V-Link E 12.8V 314Ah LiFePO4 Battery

This high-capacity 4.02kWh energy storage module redefines the performance standards for a single 12V battery. Utilizing a proven 4S configuration and Grade-A LiFePO4 cells, it delivers double the capacity of traditional 150Ah models within a similar footprint—making it the ideal choice for space-constrained applications requiring maximum energy.


Weighing just ~32kg, this 314Ah module is 40% lighter than an equivalent lead-acid battery bank (which exceeds 80kg) yet offers a lifespan of over 6,000 cycles—10 to 15 times that of lead-acid batteries. An integrated smart Battery Management System (BMS) automatically handles all safety protections, while optional RS485/CAN interfaces and mobile app monitoring provide real-time visibility into battery status. Whether powering luxury yachts, fully off-grid cabins, or critical telecommunications sites, this 12.8V 314Ah battery delivers reliable energy with uncompromising performance.
