STYLE : Weatherproof – polycrystalline, aluminium frame with 4 x mounting brackets, output cable 200cm / 80″ with SAE connector. OptiMate Charge controller: CHARGING AMPS : 1.67A from 20W panel (max. average current), 3-5A pulse current USE : Indoor / Outdoor (lowest temperature: -4°F / -20°C). SAVE : Low Volt Start of 4V IDEAL FOR : STD, AGM & GEL 12V batteries from 2 – 240Ah and Lithium LFP 12.8V / 13.2V batteries INPUT : 15 – 22V STYLE : Weatherproof charge controller case. INCLUDED: Weatherproof battery lead, standard battery clip set & 20W solar panel SAFE: No risk of overcharging. Totally safe for vehicle electronics. Sparks suppressed. Safe for long-term battery maintenance. Automatic shut-down if short-circuited or battery disconnected. Charge : Saves flat batteries from as low as 4V with its unique pulse action. Fastest charge is delivered as ‘smart charge’ control selects pulse or continuous charge according to sunlight strength. Intelligent maintenance continues the next day if battery retained charge overnight, otherwise the program reverts to OPTIMIZE step. Monitor : Battery condition is displayed every 3 seconds. Ready indication for STD, hi-performance AGM and lithium LFP batteries. Draws less than 0.5mA during monitor mode. Automatically switches to CHARGE when solar power is sufficient. Mounting The OptiMate DUO charger-monitor controller is separate to the solar panel and can be placed close to the vehicle or battery so that charge and maintenance progress can be easily followed. The solar panel must be mounted and angled to receive direct sunlight. The reach / distance between battery and panel is 315cm / 124″. To extend, use OptiMate Cable Extenders O-03, O-13 or O-23 and insert between the solar panel and the OptiMate DUO charge-monitor controller
