What Are the Key Features of a 12V 90Ah LiFePO4 Battery?
This battery type delivers 12V voltage and 90Ah capacity, providing stable power output with a 95% depth of discharge. Built-in Battery Management Systems (BMS) prevent overcharging, overheating, and short circuits. Its compact design weighs 10-12 kg (vs. 25-30 kg for lead-acid), lasts 8-10 years, and supports rapid charging (0-100% in 2 hours).
How Does It Compare to Traditional Lead-Acid Batteries?
LiFePO4 batteries outperform lead-acid in cycle life (10x longer), energy efficiency (98% vs. 80%), and temperature tolerance. They maintain consistent voltage during discharge, unlike lead-acid batteries that experience voltage drops. Though 2-3x costlier upfront, their total ownership cost is 60% lower due to longevity and reduced replacement needs.
| Parameter | LiFePO4 | Lead-Acid |
|---|---|---|
| Cycle Life | 3,000-5,000 | 300-500 |
| Weight (kg) | 10-12 | 25-30 |
| Charging Time | 2 hours | 6-8 hours |
Extended use cases reveal even greater advantages. For commercial fleets, LiFePO4 batteries reduce downtime through faster charging – trucks can complete 3 full charges daily versus 1 with lead-acid. The stable voltage curve ensures sensitive electronics like GPS trackers and refrigeration units operate without interruptions. Marine applications benefit from 70% weight reduction, improving fuel efficiency by 8-12% in sailboats.
Which Vehicles Are Compatible with This Battery?
Compatible with cars, RVs, boats, golf carts, and electric scooters. Fits diesel/petrol vehicles requiring 12V systems and supports start-stop technology. Ensure your alternator provides 14.4V±0.2V charging voltage. For electric vehicles, verify compatibility with the motor’s peak current draw (up to 300A for 90Ah models).
Can It Power Off-Grid Solar Systems?
Yes. With 2,880Wh energy storage (12V×90Ah×2.66 conversion factor), it efficiently stores solar energy. Pair 4 units in series for 48V systems. LiFePO4 handles partial charging better than lead-acid, achieving 90% efficiency in solar applications. Ensure charge controllers are LiFePO4-compatible (e.g., MPPT with 14.6V absorption voltage).
What Safety Mechanisms Prevent Overheating?
BMS monitors cell balance, temperature (-20°C–60°C), and current. Thermal fuses disconnect at 80°C±5°C. Flame-retardant casing (UL94 V-0 rated) and ceramic separators prevent thermal runaway. Pressure relief valves activate at 15-20 psi to vent gases during extreme conditions.
| Safety Feature | Activation Threshold | Protection Scope |
|---|---|---|
| BMS | Continuous Monitoring | Overcharge/Discharge |
| Thermal Fuse | 80°C±5°C | Circuit Interruption |
| Pressure Valve | 15-20 psi | Gas Venting |
Advanced models incorporate dual-layer protection with redundant temperature sensors spaced 2cm apart for accurate thermal mapping. Crash sensors automatically disconnect terminals upon detecting 15G+ impacts, preventing short circuits in accidents. Submersion protection up to IP67 rating allows temporary underwater operation – critical for amphibious vehicles and marine applications.
How Much Does a 12V 90Ah LiFePO4 Battery Cost?
Prices range from $400 to $800, depending on BMS quality and brand. Installation costs add $50-$100. Budget $1,200-$1,600 for a solar setup with 3 batteries. ROI is achieved in 3-4 years through fuel savings (5-10% MPG improvement) and reduced replacements.
What Environmental Benefits Does It Offer?
LiFePO4 contains no toxic lead or acid, reducing landfill contamination. Its 8-10 year lifespan decreases e-waste by 80% compared to lead-acid. Manufacturing emits 35% less CO2, and 99% of materials are recyclable. Solar pairing cuts annual carbon footprint by 1.2-1.5 metric tons per battery.
