Rich Solar Big Battery 24V 20kWh LiFePO4 Power Bank

ALPHA 4 LITE — 24V 100Ah LiFePO4 Battery (8-Unit 10.2 kWh Bank)

Overview

The ALPHA 4 LITE is a 24V, 100Ah LiFePO4 battery built with premium cells and an integrated battery management system (BMS). It is designed for long cycle life, reliable performance in wide temperature ranges, and low maintenance, making it suitable for off-grid power, home backup, and extended boondocking. Not intended to replace starting batteries.

Benefits

• Dependable backup power so you can keep lights, appliances, and essentials running during outages.
• Long lifespan and high cycle counts mean fewer replacements and lower long?term cost of ownership.
• Lightweight and compact compared with lead batteries, making installation and handling easier.
• Low self-discharge and stable voltage help preserve charge during storage and infrequent use.
• Built-in safety features reduce the worry of cell failure or unsafe operating conditions.
• Modular bank configuration scales to provide larger energy capacity for multi-day off-grid use.

Features

• LiFePO4 chemistry with high cycle life and stable chemistry under stress.
• Integrated smart BMS with per-cell fusing for safety and continued operation if an individual cell fails.
• High and low temperature disconnects and excessive heat protection to protect the battery and connected equipment.
• Overcharge, over-discharge, overcurrent, and short-circuit protections built into the BMS.
• Low self-discharge (<5% per month) for reliable storage and seasonal use.
• Consistent output voltage for predictable inverter and system performance.
• Lightweight design with a removable carry handle for easier transport and installation.
• Lifetime customer support and a 5-year warranty for system confidence.
• Packaged option: 8 batteries wired as a 24V 800Ah (10.2 kWh) bank including 14 one-foot 2 AWG battery cables.
