What Are Features Of Weize 12V 100Ah Mini LiFePO4 Battery?
The Weize 12V 100Ah Mini LiFePO4 Battery is a compact lithium-iron-phosphate energy storage solution designed for versatility and durability. It features a 25% smaller footprint than traditional models while delivering 1280Wh energy output. With a built-in 100A Smart BMS and 15,000-cycle lifespan, it’s optimized for RV, marine, solar, and off-grid applications. Charging at 14.4V/10A achieves full capacity in ~10 hours. Its low-temperature protection and 10-year design life make it ideal for harsh environments.

What are the key technical advantages of Weize’s 100Ah LiFePO4 battery?
This battery leverages LiFePO4 chemistry for thermal stability and longevity, achieving 5x the lifespan of lead-acid equivalents. At 24 lbs, it’s 50% lighter than AGM batteries while maintaining deep-cycle performance even at 80% DoD. The 100A BMS enables 1280W continuous discharge, sufficing for power-hungry systems like trolling motors. Pro Tip: Use temperature-compensated charging above 0°C to prevent BMS-triggered charging lockouts during cold weather.
How does the Mini design impact installation flexibility?
The compact 25% size reduction compared to previous models allows installation in tight spaces like marine battery boxes or RV compartments. Dimensions typically measure 12.9″x6.8″x8.4″, enabling vertical/horizontal mounting. This form factor provides energy density of ~90Wh/kg, critical for mobile applications where weight distribution matters. For example, two units can replace four 100Ah AGMs in a solar bank while saving 120+ lbs. Table 1 compares footprint against competitors:
| Model | Volume (ft³) | Weight (lbs) |
|---|---|---|
| Weize Mini | 0.78 | 24 |
| Standard LiFePO4 | 1.02 | 28 |
| AGM Equivalent | 1.35 | 58 |
What BMS protections are integrated?
Weize’s 100A Smart BMS provides seven-layer protection: overcharge (≥15V), over-discharge (≤10V), short-circuit (0ms cutoff), overcurrent (≥150A), reverse polarity, cell imbalance, and temperature (-20°C–60°C operation). The system automatically rebalances cells during charging at 14.6V. Practically speaking, this means surge tolerance for motor startups up to 300A for 3 seconds. However, sustained loads above 100A may trigger protective shutdowns. Rhetorical question: Why risk $300 inverters when BMS safeguards exist?

FAQs
Yes, up to four units in parallel via 2/0 AWG cables. Ensure interconnects <3% voltage drop and use identical battery models/ages to prevent imbalance.
What’s the shelf life when inactive?
Store at 13.2–13.8V (50% SoC) in 15–25°C environments. Recharge every 3–5 months—LiFePO4 self-discharges at 2–3% monthly vs. 5% for lead-acid.
Does the battery support alternator charging?
Only with external regulators limiting voltage to 14.6V. Direct alternator connections risk BMS tripping from automotive systems’ 15V+ spikes.
