12.8V 100Ah Lithium Iron Phosphate (LiFePO₄) Battery Specifications (Patent Pending)
Deep-cycle, high-performance LiFePO₄ battery designed for safe, reliable energy storage and continuous power delivery in demanding environments.
Not for Starting Engines
The NurturEnergy Lithium battery is a deep-cycle 12 V battery, specifically designed for energy storage and continuous power delivery. It is not intended for starting gasoline or diesel engines.
Using this battery for engine starting may damage the cells or void the warranty, as it is optimized for steady, long-duration discharge rather than the high-current bursts required for engine cranking.
Storage Capacity
Nominal Voltage: 12.8 V
Capacity: 100 Ah
Utilizes advanced LiFePO₄ technology with a flat voltage curve, ensuring steady power output throughout the discharge cycle.
Safe to discharge to 0 % state-of-charge, maximizing usable energy and efficiency.
Voltage
Nominal Voltage: 12.8 V
Can be connected in parallel with compatible BMS controllers to increase capacity.
Recommended Charging Voltage: 14.1 – 14.6 V DC.
Energy
Total Energy Capacity: 1.3 kWh
High energy density provides longer runtime and consistent performance compared to traditional lead-acid batteries of similar size and weight.
Operating Temperature
Range: –4 °F to 149 °F (–20 °C to 65 °C)
Ideal for rugged and harsh environments, including outdoor, industrial, marine, and off-grid applications.
Charge
Maximum Charging Current: 100 A
Recommended Charging Voltage: 14.4 V
Integrated BMS provides protection against overcharge, overcurrent, and temperature extremes.
Discharge
Maximum Continuous Discharge: 350 A for up to 300 seconds.
Suitable for high-power applications such as hydraulic lifts, electric vehicles, and industrial equipment.
Uniformly Distributed Internal Heating System
Activates at 0 °C (32 °F) to maintain cell temperature at 5 °C (41 °F).
Protects the battery during charging in cold conditions, preventing potential cell damage and ensuring safe, efficient operation.
Lifecycles (Battery Lifespan)
Up to 80 % capacity for 5 000 cycles under recommended conditions.
Typical SLA battery delivers only ~500 cycles, highlighting superior longevity and reliability of LiFePO₄ technology.
Reduces replacement frequency, maintenance costs, and environmental impact.
Size
Dimensions: 333 mm × 176 mm × 221 mm
Equivalent to a Group 31 battery for easy installation and replacement in tight spaces.
Terminals
M8 bolt terminals
Max Torque: 15 ft-lbs (20.3 Nm)
Designed for secure, high-current connections and easy maintenance.
Weight
27.55 lbs (12.5 kg) — about 60 % lighter than a comparable SLA battery, simplifying handling, installation, and improving efficiency.
Active BMS Protection
The integrated Battery Management System (BMS) provides:
• Cell balancing • Low voltage cutoff • High voltage cutoff
• Short-circuit protection • High temperature protection
Ensures reliable operation, extended battery life, and consistent performance.
Certifications
UL 1642 – Lithium battery safety standard
IEC 62133 – Safety requirements for portable sealed batteries
UN 38.3 – Safe transport certification
Ensures compliance and reliability for industrial, commercial, and transport applications.
Recommended Charger
12 V, 10 A LiFePO₄-compatible charger (sold separately).
Recommended Charging Voltage: 14.4 V
Using a standard lead-acid charger may only charge the battery to ~80 % of full capacity.
Warranty
5-year warranty covering manufacturing defects.
Rated for up to 10 years of operational life under recommended conditions.
Ensures long-term reliability and peace of mind.
