24V Lithium Battery · LiFePO4 · Bluetooth
The ALPHA 4 is Rich Solar's full-featured 24V 100Ah LiFePO4 battery — rated for 5,000+ cycles, with Bluetooth app monitoring and internal self-heating technology built in for cold-weather charging, sized for RVs, trailers, vans, boats, and off-grid systems.
The ALPHA 4 is the flagship version of Rich Solar's ALPHA lineup, built on the same 24V 100Ah LiFePO4 chemistry as the ALPHA 4 LITE but with real upgrades: a higher 5,000+ cycle rating, Bluetooth app connectivity for real-time monitoring, and internal self-heating technology that keeps charging safe in cold weather.
It's designed for anyone who wants to check on their battery's state of charge, temperature, and health from a phone rather than guessing — while still fitting the same footprint and use cases as the rest of the lineup: RVs, trailers, vans, boats, and off-grid systems.

*As listed on Rich Solar's own specification page. This figure is lower than the 28.8V charge voltage stated for the ALPHA 4 LITE, a comparable 24V battery — worth confirming with Rich Solar before using it to configure charging equipment.
Both share the same 24V 100Ah LiFePO4 chemistry, but the ALPHA 4 adds Bluetooth app monitoring, internal self-heating for cold-weather charging, and a higher 5,000+ cycle rating versus the LITE's 4,000+.
Real-time state of charge, voltage, and temperature, so the battery's status can be checked from a phone instead of an onboard display — a companion quick-start guide covers app setup.
Yes — built-in self-heating automatically activates below 41°F and shuts off once the battery warms past 50°F, drawing 100W of external power while active.
It's rated for 5,000+ charge cycles and carries a 5-year warranty.
It carries an IP65 protection rating with a flame-retardant ABS housing, suited to the kind of exposure typical in RV, van, and marine installations.
