Rich Solar ALPHA 2 12V 200Ah LiFePO4 Battery
The Rich Solar ALPHA 2 is a powerful 12V 200Ah lithium iron phosphate battery built for RVs, trailers, vans, boats, cabins, DIY solar systems, and off-grid power setups. With 2560Wh of storage, internal heat technology, built-in Bluetooth real-time monitoring, and 5,000+ lifetime cycles, it gives mobile and off-grid systems a dependable lithium battery foundation.
Product Overview
The ALPHA 2 is designed for customers who need more usable 12V battery capacity without building a complicated battery bank from multiple smaller batteries. It is a strong fit for RV solar systems, camper vans, travel trailers, boats, cabins, sheds, and off-grid energy storage setups.
Compared with traditional lead-acid batteries, LiFePO4 chemistry delivers longer service life, stronger usable capacity, lower maintenance, and more consistent performance over time. The ALPHA 2 adds internal heating and Bluetooth monitoring, making it a more complete choice for real-world mobile and off-grid power.
Built for RV, Marine, Cabin, and Off-Grid Power
The ALPHA 2 gives 12V power systems a strong lithium storage upgrade with the capacity and features needed for real travel, backup, and off-grid use. It is ideal for customers who want a reliable battery for solar charging, essential appliances, DC loads, lighting, electronics, and inverter-based systems.
Key Features That Matter
The ALPHA 2 includes the features customers actually care about when choosing a 12V lithium battery: cold-weather support, mobile battery monitoring, long cycle life, strong usable capacity, and dependable LiFePO4 performance.
Internal heating helps improve cold-weather usability for RVs, trailers, cabins, marine storage areas, and seasonal off-grid systems where low temperatures can affect battery charging.
The built-in Bluetooth module lets users monitor battery operation status from a mobile device, giving quick visibility into battery condition without needing to guess.
Designed for consistent and durable performance, the ALPHA 2 gives solar, RV, marine, and off-grid users a longer-lasting battery option than traditional lead-acid storage.
