High-capacity 12V lithium storage
2.56 kWh and 200A capability in one app-connected battery.
The RICH SOLAR ALPHA 2 PRO brings 12.8V, 200Ah LiFePO4 storage to higher-demand RV, cabin, tiny-home and backup systems. Bluetooth monitoring, internal heating and a 200A continuous-discharge rating make it a serious foundation for a properly designed 12V bank.
At a glance
More energy and current capacity for demanding 12V systems
This page is for RS-B122SP. The ALPHA 2 PRO includes Bluetooth, internal heating, 200A current ratings and ETL listing to UL 1973. ALPHA 2 and ALPHA 2 LITE use different feature, current and warranty specifications.
System fit
A 200A battery demands a complete high-current design.
Use a LiFePO4-compatible charger with a 14.4V charge target. Size the inverter, busbars, cable, lugs, disconnect and overcurrent protection around the battery’s documented 200A maximum charge and 200A continuous discharge ratings, with appropriate derating for the installation.

Common questions
ALPHA 2 PRO FAQ
How much energy does it store?
Nominal energy is 2,560Wh, calculated from the published 12.8V and 200Ah ratings. Usable energy depends on operating limits, temperature, load and system losses.
Does the heater let me charge at any temperature?
No. Follow the manual’s temperature and heater conditions. The heater requires charging input and is intended to warm the battery before normal charging continues.
Can any 3000W inverter use the full rating?
Not automatically. Confirm inverter input range, efficiency and surge demand, then ensure the required DC current remains within battery, BMS, cable, fuse and connection limits.
Can I put two batteries in series for 24V?
The current product-specific manual does not document series connection. Use a battery designed for the system’s native voltage instead.
