Couldn't load pickup availability
The Lithtech 12V 314Ah LiFePO4 Battery is a flagship-grade lithium iron phosphate battery built for high-demand energy storage applications — large solar systems, whole-home backup, off-grid cabins, and serious marine or overlanding builds. Delivering 3840Wh from a single unit, this battery is designed for installations where runtime and load capacity are non-negotiable.
Built with a rugged IP65-rated ABS housing, the TE12314B is fully dust-tight and water jet resistant, making it suitable for tougher environments where lesser batteries would fail. At 12.8V nominal with a 200A continuous discharge rating, it can handle the startup surges of heavy loads — compressors, large inverters, power tools — without flinching. What sets it apart from the rest of the range is built-in Bluetooth connectivity, allowing you to monitor state of charge, voltage, current, and cell health directly from your smartphone — no additional hardware required.
The integrated BMS with 760A short circuit cut-off and 157A maximum charge acceptance provides comprehensive protection and fast recharge capability from solar arrays or generators. The battery supports up to 4 units in series and 4 in parallel (4S4NP), offering a clear upgrade path as your energy needs expand.
