What Are the Key Specifications of the LiTime 12V 300Ah Battery?
This lithium iron phosphate battery delivers 3,072Wh energy capacity with 100A continuous discharge current. Its dimensions measure 12.9×7.1×8.5 inches, weighing 62.8 lbs—40% lighter than comparable lead-acid models. The built-in Battery Management System (BMS) prevents overcharge, over-discharge, and short circuits while enabling parallel connections for up to 4 units (1,200Ah total capacity).
Advanced cell balancing technology ensures ±20mV voltage difference between cells during operation, maintaining optimal performance throughout the battery’s lifespan. The modular design allows easy capacity expansion without specialized equipment – users can add units in 20 minutes using standard M8 bolt connectors. Field tests show 98.6% energy retention after 1,000 cycles when operated within recommended parameters.
| Parameter | LiTime 300Ah | AGM Equivalent |
|---|---|---|
| Cycle Life (80% DoD) | 4,000+ | 500-800 |
| Weight | 62.8 lbs | 108 lbs |
| Charge Temperature | -4°F to 140°F | 32°F to 113°F |
How Does Performance Compare in Solar Power Applications?
In solar installations, the LiTime 300Ah achieves 99% charge efficiency versus 85% for AGM batteries. Testing shows full recharge in 4.5 hours using 600W solar panels, compared to 8+ hours for lead-acid equivalents. Users report consistent 12.8V output during 3-day cloudy periods, maintaining 80% capacity where AGM batteries typically drop below 50%.
When paired with MPPT controllers, the battery’s wide voltage operating window (10V-14.6V) captures 22% more morning/evening solar energy than lead-acid systems. Real-world data from off-grid cabins shows 300Ah lithium banks supporting 2.4kWh daily loads for 5 consecutive days without sun, versus 2 days maximum with AGM configurations. The table below compares charging performance with different solar array sizes:
| Solar Array | 0-100% Charge Time | Energy Harvested |
|---|---|---|
| 400W | 6.8 hours | 2.7kWh |
| 600W | 4.5 hours | 2.9kWh |
| 800W | 3.2 hours | 3.1kWh |
What Maintenance Is Required for Optimal Lifespan?
Requires no water refilling or equalization charging. For best performance, store at 50% charge in environments below 113°F. Capacity calibration every 6 months (full discharge/charge cycle) maintains accuracy of battery meter. Terminal cleaning with dielectric grease every 500 cycles prevents corrosion. Self-discharge rate is 3% monthly versus 5-15% in lead-acid alternatives.
Periodic firmware updates through LiTime’s PC interface optimize BMS algorithms for specific applications. Marine users should conduct monthly visual inspections for salt accumulation, though the IP67 rating protects against direct water exposure. Storage recommendations vary by climate – batteries in desert environments show 0.8% capacity degradation annually when stored at 77°F, compared to 1.2% in tropical regions.
“Proper maintenance of LiFePO4 batteries focuses on three key aspects: state-of-charge management, temperature control, and connection integrity. The LiTime 300Ah simplifies these through smart self-monitoring features rarely seen in its price class.” – Energy Storage Solutions Magazine
