24V Lithium Battery · LiFePO4 · 100Ah
2,560Wh of Dependable Power With Individually Fused Cells
The ALPHA 4 LITE is Rich Solar’s value-focused 24V 100Ah LiFePO4 battery — rated for more than 4,000 cycles, built with individually fused lithium cells, and sized for RVs, trailers, vans, boats, and off-grid backup power.
Built to Just Work
The ALPHA 4 LITE is designed for people who want a battery that simply performs, without extra complexity or cost. It packs 2,560Wh of usable energy into a durable, lightweight case, using individually fused lithium cells so a single cell fault can’t take down the whole pack.
As the value-focused version of Rich Solar’s ALPHA 4 lineup, it’s built around the same core LiFePO4 chemistry and 4,000+ cycle rating as the standard ALPHA 4, aimed at anyone who wants dependable power for the road or off-grid without paying for features they won’t use.

Where It Fits
Common Questions
How is the LITE different from the standard ALPHA 4?
The ALPHA 4 LITE shares the same 24V 100Ah LiFePO4 chemistry and 4,000+ cycle rating as the standard ALPHA 4, positioned as the more affordable, value-focused option in the lineup.
What does “individually fused cells” mean?
Each lithium cell in the pack has its own fuse, so if a single cell develops a fault, it’s isolated rather than affecting the rest of the battery.
How much usable energy does it store?
2,560Wh at a 25.6V nominal voltage and 100Ah capacity, with a minimum rated capacity of 99.5Ah.
What protections does the BMS include?
Over-charge protection, over-discharge protection, and short-circuit protection, each with specific voltage thresholds and recovery points managed automatically by the battery management system.
Can it be charged in cold weather?
Charging is rated from 32°F to 131°F. Discharging has a wider range, down to -4°F, but charging below freezing isn’t recommended for this battery.
What’s the warranty?
The ALPHA 4 LITE carries a 5-year warranty.
