Experience seamless power distribution with the CTEK Smartpass 120S 12V 120A Power Management System, a cutting-edge fully automatic solution designed to maximise alternator output for charging and maintaining 12V lead-acid and LiFePO4 service batteries from 28Ah to 800Ah. Ideal for caravans, RVs, trucks, boats, and overlanding vehicles in South African conditions, this 120A battery charger system intelligently separates starter and service batteries, prioritising critical equipment like radios, navigation systems, and emergency lights through its advanced Battery Guard function. Compatible with all alternator types, including smart alternators, the Smartpass 120S delivers up to 120A current for fast charging even on short journeys, preventing total discharge and incorporating over-temperature protection to reduce charge current before battery temperatures exceed safe levels from -20°C to 50°C.

Key features of the CTEK Smartpass 120S 12V 120A Charger include a Start Assistance mode that diverts power from the service battery to jump-start the vehicle if the starter battery is flat, ensuring uninterrupted operation in remote areas. With IP65 splash and dust protection, low back-current drain, and no need to disconnect the battery, this portable power management unit safeguards sensitive electronics from overcharge or undercharge, making it perfect for dusty or humid South African environments. Pair it with the D250SE or D250SA 20A onboard chargers for an ultimate 140A system, supporting MPPT solar inputs and automatic energy management for off-grid adventures, while its compact dimensions (198 x 93 x 51 mm) and lightweight 0.6 kg design allow easy installation in tight spaces.
