Yes. Two identical 12V LiFePO4 batteries can be connected in series to create a 24V battery system.
With integrated Bluetooth 5.0 connectivity and real-time status monitoring, you can easily track voltage, charge levels, and overall health via our dedicated mobile app. Please read the WattCycle detailed Bluetooth Guide.
We recommend charging the battery fully with a compatible LiFePO4 charger before its initial use and maintaining a 30%–50% charge for long-term storage to ensure optimal performance.
Yes. The battery features an IP67 waterproof rating and rugged construction designed for harsh marine environments.
Our advanced BMS continuously monitors the current flow and instantly disconnects power if it detects an overload, ensuring that neither the battery nor your devices are exposed to harmful currents.
This proactive overcurrent protection automatically resets once safe conditions resume, maintaining optimal performance and extending the battery’s lifespan.
In most trolling motor applications LiFePO4 lithium batteries offer clear advantages over lead acid. They are lighter, deliver a higher usable energy percentage, charge faster, and provide a much longer cycle life with less maintenance. The trade offs are higher upfront cost and the need to use LiFePO4 compatible chargers or charging profiles.
Yes, a 12.8V 100Ah LiFePO4 battery can run a 55lb trolling motor, provided the battery and wiring can handle the motor's continuous current draw. Example calculation: 12.8V × 100Ah = 1,280 Wh. A 55lb motor drawing about 40 A uses roughly 12V × 40A = 480 W, so estimated runtime = 1,280 Wh ÷ 480 W ≈ 2.8 hours. Real runtime depends on propeller, boat load, speed setting, and environmental conditions.
"Marine battery" is a broad term that can include starting batteries, deep cycle batteries, and dual purpose batteries used in boats. A "trolling battery" specifically refers to a deep cycle battery built to supply steady current for electric trolling motors over long durations. Key differences include design for cranking versus deep-cycle discharge, plate construction and thermal management, and typical use cases such as starting a gasoline outboard or powering electronics and electric propulsion.
Customers praised this 12V 100Ah deep cycle battery for trolling motors, highlighting "a lot of power" and exceptional lightweight design at 11.1kg. The IP67 waterproof rating and Bluetooth monitoring received strong acclaim. Shoppers reported all-day runtime, with batteries lasting 8+ hours. One customer experienced a DOA unit but praised responsive support.
Got this WattLINK cable to connect my Ecoflow Delta 2 Max to an External 2.5 kw server rack battery and after a firmware update on the Delta 2 Max it works very well. There is a slight discrepency of charge rates (3-5% SOC difference), where the Ecoflow will charge before the external battery and the solar input reads 0 as if charging has stopped, but the server rack battery continues to charge (likely equalizing from the Ecoflow) and when it draws enough power from the D2M, the solar charging kicks back on again, maintaining the state of charge. I'll be posting a video on this awesome upgrade on my Youtube channel (http://www.youtube.com/@backtotheadk883) soon.
I bought this to upgrade from a 100ah lithium battery in my travel trailer. It more than tripled my capacity and easily fits in the factory camco double battery box with no modifications required. The price was great and I highly recommend this.
This is my second “dumb” 314Ah Mini. I was able to squeeze two of them into my 2016 Winnebago View 24G coach battery compartment with just a slight modification (removed 4 small sections of aluminum that make up the battery “box” and cut two small slits in the top in order to bend up the lip a bit). I use them to both feed the coach 12V system as well as to provide backup power to an EcoFlow Delta Pro that I use as storage/inverter/solar controller. These 3 units provide 11.6kW of storage in a compact and flexible arrangement. When boondocking I power my whole rig (30A) by connecting the shore power cable the Delta Pro and use its battery for the 110V system and the WattCycles for the 12V system. If my Delta Pro starts to run low, I can move power from the WattCycle batteries to the DeltaPro by using the EcoFlow 800W alternator charger. All of this is kept charged from the alternator using a Victron Orion XS 1400 50A DC-DC charger. Solar panels are next!
We received two 314ah batteries that had the tops popped open. Partially charged and appeared as new. Took a gamble and charged them at 50 amps with no issue. They appear as new, and I just used a marine battery strap to tie down the lid in case we ever need to do maintenance. Wrote to company and they responded with all the answers I needed. A great way to get twice the AH batteries for the same cost as 1 retail unit. Very happy with purchase and the company.
