It has been in operation now for 6 days.
We are happy with this product.
We are suppliers and installers of off-grid solar systems and Wattcycle is now on our supplier list.
We just bought a second battery!

New to Li and solar controllers. 67yo retired tradesman so not afraid of installations as a whole. The app was painless to work with for me. Installed in an aluminum truck tool box and at 25' away I have Bluetooth connectivity. So far no problems with cell balances. I will consider buying a second.

Still waiting to try it out all charged and the app hooked up seamlessly. Like the weight much lighter than a comparable lead acid battery

⭐⭐⭐⭐⭐ Reliable Power and Smart Monitoring – Perfect for Trolling Motors!
I've been using the Wattcycle 12V 100Ah TM Battery with Bluetooth on my trolling motor setup, and it's been an outstanding upgrade. The power delivery is consistent, even during long days on the water. No unexpected drop-offs or performance issues—just solid, reliable output.
The built-in Bluetooth monitoring is a huge plus. I love being able to check the battery's status right from my phone—voltage, temperature, state of charge, and more. It gives me full confidence while out fishing, knowing exactly how much battery I have left at all times.
The battery is lightweight, charges fast, and feels built to last. It’s clear Wattcycle put serious thought into both performance and convenience.
Highly recommended for anyone needing a dependable and smart battery for trolling motors!

Purchased 2 314AH smart mini so far so good. Did a 150Amp draw down to 58% SOC after 3 hours, ran out of time to take it longer, this test exceeded expectations. Look forward to testing it when traveling next week.

I purchased this battery primarily to replace the heavy 100A.Hr deep cycle lead acid battery that I use for my trolling motor, and secondly as an increase of capacity to my 2000 watt "solar generator" (portable back up power supply).
I did a brief test with the battery in both applications and it performed exactly as expected. On the surface it appears to be sturdy, attractive and well made. The weight makes it easy to move and so far, I am very satisfied with my purchase. My only regret is not spending a few dollars more on the unit with bluetooth communication.

Just got my order of 2-100amp batteries to power my 24v 78 lbs thrust outboard. Can't wait to get on the water. Bluetooth works greatand the reason I chose these.

I'm happy that your batteries are now available in Canada. Wattcycle is the ones I wanted after looking for quality at a good price. I made a short video on YouTube showing off my new batteries. I want to buy 2 more 100ah batteries in the near future to complete my little portable power station. I'll be making a video about that also. Thanks for putting out a good product.
Bill Prowse is the best source on Youtube when it comes to analyzing anything to do with Lithium batteries, not to mention solar power systems. His review of the Watt Cycle 12 volt LiFePo4 battery was strongly positive. I've been using it now for a few weeks and feel confident that it was a great purchase and it should provide years of reliable service.
I needed to upgrade from my heavy and low capacity Lead Acid RV batteries.
After some YouTube research and on-line shopping, I came to the conclusion the WattCycle Group 24 100 AH battery was the best combination of performance, user ratings and price. For me this is a very good value.
A small customer service issue was dealt with and resolved quickly. The batteries were shipped quickly. Thank you.
I finally made the move to LiFePO4 batteries in my RV. The original Lead Acid worked but were lacking in usable capacity, and were heavy.
After a bit of YouTube research and on-line shopping, I chose the WattCycle. It's a very good battery, with very good on-line reviews, good tested performance and overall for me results in a battery with very good value.
With this kind of investment I knew the best thing would be a LiFePO4 specific charger. This one was made by WattCycle specific for the Batteries I bought. With a package deal (with the Batteries I brought) the pricing was perfect. It charged the batteries quickly and was relatively quiet.
Shipping was fast. Thank you.
