Frequently Bought Together
Rich Solar ALPHA 1 12V 100Ah LiFePO4 Battery
The Rich Solar ALPHA 1 is a compact 12V 100Ah lithium iron phosphate battery built for RVs, trailers, vans, boats, cabins, camping setups, and off-grid solar systems. With 1280Wh of usable storage, internal heat technology, Bluetooth real-time monitoring, 5,000+ lifetime cycles, BMS safeguards, and Premium A+ Grade Cells, it gives smaller 12V power systems a smarter lithium battery upgrade.
Product Overview
The ALPHA 1 is designed for customers who want a reliable 12V lithium battery in a compact, easy-to-install size. It is a strong fit for RV solar battery banks, camper vans, travel trailers, boats, small cabins, sheds, camping power systems, and backup power setups where clean energy storage and dependable battery life matter.
Compared with traditional lead-acid batteries, LiFePO4 chemistry provides longer service life, more usable energy, better weight savings, and lower maintenance. The ALPHA 1 adds internal heating and Bluetooth monitoring, making it a practical upgrade for customers who want more control and confidence from a 12V battery.
Built for RV, Marine, Cabin, and Off-Grid Power
The ALPHA 1 gives smaller 12V systems a stronger lithium storage foundation for everyday travel, backup, and off-grid use. It is ideal for customers who need reliable energy for lighting, electronics, DC loads, small inverters, solar charging, and essential mobile power.
Key Features That Matter
The ALPHA 1 focuses on practical upgrades customers can actually use: cold-weather support, real-time app monitoring, BMS protection, efficient LiFePO4 cells, and flexible charging options.
Internal heating helps improve cold-weather usability for RVs, trailers, cabins, marine compartments, and seasonal off-grid systems. Charging pauses below freezing, heating starts in low temperatures, and heating stops once the battery reaches a safer operating range.
Built-in Bluetooth monitoring lets users track battery status from a mobile device, including state of charge, voltage, current, temperature, and remaining capacity. It gives customers easier visibility without relying on guesswork.
The built-in Battery Management System helps protect the battery from overcharge, over-discharge, over-current, short-circuit conditions, cell imbalance, and temperature-related issues during daily use.
Advanced EV-grade LiFePO4 cells help deliver smarter performance, longer battery life, and better energy density. The ALPHA 1 is designed for 5,000+ cycles, improved efficiency, and a much lighter footprint than lead-acid battery options.
Three Practical Charging Options
The ALPHA 1 can be charged through common off-grid and mobile power methods, giving customers flexibility whether they are at home, at a campsite, or building a solar-powered setup.
