The Rich Solar ALPHA 2 12V 200Ah LiFePO4 Battery is a lithium iron phosphate battery for compatible RV, trailer, van, marine, cabin, camping, and off-grid electrical systems. Identified by SKU RS-B122S, it provides 2,560Wh nominal energy at 12.8V, with a 200Ah nominal capacity and 100A maximum charging and discharge ratings. This ALPHA configuration includes internal heat technology for supported low-temperature charging conditions and built-in Bluetooth for real-time monitoring through compatible mobile devices. Its integrated battery management system provides documented overcharge, over-discharge, over-current, short-circuit, temperature, and cell-balancing protection functions. The official specification sheet lists an IP65 waterproof and dustproof rating and a UL94 V-0 flame-retardant plastic shell.
The ALPHA 2 provides 200Ah of nominal lithium battery capacity with 2,560Wh of nominal energy for properly designed 12V systems. It is intended for compatible applications where a 200Ah battery configuration is appropriate, including RV, marine, camping, cabin, and off-grid electrical systems.
The battery includes a 100W internal heater controlled by the battery management system. According to the official manual, heating operates only when charging current is present, starts when the internal battery probe detects 41°F or below, and stops when the charger is disconnected or the detected temperature reaches 50°F or above.
Built-in Bluetooth communication allows supported battery operating information to be viewed on a compatible mobile device. This adds practical visibility for checking battery status in mobile and remote-use power systems where direct battery access may be less convenient.
The ALPHA 2 specification sheet identifies an integrated battery management system, IP65 waterproof and dustproof protection, and a UL94 V-0 rated plastic shell. The manual directs users to install the battery with its terminals facing upward, follow proper electrical connection requirements, and connect no more than four matching batteries in parallel.
With 2,560Wh of nominal energy storage, the ALPHA 2 is designed for compatible battery systems where added capacity matters for travel, remote stays, and off-grid power planning.
Internal heating and Bluetooth monitoring provide useful ownership features, while final system fit should be confirmed around charging equipment, inverter loads, cable sizing, mounting, and temperature conditions.
