Exactly what I needed.

Retired Electrical Engineering Prof here: Just installed 2x 314Ah to replace 4 Battleborn 100Ah that were defective after 5 years in my motorhome. Watt cycle units are much smaller with 50% more capacity and 2x 314Ah cost less than 4x Battleborns.

So far working well

Bought 2 of these Mini 314 batteries and after one month seem to be working well. Two issues, price fluctuates depending which site, time of day, etc and the batteries arrived almost 1 week apart. We were lucking we had the time and flexibility to install them separate, but this is not ideal for anyone using the batteries in the same system.

Great battery and excellent service!

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!

Minute Man Solar (75.6K subscribers) put together a fast, budget-friendly DIY off-grid/backup solar build using WattCycle batteries + a 6000XP inverter—showing how you can get up to ~16kWh of storage and ~6kW output for around $4,000, with room to expand and straightforward monitoring. He also shares practical tips on wiring, safety fusing, battery balancing, and a “dark start” recovery setup for real off-grid reliability.

Unleash More Energy in a Smaller Size

Compared to a 12V 280Ah LiFePO4 battery, it offers 11% more capacity while taking up less space. It's ideal for extended outdoor camping trips, RV travel, and boat fishing.

Safety in Every Aspect

WattCycle lithium batteries offer absolutely safe battery performance. A 200A BMS with over 20 protections and a 250A(1s) peak discharge current allow you to use high-power appliances with peace of mind. It also features an innovative design with an internal metal frame and external tough casing, effectively reducing battery swelling, maintaining cell stability, and allowing for installation and use in any orientation.

Weather-Proof Performance

Whether you’re charging in 113 °F summer heat or discharging at –4 °F ice-fishing, this battery keeps pace. Charge range: 32 °F to 113 °F (0 °C–45 °C). Discharge range: –4 °F to 140 °F (–20 °C–60 °C). For anyone running a “solar battery 12V 300Ah” system in extreme climates, this pack won’t flinch.

Triple-Shield Safety

The WattCycle 12V 314Ah LiFePO4 Battery stands up to harsh conditions thanks to its unique full-aluminum internal frame,Which not only reinforces the cell structure but also integrates cooling fins that improve heat dissipation by 30 %. That means during heavy discharge or rapid charging, excess warmth is whisked away faster—protecting cell health and maintaining peak performance. Meanwhile, braided copper wires have been newly added inside the battery, enabling it to provide more than 50% of the power with the minimum voltage drop. This three-tier design makes it one of the safest 12V 300Ah deep cycle battery options on the market.

Simplified Comparison

For those running three 12V 100Ah batteries in parallel, you’d typically combine to 300 Ah. That setup adds weight, wiring complexity, and more points of failure. By choosing one WattCycle 314Ah MINI battery instead. you get additional benefits.

Scalable Energy Expansion

Scale up your array with extra WattCycle battery to build a 4S4P (64.3 kWh) mega-bank ideal for large solar arrays or whole-home backup. your go-to for WattCycle 12V 314Ah batteries that need to grow as your demand does.
