Integrates natively with Apex300, AC200L, AC200MAX, AC300, and AC500 inverters. Reaches 80 percent charge in 45 minutes using 50A cables with compatible hosts. Scales to 58kWh maximum via 18-unit parallel arrays.\nSafety Features and Certifications: Internal battery management system enforces strict voltage and temperature limits. Automotive-grade LiFePO4 chemistry ensures thermal stability and suppressed thermal runaway risk.\nInstallation and Maintenance Requirements: Mount on flat, ventilated surfaces. Connect using designated parallel wiring harnesses only. Verify host firmware before initialization. Annual terminal inspection suffices; sealed modules require zero fluid maintenance.\nWarranty and Service Information: Four-year coverage for manufacturing defects and capacity deviation beyond rated cycles. Certified distributor network handles repair and module replacement.\nBranding\/References: Manufacturer: BLUETTI. Model: B300K (BlueCell 300). Technical documentation details electrical interfaces and host pairing matrices.\nDifferentiators: Single-bank scaling supports 18 synchronized units to 58kWh without auxiliary combiners. Dedicated 50A charging pathway cuts recovery time, maximizing generator efficiency during extended outages.\u003c\/div\u003e","brand":"Bluetti","offers":[{"title":"Default Title","offer_id":45315793944691,"sku":"P-B300K-UN-GY-BL-010","price":1167.6,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0683\/9969\/3939\/files\/19835dec0144b1a2214fef75157.webp?v=1786288326","url":"https:\/\/ampereauthority.com\/products\/bluetti-b300k-expansion-battery-2-764-8wh-for-apex300","provider":"Ampere Authority","version":"1.0","type":"link"}
