Engineered for demanding mobile applications including 4WD touring canopies, caravans, camper trailers, and marine vessels, this integrated system manages high-load energy storage alongside automated recharging from both vehicle alternators and solar arrays.\u003c\/p\u003e\n\n\u003ch3\u003eB-TEC Ultra 300Ah LiFePO4 Battery: Engineered for Harsh Environments\u003c\/h3\u003e\n\u003cp\u003eAt the core of this system is the B-TEC Ultra 300Ah lithium battery, constructed to withstand the rigours of Australian off-road and marine travel. Housed in a robust IP67-rated enclosure, the battery is protected against dust and water ingress. Unlike standard entry-level batteries that often suffer from voltage drop under heavy loads or fail in extreme climates, the B-TEC Ultra features a high-current internal Battery Management System (BMS) capable of supporting a 300A continuous discharge load. This allows you to run high-draw 12V appliances and large inverters simultaneously without tripping system protections.\u003c\/p\u003e\n\u003cp\u003eTo ensure reliable operation across diverse climates, the battery includes an integrated internal heater, allowing safe charging even when ambient temperatures drop below freezing. Cell-level IEC 62619 certification and a cycle life of 6,000 cycles at 80% depth of discharge reduce the risk of premature capacity degradation. Monitoring and system management are streamlined via smartphone Bluetooth connectivity, an onboard state-of-charge indicator, a physical on\/off isolating switch, and CAN\/RS485 communication ports.\u003c\/p\u003e\n\n\u003ch3\u003eEnerdrive DC2DC40+ Charger: Intelligent Multi-Source Power Management\u003c\/h3\u003e\n\u003cp\u003ePaired with the battery is the Enerdrive 12V 40A+ DC-DC charger, which ensures your 300Ah bank receives an accurate multi-stage charge profile. The unit features two independent inputs for engine alternator and solar panels, automatically selecting the active source without requiring external relays. It supports both 12V and 24V vehicle alternator systems (including smart alternators) and incorporates an efficient Maximum Power Point Tracking (MPPT) solar regulator to maximise energy harvest from unregulated solar panels.\u003c\/p\u003e\n\u003cp\u003eA critical advantage of the DC2DC40+ over basic chargers is its load-based regulation and power-supply mode. Once the lithium battery reaches the float stage, the charger transitions into a dedicated DC power supply. This supports your connected onboard loads directly from the solar or alternator input, preventing unnecessary micro-cycling of your battery bank and preserving full capacity for overnight use.\u003c\/p\u003e\n\n\u003ch3\u003eKey Features and System Benefits\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eHigh-Output Lithium Storage:\u003c\/strong\u003e 300Ah capacity with a 300A continuous discharge rating and dual M8 positive and negative terminals for secure, high-load cable connections.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAll-Weather Durability:\u003c\/strong\u003e IP67 water and dust resistance paired with an internal battery heater for safe sub-zero charging.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDual-Input DC-DC Charging:\u003c\/strong\u003e Automatically switches between 12V\/24V vehicle alternators and solar inputs via the built-in MPPT solar controller.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAdvanced Diagnostics and Control:\u003c\/strong\u003e Real-time monitoring via the B-TEC Bluetooth app, an onboard battery SoC indicator, and a programmable backlit LCD screen on the charger.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eScalable Architecture:\u003c\/strong\u003e Supports series and parallel configurations (up to 4 batteries in series or parallel) for future system expansion.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInstallation Hardware Included:\u003c\/strong\u003e Supplied with a dedicated battery mounting tray, tie-down straps, and a charger temperature sensor for optimised voltage compensation.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eUpgrade Your Off-Grid Power Architecture\u003c\/h3\u003e\n\u003cp\u003eConfigure your touring vehicle, caravan, or marine vessel with the Enerdrive B-TEC 300Ah and DC2DC40+ bundle to secure dependable, high-capacity 12V power for extended off-grid travel.\u003c\/p\u003e","brand":"Enerdrive","offers":[{"title":"Default Title","offer_id":43639504502845,"sku":"K-300-12","price":3685.77,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0602\/3918\/3933\/files\/enerdrive-12v-300ah-b-tec-lithium-battery-dc2dc40-charger-k-300-12.png?v=1792906727","url":"https:\/\/www.solar4rvs.com.au\/products\/enerdrive-b-tec-bundle-with-12v-300ah-lithium-battery-and-12v-dc2dc40-charger","provider":"Solar 4 RVs","version":"1.0","type":"link"}
