The Rich Solar ALPHA 1 is a 12V 100Ah lithium iron phosphate (LiFePO4) battery designed for compatible RV, marine, cabin, van, trailer, and off-grid power systems. Identified by SKU RS-B121S, it provides 1,280Wh nominal energy, a 12.8V nominal voltage, and up to 100A continuous discharge current. Built-in Bluetooth monitoring allows users to view state of charge, voltage, current, temperature, and remaining capacity through the compatible app. Internal heat technology supports low-temperature charging management, with charging disabled below 32°F, heating starting below 41°F, and heating stopping above 50°F according to Rich Solar. For mobile and off-grid battery storage applications, the ALPHA 1 combines compact lithium capacity, integrated monitoring, and built-in battery management protections in a 24 lb battery format.
The ALPHA 1 provides 100Ah nominal capacity and 1,280Wh nominal energy in a compact 12.8V battery. Rich Solar lists RV, marine, cabin, and off-grid applications, making this model suitable for properly designed systems where portable or space-conscious lithium storage is needed.
Cold-weather charging requires added protection in lithium battery systems. Rich Solar states that the ALPHA 1 disables charging below 32°F, activates internal heating below 41°F, and stops heating above 50°F, helping manage charging conditions during colder operation.
The built-in Bluetooth module supports app-based monitoring of state of charge, voltage, current, temperature, and remaining capacity. This allows owners to review battery status from a mobile device during travel, seasonal cabin use, or off-grid system operation.
The integrated Battery Management System (BMS) provides manufacturer-listed protection for overcharge, over-discharge, over-current, short circuit, cell balancing, and temperature conditions. The official specification sheet also identifies an IP65 water- and dust-protection rating and a UL94 V-0 flame-retardant rating for the plastic shell.
The compact 24 lb ALPHA 1 battery provides 1,280Wh of lithium iron phosphate storage for compatible mobile, marine, cabin, and off-grid energy systems.
Built-in Bluetooth monitoring lets owners review state of charge, voltage, current, temperature, and remaining capacity through the compatible app.
