Rich Solar Alpha 2 Lite 800Ah LiFePO4 Battery Kit 10 2kWh Deep Cycle Power

ALPHA 2 LITE — 12V 200Ah LiFePO4 Battery (4-Pack 10.2 kWh Bank)

Overview

The ALPHA 2 LITE is a rugged, low-maintenance 12V 200Ah LiFePO4 battery designed for reliable energy storage. Built with premium lithium-iron-phosphate cells and an integrated BMS with individual cell fusing, it delivers steady power, strong thermal tolerance, and long service life. This listing is for a complete 800Ah (12V) battery bank (10.2 kWh) that includes four batteries and six 1 ft 2 AWG cables.

Benefits

• Dependable power when you need it — keeps appliances and systems running consistently without surprise drops in voltage.
• Fewer replacements and lower long-term costs thanks to long cycle life and a >10-year lifespan with proper care.
• Less time spent on maintenance — low self-discharge and built-in protections reduce routine checks and upkeep.
• Safer operation for home, vehicle, or off-grid systems due to individual cell fuses and comprehensive BMS protections.
• Easier integration into systems — stable output voltage and high amp capacity support sensitive electronics and heavy loads.
• Simplified installation and handling — each battery is lightweight for its capacity and features a removable carry handle.

Features

• Premium LiFePO4 (lithium-iron-phosphate) cell chemistry for stability and long life.
• Integrated Battery Management System (BMS) with individual cell fuses to isolate failed cells and maintain operation.
• Protections for overcharge, over-discharge, overcurrent, short circuit, and excessive temperature.
• High continuous charge and discharge capability (200A).
• Low self-discharge (<5% per month) for reliable stored energy over time.
• Stable nominal voltage for consistent device performance.
• Designed for high-temperature performance and extended cycle life (>4000 cycles).
• Removable carry handle for easier transport.
• Includes accessories for a complete 4-battery bank: four 12V 200Ah batteries plus six 1 ft 2 AWG battery cables.
