At a glance
High-spec features in a familiar 12V battery size
This page is for RS-B121SP. The ALPHA 1 PRO includes Bluetooth, internal heating and ETL listing to UL 1973. ALPHA 1 and ALPHA 1 LITE are different products with different feature and warranty packages.
System fit
Build around the battery’s voltage and 100A limits.
Use a LiFePO4-compatible charger with a 14.4V charge target and size the inverter, cabling, disconnect and overcurrent protection around the battery’s documented current limits. Maximum charge and continuous discharge are each listed at 100A; actual system design must also account for conductor length, ambient temperature and connected-load surge.

Common questions
ALPHA 1 PRO FAQ
How much energy does it store?
Nominal energy is 1,280Wh, calculated from the published 12.8V and 100Ah ratings. Usable energy depends on operating limits, temperature, load and system losses.
Does the heater let me charge at any temperature?
No. Follow the manual’s temperature and heater conditions. The heater requires charging input and is intended to warm the battery before normal charging continues.
Can I use it with my existing lead-acid charger?
Only if that charger has a charging profile and voltage settings approved for this LiFePO4 battery. Disable equalization and other lead-acid-only behaviors unless the battery manual explicitly permits them.
Can I put two batteries in series for 24V?
The current product-specific manual does not document series connection. Use a battery designed for the system’s native voltage instead.
