Rich Solar ALPHA 2 LITE 12V 200Ah LiFePO4 Battery
The Rich Solar ALPHA 2 LITE is a value-focused 12V 200Ah lithium iron phosphate battery built for RVs, trailers, vans, boats, cabins, camping setups, and off-grid solar systems. With 2560Wh of usable energy, 4,000 lifetime cycles, durable LiFePO4 cell construction, BMS protection, and a compact 52.9 lb design, it gives 12V power systems a dependable lithium upgrade without overcomplicating the build.
Product Overview
The ALPHA 2 LITE is designed for customers who want a practical 12V lithium battery with strong storage capacity and dependable protection, without paying for extra premium features they may not need. It is a strong fit for RV solar battery banks, camper vans, travel trailers, boats, small cabins, sheds, and backup energy storage setups.
Compared with traditional lead-acid batteries, LiFePO4 chemistry offers longer service life, more usable energy, lower maintenance, and a lighter footprint. The ALPHA 2 LITE keeps the setup simple while delivering enough storage for serious mobile, marine, and off-grid power needs.
Built for RV, Marine, Cabin, and Off-Grid Power
The ALPHA 2 LITE gives 12V power systems a strong lithium storage upgrade with the capacity and protection needed for real travel, backup, and off-grid use. It works well for customers who want reliable battery storage for solar charging, lighting, electronics, DC loads, and inverter-supported essentials.
Key Features That Matter
The ALPHA 2 LITE keeps the focus on the features customers actually care about when choosing a 12V lithium battery: longer battery life, safer operation, usable capacity, compact sizing, and dependable LiFePO4 performance.
Built for 4,000 lifetime cycles, the ALPHA 2 LITE is designed to maintain consistent performance through years of regular use. That makes it a smart upgrade for customers who want longer-lasting storage than traditional lead-acid batteries.
The ALPHA 2 LITE is designed for real-world mobile and off-grid conditions. Low-temperature and overheat safety support helps make it practical for RV compartments, trailers, cabins, and seasonal power systems.
The built-in battery management system helps protect against overcharge, over-discharge, over-current, short-circuit conditions, and high or low temperature issues. That added protection is important for solar, mobile, marine, and backup power systems.
At 52.9 lb with a compact 20.9 x 8.1 x 8.5 in footprint, the ALPHA 2 LITE is easier to place in RV compartments, trailers, boats, and small off-grid setups while still delivering 2560Wh of lithium storage.
