Got my bluetooth version

I just installed my mini battery system. Control the battery at my fingertips achieved. It’s very smart…

Life two with one hand!

Just installed the two 100ah batteries in our Winnebago. They mount on a plate that sits underneath the chassis. Last pair of deep cycle AGM batteries had to be raised into place with a motorcycle jack. This time I lifted the back side and slid it on the plate and just lifted the other end with one arm. TOTALLY AMAZING!

It matches my 100ah battery! 5 hours fully charged, thanks wattcycle

Incredible Cycle Duration and Versatility for Various Applications

In the video, I am running a 8 kW diesel heater. I had it running previously for about five hours. The battery has not dropped at all voltage the battery charger I have plugged into the battery, but not plugged into the wall. I have monitoring the voltage to the charger it says 100% and at 13 V. The cycle duration of this battery is incredible and I highly recommend it to anybody that would like to use it for RV camping boating and what I use it for a garage heating. Also would be great for a solar system.

Consistent Performance for My Trolling Motor!

this is the 3rd one I have bought. I put 2 in my boat for my minn-kota trolling motor. works great used 3-4 days and battery shows 100% charge.

Hoping for Longevity, Excellent Pricing!

I hope I get good long use of this battery the pricing was good better than most other brands offered.

Reliable Power for My Portable Refrigerator!

This the second of two batteries I have bought and please with both of them same brand and capacity 100 amp hour these are good batteries and I am very satisfied with their output and what appears to be good quality in the construction of this battery it is very compact and lightweight and will run my little portable refrigerator in the car for about 4 days before needing to be recharged.

Received a replacement with in a week

Battery arrived I checked voltage when I opened the box it is zero. Reached out and they have shipped a replacement battery. Received new battery it works great they included a charger. Nice when companies stand behind their product. I will buy from them again because they stand behind their product.

I have yet to use the battery, so I can’t give a product review. However, the shipping was fast and very well packaged. I will order this battery from the same seller again if the need arises!

Early Delivery, Excited to Install in Kayak!

was delivered sooner than expected, have not installed in my kayak yet but it's everything I expected and can't wait till I get all my electronics connected.

It seems to work fine

Left the battery intact B M S seems to be O K.

Works very well!!!

I ran mine for over 3 hours today clearing out a tough field and it still had over 50% left. If you do the conversion be aware that other batteries have built in management systems that require more modification to the mower. These batteries did not require any changes.

Good product for grate price

Lead is dead this is the best upgrade iv made for solar

Has the power.

Delivered 2 days ahead of time. Charged all the way up and has been holding 100 percent for a week now. Seems to be a great battery. Put it in class C motor home under the steps replacing 2 wet cell batteries. Great fit.

Lightweight and Easy Setup for Off-Grid Power!

Building a small off grid power supply, and these batteries are lightweight and easy to set up!

First battery as DOA Replacement was shipped and all is good

I have a total of 6 Wattcycle batteries. 4 group 24 and 2 of the Mini.
1 of the mini batteries was DOA, 0.15 vdc. It would not take a charge.
I contacted the seller and he had me try to wake up the BMS by putting 14.6 vdc to the battery.
I tried and the unit would not wake up. Sent him the information on the test and he had a replacement for the DOA unit shipped to me.
The replacement arrived and shipping voltage was 13.18 vdc. It's currently on the charger. Everything looks good.

Great value

Great value, perfect group 24 fit. My only offer for improvement would be to in include or offer longer bolts for the terminals. When running parallel you have to put more than one lug together, sometimes three.

Hi Mike,

Thank you so much for your positive review!We are delighted to hear that you find our 12V 100Ah LiFePO4 battery to be of great value and a perfect fit for your Group 24 application. Your satisfaction is our top priority, and we appreciate your feedback on the terminal bolts.

We understand the importance of having appropriate bolt lengths, especially when running batteries in parallel and needing to connect multiple lugs. To address this, we currently offer two lengths of M8 terminal bolts:12mm and 14mm.

These options should accommodate various setups and ensure secure connections for your application.

Your suggestion for improvement is invaluable, and we will continue to consider customer feedback to enhance our products and services.Thank you once again for your kind words and support!
