WattCycle 12V 314Ah MINI LiFePO4 Battery
WattCycle 12V 314Ah LiFePO4 Battery—your high-capacity solution delivering a true 314 Ah (4.01 kWh) energy reserve in a compact, portable package. Perfectly suited as an upgrade from any “12V 300Ah lithium battery,” it gives you the extra runtime you’ve been looking for without adding bulk.
Why 12V 314Ah Mini Lithium Battery
Built with high-performance EV-grade A+ cells and advanced 200A BMS, it gives 4.01kWh energy and 2560W max output, delivering up to 15000 cycles. The external IP65 waterproof rating makes the battery fearless of salt environments, and the internal metal frame ensures that the battery is safe even in bumpy environments.
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.
High-Capacity Performance
Compared with our 12V 280Ah MINI model, the new 314Ah battery packs 15% higher energy density and a 12% capacity bump—ending your energy anxiety once and for all. For those eyeing a “300Ah slim lithium battery 12V,” this is the same sleek form factor with extra juice. At just 27 kg (384 × 194 × 248 mm), it’s one-third the weight of lead-acid equivalents yet doubles the usable energy. Perfect when you need a “solar battery 12V 300Ah” solution without sacrificing cargo space.
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.
Power for Sustainable Adventures
For true energy independence, connect multiple WattCycle 12V 314Ah Mini lithium batteries to create a massive 64.31kWh power bank. This scalable system is ideal for extended motorhome trips, marine excursions, and off-grid living situations - providing reliable electricity for appliances, navigation systems, and essential devices wherever your journey takes you.
