So far it has charged all my batteries as it is supposed to. Easy install and smaller than my minn kota.
Couldn't be any happier I bought 3 100ah Pro trolling motor batteries and a 4 bank Charger Works Great
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!
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’s made in China
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.
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.
Bought this to replace the FLA battery on my travel trailer. So far, it's been pretty good. I added some foam pieces to my battery box to keep it from sliding around too much, since this battery is considerably smaller than the old battery.
Test run:
I haven't done any trips yet but so far, I've used it overnight to run the lights, 12V fridge and the fans for the heating system in 35-degree weather, and charge a few devices in the trailer as a test. It went from 91% down to just about 50% charge and the voltage was still around 13V the following morning. It also charged back up pretty nicely the next day to about 89%, even with fridge and some lights still running. (For reference, I have a 165W solar panel and it was a partially cloudy day with occasional tree shadows).
Bluetooth App:
The app is handy and I like that I can shut off charging and discharging. It would be nice to set charge and discharge limits as a percentage of remaining capacity, but you can do it based on voltage so not a huge deal.
Overall, I'm happy with it so far. I'm considering ordering a second one to expand my capacity.
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’s product, and their customer service, which has been very responsive.
The items that was ordered are exceptional, great fit for my boat.
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’m running 4 of them and I’ve been very happy with them. Not only do they provide nice voltage, but they charge fast and they’re 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’ve had this charger just over a month now, it is above and beyond what I expected. It’s lightweight and compact compared to other 4 bank chargers. It charges my watt cycle batteries fast and keeps them healthy and charged. And you CANT beat the price anywhere
Works great, good price, and the compact size is perfect for mounting in my boat.
Only reason it doesn't get five stars from me is I have an older Android 7 phone (Nexus 6) which is not supported by the BMS Meta app. I was able to get it working on a Kindle fire 7" by using a free app called Fake GPS. This was only possible after "jailbreaking" the Kindle and enabling google play store (a technical process which is difficult for many). If you have an obsolete phone this may be an issue for you and I did not feel like I should have to purchase a whole new phone just to watch the battery's behavior. I purchased after watching teardown videos on youtube to confirm build quality and safety features. Really, this is a five star battery for anyone not using an obsolete phone. After a few weeks, I liked it enough to buy a second unit and hooked them up in parallel for 200 amp hours.
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’ve been very pleased with the product and would definitely recommend
Came packaged nicely no issues. Nice they included both bolt sizes if you have two cables on the terminals. Put two of them in my rv and have worked great so far. Would love to get a bigger charger. Maybe one day.
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’ve used.
I’ve 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!
Battery is nice but the BMS Meta app quit working just a few days ago. I don't understand why it requires a connection to a Chinese server when it only needs local Bluetooth access. Please fix the app.
I just ordered a WattCycle 12V 300Ah MINI LiFePO4 Battery. But I was worried after seeing many people complain about the top cover. It happened that WattCycle launched the Bluetooth model. After negotiation, I changed to the Bluetooth model of 12V 280Ah MINI. At the same time, the $50 discount originally for the 12V 300Ah MINI was transferred to my Bluetooth model. I am very grateful to WattCycle. After understanding my concerns, WattCycle promised me that if the top cover falls off, they will refund me or reissue it. I am looking forward to my Bluetooth model.