I wanted a deep cycle battery as a back up that could be attached to either my Dakota Lithium multi box or my Ancor power station. This battery not only vastly improves both but outshines them with its built in Bluetooth and great charge retention. It’s also built so per strong so I don’t need a separate case to carry it in.
I’m very happy with this purchase.
Will Prowes led me to this manufacturer and I am glad he did. After years of frustration with another manufacturer, I have a battery with plenty of capacity and the ability to see that the charging equipment I have is doing its job and how the loads in my camper draw down the stored charge.
I wanted the 314AH battery WattCycle offered and that was out of stock for a while. I entered my email and they notified me when it was available, then delivered it promptly following my order, with a promotional discount. It just fit in my camper's battery box and I followed instructions on WattCycle's web site to set up my Victron charging equipment. I am just two weeks out camping and everything is working as it should. Thanks WattCycle!
I have purchased four of these batteries and well, please with them. I have a lot of people look at my project and they love the way this Battery look and ask me How did I find this batteries and I told them I will be ordering six more of this batteries for another project that I’m working on, and I would like to take out time to thank watt cycle for their support and helping me with my project.
Works as described. Very good customer service... I ordered the eco flow adapter cable at the same time.
The battery speed a day later and arrived in very secure packaging. The adapter shipped a little later, but the responsive customer service team was able to get it shipped out quickly so I could get my battery connected to my Delta 2 and test it out. I highly recommend this to anyone with an Eco Flow Delta looking to excitable their power storage.
I replaced two FLA batteries on my sailboat with this. 1/3 the weight, 50% more usable energy, 10x the life and zero maintenance. The Bluetooth works great, but I thought the app needs a little work; it’s not intuitive what the buttons do…. Needs some online instructions. The on/off button on the battery is a great feature.
My Custom Offgrid Solar Designs Victron system is working great with my 4 WattCycle 314ah batteries. I had SOK 314ah batteries and could never get the cells to balance properly so I decided to try these and so far I have been impressed. The cell balancing is excellent! Customer support was good as well. Thanks [****]
Everything is working perfectly under high load and the tested capasity was as promised.
I just received my first Wattcycle 48 volt 100 AH battery. I am using it to power my Starlink set up and charging it with two 400 wat solar panels supplemented with AC power when the Ecoflow Delta 2 internal battery runs low. The system usually lasts about half way through the night on the internal battery. Now the system runs through the night with power to spare. Just ordered the 2nd battery. Looking forward to an adapter for the Delta pro 3 next
Long lasting power to play on the water all day.
I bought two of these to put in my RV. Just started testing them prior to installing them. I charged them both to 100%. I used a 2000W Xantrex inverter running a small electric heater for the load and a Victron shunt to measure the battery. The average current is about 120A dc when running the test. I set the inverter to shutdown at 11V so this is higher than the 10V normally used for capacity testing. Battery 1 showed 654Ah, battery 2 delivered 651Ah. I repeated the test a second time and got similar results. The battery case is steel so it seems rugged. I could barely lift the battery and I wish the handles were wider. I like that the terminals are on the end of the battery which works well for my installation.
It arrived quickly, although I haven't used it yet, the voltage is fine, I was able to charge it. I don't know exactly what secondhand means, but it looks new from the outside. I have previously bought 2pcs 24v/100Ah batteries from them and have been using them with satisfaction for my solar system for about a year. That's why I dared to buy a battery for my small boat here.
Wattcycle is the first company to hear a need and fulfill it. I've seen him change their shipping of seeing them change their way their terminals are set up their power switch and such a short period of time so this doesn't surprise me I got one of these cables and it works perfect. Keep up the good work guys.
I needed to replace my house battery with a lithium and this 100 AH Small footprint WattCycle was the perfect find. I can operate the boat for several days without a need for a recharge. It delivers consistent and ample voltage for my needs.
I just installed 2 of these 314 Ah batteries in my RV. So far they are working fine. Once they get a real test this spring I’ll know if they are good.
