12.8V 314Ah LiFePO₄ Battery / 12.8V 314Ah

12.8V 314Ah LiFePO₄ Deep Cycle Battery
Model: VL-LFP-12314

1. Basic Introduction
Vanlith 12.8V 314Ah LiFePO₄ battery is a high-capacity deep cycle lithium battery
delivering 4,019Wh (4.0kWh) of usable energy. Designed for large-scale energy
storage, it is ideal for off-grid solar systems, RVs, marine applications, home
backup, and industrial UPS. Direct drop-in replacement for lead-acid batteries with
no system changes.

2. Key Features
314Ah capacity / 4.0kWh energy – one battery powers major appliances for hours

6,000+ cycles at 80% DoD – 10x longer life than lead-acid

Built-in BMS – full protection (over-charge, over-discharge, over-current, short
circuit, temperature)

High discharge current – 150A-200A continuous, 300A-400A peak (≤5s)

Expandable – up to 16 in parallel (5,024Ah / 64kWh) or 4 in series (51.2V)

Optional Bluetooth – monitor voltage, current, SOC, temperature via App

Optional self-heating – safe charging down to -20°C

Lightweight – approx. 28-32 kg (1/4 weight of lead-acid equivalent)

Wide temp range – discharge -20°C to +70°C; charge 0°C to +50°C

IP65/IP67 optional – waterproof for marine/outdoor use

Certified – CE, RoHS, MSDS, UN38.3

Warranty – 5 years
