CTEK D250SE 12V 20A Charger: Advanced Dual-Input DC-DC Battery Charger for RVs and Marine Use
Discover the CTEK D250SE 12V 20A Charger, a fully automatic 5-step dual-input DC-DC smart battery charger designed for charging and maintaining 12V lead-acid (WET, MF, Ca/Ca, AGM, EFB, GEL) and LiFePO4 lithium service batteries from 40Ah to 300Ah while on the move. Ideal for RVs, caravans, trucks, boats, and overlanding vehicles in South African conditions, this 12V 20A battery charger draws power from the alternator or solar panels via MPPT solar controller, delivering up to 20A output with selectable algorithms for AGM and lithium batteries to maximise lifespan and performance. Compatible with smart ECU-controlled alternators, the D250SE ensures stable charging even in variable loads, automatically redirecting maintenance power to the starter battery once the service battery is full, making it the ultimate 12V DC-DC charger for off-grid adventures.
Key features of the CTEK D250SE 12V 20A Charger include an integrated temperature sensor for optimised charging across -20°C to 50°C, preventing overcharge and sulphation in hot or cold South African climates, and battery separation that replaces diodes and VSR relays for efficient power management. With IP65 splash and dust protection, low ripple under 4%, and back current drain below 1Ah per month, this portable vehicle battery maintainer supports wind power inputs and pairs seamlessly with CTEK's Smartpass 120S for up to 140A systems. Its compact design (dimensions 198 x 93 x 51 mm, weight 0.6 kg) features simple LED indicators for real-time status, spark-free connections, and reverse polarity protection, ensuring safe operation without disconnecting the battery—perfect for marine battery charging or RV solar setups.
Enhance your dual-battery system with the CTEK D250SE 12V 20A Charger, offering reliable, temperature-compensated power solutions for automotive, caravan, and marine batteries in demanding South African environments, backed by a 2-year warranty and Swedish engineering excellence.
CTEK D250SE 12V 20A Charger: Dual-input DC-DC smart battery charger for 40-300Ah lead-acid, AGM, and LiFePO4 batteries. MPPT solar compatible, temperature sensor, smart alternator ready. Ideal 12V vehicle battery maintainer for RVs, boats, trucks in South Africa with 20A output and IP65 rating.
