Rich Solar Alpha 400Ah LiFePO4 Battery Kit 5 12kWh Power For Off Grid RV

ALPHA 2 LITE — 400Ah (2 × 200Ah) 12V LiFePO4 Battery Bank

The ALPHA 2 LITE is a robust 12V LiFePO4 battery system built from high-quality lithium-iron-phosphate cells. This listing includes two 12V 200Ah batteries and cabling to form a 400Ah, 5.12 kWh battery bank that delivers steady power, built-in safety, and low maintenance for residential, mobile, or off-grid use.

Benefits

• Dependable power when you need it: supports high loads and keeps sensitive equipment running with a stable output voltage.
• Less upkeep and fewer replacements: long cycle life and low self-discharge reduce maintenance and replacement frequency.
• Peace of mind from built-in safety: individual cell fuses plus BMS protections minimise the risk of cell damage and system failures.
• Simpler installation and handling: lightweight design and removable carry handle make positioning and servicing easier.
• Usable in a wide range of environments: wide charge and discharge temperature ranges let you operate in varying climates.

Features

• Premium LiFePO4 cells for stable chemistry and long life.
• Integrated Battery Management System (BMS) with overcharge, over-discharge, overcurrent, short-circuit, and temperature protections.
• Individual cell fuses so a single cell fault won’t disable the whole battery.
• High continuous discharge and charge current capability for demanding loads (200A).
• Low self-discharge for reliable storage and seasonal use.
• Removable carry handle and lightweight construction for easier handling.
• Stable output voltage to protect electronics and inverters.
