{"product_id":"alpha-4-24v-100ah-lifepo4-battery","title":"ALPHA 4 - 24V 100Ah LiFePO4 Battery","description":"\u003cp\u003eA 25.6V nominal battery holding 2,560Wh - the same energy as a 12V 200Ah unit, but delivered at twice the voltage so your cable runs carry half the current. If your inverter and charge controller are 24V, this is the drop-in unit.\u003c\/p\u003e\u003ch2\u003eWhy this battery\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003e2,560Wh from 100Ah at 25.6V nominal. Halving the current for the same power means smaller cable, smaller fuses and less voltage drop across a long run - the practical reason to go 24V.\u003c\/li\u003e\n\u003cli\u003eRated for 5,000 cycles, with a published 5-year warranty.\u003c\/li\u003e\n\u003cli\u003e100A BMS: 100A maximum charge, 100A continuous discharge, 110A for ten seconds.

Note that heating draws about 100W from an external source while it runs - budget for that in a solar-only system in winter.\u003c\/li\u003e\n\u003cli\u003eBluetooth monitoring through the RICH SOLAR app.\u003c\/li\u003e\n\u003cli\u003eIP65 rated, in a flame-retardant ABS housing.\u003c\/li\u003e\n\u003cli\u003e48.5 lb and 20.9 x 8.1 x 8.5 in - long and narrow rather than a standard group size, so measure your compartment before ordering.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eInstallation\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eCharge method is CC\/CV. \u003cstrong\u003eNote on charge voltage:\u003c\/strong\u003e Rich Solar's own page lists 14.4V ± 0.2V, which is the figure for their 12V batteries and cannot be right for a 25.6V nominal pack - a 24V LiFePO4 battery charges at roughly twice that. Take the charge voltage from the specification PDF or the manual and confirm it with Rich Solar before you set your controller. Charging a 24V battery at a 12V setpoint will simply never fill it.\u003c\/li\u003e\n\u003cli\u003eRecommended charge current is 50A; the BMS will accept up to 100A.\u003c\/li\u003e\n\u003cli\u003eCharge between 32°F and 131°F, discharge between -4°F and 140°F, store between 14°F and 95°F.\u003c\/li\u003e\n\u003cli\u003eThe heater needs external power to run - it will not heat the battery from its own cells.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eWarranty\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003e5-year limited warranty published by Rich Solar.\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":46391896113302,"sku":"RS-B241S","price":799.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0676\/5291\/1254\/files\/01-2.jpg?v=1785821510","url":"https:\/\/sunenergydepot.com\/products\/alpha-4-24v-100ah-lifepo4-battery","provider":"sunenergydepot.com","version":"1.0","type":"link"}
