      Works like brand new

      So far so good. This one works just as well as a brand new one, and showed no signs of wear when I received it. Obviously, only time will tell if it holds up to as many charge cycles as a new one, but I am totally satisfied at this time. Only wish that there were more of these "Like New" ones available at this great price!

      Easy to use Bluetooth battery

      This battery is easy to use and out performs. Great battery

      Judge.me YouTube video placeholder

      Delivered as promised and in good packing condition. I can't install it yet because I have not yet finished the area where it will be placed in my van.

      A nice basic battery for Ham radio

      Go size and weight for Ham radio field use or emergency back-up.

      Great Power Delivery and Capacity

      I bought this battery for use with our trolling motor on our john boat. We traveled several miles full throttle (Minn Kota 50# thrust motor) running crab pots and when we got back the battery still had 60% charge remaining.

      Great battery

      Very fast service. The product came professionally boxed, and packaged very nicely. Top quality.. great price. Highly recommend.

      Trolling Motor Batteries

      Bought a set of 12 volt batteries with bluetooth for my trolling motor. Im running a motor guide 24v setup. One of the two batteries I received was dead on arrival. I notified support and within 24 hours I had a response. After. little bit of troubleshooting support decided that I needed a new battery. They provided me with a shipping label to send the old one back. I received the new battery a few days later and it is working as expected.Hopefully the batteries are as good as their support!

      We're delighted to hear that your replacement battery is working as expected and that you're satisfied with our support team's responsiveness. We strive to provide excellent customer service and ensure our customers are happy with their Wattcycle products. We appreciate you taking the time to share your positive experience. We hope you enjoy your new batteries and wish you many successful fishing trips!

      Great battery in small package, tons of available power!

      VERY IMPRESSED so far! I ordered 2 of the NEW 300 amp hour MINI lithium batteries, and they are working perfectly. I ordered them Friday, October 18th, 2024 and received them both on October 25, 2024 in perfect working order. I started off by testing 1 quickly then placing it in a freezer set to 26 degrees Fahrenheit to test the low temperature charging protection, left it in for about 12 hours and hooked to a charger and it would not allow a charge to pass! I allowed it to warm up slowing and then tested again and it then would allow charging again. Very happy to see this feature working! Being able to use my system in freezing conditions is very important to me and this helps to know my investment in these batteries will be protected!

      The second battery I began charging up off my 1000 watts of solar panels and Victron charge controllers I have in/on my fully converted cargo trailer camper. I use it as an "off-grid baby camper" as I call it. We use the camper (I built in spring 2020) for family trips, camp outs, cross country road trips, and "deer camp" where we expect it to deliver all the comforts of home in a small package while going wherever we want. We depend on the solar and lithium batteries along with chargers and inverter to keep the food in the fridge cold, my family and pets cool in the air conditioning in the heat of summertime, electric heaters and diesel heaters keeping us warm in the winter. Along with being able to run a coffee maker in the morning or making microwave popcorn for watching a movie on the TV before bed.... all while being able to camp anywhere we want without the concern of pluging in at a campsite or having to listen to a noisy and stinky generator. So far the available power in these batteries compared to my previous lithium battery bank I can instantly tell these batteries will be a major upgrade to my system.

      My previous system consisted of 465 amp hours of lithium-ion in 3 parallel batteries. Connected in my system with a 12v Giandel 2200/4000 watt inverter it powered all our needs but I noticed a slight delay in developing power on some higher demanding appliances. With my limited time with these new Wattcycle 300ah Mini's, I've so far hooked up some power tools in my garage and a microwave in my trailer and they all have preformed like they were plugged into a regular outlet in my house. That's with only 1 battery hooked up! I've already been so impressed I've purchased a third to make my system 900ah!

      The compact size of these 300ah Mini's is remarkable! Each of them is about the size of my previous 160ah lithium-ion batteries. I am going to be able to double my total power in the same space. They do weigh more (about 57 pounds each) than my previous batteries, but that is to be expected with their higher density..... or whatever they've done to pack so much power into such a small battery.

      durable

      Durability, tested and proven

      Judge.me YouTube video placeholder

      Very easy to use, very competitive price. Seems to charge very well!

