12V Lithium Battery · LiFePO4 · Best Value
1,280Wh of Lightweight Power at an Accessible Price
The ALPHA 1 LITE is Rich Solar’s entry-level 12V 100Ah LiFePO4 battery — built with EV-grade A+ cells rated for 4,000+ cycles, with a smart BMS and passive cold-weather protection, sized for RVs, trailers, vans, boats, and off-grid use.
EV-Grade Cells, Entry-Level Price
The ALPHA 1 LITE is the entry point into Rich Solar’s ALPHA 1 lineup, built with the same automotive-grade LiFePO₄ technology as the standard ALPHA 1 and ALPHA 1 PRO. It’s rated for 4,000+ deep cycles at 80% depth of discharge, delivers the same power as a comparable lead-acid battery at roughly one-third the weight, and carries excellent thermal and chemical stability with no fire or explosion risk.
It focuses on core reliability rather than connected features — no Bluetooth app and no active self-heating, just a smart BMS and passive temperature protection, at the most accessible price point in the ALPHA 1 lineup.

Common Questions
How is the LITE different from the ALPHA 1 and ALPHA 1 PRO?
All three share the same 12.8V 100Ah, 1,280Wh core. The LITE is the value-focused entry point — it has neither Bluetooth monitoring nor active self-heating, which both the standard ALPHA 1 and ALPHA 1 PRO include, and is rated for 4,000+ cycles versus their 5,000 and 7,000.
Does it have Bluetooth monitoring?
No — Bluetooth app monitoring is available on the standard ALPHA 1 and ALPHA 1 PRO, not the LITE.
Does it actively heat itself in cold weather?
No — the LITE uses passive protection rather than an active heater. Charging simply stops below 32°F to prevent damage, rather than warming the battery to a safe charging temperature.
How long does it take to fully charge?
About 6 hours with a dedicated LiFePO4 charger (14.4V, 20A) or a 20A DC-DC generator charger, or roughly one sunny day with 400W+ of solar input.
What’s the warranty on this battery?
