{"product_id":"alpha-1-12v-100ah-lifepo4-battery","title":"ALPHA 1 - 12V 100Ah LiFePO4 Battery","description":"\u003cp\u003eA 12.8V 100Ah drop-in lithium battery for RVs, vans, boats and cabins that have to charge in the cold. The ALPHA 1 warms its own cells before accepting a charge below 41°F, which is the point at which most lithium batteries left in an unheated bay simply stop taking a charge for the winter.\u003c\/p\u003e\u003ch2\u003eWhy this battery\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003e1,280Wh of storage from 100Ah at 12.8V nominal, with 100A continuous discharge - enough headroom for a 1,000W inverter load.\u003c\/li\u003e\n\u003cli\u003eRated for 5,000+ cycles. At one cycle a day that is roughly thirteen years of service, against three to five years from a comparable AGM bank.\u003c\/li\u003e\n\u003cli\u003eA heating element inside the case switches on automatically below 41°F and shuts off once the cells pass 50°F. Charging is blocked outright below 32°F so the cells are never plated.\u003c\/li\u003e\n\u003cli\u003eBluetooth monitoring through the Rich Solar app reports state of charge, voltage, current, temperature and remaining capacity, and can switch the battery output on or off remotely. Pairing is a barcode scan.\u003c\/li\u003e\n\u003cli\u003eThe built-in BMS covers overcharge, over-discharge, overcurrent, short circuit, temperature limits and cell balancing.\u003c\/li\u003e\n\u003cli\u003eAt 24 lb it weighs roughly a third of the lead-acid bank it replaces at equivalent usable capacity.\u003c\/li\u003e\n\u003cli\u003eWorth knowing before you buy: the ALPHA 1 is not UL1973 certified. If your install has to satisfy an inspector or insurer who asks for a listed battery, the ALPHA 1 PRO carries that certification along with a 7,000-cycle rating, for about a hundred dollars more.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eInstallation\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eThe case measures 10.2 x 6.6 x 8.3 in - a Group 24 footprint - so it drops into most existing battery trays without modification.\u003c\/li\u003e\n\u003cli\u003eCharge with a LiFePO4 profile at 14.4V ± 0.2V. A 20A lithium charger brings it to full in about six hours.\u003c\/li\u003e\n\u003cli\u003eRoughly 400W of solar will recover a full charge over one clear day.\u003c\/li\u003e\n\u003cli\u003eFrom an alternator or generator, a 20A DC-DC charger takes about six hours.\u003c\/li\u003e\n\u003cli\u003eCharging window is 32°F to 131°F; discharge runs from -4°F to 140°F.\u003c\/li\u003e\n\u003cli\u003eMaximum charge current is 100A, so size charge controllers and DC-DC chargers accordingly.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eWarranty\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eCovered by Rich Solar's limited warranty. The ALPHA 1 is not published with the 10-year term that applies to the PRO model - if warranty length is a deciding factor, ask us to confirm the current term before you order.\u003c\/li\u003e\n\u003cli\u003eCalifornia Proposition 65 warning applies: this product can expose you to chemicals known to cause cancer and reproductive harm.\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"RICHSOLAR","offers":[{"title":"Default Title","offer_id":46391895851158,"sku":"RS-B121S","price":399.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0676\/5291\/1254\/files\/ALPHA112V100AhLITHIUMBATTERY20251121_1.jpg?v=1785820815","url":"https:\/\/sunenergydepot.com\/products\/alpha-1-12v-100ah-lifepo4-battery","provider":"sunenergydepot.com","version":"1.0","type":"link"}
