Straightforward LiFePO4 storage without app-only extras
Store 3.84kWh in one 12V battery with up to 300A continuous output.
The RICH SOLAR ALPHA 3 LITE is a 12.8V, 300Ah LiFePO4 battery for RV, van, marine, cabin and off-grid 12V systems. The LITE design focuses on capacity, current capability and BMS protection without Bluetooth monitoring or an internal heater.
At a glance
The ratings that define the battery bank
Choose this version when you want the core battery capability and will monitor the system externally. Charging must stay within the published temperature range; the battery does not warm itself for below-freezing charging.
System fit
Keep the entire bank at its native 12V voltage.
Use a LiFePO4-compatible charger at 14.4V, match the inverter and DC loads to the 300A limit, and size conductors and overcurrent protection for the actual installation. Series connection is not supported for this product family.

Common questions
ALPHA 3 LITE setup questions
Does this LITE battery have Bluetooth or a heater?
No. Bluetooth monitoring and internal heating are not included. Use an external battery monitor if needed and keep charging within the published temperature limits.
How much inverter power can 300A support?
At 12.8V, 300A is roughly 3.84kW of DC power before voltage drop and conversion losses. Continuous AC output will be lower, and surge must remain inside both battery and inverter limits.
Can I connect batteries in series?
No. Series connection is not supported. Choose a native higher-voltage battery when the system voltage is above 12V.
How many cycles should I expect?
RICH SOLAR lists at least 4,000 cycles under the stated 77°F ±3.6°F test conditions. Depth of discharge and end-of-life threshold should be compared in the current specification sheet. Cycle life changes with depth of discharge, temperature, charge rate, storage and operating conditions.
