9-36V To 16.8V DC-DC Lithium Battery Charger - 2A Output, For 12V Systems In Cars, RVs, Boats

Need a smart way to charge a 12V lithium or lead-acid battery from a higher voltage source in your vehicle, RV, or boat? This DC-DC converter/charger takes an input voltage from 9V all the way up to 36V (so it can work from a 24V truck system or a variable solar input) and outputs a steady 16.8V for charging 4-cell lithium iron phosphate (LiFePO4) batteries, or it can be set to other voltages like 13.8V for lead-acid maintenance. This specific model is listed with a 2A output current, which is good for trickle charging or maintaining smaller battery banks. It's a compact unit meant for travel battery systems, camper vans, or any application where you need to step down a vehicle's DC voltage to safely charge an auxiliary battery. Always check the required charging voltage for your specific battery type before using. Installation requires basic wiring skills: connect input to your source (with a fuse!), and output to your battery. A handy tool for DIY power setups, ensuring your accessory battery gets charged properly without overcharging. Perfect for off-grid enthusiasts, van lifers, or anyone with a dual-battery system. Keep your power topped up on the go.
