battery faster. I've been without power for 3 weeks now. This company sucks and so does their customer service. I will never buy another battery from them again. Ill be switching to eg4 batteries. DO NOT BUY FROM THEM. THEY DO NOT GIVE A SINGLE SHIT ABOUT YOU OR YOUR SITUATION. Absolute shit company. I still dont have my new battery.

I’ve used this battery in conjunction with a delta 3 for about a month and while it charges through the inverter, they never match charge levels or even come close. In the morning after an evening of discharge, the delta 3 will show around 64% and the battery shows around 94%. For test purposes I set max discharge to 30% and it shut off at 30% as expected but there was more than 70% left on the watt cycle. While it does seem to last longer with the watt cycle, it will still run out of power when there’s plenty of battery left. Not sure if the issue is in my settings or if this is just how it works.

The package was shipped and received well. I noticed I was missing some of the bolts and contacted customer service who helped me out in a timely manner. I would certainly buy again if I needed more batteries.

Couldnt be happier with this battery . Was previously using a lead acid leisure battery and getting no more than a days fishing and that is flyfishing so alot of start / stop and mostly lower gears . Now though after putting the new watt battery to the test i cant believe the difference , ive even added a few hours of trolling to the mix and i got four days fishing with 22% life still to go. We even had a wake behind the boat at full speed which i never remember seeing with this motor . The motor is a minnkota endura 50lb and at least 15 year old . The old leisure battery was over 5 years old but like i said i dont ever remember the motor having that much power . So to sum it up im absolutly delighted with my purchase which i pondered over for far too long
The blutooth is something every battery going forward should have , gives you prfect cotroll over your consumption for the following days fishing . Happy days now i just have to start catching

Good price. One side of the battery is not flat. Let's hope it is manufacturing and not old cell.

Never received the advertised monitor. Emailed support about the monitor and ecoflow adapter, was told they'd be coming in separate packages. The ecoflow adapter showed up, the monitor didn't. Battery works, but I really wish they would just send what I paid for. I could've ordered something similar from Temu for half the price.... and I've had success with Temu batteries.
