The Rich Solar ALPHA 2 PRO 12V 200Ah LiFePO4 Battery is a lithium iron phosphate battery for compatible RV, motorhome, camping, cabin, and tiny-home electrical storage systems. Identified by SKU RS-B122SP, it provides 2,560Wh nominal energy at 12.8V with a 200Ah nominal capacity and 200A maximum charging and discharge ratings. This PRO configuration includes a 100W internal heating function for supported low-temperature charging conditions and built-in Bluetooth for compatible mobile-device battery monitoring. Rich Solar documentation lists an IP55 waterproof and dustproof rating, a UL94 V-0 flame-retardant plastic shell, and Intertek ETL listing with conformity to ANSI/CAN/UL 1973. The ALPHA PRO Series is covered by Rich Solar's 10-year prorated limited warranty, subject to the manufacturer's warranty terms and installation requirements.
The ALPHA 2 PRO provides 200Ah nominal capacity and 2,560Wh nominal energy for properly designed 12V power systems. Its documented 200A maximum charging and discharge ratings require compatible charging equipment, inverter loads, wiring, overcurrent protection, and connected-load planning.
The battery includes a 100W internal heater controlled through the battery management system. According to the official manual, heating operates only when charging current is present, begins 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 provides compatible mobile-device visibility into supported battery operating information. This is a practical ownership feature for compatible RV, motorhome, cabin, tiny-home, and camping power systems where battery-status visibility supports system monitoring.
Rich Solar documentation identifies ETL certification and conformity to ANSI/CAN/UL 1973 for this battery model. The manual also directs users to keep terminals facing upward, follow qualified electrical connection practices, and connect no more than four matching batteries in parallel.
With 2,560Wh of nominal energy and a 20.9" × 8.1" × 8.5" footprint, the ALPHA 2 PRO offers substantial lithium storage capacity for compatible power-system layouts.
Internal heating, Bluetooth monitoring, and documented current ratings help buyers compare configurations, while final system fit should be confirmed before installation.
