Doesn't seem to hold a charge.

We are sorry that you faced this issues, please contact us via service email asap.

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!

We're so glad to hear that the battery is performing just like new and that you're satisfied with your purchase. We understand the appeal of the 'Like New' options, and we'll certainly take your suggestion into consideration as we continue to offer quality products at great prices.

Struggling to get support

The first time I used it, after charging for a few hours it started cycling on and off every few minutes with the voltage on the battery increasing. When it hit 14.8V I unplugged it since that seemed beyond the battery specs.

I asked WattCycle support if that was normal and the reply I got was “ We recommend that you can stop charging before it full charged, which can avoid such situation.”. I already have a lead acid charger which can partially charge my lithium batteries - I bought this charger so I can fully charge them when needed

So, I still do not know if the charger is functioning correctly or not. I would love to change my review if can get a satisfactory answer from WattCycle, but right now I am not happy with this purchase. (WattCycle are you reading these reviews? If so, I would love to be contacted to discuss this further so I can understand if this is normal behavior or if the charger has a problem.)

Absolutely love these batteries. I already had 3 of the 12v 100Ah for my Ranger Z520 and when I bought my Clubcar I knew I was going with the 12v 50Ah. I dropped 320lbs off my golf cart and I used to have to charge the lead acid batteries every day just to get around my neighborhood. So far the first charge on the WattCycle 12v 50Ah has lasted 4 days!!! I am extremely satisfied with my purchase!!!!

Runs hot

Can't beat the price and it's compact but it runs hot. The surface is smooth plastic without vents or fins. Maybe it is fine running hot. I would make sure that as much surface as possible is exposed.

4 bank charger

So far so good

Great battery at a great price

Very well constructed, packaged, and documented battery.

Battery

These batteries are so lite compared to my acid battery,and the trolling motor I can run so much longer and still have enough battery left to fish another day.wow nice😊

Seem to work well

I bought these for a rv to replace lead batteries. Pleased so far. Good reserve power now. App is a plus.

Much small and more powerful battery

Wattcycle battery with small size and double power. I have test it on my boat, it is much better than old style battery; the charge time is much quick than the old lead battery. Even only having for one week but I love it.

Great product for the price

So far it has charged all my batteries as it is supposed to. Easy install and smaller than my minn kota.

Smashing Smallmouth Bass

Couldn't be any happier I bought 3 100ah Pro trolling motor batteries and a 4 bank Charger Works Great

Came on time as expected

Great battery and excellent service!

Batteries received quickly and well packaged. Watt Cycle honored a price drop the day after I ordered without hesitation. Communication has been excellent. I requested information regarding the batteries to program my charger isn’t it was answered promptly.
The batteries are great looking and up to this point perform well. I’m very pleased with my purchase!

Worked well.

I purchased this charger to fully charge my 3 new 12v 100ah batteries before hooking them up in series for my golf cart. Did the job quickly.
Now I have the 36v charger installed that is also working very well.
Batteries have performed well for the 2 weeks they have been in the cart. Less weight, a tad bit faster and longer run time.
Happy so far!!

I’ve purchased. 12v 20ah and a 12v 100ah.Incredible price.US soon.

Purchased 12v 20 ah and 100ah batteries with BMS. Incredible price. Only negative is it’s made in China

I would buy again...in 10 years.

I have purchased at least 4 of these batteries as storage for the 30KW whole-house solar system that I am building and have not had any issues with any of them. I thank Will Prowse for reviewing these batteries on YouTube, which has given me confidence that I had made a great purchase!

Great battery

Works great in a DIY solar power box I built.

Great battery and great customer service.

We've all been seeing the reviews on YouTube. Well, they are correct, the battery is everything it's cracked up to be. I have purchased 3 Minis so far. I had a question about one and got a response back in less than 24 hours.
This battery is a great product at an unbelievable price. The Bluetooth model is well worth the money.
Thanks for the great customer service.

thanks

thanks

Awesome

This charger charges extremely fast. I use it on my two Watt Cylce 100 watt batteries in parallel. I have even used it to charge my batteries while plugged into my 3500 watt generator and it works perfect.

very good unit

This battery works very well for what I need it for, I just ordered another one.

Great customer service

Ordered 8 of these and was very impressed by the quality. Once I was ready to put them into service I found one battery that would not communicate via bluetooth. Contacted the seller and in short order they sent me a replacement . Excellent customer service.

I LIKE THE BLUETOOTH

Furnace Power Backup

I used this battery with an inverter for furnace power backup and testing shows I can get 7-8 hours on very cold days. The battery easily meets it's AH rating and the Bluetooth functionality is great.
