Let customers speak for us
I needed longer battery life, my old 100ah battery just wasn’t cutting it. With this battery I can run my fridge/freezer 3 times longer without worrying about running low on battery life.
This harness takes all the guess work out of linking your batteries in a series. Just connect all the wires up and plug the ends in and it’s done. They also come with really nice heat shrink connectors to hook up to your main power wires. 100% a must have for a 36v system.
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.
This charger is an absolute BEAST!! By far the best 4 bank charger I've ever owned. I've been running it for about 6-8 months and its performed flawlessly!! Guys If you're not familiar with what I do, check out my socials and you'll see me put everything I own to hard work! I am rough on my stuff! I buy it to use it and I don't care about a scratch, ding, or dent. I put my boat and all my equipment through the ringer every time I go out. WattCycle makes QUALITY products at an incredibly low price! https://www.facebook.com/JoelDavisFishing
Very well constructed, packaged, and documented battery.
Just want to Maggie's service is excellent 👌 from start to finish she walk me through the entire process to get my battery and I am so happy with my 8 battery received in perfect condition communication with Maggie's is excellent reach out to her for support 👍
Couldn't be any happier I bought 3 100ah Pro trolling motor batteries and a 4 bank Charger Works Great
I received this 12V 280ah Smart Edition Bluetooth Mini with 200ah BMS the other day. I want to run my 12,000 Btu mini split overnight in my RV, so I tried running the 12,000 Btu mini in my garage which over 500 square feet more area to cool.
So I connected this WattCycle 12V battery to an inexpensive 12V dc to 120V ac pure sign wave inverters. I plugged in my mini split at 5pm, ran over night till 9 am. The mini split was still running with 36 percent state of charge left in the battery.
This was AMAZING! I plan on getting another 12V 280ah so I can run all my appliances in my 23 foot RV.
I highly recommend this battery. The phone app is great & only took 2 minutes to download, go through promos & recognize the battery. I can make setting changes on the phone app. Now I will order their WattCycle 30A charge controller to use solar to run appliances & charge battery during the day.
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.
VERY IMPRESSED so far! I ordered 2 of the NEW 300 amp hour MINI lithium batteries, and they are working perfectly. I ordered them Friday, October 18th, 2024 and received them both on October 25, 2024 in perfect working order. I started off by testing 1 quickly then placing it in a freezer set to 26 degrees Fahrenheit to test the low temperature charging protection, left it in for about 12 hours and hooked to a charger and it would not allow a charge to pass! I allowed it to warm up slowing and then tested again and it then would allow charging again. Very happy to see this feature working! Being able to use my system in freezing conditions is very important to me and this helps to know my investment in these batteries will be protected!
The second battery I began charging up off my 1000 watts of solar panels and Victron charge controllers I have in/on my fully converted cargo trailer camper. I use it as an "off-grid baby camper" as I call it. We use the camper (I built in spring 2020) for family trips, camp outs, cross country road trips, and "deer camp" where we expect it to deliver all the comforts of home in a small package while going wherever we want. We depend on the solar and lithium batteries along with chargers and inverter to keep the food in the fridge cold, my family and pets cool in the air conditioning in the heat of summertime, electric heaters and diesel heaters keeping us warm in the winter. Along with being able to run a coffee maker in the morning or making microwave popcorn for watching a movie on the TV before bed.... all while being able to camp anywhere we want without the concern of pluging in at a campsite or having to listen to a noisy and stinky generator. So far the available power in these batteries compared to my previous lithium battery bank I can instantly tell these batteries will be a major upgrade to my system.
My previous system consisted of 465 amp hours of lithium-ion in 3 parallel batteries. Connected in my system with a 12v Giandel 2200/4000 watt inverter it powered all our needs but I noticed a slight delay in developing power on some higher demanding appliances. With my limited time with these new Wattcycle 300ah Mini's, I've so far hooked up some power tools in my garage and a microwave in my trailer and they all have preformed like they were plugged into a regular outlet in my house. That's with only 1 battery hooked up! I've already been so impressed I've purchased a third to make my system 900ah!
The compact size of these 300ah Mini's is remarkable! Each of them is about the size of my previous 160ah lithium-ion batteries. I am going to be able to double my total power in the same space. They do weigh more (about 57 pounds each) than my previous batteries, but that is to be expected with their higher density..... or whatever they've done to pack so much power into such a small battery.
This battery is not only durable but also very well designed. After using it several times, I can say the power is consistent and much better than my old lead-acid batteries. The Bluetooth feature makes monitoring the battery status much simpler, and the waterproof feature is great too. Overall, it’s a purchase well worth the money, and I’ll be buying again!
WattCycle’s lithium battery is incredibly powerful, lightweight, and long-lasting. I love its fast charging feature, which makes it super convenient to use. With Bluetooth monitoring, I can check the remaining battery life anytime on my phone, which gives me peace of mind during long fishing trips. I’m very satisfied with this purchase!
This lithium battery has completely changed my trolling motor experience. The built-in Bluetooth feature is super convenient, allowing me to check the battery status anytime and avoid unexpected power outages. The battery life is impressive and easily lasts through a full day of fishing. I would definitely recommend it to any anglers who need a reliable power source!
I recently upgraded my mobility scooter's battery to the WattCycle 12V 200AH LiFePO4 battery, and it has been a game-changer. My old lead-acid battery was heavy, bulky, and offered limited range. This WattCycle battery is significantly lighter, which makes maneuvering my scooter much easier. But the real benefit is the incredible range. I can now travel much farther on a single charge, giving me the freedom to explore places I couldn't reach before. I no longer have to constantly worry about running out of power. The battery also charges quickly, which is a huge plus. The installation was straightforward, and the build quality of the battery seems excellent. It's a bit of an investment, but the improved performance, extended range, and peace of mind are well worth the price. Highly recommended for anyone looking to upgrade their mobility scooter's battery!
This battery provides an enormous amount of power, allowing us to run our pump consistently without worrying about depleting the battery. We've seen a significant increase in the pump's runtime compared to our old lead-acid batteries. What a difference!
