Frequently Bought Together
Rich Solar ALPHA 2 PRO 12V 200Ah LiFePO4 Battery
The Rich Solar ALPHA 2 PRO is a premium 12V 200Ah lithium iron phosphate battery built for RVs, vans, cabins, tiny homes, marine systems, and off-grid solar storage. With 2560Wh of energy capacity, 7,000+ lifetime cycles, internal heat technology, a Safe BMS System, industrial-grade battery cells, UL1973 certification, and a 10-year warranty, it gives serious 12V power systems a long-life lithium storage foundation.
Product Overview
The ALPHA 2 PRO is designed for customers who want a higher-end 12V lithium battery with stronger cycle life, premium protection, and better long-term durability. It is a strong fit for RV solar systems, camper vans, travel trailers, cabins, tiny homes, boats, and off-grid solar storage builds where dependable battery capacity matters.
Compared with traditional lead-acid storage, LiFePO4 chemistry offers longer service life, more usable energy, lower maintenance, and more consistent performance over time. The ALPHA 2 PRO adds internal heating, high-quality battery cells, and a Safe BMS System to support more demanding mobile and off-grid use.
Built for Premium 12V Solar and Off-Grid Power
The ALPHA 2 PRO gives 12V systems a powerful lithium battery upgrade with the capacity, cycle life, and protection needed for real RV, marine, cabin, and off-grid use. It is ideal for customers who want more than a basic battery and are building a system they expect to rely on for years.
Key Features That Matter
The ALPHA 2 PRO focuses on the features customers actually care about when choosing a premium 12V lithium battery: cold-weather support, long cycle life, safer battery management, and higher-grade cell construction.
Internal heating helps improve cold-weather usability for RVs, trailers, cabins, marine compartments, and seasonal off-grid systems. It is especially useful when battery charging conditions can drop below normal lithium charging temperatures.
Designed for consistent and durable performance, the ALPHA 2 PRO gives solar, RV, marine, and off-grid users a longer-lasting battery option than traditional lead-acid storage and many basic lithium batteries.
The Safe BMS System helps the battery respond accurately and quickly to abnormal conditions, including overcharge, over-discharge, overcurrent, short-circuit, low temperature, and high temperature situations.
Premium cell construction helps support long-term durability, stable output, and dependable performance for customers who expect their battery bank to handle regular solar, RV, marine, or off-grid use.
