What Are The Specs Of 12V HUSKY 2 LiFePO4 Battery?

The 12V HUSKY 2 LiFePO4 battery is a deep-cycle lithium iron phosphate (LiFePO4) battery designed for high-performance applications like electric vehicles, solar storage, and marine systems. While specific “HUSKY 2” branding isn’t detailed in available specs, standard 12V LiFePO4 configurations typically feature a nominal voltage of 12.8V, capacities ranging from 20Ah to 200Ah, and cycle lifespans exceeding 2,000 cycles at 80% depth of discharge (DoD). These batteries integrate built-in BMS for overcharge/over-discharge protection and operate efficiently in temperatures from -20°C to 60°C.

What is the voltage range of a 12V HUSKY 2 LiFePO4 battery?

A 12V LiFePO4 battery operates at a nominal 12.8V, with a charging voltage between 14.4–14.6V and a cut-off voltage of 10V under load. The BMS prevents over-discharge below 10V to preserve cell integrity.

LiFePO4 chemistry maintains a stable voltage curve, delivering 12.8V nominal (3.2V per cell × 4 cells). During charging, the BMS balances cells to ensure uniform 3.6V per cell (totaling 14.4V). Unlike lead-acid batteries, voltage doesn’t sag significantly under load—a 12V HUSKY 2 battery sustains 12.5–13V even at 80% discharge. Pro Tip: Use a LiFePO4-specific charger with ±0.5% voltage accuracy; mismatched chargers risk premature BMS shutdowns. For example, a 12V 100Ah LiFePO4 pack can power a 1,200W RV inverter for 1 hour at full load.

What capacity options are available?

Standard capacities range from 20Ah to 200Ah, with energy outputs scaling from 256Wh (20Ah) to 2,560Wh (200Ah). Higher-capacity models use prismatic cells for compact designs.

Capacity determines runtime: A 12V 100Ah LiFePO4 battery provides 1,280Wh, sufficient to run a 100W solar setup for 12.8 hours. Larger capacities (e.g., 200Ah) suit energy-intensive applications like off-grid cabins or trolling motors. Pro Tip: Opt for 20–30% extra capacity beyond calculated needs to account for inefficiencies. For instance, a 12V 120Ah battery with 1,536Wh can power a 500W e-bike motor for ~3 hours. Lower-capacity 20Ah units are ideal for portable power stations or backup lighting.

How does temperature affect performance?

LiFePO4 batteries operate optimally between -20°C to 60°C, with reduced charging efficiency below 0°C. Built-in BMS protects against thermal extremes.

At -10°C, capacity drops by ~15%, but discharge remains stable. Charging below freezing requires heaters or reduced currents to prevent lithium plating. Above 45°C, the BMS throttles current to avoid thermal runaway. Pro Tip: Install batteries in ventilated areas—ambient temperatures above 35°C accelerate capacity fade by 0.5–1% per month. For Arctic applications, insulated enclosures with 50W heating pads maintain cells above -5°C.

What safety features are included?

Standard protections include overcharge, over-discharge, short-circuit, and temperature monitoring via a 4-layer PCB BMS. Some models add moisture-resistant ABS+PC casings.

The BMS disconnects loads at 10V and halts charging at 14.6V. Multi-stage fault detection resolves issues like cell imbalance within 500ms. For example, if one cell hits 3.65V during charging, the BMS redistributes energy to weaker cells. Pro Tip: Test BMS functionality monthly by simulating a 15V input—proper systems will disconnect within 2 seconds.

What’s the lifespan of a 12V LiFePO4 battery?

LiFePO4 batteries achieve 2,000–5,000 cycles at 80% DoD, outperforming lead-acid’s 300–500 cycles. Capacity retention stays above 80% for 8–10 years with proper maintenance.

Cycle life depends on depth of discharge: At 50% DoD, lifespan extends to 4,000+ cycles. High-current discharges (>1C) reduce longevity by 10–15%. Pro Tip: Store batteries at 50% charge if unused for >1 month—full charge storage accelerates cathode degradation. For example, a 12V 100Ah battery cycled daily at 30% DoD lasts ~15 years in solar applications.
