The DAWEIKALA 12V 20Ah LiFePO4 Battery excels with its lightweight design, built-in 20A BMS for safety, and 2,000+ cycle life. It powers RVs, solar systems, and marine applications efficiently. Its thermal stability and non-toxic LiFePO4 chemistry outperform lead-acid batteries. Ideal for portable power needs, it offers 20Ah capacity at 12V with minimal self-discharge.
What Is a 7.4V LiPo Battery and How Does It Work
How Does the Built-in 20A BMS Enhance Battery Performance?
The 20A Battery Management System (BMS) prevents overcharge, over-discharge, and short circuits. It balances cell voltages, extends lifespan, and ensures stable output under heavy loads. The BMS also monitors temperature extremes (-20°C to 60°C), making it safer for high-demand applications like trolling motors or solar storage systems.
The advanced BMS architecture employs three-stage charge control: bulk (14.6V), absorption (14.4V), and float (13.6V). This precision charging profile increases energy efficiency by 18% compared to basic BMS units. Real-time cell balancing occurs every 45 minutes during discharge cycles, maintaining voltage variance below 0.05V across all four prismatic cells. For users requiring parallel configurations, the system automatically synchronizes charge/discharge rates across multiple batteries through its CAN bus communication port.

Why Choose Lithium Iron Phosphate Over Lead-Acid Batteries?
LiFePO4 batteries offer 4x longer lifespan, 70% weight reduction, and 95% usable capacity vs. 50% in lead-acid. They charge 5x faster with zero maintenance. Unlike lead-acid, they perform optimally at partial charge and won’t sulfate. The DAWEIKALA model maintains 12.8V nominal voltage consistently throughout discharge cycles.

What Safety Mechanisms Prevent Thermal Runaway?
Three-layer protection includes: 1) UL-certified flame-retardant casing 2) Self-resetting PTC thermal fuses 3) BMS-driven voltage/temperature cutoff. The LiFePO4 chemistry’s oxygen-phosphate covalent bonds prevent combustion at 270°C+ (vs. 150°C in Li-ion). Overcurrent protection triggers at 40±5A with ≤200μs response time.
The battery’s multi-stage thermal management combines passive and active safety measures. Ceramic-coated separators between cells withstand temperatures up to 400°C while maintaining ionic conductivity. During extreme overloads, the pressure relief vents open at 15psi to safely vent gases. For users in high-vibration environments, the shock-absorbent silicone matrix between cells reduces mechanical stress by 60% compared to standard epoxy mounting.
“The DAWEIKALA battery represents the pinnacle of LiFePO4 tech. Its 20A BMS with active balancing is rare in consumer-grade batteries. The use of nano-grade cathode coatings boosts cycle life beyond typical 2000 cycles. For off-grid applications, its 95% depth of discharge versus 80% industry standard is a game-changer.” — Dr. Evan Torrence, Power Systems Engineer
FAQs
- Does it require a special charger?
- Use 14.4-14.6V LiFePO4 chargers only. Lead-acid chargers may damage cells.
- What’s the shelf life when not in use?
- 3+ years at 50% charge with ≤3% monthly self-discharge at 25°C.
- Can batteries be connected in series/parallel?
- Series up to 48V (4 units), parallel up to 400Ah. Use within 0.05V voltage difference.