      Great no-frills charger

      Gets the job done

      This battery is not only durable but also very well designed. After using it several times, I can say the power is consistent and much better than my old lead-acid batteries. The Bluetooth feature makes monitoring the battery status much simpler, and the waterproof feature is great too. Overall, it’s a purchase well worth the money, and I’ll be buying again!

      WattCycle’s lithium battery is incredibly powerful, lightweight, and long-lasting. I love its fast charging feature, which makes it super convenient to use. With Bluetooth monitoring, I can check the remaining battery life anytime on my phone, which gives me peace of mind during long fishing trips. I’m very satisfied with this purchase!

      Works like brand new

      So far so good. This one works just as well as a brand new one, and showed no signs of wear when I received it. Obviously, only time will tell if it holds up to as many charge cycles as a new one, but I am totally satisfied at this time. Only wish that there were more of these "Like New" ones available at this great price!

      suprisingly good

      Overall this is a good quality charger that is cut and dry to use. If i could change 1 thing, i would install an on/off switch so im not having to unplug it as i hook it up to another battery.

      This lithium battery has completely changed my trolling motor experience. The built-in Bluetooth feature is super convenient, allowing me to check the battery status anytime and avoid unexpected power outages. The battery life is impressive and easily lasts through a full day of fishing. I would definitely recommend it to any anglers who need a reliable power source!

      Great charger for my 12 volt lithium batteries

      I am amazed at how much more quickly this charges my Wattcycle 100 Ah batteries compared to my other Duracell and Noco Genius chargers. It works great to charge them individually as well as when I have 4 in parallel for my 2000 watt inverter. Even on the lithium settings with those other chargers, they never seemed to be able to get the battery fully charged before shutting down and acting like the charge was complete. Having the bluetooth variety of these Wattcycle batteries let me know that they weren't fully charged. Now I know the Wattcycle charger is working great to fully charge these batteries.

      Extended Range and Renewed Freedom for My Mobility Scooter

      I recently upgraded my mobility scooter's battery to the WattCycle 12V 200AH LiFePO4 battery, and it has been a game-changer. My old lead-acid battery was heavy, bulky, and offered limited range. This WattCycle battery is significantly lighter, which makes maneuvering my scooter much easier. But the real benefit is the incredible range. I can now travel much farther on a single charge, giving me the freedom to explore places I couldn't reach before. I no longer have to constantly worry about running out of power. The battery also charges quickly, which is a huge plus. The installation was straightforward, and the build quality of the battery seems excellent. It's a bit of an investment, but the improved performance, extended range, and peace of mind are well worth the price. Highly recommended for anyone looking to upgrade their mobility scooter's battery!

      Reliable Powerhouse for My Off-Grid Water Pump

      This battery provides an enormous amount of power, allowing us to run our pump consistently without worrying about depleting the battery. We've seen a significant increase in the pump's runtime compared to our old lead-acid batteries. What a difference!

      Great value

      I upgraded from one 100ah more expensive brand to two of the Watt Cycle because the one would not make it thru the night. We have used them twice now and they have exceeded our expectations.

      Happy Camper

      This is my second 100Ah Lifepo4 battery from WattCycle, and I am truly smitten with this product. I have made a transformation in my campervan, shifting from relying on traditional SLAB batteries to lithium ones. Undeniably, lithium batteries are far more efficient and astonishingly easy to use.

      Impressive Performance and Runtime

      I've been using this lithium battery with my trolling motor, and it’s fantastic! The battery lasts all day, even when running at higher speeds. It’s lightweight and charges quickly. No more worrying about power loss in the middle of my fishing trips. Highly recommend!

       Doing what it’s supposed to do.

      This battery is great so far. It is providing the power I need with power to spare. As I expand my capabilities I might add 1 more with an inverter.

      So far, so good

      I have 2 of the 200 Ah batteries plus and they are working great. I highly recommend
