The Rich Solar ALPHA 1 LITE 12V 100Ah LiFePO4 Battery is a compact lithium iron phosphate battery for compatible RV, marine, cabin, trailer, van, boat, and off-grid electrical systems. Model RS-B12100 provides 1,280Wh nominal energy at 12.8V, with a 100Ah nominal capacity and 100A maximum charging and discharge ratings. Its built-in battery management system supports overcharge, over-discharge, over-current, short-circuit, cell-balancing, and low-temperature charging protection. The ALPHA 1 LITE weighs approximately 24.3 lb and uses a plastic shell listed by Rich Solar with a UL94 V-0 flame-retardant rating and IP65 waterproof and dustproof rating. Rich Solar lists this LITE model without internal heating or Bluetooth monitoring, unlike ALPHA configurations that include those features.
The ALPHA 1 LITE stores 1,280Wh of nominal energy in a compact 12V-class battery format. It is intended for properly designed electrical systems where a lightweight lithium battery is needed for RV travel, camping, marine, cabin, or off-grid applications.
The integrated battery management system monitors key charging and discharging conditions while providing overcharge, over-discharge, over-current, short-circuit, cell-balance, and low-temperature charging protection. This supports more controlled battery operation when the unit is installed and charged according to the manufacturer documentation.
The battery is listed with a charging temperature range of 32°F to 131°F and a discharge temperature range of -4°F to 140°F. Its low-temperature charging protection is designed to prevent charging outside supported cold-weather conditions; this model does not include an internal heating function.
The RS-B12100 is the ALPHA 1 LITE configuration, not the heated or connected-monitoring version in the broader ALPHA battery lineup. Buyers needing internal heating or Bluetooth monitoring should compare configurations before selecting a battery for their system.

At approximately 24.3 lb with a 10.2" × 6.6" × 8.3" footprint, this battery offers compact lithium energy storage for space-conscious mobile and off-grid system layouts.
System planning should confirm charger compatibility, cable sizing, mounting position, parallel-battery requirements, and supported operating temperatures before installation or replacement.
