The Rich Solar ALPHA 3 LITE 12V 300Ah LiFePO4 Battery (RS-B123) is a 12.8V lithium iron phosphate battery that stores 3,840Wh in a 20.6 x 10.6 x 8.7 inch case weighing 71.3 pounds. It supports 300A of continuous charge and discharge current and connects up to four units in parallel for 1,200Ah at 12V.
The ALPHA 3 LITE is the value model of the ALPHA 3 line. It uses Grade A+ LiFePO4 cells rated for 4,000+ cycles, an IP65 UL94 V-0 flame-retardant housing and a full-protection BMS with low-temperature charging protection. It does not include the internal heater or Bluetooth of the standard ALPHA 3, which makes it a strong fit for warm climates and heated spaces.
One ALPHA 3 LITE does the job of three 100Ah batteries, with one set of terminals and one BMS. That means less wiring, fewer connections to check and a cleaner battery compartment.
The BMS allows 300A of continuous current in both directions, enough to support a large 12V inverter and fast charging from big chargers or solar arrays.
Grade A+ LiFePO4 cells are rated for 4,000+ cycles, far more than typical lead-acid batteries. Self-discharge is 5% or less per month, so a stored battery holds most of its charge between uses.
The BMS automatically stops charging when it is too cold to charge safely and resumes when conditions improve. Charging is rated from 32°F to 131°F and discharging from -4°F to 140°F.
The battery management system protects against overcharge, over-discharge, overcurrent, short circuits and temperature extremes.
The UL94 V-0 flame-retardant housing is rated IP65 against dust and water spray. The LiFePO4 chemistry needs no watering, equalizing or regular maintenance.
RVs and fifth wheels. Run a fridge, microwave and inverter loads from one 12V battery in mild climates.
Cabins and tiny homes. Store solar energy for evening lights, a fridge and electronics in a heated space.
Home backup. Power a 12V inverter charger for outages with a battery kept indoors.
Boats. Power house loads and electronics. Rich Solar lists marine use as a primary application.
Vans and campers. Get 300Ah of storage for trips in warm weather.
Versus the standard ALPHA 3. The ALPHA 3 adds internal heating, Bluetooth monitoring and a 5,000+ cycle rating. Choose the LITE when the battery stays above freezing for charging or when you already use a separate battery monitor.
Versus three 100Ah batteries. Three batteries need more space, more cables and careful matching. The LITE puts 300Ah in one case with one BMS.
Versus lead-acid batteries. A lead-acid bank of similar usable capacity is much heavier, needs maintenance and lasts far fewer cycles.
This may be a good fit if
No. The LITE has neither. It includes low-temperature charging protection, which pauses charging in the cold.
Up to four, for 1,200Ah and 15,360Wh at 12V.
For a parallel bank, use matching batteries. A LITE would stop charging in the cold while a heated ALPHA 3 keeps going, which unbalances the bank.
Rich Solar provides a 5-year warranty on the ALPHA 3 LITE.
The Rich Solar ALPHA 3 LITE 12V 300Ah LiFePO4 Battery gives RVs, cabins and backup systems 3,840Wh of storage and 300A of current in one maintenance-free battery. At Outbound Power, we help customers choose between battery models and match them to their inverters, chargers and solar. If you have questions, our team is happy to help.
