What Are the Key Specifications of the LiTime 12V 300Ah Battery?
The LiTime 12V 300Ah LiFePO4 battery operates at a nominal voltage of 12.8V with a 300Ah capacity, delivering 3,840Wh of energy. It weighs 62 lbs, 60% lighter than lead-acid equivalents. The battery supports a continuous discharge current of 200A (400A surge) and charges efficiently at 0.2C–1C rates. Operating temperatures range from -4°F to 140°F (-20°C to 60°C).
| Specification | LiTime LiFePO4 | Lead-Acid |
|---|---|---|
| Weight | 62 lbs | 150 lbs |
| Cycle Life | 3,000–5,000 | 300–500 |
| Depth of Discharge | 95% | 50% |
What Safety Features Are Integrated Into the LiTime 12V 300Ah Battery?
The LiTime battery includes a BMS with overcharge, over-discharge, short-circuit, and over-temperature protection. Its flame-retardant casing and stable LiFePO4 chemistry prevent thermal runaway. Unlike traditional lithium-ion batteries, LiFePO4 cells resist combustion even under puncture or impact, ensuring compliance with UL and UN38.3 safety standards.

The integrated Battery Management System continuously monitors each cell’s voltage, temperature, and current flow. This prevents overcharging during peak solar production and over-discharging during high energy demand. The IP65-rated casing protects against water ingress in marine environments, while field tests show it withstands direct short circuits for 30 seconds without damage. These features make it ideal for remote installations where maintenance access is limited.
Can the LiTime 12V 300Ah Battery Be Used in Solar Power Systems?
Yes, the LiTime 12V 300Ah is optimized for solar storage. Its high cycle life and 95% usable capacity make it ideal for daily cycling. Compatible with most solar charge controllers, it accepts irregular solar input and maintains efficiency at partial states of charge. It pairs well with inverters up to 2,400W (12V systems).
When integrated with solar arrays, the battery’s 3% monthly self-discharge rate preserves energy during cloudy periods. It operates efficiently from desert heat to mountain cold, unlike lead-acid batteries that struggle below freezing. Users achieve 98% round-trip efficiency with MPPT controllers compared to 85% with AGM systems. The modular design supports gradual expansion – add units as energy needs grow without system overhauls.
How Should You Maintain the LiTime LiFePO4 Battery for Maximum Lifespan?
Store the battery at 50% charge in dry, cool environments (59°F/15°C optimal). Avoid deep discharges below 10% SOC. Use a LiFePO4-compatible charger (14.2–14.6V absorption voltage). Balance cells every 6 months if used in series/parallel. No regular maintenance is required beyond cleaning terminals and ensuring firmware updates for integrated BMS (if applicable).
What Applications Are Best Suited for the LiTime 12V 300Ah Battery?
- RV and marine house batteries
- Off-grid solar storage
- Electric trolling motors
- Backup power for telecom equipment
- Medical mobility devices
