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.

Use to charge Wattcycle 280. Charges in reasonable time.Helpful display to match my Victron shunt and Bluetooth from battery. Added inline heavy duty on/off power switch to better control charging cycle.

Came on time as expected

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!!

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

This company has great batteries and customer service. I purchased 2 280ah mini batteries. Quick shipping too. I will be buying another battery really soon.

This is my second Wattcycle battery for my Ham Radio setups. Superb performance for both the 100ah and the 20ah. I have been very impressed with Wattcycle鈥檚 product, and their customer service, which has been very responsive.

I bought 1 of these batteries and a 4 bank charger to swap out my battery that runs my electronics, pumps and lights on my bass boat. I removed 2 AGM 100 AH batteries and put a single 100 AH lithium goin in their place. I made 2 trips to the lake and I was so happy with it I ordered 3 more to replace my tyrolliny batteries. I鈥檓 running 4 of them and I鈥檝e been very happy with them. Not only do they provide nice voltage, but they charge fast and they鈥檙e really light weight. I took out 5 traditional batteries and replaced them with these 4 lithiums and got more power and eliminated 260 pounds from the back of my boat. The boat handles better than it ever has and hops on pad really quick. I highly recommend these for your bass boat or anything else.

I needed an affordable large amp hour battery in a small package. The 12V 280Ah Wattcycle Mini was the right match. This battery went in to a tight fitting Airstream Basecamp 20X trailer battery space. I did not need to make any modifications. I installed it with no issue and put a fuse in place to protect the electrical system. On three-night winter trip in the Oregon Cascades and with temperatures well below freezing, the battery easily was up to all the tasks: propane heater fans, roof vent fan, lights, 12v fridge and device charging. (I am also happy about having low temperature protection for the battery). The 300w solar panels were shaded by clouds much of the time. Thankfully, on this batteries maiden voyage it performed perfectly. Having had battery power anxiety so many times when traveling, it was great to spend more time enjoying the adventure travel experience without sweating about the battery. My next battery related purchase with be the Wattcycle 60amp charger for those rare time I want to fast charge the Mini from an outlet. For now, I look forward to many, many years of service from the battery.

I鈥檝e been using the WattCycle 12V 280Ah MINI LiFePO4 battery for my off-grid cabin, and I am extremely impressed. The battery holds a charge well and lasts throughout the day with all my appliances running. It's a compact design with high capacity, which is exactly what I needed. Highly recommend it for anyone looking to power their off-grid systems!

I purchased the WattCycle 12V 280Ah MINI LiFePO4 battery for my solar power system. It has significantly improved the efficiency of my setup. The battery provides steady and reliable power even on cloudy days. It's easy to install and manage, and I love how compact and lightweight it is compared to other lead-acid batteries I鈥檝e used.

A good product, I'm getting another one.
This battery last me eight or nine days before recharging.

My WattCycle battery arrived with the top cover opened, likely due to rough handling during shipping. I contacted their support team, and they were incredibly responsive. They offered a refund or a replacement, and I chose the latter. The new battery arrived in perfect condition, and it鈥檚 been performing flawlessly for weeks now. Great service and a great product!

EVE cells deliver outstanding energy density. Lightweight and easy to handle. The overcurrent protection works great.
