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.

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!

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

Fantastic so far!!!

Hope this holds up. Bought three for 36v trolling motor, reduced weight by 81 lbs. Massive difference. Love them so far. If they last 2-3 years, it's a win. Company is super responsive and checks on product.

Perfect!!

I fish a lot of electric only reservoirs. I am so proud & happy to take 3 HEAVY AGM batteries out of my boat. Thank you WattCycle!

Trolling battery

This is a great product I use it for trolling with a 55 pound thrust trolling motor. Works great troll for 3 hours at 50% speed and the battery still was above 50% reserve, awesome.

Great battery

Unbelievable weight diffence from lead acid AGM batteries. No power difference after running a 24v Ultrex for 2 days under average conditions. Amazing

So far, so good

It was delivered a day early and packaged well. I fully charged it and hooked it up to my setpower pt55 just to see how long it will run it. So far 61 hours and counting. I can't compare it to anything but so fat 5 stars

Well designed, looks good too.

This battery seems to be of quality materials and construction. It holds a charge well and retains amps as to be expected under normal use loads. I purchased it to hold one of the batteries on my boat and it is performing excellently.I have been very happy with these batteries.

Great battery

Totally awesome we used deep cycle batteries on our 24 volt minn kota trolling motor and after 4 hours of constant trolling the batteries were completely dead, with the WattCycle 24 volt lithium ion batteries we trolled constantly for 5 hours and worked well.

New lithium 12v 100ah battery.

This battery has met my expectations. It's easy to hook up and has plenty of power for my 55-pound trolling motor. The battery has lasted me for 8 hours with no problem. Only time will tell how it holds up as it has only been used a few times. I am a weekend angler.
