The Rich Solar ALPHA 2 LITE 12V 200Ah LiFePO4 Battery is a lithium iron phosphate deep cycle battery for compatible RV, trailer, van, boat, camping, and off-grid electrical systems. Identified by SKU RS-B12200, it provides 2,560Wh nominal energy at 12.8V with a 200Ah nominal capacity. Rich Solar documentation for the RS-B12200 ALPHA 2 LITE does not list internal heating or Bluetooth communication; the separate RS-B122S ALPHA 2 product page lists Bluetooth and internal heat technology. This LITE model supports 200A maximum charging current and 200A continuous and maximum discharge current when used within documented operating limits. Rich Solar lists a UL94 V-0 rated plastic shell and an IP55 waterproof and dustproof rating for this exact model; installation must still follow the manual’s water-exposure and placement precautions.
The ALPHA 2 LITE provides 200Ah of nominal lithium battery capacity with 2,560Wh of nominal energy for properly designed 12V power systems. The official manual identifies use as electrical power storage for motorhomes, recreational vehicles, and camping applications, while Rich Solar’s product page also markets the battery for trailers, vans, boats, and off-grid systems.
This battery is listed with 100A standard charging and discharge current ratings, plus 200A maximum charging, continuous discharge, and maximum discharge ratings. Final system planning should confirm charger output, inverter demand, cable sizing, overcurrent protection, and connected load requirements before installation.
The built-in battery management system supports overcharge, over-discharge, over-current, short-circuit, charge-temperature, discharge-temperature, and balancing protection functions. The specification sheet also lists charging low-temperature protection, making operating-temperature limits important when planning seasonal or exposed installations.
The RS-B12200 is the ALPHA 2 LITE configuration and should not be confused with other ALPHA 2 variants. Rich Solar documentation for this exact LITE model does not list internal heating or Bluetooth communication. The official manual directs users to install the battery with terminals facing upward, requires electrical power supply connection by a qualified electrician, and permits no more than four matching batteries in parallel when installed according to its requirements.
With a 20.9" × 8.1" × 8.5" footprint and approximately 52.9 lb weight, this battery provides substantial lithium storage capacity in a compact rectangular enclosure.
For battery-bank installations, follow the manual’s terminals-up orientation and parallel-connection requirements, including matching batteries, suitable cabling, and proper system protection.
