It arrived quickly, although I haven't used it yet, the voltage is fine, I was able to charge it. I don't know exactly what secondhand means, but it looks new from the outside. I have previously bought 2pcs 24v/100Ah batteries from them and have been using them with satisfaction for my solar system for about a year. That's why I dared to buy a battery for my small boat here.
Great service
I have an older 24 V solar array hooked to 12 V batteries. The batteries were over 10 years old and dying. I did a direct swap and they worked perfectly. I am ordering more.
Originally told battery charger was out of stock and a replacement would be sent. Then I was sent a 12v charger instead of 24v. Wattcycle has been difficult to communicate with to resolve this issue. I am still waiting. Update: I received a $100 credit for the charger which I am satisfied with. Also, I check the capacity on each of my batteries and they were excellent. Now I give 5 stars.
Happy with quality snd service

How to store the 48 volt golf cart battery?
How to store the 48 volt golf cart battery?
We recommend bringing the batteries to a 50% state of charge.Then disconnect the battery from any loads by removing the negative cable from one battery.On average, the batteries lose< 3% capacity per month at 77 F/250°C, This is subject to increase if stored in extreme environmental conditions.
Let customers speak for us
Exactly as described, includes comms cable and battery cables, screen is easy to read, appears to be accurate ah rating. Quality case. Excellent packaging (thick cardboard box with protective card edge strips with dense foam to cushion movement).
Only improvements they can make are instructions don't explain how to mount the rack and handles but does talk about not included stacking kit mounting. And the app isn't particularly well thought out. I understand it's a reskin of the BMS manufacturers app, but it could be a lot better with very little changes.
But overall 9/10, exactly what I needed at the price I needed.
I haven't had the battery long enough to see battery full potential and charging times. Soon though.
Bought this second battery to use in series with the first battery to make 24V battery bank to run my EG4 direct solar 12,000 Btu 120V ac mini split overnight. I can air condition 600 square foot area with just 2-12.8V 280ah batteries in serious. Although we did another video where we ran this mini split overnight with just one WattCycle 12.8V battery and a 120V ac output inverter Keeps area 600 sq ft area 76-78 degrees overnight even with it being 116 degrees outside yesterday. Still have 40-50 percent state of charge left in batteries in the morning when the battery bank is charged up again. I will definitely buy more WattCycle batteries. Have been using for several months now, extremely reliable for me. Highly recommend the WattCycle batteries.
Batteries arrived in good shape & well packed. Came with short & longer bolts which was helpful. I installed 4 of them in a boat as the primary house side. They replace 4 each 210 AHr AGM batteries that were half again bigger and twice as heavy (120 lbs each) as these ~60 lb 314 AHr LifePO4 batteries. This tripled my house capacity & removed 240 lbs of the weight. I added 250A MRBF Fuses to each +positive battery, as well as a 350A Class-T fuse on the overall DC+ side. Additionally, I added a Victron 500A Waterproof SmartShunt to monitor the charge/discharge levels. For charging, I added a Victron Orion XS 50A DC to DC charger for the alternator, and a 40A LifePO4 AC to DC Charger with a remotely activated plug. So far, the batteries seem to be working as advertised.
Had a few issues with shipping due the batteries being so heavy, may have been dropped by FedEx but WattCycle shipped out a replacement. Can’t fault the customer service. Just finished putting my server rack together before wiring it to the inverter.
I needed longer battery life, my old 100ah battery just wasn’t cutting it. With this battery I can run my fridge/freezer 3 times longer without worrying about running low on battery life.
This harness takes all the guess work out of linking your batteries in a series. Just connect all the wires up and plug the ends in and it’s done. They also come with really nice heat shrink connectors to hook up to your main power wires. 100% a must have for a 36v system.
Use to charge Wattcycle 280. Charges in reasonable time. Helpful display to match my Victron shunt and Bluetooth from battery. Added inline heavy duty on/off power switch to better control charging cycle.
Very well constructed, packaged, and documented battery.
