Drop-in Lead-Acid Replacement
60% Lighter Weight & 20x Longer Cycle Life
Weighing only 6.5 kg (about 40% of an equivalent lead-acid battery), the Gobel LFP12.8-50 serves as a seamless plug-and-play upgrade that significantly reduces weight and drastically minimizes total cost of ownership over its service life.
Longer Cycle Life: Offers over 2,000 cycles at 100% DOD (1C discharge) and up to 5 times longer float/calendar life than lead-acid options.
Higher Usable Power: Delivers up to twice the effective power during high discharge rates while maintaining stable voltage capacity.
Ultra-Low Self Discharge: Less than 3% self-discharge per month for reliable standby performance.
Integrated 4S 50A BMS & Superior Chemistry Safety
Utilizing high-safety Lithium Iron Phosphate (LiFePO4) chemistry and a dedicated 4S 50A internal BMS, the battery protects against electrical and thermal risks during heavy operation.
Intelligent BMS Protection: Built-in 4S 50A BMS continuously protects against overcharge, over-discharge, over-current, and short circuits.
High Pulse Output: Supports 50A continuous discharge current and up to 150A peak pulse current (<3 seconds).
Intrinsic Safety: Zero risk of combustion or thermal explosion under severe impacts, short circuits, or overcharging conditions.
Modular Scalability: Up to 4S Series & 10P Parallel Configuration
Engineered with maximum installation flexibility in mind, enabling easy building of higher voltage or higher capacity banks.
Up to 4S Connection: Combine up to 4 units in series to create a 51.2V nominal energy storage bank.
Up to 10P Connection: Connect up to 10 units in parallel to expand capacity up to 500Ah (6.4kWh).
Rugged ABS Casing: Housed in a durable ABS plastic case with standard M6 screw terminals for clean and reliable wiring.
Wide Temperature Adaptability & Versatile Applications
Operates reliably in harsh conditions across a wide discharge temperature range from -20°C to 60°C.
Off-Grid Solar & Wind Storage: Store renewable solar or wind energy with 96%–99% discharge efficiency.
UPS & Telecom Backup: Instant discharge response for critical telecom equipment and medical backup devices.
Electric Mobility & Lighting: Ideal for electric mobility, trolling motors, and emergency illumination setups.
