Deespaek 12V LiFePO4 Battery 100Ah

What Safety Mechanisms Does the Battery Include?

Built-in BMS protects against overcharge, over-discharge, short circuits, and thermal runaway. LiFePO4 chemistry is inherently non-combustible, unlike other lithium types. The battery’s flame-retardant casing and cell separation design further reduce fire risks during thermal stress.

The multi-layered protection system employs 13 safety protocols monitored in real-time. Unlike standard BMS units that only monitor voltage, Alitime’s system tracks individual cell temperatures through 4 sensors, automatically throttling charge rates if disparities exceed 2°C. This granular control prevents hot spots that degrade battery health. The casing undergoes UL94 V-0 flammability testing, sustaining direct flames for 30 seconds without ignition. For marine applications, IP65-rated seals block saltwater intrusion while allowing pressure equalization during altitude changes.

How Does Temperature Affect Performance?

Discharge works from -4°F to 140°F, but charging below 32°F requires reduced current. High temps above 122°F accelerate aging. The BMS automatically disconnects at -22°F/158°F extremes. Capacity drops 10% at -4°F compared to 77°F operation.

Electrolyte viscosity changes create measurable effects: at -4°F, internal resistance increases 40%, reducing peak discharge current capacity to 85A instead of the rated 100A. Users in arctic climates should insulate battery compartments and maintain 20% charge minimum to prevent lithium plating. Conversely, desert heat above 104°F triggers the BMS to limit charge acceptance to 0.5C, extending absorption time by 25%. Thermal modeling shows capacity retention improves 15% when operated between 50-86°F versus extreme ranges.

“The Alitime battery’s use of automotive-grade LiFePO4 cells sets it apart in reliability. Its 150A max discharge current supports high-demand applications like winches without voltage sag—a common issue in budget batteries. For users prioritizing cycle life over initial cost, it’s a game-changer.” – Renewable Energy Systems Consultant

FAQ

Can I use my existing lead-acid battery charger?

No—use only LiFePO4-specific chargers to avoid damaging cells.

Is parallel/series connection possible?

Up to 4 in parallel for 400Ah; series requires professional BMS reconfiguration.

Does cold weather permanently damage the battery?

No, but charging below freezing without temp compensation voids warranty.
