Twice the energy of a 100Ah battery in one 12V case
Store 2.56kWh with Bluetooth monitoring and cold-weather charging support.
The RICH SOLAR ALPHA 2 is a 12.8V, 200Ah LiFePO4 battery for higher-capacity RV, trailer, boat, cabin and backup banks. A 100A BMS supports measured 12V loads, while internal heat and app monitoring make the battery easier to manage across changing seasons.
At a glance
More 12V runtime without building a multi-battery bank
RICH SOLAR documents up to four identical ALPHA 2 batteries in parallel and does not support series connection. Choose a native 24V or 48V battery for higher-voltage systems.
System fit
Size the inverter from the 100A battery limit.
At 12.8V, a 100A continuous battery limit is roughly 1,280W of DC power before voltage drop and inverter losses. Large 12V inverters may require multiple properly paralleled batteries or a different battery architecture.

Common questions
ALPHA 2 setup questions
Can I connect two ALPHA 2 batteries in series for 24V?
No. Series connection is not supported. Use a native 24V battery for a 24V system.
How many ALPHA 2 batteries can be connected in parallel?
RICH SOLAR documents up to four identical batteries in parallel. Use matching models and ages, equal-length conductors, closely matched pack voltage and correctly sized protection.
How does the internal heater work?
The 100W heater activates with charging current when battery temperature is at or below 41°F and stops when charging is removed or battery temperature reaches at least 50°F. It does not replace the full temperature rules in the manual.
How much AC power can one battery support?
The battery is limited to 100A continuous discharge. Practical AC output depends on battery voltage, cable loss and inverter efficiency, so size the inverter and loads from the current limit—not the 2.56kWh energy rating alone.
