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.
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.
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.
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.
